Part No. 0017576 Rev. A 2/06 ©2006 LOUD Technologies Inc. All Rights Reserved. R Owner’s Manual 3 M-Series Introduction Thank you for choosing a Mackie high-efficiency power amplifier. We appreciate your vote of confidence for the folks in Woodinville who specialize in awesome and affordable professional audio designs. while minimizing Class-H switching distortion. The bottom line is the M-Series amplifiers achieve some of the lowest distortion numbers in the business without resorting to substantial amounts of negative feedback. The Mackie M-Series power amplifiers have a wide variety of features that set them apart from any other amplifier in their price range. • That’s Not All! • More Output Devices The more output devices that are used in a power amplifier, the more reliably the amplifier will operate over the long-term at high power levels into low-impedance loads. The M-Series amplifiers typically use more output devices for the same output power than our competitors amplifiers. This means the output devices are required to handle less power, thus drastically extending the lifeexpectancy of our amplifiers. • True 2-ohm Power Capability Some amplifier manufacturers present their power ratings into 2-ohms at 1 kHz. Because our M-Series power amplifiers use more output devices, they can provide full-power into 2-ohms over the entire audio frequency range, from 20 Hz to 20 kHz, all night long! • Higher Efficiency The M•2000 uses a highly efficient two-rail Class-H topology, while the M•3000 and M•4000 use an even more efficient three-rail Class-H topology. This allows the amplifiers to run cooler, even in high-ambient temperatures, while improving their long-term reliability. • Lower Distortion Our design engineers have paid particular attention to reducing distortion in the M-Series amplifiers. From triple darlington output stages to a fully complementary/ differential design from input to output, to the Mackie exclusive adaptive slew Class-H switching design that allows the amplifiers to pass the fastest transient peaks Please write your serial number here for future reference (i.e., insurance claims, tech support, return authorization, etc.) Purchased at: Date of purchase: 4 M-Series There are plenty more features that make your selection of a Mackie M-Series power amplifier a good investment, from the Fast Recovery design pioneered in our FR Series amplifiers, to the quiet fans and constant thermal gradient heatsinks to dissipate heat away from the output devices evenly and efficiently, to the extensive protection circuits designed to protect the amplifier and your loudspeakers. HOW TO USE THIS MANUAL We know that many of you can’t wait to get your new amplifier hooked up, and you’re probably not going to read the manual first (sigh!). So the next section is a Quick-Start Guide to help you get the amplifier set up fast so you can start using it right away. Right after that are the ever popular hook-up diagrams that show typical setups for live sound applications. Then, when you have time, read the Features Description section. This describes every knob, button, and connection point on the M-Series amplifiers. Throughout this section you’ll find illustrations with each feature numbered. If you want to know more about a feature, simply locate it on the appropriate illustration, notice the number attached to it, and find that number in the nearby paragraphs. This icon marks information that is critically important or unique to the M-Series amplifiers. For your own good, read them and remember them. They will be on the final test. This icon leads you to in-depth explanations of features and practical tips. While not mandatory, they usually have some valuable nugget of information.

The FAQ (Frequently Asked Questions) section is filled with answers to many of the questions our Technical Support staff has fielded over the years. Check out the glossary for explanations of many of the pro-audio terms used in our manuals. Visit our forums to seek help from our online community of Mackie users. • The 1/4" TRS inputs are wired tip = hot (+), ring = cold (–) and sleeve = shield (ground), and can accept either balanced (TRS) or unbalanced (TS) cables. READ THIS PAGE!! Even if you’re one of those people who never read manuals, all we ask is that you read this page now before you begin using the M-Series power amplifier. You’ll be glad you did! IMPORTANT: The amplifier draws its ventilation air in from the rear and out through the front panel. It needs plenty of fresh air to stay cool. DO NOT BLOCK THE VENTILATION PORTS! • The screw terminal inputs are wired as indicated: hot (+), cold (–), and ground (GND). 7. In MONO and BRIDGE modes, the signals appearing at Channel 1 and Channel 2 inputs are summed together to create a mono signal. 