TM FAST RECOVERY SERIES HIGH CURRENT POWER AMPLIFIERS The world is full of amplifiers that do one thing – amplify audio signals. But at Mackie Designs, we’ve always put out the extra effort to provide more quality and more features than our competitors while maintaining a comparable (or lower) price. The FR Series™ power amplifiers are designed to perform reliably under the most adverse conditions, and we’ve added a bundle of extra features, so you don’t have to put out the extra bucks to buy a bunch of add-ons or plug-ins to make your sound system do what you want it to do. Meticulous Detail Perhaps the most important aspect of the FR Series amplifiers is the attention to detail in the design of the electronic architecture. We have incorporated a number of unique properties including Fast Recovery, sustained high-current output capability, high voltage and current slew rate, and defeatable clipping eliminator, to ensure that the output of the amplifier is virtually distortion-free.

Fast Recovery refers to the amplifier’s ability to recover after being over-driven into clipping. Most amplifiers’ output circuits tend to stay “latched” in the clipping mode, making their recovery time relatively slow, especially at high frequencies. Our FR Series amplifiers incorporate two unique circuit designs that completely eliminate the latching phenomena. The first is a Baker Clamp diode configuration, and the second is the use of two additional supplies that are at a higher voltage than the main supplies. Without getting too technical, the result is no latching and instant recovery from overdrive. Durability. A word Mackie lives by. Mackie mixers are wellknown for their ability to withstand the abuses of the road. Most of Mackie Designs’ employees have experience as musicians, roadies, or sound engineers in the real world of music entertainment and live sound reinforcement. We know what kind of 2 punishment sound equipment can be subjected to, and our engineers know how to design equipment that can take it. Pro features even amateurs can understand. Mackie’s FR Series power amplifiers were designed with professionals – and amateurs – in mind. These amplifiers are great for live sound reinforcement applications as well as studio or broadcast control rooms. With the ability to deliver massive amounts of current instantly, the FR Series amplifiers can handle powersucking subwoofers, yet remain discriminating and responsive when driving a bank of delicate tweeters. Power Output. The M•1200 is rated at 225 watts per channel into 8Ω, 400 watts per channel into 4Ω and 600 watts per channel into 2Ω. In bridge mode the M•1200 is rated at 800 watts into 8Ω and 1200 watts into 4Ω. The M•1400 is rated at 250 watts per channel into 8Ω, 425 watts per channel into 4Ω and 630 watts per channel into 2Ω. In bridge mode the M•1400 is rated at 850 watts into 8Ω, and 1260 watts into 4Ω. Sustained ultra-low impedance capability. The FR Series power amplifiers are designed to drive low impedance loads effortlessly and reliably. Most power amplifiers have difficulty driving anything lower than 4 ohms, but the FR Series power amplifiers can easily drive 2 ohm loads all day long without breaking a sweat. This is a result of the careful and efficient design of the heatsink and cooling tunnels, which keep the output devices running as cool as possible, along with the virtual elimination of VI limiters, which can cause lesser amplifiers to distort or to shut down completely when driving low impedance loads. Inputs, Input Level Controls and Metering. The FR Series amplifiers are equipped with balanced, line-level input connectors for each channel in the form of XLR female jacks and 1/4" TRS phone jacks. In addition, XLR male jacks are provided as thru connections for daisychaining the input signal to multiple amplifiers. The XLR male thru jack is in parallel with the XLR female jack and the 1/4" TRS jack, and any one can be used as an input or thru connector. Each channel has an independent gain control with 40 detents for accurately setting and matching the gain between channels. The gain controls are calibrated in dB (from off to 30) and in volts (with indications of 1V, 2V, and 3V). Six discrete LEDs are used to indicate signal level for each channel, including a signal present LED, indicators at –20, –9, –6, and –3dB below full power, and an overload LED to indicate when the output has reached the clipping point. Outputs. The M•1200 and M•1400 differ in their output connector configurations. They both come with heavy-duty 5-way binding posts, which can accept standard double banana plugs, spade lugs, or bare wire (Export versions will not accept banana plugs due to European safety requirements). The M•1200 also has 1/4" TS phone jack outputs in parallel with the binding posts. The M•1400 comes with Neutrik brand Speakon® connectors in parallel with the binding posts. Stereo, Mono and Bridge modes. The amplifiers can be operated in one of three modes. In stereo mode, the amplifier operates with two inputs and two outputs. It accepts separate channel 1 and 2 input signals, and outputs separate channel 1 and 2 signals. In mono mode, the ampli- so it doesn’t degrade the audio signal in any way.