8. In STEREO and MONO modes, connect speaker cables to the SPEAKER OUTPUTS, either binding posts or Speakons®: • The binding post connectors are wired red = hot (+) and black = cold (–). • The Speakon connectors are wired as follows: Channel 1 pin 1+ = Ch 1 hot (+) and pin 1– = Ch 1 cold (–) pin 2+ = Ch 2 hot (+) and pin 2– = Ch 2 cold (–) Connections and Settings 1. Turn down the channel Gain controls. 2. Set the 150 Hz X-OVER switches to FULL. 3. Set the LIMIT switches ON. 4. Turn the POWER switch off. 5. Determine which AMP MODE is best for your application. • STEREO mode (separate left and right inputs, separate left and right outputs) is the typical setup for amplifying stereo signals. • MONO mode (sometimes called Dual-Mono mode — one mono input, two mono outputs) is for sending a mono signal to two different speaker sets, with separately-adjustable level controls. • BRIDGE mode (sometimes called Bridged-Mono — one mono input, one mono output) uses both sides of the amp to double the power to one speaker set. Note: 4 ohms is the minimum impedance you should connect to the amplifier in BRIDGE mode (2 ohms in MONO or STEREO modes). If you connect a lower impedance load, the SHORT LEDs may light, putting the amplifier into PROTECT mode. Set the AMP MODE switch accordingly. 6. In STEREO mode, connect line-level cables from your signal source to the M-Series amplifier’s INPUT jacks, either XLR, TRS, or screw terminals: • All the inputs and thru jacks for each channel are wired in parallel. • The balanced XLR inputs are wired pin 2 = hot (+), pin 3 = cold (–) and pin 1 = shield (ground). Owner’s Manual Getting Started Channel 2 pin 1+ = Ch 2 hot (+) and pin 1– = Ch 2 cold (–) pin 2± = unused BRIDGE pin 1+ = hot (+) and pin 1– = cold (–) pin 2± = unused 9. In BRIDGE mode, connect the binding post cable like this: the hot (+) side goes to the CHANNEL 1 SPEAKER OUTPUTS red post and the cold (–) side goes to the CHANNEL 2’s red post. Connect nothing into the black posts. 10. Connect the other ends of the speaker cables to your loudspeakers. 11. Plug the amplifier’s power cord into an outlet properly configured with the correct voltage for your amplifier, and capable of delivering enough current to reach full power. 12. Make sure your signal source (feeding the amplifier’s inputs) is powered up and delivering signal to the amp. 13. Turn the amplifier’s POWER switch on and verify that the signal present (SIG) LEDs are blinking. 14. Slowly turn both Gain controls up: You should hear the music and see the SIG and meter LEDs flashing. If the topmost LEDs (named OL, for OverLoad) are flashing, turn down either the Gain controls on the amp or the source signal’s output level controls (i.e., master faders). The point is: The OL LEDs should only occasionally light up. Frequent lighting of the the OL LEDs indicates that the amplifier is being driven too hard and clipping distortion is likely audible. Owner’s Manual 5 M-Series 15. For quieter listening, it is preferable to adjust the amplifier’s gain controls rather than the source signal’s output level (unless you have the source’s control all the way up!). Other Nuggets of Wisdom • For optimum sonic performance, the channel and main mix faders on your mixer should be set near the “U” (unity gain) markings. Then adjust the amplifier’s gain control to attain the desired volume through the loudspeakers. • Never plug amplifier outputs into anything except speakers (unless you have an outboard box specifically designed to handle speaker-level signals). • Before making connections to an amp or reconfiguring an amp’s routing, turn the amp’s level (Gain) controls down, turn the power off, make the changes, turn the power back on, and then turn the level controls back up. • When you shut down your equipment, turn off the amplifiers first. When powering up, turn on the amplifiers last. • Never listen to loud music for prolonged periods. Please see the Safety Instructions on page 2 for information on hearing protection. • Save the shipping box! You may need it someday, and you don’t want to have to pay for another one. That’s it for the “Getting Started” section. Next comes the “Hookup” section that shows you some typical ways that you might use the M-Series amplifier in real applications. After that, take the grand tour of the amplifier, with descriptions of every knob, button, input, and output. We encourage you to take the time to read all of the feature descriptions, but at least you know it’s there if you have any questions. 6 M-Series Owner’s Manual Hookup Diagrams OPTIONAL CONNECTION USING BINDING POSTS TO SPEAKERS FROM MIXING CONSOLE LEFT AND RIGHT MAIN OUT SPEAKER OUTPUTS + BRIDGE + + SPEAKER OUTPUTS + CAUTION LETHAL VOLTAGES MAY APPEAR AT OUTPUT TERMINALS.

M-Series Power Amplifier: Two Amps Using Built-in X-over Owner’s Manual 9 M-Series M-Series Features Front Panel Much of the front panel of the M-Series amplifiers is comprised of ventilation slots for expelling warm air from the inside of the amplifier. Be sure to leave space in front of the amplifier for proper ventilation to occur. 1. Gain Control These knobs control the levels to the output section of the M-Series amplifiers. You’ll notice that their travel is detented, meaning there are 21 built-in “resting points” so you can easily set both controls to the same level. Usually, these controls are set all the way up. The gain structure of the amplifier is designed so that a +4 dBu (1.23V rms) input signal drives the amplifier to full power into 4 ohms. M•2000 = 525 watts/channel into 4 ohms M•3000 = 800 watts/channel into 4 ohms M•4000 = 1050 watts/channel into 4 ohms This is how the sensitivity of an amplifier is defined (the input voltage required to attain maximum output power into a specified load impedance). In this case, it equates to a voltage gain of 31.4 dB for the M•2000, 33.3 dB for the M•3000, and 34.4 dB for the M•4000). You can set the Gain controls as low as you like. However, reducing the Gain controls requires an increased input level to reach full power at the amplifier’s output. Like all amplifier controls, you’ll typically determine the optimal settings during installation or sound check, then leave them alone, using your signal source (usually a mixer) to control listening levels as you work. Or play. 2. Meters The M-Series amplifier’s meters indicate the relative output level of the amplifier referenced to full power. The numbers next to the meter’s LEDs are in dB below full power. Ideally, the –20, –9, –6, and –3 LEDs will light and blink at normal signal levels, while the OL LED may flicker occasionally during peak moments. OL is short for Overload. Overloading, or clipping, occurs when the output voltage no longer linearly follows the input voltage and simply stops. This causes a sine wave to “square off,” or get “clipped off.” Thus, the term clipping. Fear not — this scenario is quite unlikely. Even with the Gain controls fully up, the M-Series amplifier easily accepts professional “+4 dBu” operating levels. With the Gain control all the way up (fully clockwise), the input sensitivity is 1.23V, which works well with professional equipment operating at a nominal +4 dBu level. If the OL (Overload) LED is blinking frequently or continuously, turn down the amplifier’s Gain control or the source signal (i.e., the mixer’s master faders). On the other hand, you may want your listening level to be quieter than the M-Series amplifier’s maximum level. For instance, if you’re using the amplifier as a control room amp, and your control room is the size of a telephone booth, you’ll probably never want to hear the amp at its maximum level. M.4000 HIGH EFFICIENCY POWER AMPLIFIER 1 INTERNAL STATUS PROTECT SHORT OVER TEMP OO MAX 2 OL OL -3 -3 -6 -6 INTERNAL STATUS -9 -9 PROTECT -20 -20 SHORT SIG OVER TEMP SIG OO MAX POWER 10 M-Series If the PROTECT LEDs are on, the amplifier’s output section has shut down. That, of course, means you won’t hear anything until you rectify the situation. Three things can cause the PROTECT circuit to engage: 1. Powering up the amplifier. A built-in delay circuit saves your speakers (and ears) from the thumps or pops that can sometimes occur when powering up a system. During this three-second delay, the PROTECT LEDs light up. 2. A short circuit (or near short) in either of the outputs. Both the PROTECT and the SHORT LEDs light up. 3. The temperature in the amplifier has risen to an unsafe level. The PROTECT and the OVER TEMP LEDs light up. The M-Series amplifier draws its ventilation air in from the rear and out through the front. The amp needs plenty of fresh air to stay cool. DO NOT BLOCK THE VENTILATION PORTS. See “Thermal Considerations” on page 16 for more details. Note: In the unlikely event that the power transformer overheats (in general, this cannot happen during normal use — but could occur when bench testing at high power levels for an extended period of time), the PROTECT LED will light, but not the OVER TEMP LED. It takes from one to two hours for the transformer to cool to a safe temperature, when normal operation resumes. 4. SHORT Indicator If this LED comes on, the amplifier has detected a short circuit (or near short) in either of the outputs, meaning that the hot (+) and cold (–) speaker wires are touching, or a speaker itself is shorted out. Such a condition causes the amplifer to engage its Protect mode, muting all signals at the amp’s outputs. This short-circuit LED is a Mackie exclusive and can save precious minutes of your troubleshooting time. Without it, you’d still have speaker and amp protection (via the PROTECT circuit), but you wouldn’t be able to determine the source of the problem. But with the SHORT LED, the M-Series amplifier comes right out and tells you! WARNING: The SHORT LEDs indicate an unsafe condition for the power amplifier. When the shortcircuit protection is activated, the SHORT LED lights, then the PROTECT LED lights and the SHORT LED turns off. After about four seconds, the protection circuit turns off and the amplifier resumes normal operation. If it senses the shorted condition again, the cycle repeats until you fix the problem. Typical causes for a “short” indication would be either a shorted speaker cable or too many speaker cabinets connected to the amplifier (i.e., the load impedance is too low). If a “short” is