Some speaker manufacturers provide external processors with plug-in modules for each of the various combinations of horns and drivers (at an additional cost to you!) to compensate the CD horns. Each channel of an FR Series power amplifier has its own built-in CD horn compensation circuit. All you need to do is set the variablefrequency horn EQ control on the amplifier to the manufacturer’s recommended mass breakpoint frequency (the point where the frequency response begins to roll off). As an added feature, if you’re not using CD horns, set the frequency control fully clockwise to the AIR setting to enjoy Mackie’s exclusive AIR EQ, a gentle high-frequency boost that brightens and lightens the sound. Low-cut filter. Virtually all loudspeakers have a low-frequency cutoff point somewhere above 20Hz. Many low-frequency drivers have a –3dB point at 35Hz to 40Hz, while many stage monitor speakers cut off at about 100Hz; there’s no sense in amplifying low- frequency signals that the loudspeaker cannot reproduce. Each channel of the FR Series amplifiers has a continuously variable low-cut filter. Simply dial in the frequency at which the loudspeakers drop off (anywhere from OFF to 170Hz), and reap the benefits of saving amplifier power with cleaner, tighter bass. Built-in subsonic stabilizer. Even with the low-cut filter set to the OFF position, each channel of the FR Series amplifiers has a built-in subsonic stabilizer (technically called infrasonic stabilizer). This dampens the very low frequencies, which can be caused by microphone handling or stage rumble. These frequencies are below the threshold of human hearing, and rob the amplifier of power and contribute to intermodulation distortion. Protection circuits. Both amplifiers are equipped with a number of unique and innovative protection circuits to ensure the safety of your speakers and the amplifiers. Separate left and right Protect LEDs on the front panel indicate when a protection circuit has been activated. For example, when the amplifier is first turned on the outputs are muted for three seconds, during which time the Protect LEDs are lit. This allows time for all the equipment in the system to power up and stabilize, and prevents potentially damaging thumps or pops from propagating to the speakers. Separate left and right Short LEDs indicate if there is a short circuit at the speaker output terminals. This lets you know at a glance to check the speaker wiring for shorts (or recalculate the speaker load impedance) right from the get-go, so you don’t waste precious time searching for the problem. Combined left and right Cold and Hot LEDs indicate if the amplifier has overheated. Under normal operation, the Cold LED remains lit. If the Hot LED should light, the outputs become muted until the amplifier cools to a safe operating temperature, then normal operation ensues. The FR Series: The most affordable, full-featured power amplifiers available. As you can see, there is every reason the M•1200 and M•1400 are fast becoming the premier affordable choice for many sound reinforcement and recording applications. With their proven durability, professional features and specs, and certainly not least, low cost – the FR Series is destined to be a classic. There are no other power amplifiers in their class with all these features at such an affordable price. And that’s why people from all professions, with all kinds of different applications, prefer Mackie’s FR Series. You’ll like them because of their low price, easy-to-use features, and rugged construction. That’s got to sound good. And, of course, Mackie does. 5 SPECIFICATIONS Continuous Average Output Power, both channels driven: M•1200 225 watts per channel into 8 ohms from 20Hz to 20kHz, with no more than 0.025% THD 400 watts per channel into 4 ohms from 20Hz to 20kHz, with no more than 0.050% THD 600 watts per channel into 2 ohms from 20Hz to 20kHz, with no more than 0.095% THD Bridged mono operation: 800 watts into 8 ohms from 20Hz to 20kHz, with no more than 0.05% THD 1200 watts into 4 ohms from 20Hz to 20kHz, with no more than 0.095% THD Maximum Power at 1% THD (per IHF-A-202): 250 watts per channel into 8Ω 425 watts per channel into 4Ω 640 watts per channel into 2Ω 850 watts into 8Ω bridged 1280 watts into 4Ω bridged M•1400 250 watts per channel into 8 ohms from 20Hz to 20kHz, with no more than 0.012% THD 425 watts per channel into 4 ohms from 20Hz to 20kHz, with no more than 0.025% THD 630 watts per channel into 2 ohms from 20Hz to 20kHz, with no more than 0.050% THD Bridged mono operation: 850 watts into 8 ohms from 20Hz to 20kHz, with no more than 0.025% THD 1260 watts into 4 ohms from 20Hz to 20kHz, with no more than 0.050% THD Maximum Power at 1% THD (per IHF-A-202): 280 watts per channel into 8Ω 480 watts per channel into 4Ω 700 watts per channel into 2Ω 960 watts into 8Ω bridged 1400 watts into 4Ω bridged Note: Power ratings are specified at 120VAC (U.S. and Canada) and 240VAC (Export) line voltages.