indicated, please check your cables. If the cabling is OK, then reduce the number of cabinets driven by the amplifier. Note: When using the amplifier in BRIDGE mode, one or both SHORT LEDs may light under shorted or low impedance conditions. Regardless of whether one or both LEDs light, it’s an indication of a problem that requires further investigation. Owner’s Manual 3. PROTECT Indicator 5. OVER TEMP Indicator OVER TEMP (short for over-temperature) is another feature designed to keep your mind at ease. Under extreme conditions the amplifier may overheat. You may ask, “What kind of extreme conditions?” Overheating problems are usually caused by one of the following situations: improper ventilation, high ambient temperatures, overdriving the amplifier into clipping, driving the amplifier hard into low-impedance loads, frayed or partially shorted speaker cables, or defective or internally shorted speakers. The heaviest load the M-Series amplifier can tolerate is 2 ohms per channel (4 ohms in bridged mode). If you’ve got a set of speakers wired in parallel, be sure the load isn’t adding up to less than 2 ohms. Anything below 2 ohms can cause the SHORT LED to light and trigger the PROTECT mode, or cause the amplifier to overheat, which also triggers the PROTECT mode. Note: Since each channel has its own temperature sensor and protection circuit, it is possible for only one channel to go into PROTECT mode while the other channel continues to operate. As the internal temperature of the amplifier rises, the fans turn on at 50°C (122°F), and they kick into high speed at 65°C (149°F). More air moves through the constant temperature gradient cooling tunnel to remove additional heat from the output transistors. However, if the internal temperature of the amplifier should exceed 85°C (185°F), the OVER TEMP LED turns on, and both PROTECT LEDs shine. The output of the amplifier is muted — at this point the amplifier is in Protect mode and remains there until the internal temperature cools off to a safe level (60°C or 140°F). When this occurs, the OVER TEMP and PROTECT LEDs turn off, and normal operation resumes. Owner’s Manual 11 M-Series Rear Panel Be Aware: If the OVER TEMP LED comes on frequently, something is overworking the amplifier or it’s not properly ventilated. Look at each of the “extreme conditions” described above and try to determine what is causing the amplifier to overheat. Refer to “Thermal Considerations” on page 16 or to the “Troubleshooting” section in Appendix A for more help. The rear panel of the M-Series amplifiers is comprised of the fans, the input and output connectors, and a number of cool extra features. You may ask, “Why don’t the fans just go fast all the time?” Well, if it did, you might actually hear it whirring during your quiet moments (there are quiet moments in your life, aren’t there?). While this whirring would be of no concern in most live-sound situations, it could become annoying in a control room environment. So, when the M-Series amplifier is not working hard, the fans are off (or they go slow); when the music gets loud and puts the amp to work, the fans go fast. 6. POWER Switch To make the amp operate, push the top half of the POWER switch. It clicks into place and the light in the switch illuminates. To turn the amp off, push the lower half. It’ll click again and the light will extinguish. When you power up the M-Series amplifier, a built-in delay circuit prevents any pops or thumps from being transmitted to the speakers due to turn-on instability in the system. Be sure the signal driving the amplifier is turned down when you first power up the system. There are few things as rude as 3 seconds of silence followed by 250 watts of full-blast stereo sound! (Well, maybe 250 watts of accordian music...) If you shut down your system, turn off your amplifiers first. When powering up, turn on your amplifiers last. This way, equipment feeding the amp won’t “pop” or “thud” when it’s powered up or down. 7. SPEAKER OUTPUTS There are two methods for connecting your speakers to the M-Series amplifier, binding posts and Speakon® connectors. To use the binding post outputs, you can terminate your speaker cables with single or double banana plugs, spade lugs, or leave them unterminated with bare wire. Unscrew the amp’s binding posts enough to reveal the holes on their sides, then insert your stripped wires (stripped about 3/8" back) into the holes and retighten the posts (finger tight is fine — please don’t reef on them with a wrench!). Be careful that no runaway strands touch the chassis or other terminals. The red posts are labeled “+,” which means positive. The black posts are labeled “–” for negative. You probably know the importance of getting these terms correct — if one side is hooked up “in phase” and the other side is “out of phase,” you’ll be “out of work.” (By the way, although everyone says “phase” in this situation, the correct word is “polarity”... but it’s not as much fun to say.) Using high-quality stranded speaker cable (16 gauge or thicker), connect the positive outputs of the amplifier to the positive inputs of your speakers, and the negative outputs to the negative inputs. The exception: If you’re using the amplifier in BRIDGE mode, this does not apply, (see Bridge Mode on page 19). In addition to the binding posts, the M-Series amplifier also has Speakon SPEAKER OUTPUTS. These have the advantage of locking into place, and many professional loudspeakers are equipped with Speakon connectors. There are three Speakon connectors, for channel 1, channel 2, and for a bridged connection.

AMP MODE This three-way switch, along with the X-OVER switches, determines what kind of amplifier you want the M-Series amplifier to be (or not to be — what was the question?). The AMP MODE switch determines the input signal routing within the amplifier. Shipped from the factory, the switch is set to STEREO. This is correct for about 90% of the applications using an amp like this. But you may be in the 10% bracket, requiring special input routing within the amp. The AMP MODE should be configured before operation — if you must change it during performance, turn down the Gain controls as a precaution to protect the speakers from any inadvertent pops or thumps. STEREO mode (separate left and right inputs, separate left and right outputs) is the typical setup for amplifying stereo signals. MONO mode (sometimes called Dual-Mono – one mono input, two mono outputs) is for sending a mono signal to two different speaker sets, with separatelyadjustable Gain controls. BRIDGE mode (sometimes called Bridged-Mono – one mono input, one mono output) uses both sides of the amp to double the power to one speaker set. With two M-Series power amplifiers, each set to BRIDGE mode, you can deliver as much as 4000 watts per amplifier for the M•4000 (2000 watts for the M•2000 and 3000 watts for the M•3000). If you set the AMP MODE switch to MONO or BRIDGE, normally you would use just the Channel 1 input. You can connect a stereo input to Channels 1 and 2, but the M-Series amplifier sums the two inputs and delivers a mono signal to the amplifier stage. + The M-Series amplifier expects to see a nominal signal level anywhere between the –10dBV “semipro” and +4 dBu “pro” standards, meaning almost any line-level mixer or other device can be plugged into the amp’s INPUTs. Use the Gain controls to adjust the gain of the amplifier to match the signal level you’re using. 10. Thru Connectors Someday you’ll do a show and realize that one M-Series amplifier is just not going to do the job — you’ll need a six-foot-high rack full of ’em. That’s what the Thru jack is for. Simply plug the signal source outputs into the first amp’s INPUTs, patch from that amp’s Thru jacks to the next amp’s INPUTs, and so on, daisy-chaining as many amps as you can afford (assuming your console has low-impedance outputs). A general rule of thumb is to maintain a load impedance 10 times or more than the source impedance to prevent excessive loading. If your console has an output impedance of 100 ohms, then you can daisy-chain up to twenty-four M-Series amplifiers, which presents a load of 1000 ohms to the console (input impedance of 24 kohms divided by 24 amplifiers = 1000 ohms). The Thru jacks can also be used to relay the signal on to other devices such as a DAT or cassette recorder, enabling you to record exactly what the audience is hear- CHANNEL 1 GND BRIDGE + + PIN 1 = CH1 PIN 2 = CH2 CHANNEL 2 GND HIGH EFFICIENCY POWER AMPLIFIER AMP MODE SERIAL / DATE CODE STEREO MONO 1300W / CH 4Ω LOAD MIN 2600W BRIDGE 8Ω LOAD MIN 1 The M-Series amplifiers give you a choice — it has combination XLR and 1/4" inputs, as well as screw terminal balanced input connectors. Sonically (and electrically) they’re identical. Since these inputs are all in parallel (the Thru jacks are in parallel with the inputs as well), you shouldn’t connect more than one source to the INPUT connectors. Each can be used with either balanced or unbalanced signals. See “Input Wiring” on page 17 for more information about making the input connections.

Owner’s Manual 13 ~ nal inputs, you could jumper the signal over from Channel 1 to Channel 2 as shown below. JUMPERS CHANNEL 1 You can use the Thru jack as an input, if necessary, since it’s wired in parallel with the other input connectors. You can also use the 1/4" TRS INPUT jacks as Thru jacks. Simply connect the 1/4" TRS INPUT jacks on the first amplifier to the TRS 1/4" INPUT jacks on the second amplifier using 3-conductor shielded cables with TRS plugs on both ends. Warning: If you use a regular guitar cord with 2conductor TS plugs, you’ll unbalance the signal at the screw terminal input by grounding the low side (–) of the signal (pin 3). GND CHANNEL 1 For normal operation, leave the switch in the FULL position. This allows full-range operation for that channel (no crossover filter). With the switch in the LPF (low-pass filter) position, all the frequencies below 150 Hz are allowed through the channel, and all the frequencies above 150 Hz are rolled off with a 2nd-order Butterworth filter. Set the AMP MODE switch to STEREO. Note: You cannot use the AMP MODE switch set to MONO to accomplish this because the X-OVER switches are located before the AMP MODE switch in the signal path. 3. Set the X-OVER switch on Channel 1 to LPF and the X-OVER switch on Channel 2 to HPF. 4. Connect the Speaker Output for Channel 1 to the woofer or subwoofer speaker cabinet. 5. Connect the Speaker Output for Channel 2 to the full-range or mid/high speaker cabinet. With the switch in the HPF (high-pass filter) position, all the frequencies above 150 Hz are allowed through the channel, and all the frequencies below 150 Hz are rolled off with a 2nd-order Butterworth filter.

You could also use the X-OVER switch as a high-pass filter for both channels. For example, in a monitor system, many monitor speakers don’t reproduce frequencies below 100 Hz or 150 Hz.

Power Receptacle If you’re working at quiet levels all the time, or you’ve already placed a compressor/limiter in the signal path, or if you just hate compression, you can leave the LIMITER out of the circuit (OFF). This is a standard 3-prong IEC power connector. Connect the detachable linecord (included in the box with your M-Series amplifier) to the power receptacle, and plug the other end of the linecord into an AC outlet properly configured with the correct voltage for your particular model. The LIMITER works independently on each channel. It senses when the amplifier channel is about to be overdriven and attenuates the overall level just enough to keep the signal from clipping. Clipping occurs when the output voltage no longer linearly follows the input voltage and simply stops. This causes a sine wave to “square off,” and the average power going into the speaker is roughly double that of a sine wave. Square waves sound awful, and could possibly damage your speakers and/or your reputation. The LIMITER is especially handy when you’re working with loud output levels. Having the signal spikes (kick drum, for instance) attenuated a bit can actually increase the apparent loudness of the overall mix without diminishing the “power” behind the spikes. Also, if you are driving the amplifier quite hard in an adverse environment (high heat) and under heavy loading, turning on the LIMITER will help to prevent the amplifier from going into “OVER TEMP” protection. This is much more preferable to lightening the load on the amplifier by reducing the number of speakers connected. Be Forewarned: With the LIMITER engaged, you can still overdrive the amplifier into clipping and cause distortion. It just takes a stronger signal to do it. So even with the LIMITER turned on, you should still pay attention to the OL LEDs. 13. AC LINE BREAKER This is a resettable circuit breaker that monitors the amount of current being drawn by the amplifier. Under normal operating conditions, this should never pop. An unusual condition may cause the breaker to pop, such as a mains voltage surge occurring at the same time as a peak amplifier output. Turn the POWER switch off, and push the BREAKER button to reset the circuit breaker. Turn the POWER switch back on and the amplifier should resume normal operation. If the circuit breaker pops again, something probably isn’t right. • Make sure the total impedance of the speakers connected to the outputs is 2 ohms or greater (per channel) in stereo mode, or 4 ohms or greater in bridged mode. • If the breaker pops right away, even with the Gain controls turned down and the speakers disconnected, there may be something wrong inside the amplifier. Refer to “Appendix A: Service Info.” The power cord that comes packed with your amplifier may look like the same one that plugs into your mixer or computer, but it’s not! An IEC power cord that you find on a typical product will likely have tiny 18 gauge wire inside. The power cord that comes with our amplifier has 14 gauge wire inside, 250% larger than that of an 18 gauge cord. If you use one of these lighter gauge cords on your amplifier it may, quite literally, melt! So don’t lose that power cord, but if you do, contact Mackie for a replacement. Owner’s Manual even notice any audible difference. We recommend that you leave it engaged, hence the TYPICAL label above it. For current-delivery purposes, the amplifier’s voltage source (wall outlet, extension cords, or power strips) must be capable of continuously delivering the following AC current (for 120V version): M•2000 9 amps M•3000 12 amps M•4000 15 amps And for safety reasons, that source must be a “3-prong” outlet with hot, neutral, and ground terminals. We’re dealing with some big-time electricity here — don’t mess with it. See “AC Power Considerations” on page 16 for more details. 15. Fans There are two fans, one for each amplifier channel. They pull air in from the rear, move it through the constant thermal gradient heatsinks, and exhaust the warm air through the front. When the amplifier is first turned on, the fans are off. They remain off until the inside of the amplifier warms to 50º C (122º F). The fans start up at a slow speed until the inside of the amplifier warms to 65º C (149º F), when they kick into high speed. In a live sound application, the sound of the fans is usually not a problem. But in a control room or quiet listening situation, it may be of a concern. When the amplifier is idling or operating at a low power, the fans are off so you don’t hear the constant whirring of the fans. At moderate power levels, the fans turn on at a slow speed, so they probably still won’t be audible above the program that you are listening to. At high power levels, the fans may kick into high speed, but the high volume level will certainly cover the sound of the fans. It is important to leave space in front of and behind the amplifier so the air can flow freely. See “Thermal Considerations” on page 16 for more information. Owner’s Manual 15 M-Series General Precautions and Considerations Rack Mounting AC Power Considerations The M-Series amplifiers require two rack space units (2 IU = 3.5"). The M•2000 requires 17.0" depth inside the rack, including the rear supports. The M•3000 and M•4000 require 19.5" depth inside the rack, including the rear supports. When designing your rack, put the heavier items at the bottom and the lighter items toward the top. Be sure the amplifier is plugged into an outlet that is able to supply the correct voltage specified for your model. Secure the front panel of the amplifier to the front of the rack using four screws with soft washers to prevent scratching the panel. In addition, because of the weight of the amplifier, you must secure the rear support brackets of the amplifier to the back of the rack. You could use a support rail or shelf across the back of the rack, or angle brackets attached between the rear support brackets and the rear rails of the rack. This is recommended for all components mounted in a rack that is going to be moved frequently (or thrown in the back of a pickup truck and transported down a bumpy gravel road to that outdoor festival!). Thermal Considerations The M-Series amplifier is fan-cooled and brings air in through the rear and out through the front. Make sure that cool air is available at the rear of the amplifier, and that there is room at the front for the warm air to exit from the amplifier and dissipate. If rack-mounted, make sure the amplifier is not pulling warm (or hot) air in from the rack. The M-Series amplifier’s unique Constant Thermal Gradient heatsinks provide substantially better cooling for the output transistors than conventional designs that simply blow air through the chassis, getting dust and other contaminants over all the internal components. The heatsinks contain a cooling tunnel that provides a shorter, more directed path for the air, with the air moving faster toward the end of the tunnel to balance the temperature along the entire length of the heatsink. This results in increased reliability and longevity for the amplifier because the output transistors are kept cooler. 16 M-Series If the line voltage should drop below about 97% of the rated voltage, the amplifier will no longer be able to supply rated power. (It will continue to operate down to 65% of the rated line voltage, but it just won’t be able to reach full rated power.) Be sure the AC outlet can supply enough current to allow full power operation of all the amplifiers plugged into it. The outlet should be a socket that matches the power cord. WARNING: Bypassing the plug’s ground pin can be dangerous. Don’t do it! The AC current demand of an amplifier varies depending on several factors, including the crest factor and the duty cycle of the program material. Under typical conditions reproducing rock music where musical peaks are just below clipping, the M-Series amplifiers require the following average currents: M•2000 Amplifier Loading Average Current Required 2 ohms per side or 4 ohms bridged 4 ohms per side or 8 ohms bridged 8 ohms per side or 16 ohms bridged 120V 8.6A 5.6A 3.7A 240V 4.3A 2.8A 1.9A 120V 11.1A 7.4A 4.8A 240V 5.6A 3.7A 2.4A 120V 14.2A 9.3A 6.0A 240V 7.1A 4.7A 3.0A M•3000 Amplifier Loading 2 ohms per side or 4 ohms bridged 4 ohms per side or 8 ohms bridged 8 ohms per side or 16 ohms bridged M•4000 Amplifier Loading 2 ohms per side or 4 ohms bridged 4 ohms per side or 8 ohms bridged 8 ohms per side or 16 ohms bridged Under typical conditions, reproducing rock music where musical peaks are just below the clipping point, you can safely connect one or more amplifiers to an AC service. Use the table below as a guideline: Maximum Number of Amplifiers on a 120V/15A Service M•2000 Amplifier Loading (or 240V/7.5A Service) 2 ohms per side or 4 ohms bridged 4 ohms per side or 8 ohms bridged 8 ohms per side or 16 ohms bridged 2 3 4 M•3000 Amplifier Loading 2 ohms per side or 4 ohms bridged 4 ohms per side or 8 ohms bridged 8 ohms per side or 16 ohms bridged 1 2 3 M•4000 Amplifier Loading 2 ohms per side or 4 ohms bridged 4 ohms per side or 8 ohms bridged 8 ohms per side or 16 ohms bridged 1 1 2 The M-Series amplifiers are equipped with an in-rush limiting circuit to minimize startup current and prevent tripping the breakers when two or more amplifiers are turned on at the same time, on the same breaker. Sequencing is not required. If you use an extension cord to supply power to the “amp rack,” it should have a third wire safety ground to avoid presenting a safety hazard. We also recommend using a cord that has conductors large enough to avoid severely limiting the amplifier’s ability to supply high currents on transients. Power amplifiers can have momentary peak current requirements many times above the nominal average current draw. According to Ohm’s Law, the greater the resistance of the linecord, the more input power is lost between the AC outlet and the power amplifier (across the linecord). And to further aggravate the matter, this relationship is nonlinear. The amount of power lost across the linecord increases exponentially as the current demand increases. So if the current demand doubles momentarily because of an exceptionally loud bass note, the amount of AC input power lost across the linecord increases four times. You can see that it is very important to keep the resistance of the linecord to a minimum. That’s why we recommend using a heavy gauge extension cord (like 14 gauge or bigger). Remember, wire gets thicker as the gauge number gets smaller (10 gauge is thicker than 14 gauge). AC Power Distribution In order to minimize ground loops, the safety grounds for all the outlets should be connected to a common (“star”) grounding point, and the distance between the outlets and the common grounding point should be as short as possible. If lighting is used in a show, it is preferable to power the lights from a different AC circuit than the one powering the audio equipment. This will help minimize noise from the lights coupling into the audio (particularly if SCRs are used). Owner’s Manual It is recommended that a stiff supply of AC power be used because the amplifier places high current demands on the AC line. The more power that is available on the line, the louder the amplifier will play and the more peak output power will be available for cleaner, punchier bass. Input Wiring Use a high-quality 3-conductor shielded cable to connect the signal between the signal source (mixing console, equalizer, etc.) and the balanced inputs to the amplifier. If you’re making an unbalanced connection, use a high-quality 2-conductor shielded cable. Your Mackie Dealer can recommend a suitable cable for your application. Refer to “Inputs” [9] on page 13 for more information about making the input connections.

Troubleshooting No Power • Our favorite question: Is it plugged in? Make sure the AC outlet is live (check with a tester or lamp). • Our next favorite question: Is the POWER [6] switch on? If not, try turning it on. • • Is the light in the power switch illuminated? If not, make sure the AC outlet is live. If so, refer to “No Sound” below. The AC line breaker on the rear panel has popped. To reset the breaker, turn the power switch off, push in the button on the breaker, and turn the power switch back on. One side is way louder than the other! • Do the amplifier’s meters [2] read the same on both sides? If not, your source signal may be delivering an out-of-balance stereo signal. • Are both Gain [1] knobs set to the same position? • Are the speaker(s) impedances matched? • Try swapping sides: Turn off the amp, swap the speaker cables at the amp, turn the amp back on. If the same side is still louder, the problem is with your speakers or speaker cabling. If the other side is louder now, the problem is with the mixer, the amp, or the line-level cabling. If the breaker pops again, disconnect the speakers from the amplifier and repeat the above procedure. If the breaker pops again, there may be a problem with the amplifier. Refer to “Repair” on the next page to find out how to proceed. No sound! Owner’s Manual Appendix A: Service Information The stereo music sounds kind of sideways, and the bass frequencies diminish when standing center, but get louder as you approach one side! • Are the Gain [1] controls turned all the way down? Slowly turn them up and see if you hear anything. • Is the signal source turned up? Make sure the signal level from the mixing console (or whatever device immediately precedes the amplifier) is high enough to produce sound in the amplifier. The SIG LEDs [2] should be blinking to indicate that signal is present. As soon as the music gets loud, the amp shuts down! • Check the amplifier’s meters [2]. Be sure that OL is not lighting up frequently or continuously. • If the speakers are wired for BRIDGE mode, make sure the AMP MODE [8] switch is set to BRIDGE. • • Is the X-OVER [11] switch set to LPF? If so, you are only getting the lowest frequencies (below 150 Hz) through the speakers. Set the X-OVER switch to the FULL position to verify sound is present. Can the amp breathe? The M-Series amplifier draws its ventilation air in from the rear and out through the front. It needs plenty of fresh air to stay cool. Do not block the ventilation ports. • Is the SHORT [4] LED lit? If so, you’ve got a dead short somewhere in your speaker setup, or the total impedance of the load is too low. Turn the amp off and rectify that right away. Owner’s Manual • Check the polarity of the speaker cable connections. You may have your positive and negative connections reversed at one end of one speaker cable. 21 M-Series It hurts when I touch my arm, or my leg, or even my head! Repair • Service for Mackie products is available at a factoryauthorized service center. Service for Mackie products living outside the United States can be obtained through local dealers or distributors. You have a broken finger. Bad sound! • • • Is it loud and distorted? Turn down the signal coming from the mixer or signal source. Is the input connector plugged completely into the jack? Check the speaker connections and verify that all connections are tight and that there are no stray strands of wire shorting across the speaker terminals. 1. Review the preceding troubleshooting suggestions. Please. 2. Call Tech Support at 1-800-898-3211, 7 am to 5 pm PST, to explain the problem and obtain a Service Request Number. Have your serial number ready. You must have a Service Request Number before you can obtain warranty service. 3. Keep this owner’s manual and the detachable linecord. We don’t need them to repair the amplifier. 4. Make sure the signal cable is not routed near AC cables, power transformers, or other EMI-inducing device. Pack the amplifier in its original package, including endcaps and box. This is VERY IMPORTANT. Mackie is not responsible for any damage that occurs due to non-factory packaging. 5. Is there a light dimmer or other SCR-based device on the same AC circuit as the amplifier? Use an AC line filter or plug the amplifier into a different AC circuit. Include a legible note stating your name, shipping address (no P.O. boxes), daytime phone number, Service Request Number, and a detailed description of the problem, including how to duplicate it. 6. If possible, listen to the signal source with headphones plugged into the console. If it sounds noisy there, the problem’s not in the amplifier. Write the Service Request Number in BIG PRINT on top of the box. Units sent without the Service Request Number will be refused. 7. Tech Support will tell you where to ship the amplifier for repair. We suggest insurance for all forms of cartage. 8. You will need to contact the authorized service center for their latest turn-around times. The amplifier must be packaged in its original packing box, and must have the Service Request Number on the box. Once it’s repaired, the authorized service center will ship it back, pre-paid (if it was a warranty repair). If possible, listen to the signal source with headphones plugged into the console. If it sounds bad there, the problem’s not in the amplifier. Noise/Hum • • • • If your M-Series amplifier needs service, follow these instructions: Check the signal cable between the mixer and the amplifier. Make sure all connections are good and sound. For additional up-to-date information please visit our website at www.mackie.com. Note: Under the terms of the warranty, you must ship or drop-off the unit to an authorized service center. The return ground shipment is covered for those units deemed by us to be under warranty.
