Welcome to Samson AirLine—the wireless system for the new millenium! Wireless microphone and instrument systems wereoriginally developed to eliminate cables, providing unparalleled freedom of movement. AirLine takes this concept to a new level withtransmitters so small, lightweight and aerodynamic, they are nearly invisible, providing a completely “hassle-free” user experience.To create the world’s smallest wireless transmitters, we developed new proprietary technology. Featuring miniaturized circuitry and theability to operate on a single tiny AAA battery (with 14 hours typical battery life), these transmitters also feature significantly improvedwireless reception and sound quality. What’s more, the AR1 micro receiver developed for the AirLine systems is actually smaller thanthe typical wireless transmitter.There are five different Samson AirLine systems detailed in this manual. All operate in the 801 - 805 MHz UHF frequency range andall contain either an AR1 micro receiver or a UR1 true diversity receiver (from our acclaimed Series One system). The AirLine UHFMicrophone System contains an AX1 hand-held transmitter, which plugs into any standard wired dynamic microphone. The AirLineUHF Presentation System contains an AL1 transmitter, which contains a built-in electret condenser microphone and connection for anoptional lavalier microphone. The AirLine UHF Performance System combines a feather-light AH1 headset transmitter with a SamsonQV headset microphone, while the AirLine UHF Fitness System combines the AH1 with a Samson QE headset microphone. Finally,the AirLine UHF Wind Instrument System combines the AH1 with an Audio-Technica Pro 35X horn microphone.In this manual, you’ll find a more detailed description of the features of all AirLine systems, as well as a guided tour through allcomponents, step-by-step instructions for setting up your system and full specifications. If your AirLine system was purchased in theUnited States, you’ll also find a warranty card enclosed—don’t forget to fill it out and mail it!

If you’ve had some prior experience using wireless systems, these QuickStart instructions will get you up and running with yourAirLine system in a matter of minutes! Detailed instructions for setting up and using your AirLine system can be found on page 14 ofthis manual, and the “Guided Tour” sections on pages 4 - 13 provide full descriptions of all AirLine component controls and displays.1. Make sure that the supplied AR1 receiver and AX1, AL1 or AH1 transmitter are factory preset to the same channel.2. Physically place the AR1 where it will be used (if desired, it can be wall-mounted using the supplied holder) and extend its antennavertically.3. Set the power switch to your transmitter to the “off” position (away from the arrow) and place a fresh battery in it. Then turn thetransmitter back on momentarily; its LED will flash once and then go off if the battery is sufficiently strong. Once battery strength isverified, turn the transmitter off.4. If you are using an AX1, plug its XLR connector into a wired dynamic microphone; make a good tight connection, using thesupplied rubber gasket if necessary. If you are using the AL1 with an external lavalier microphone, make the physical connectionbetween its input connector and the microphone.5. Turn the Volume knob on the AR1 completely counterclockwise. Connect the supplied AC adapter to the AR1 receiver and plug itin, but leave its power off for the moment.6. Turn your audio system off and make the physical cable connection between the AR1 balanced or unbalanced output jack(if necessary, both can be used simultaneously) and a mic level audio input of your amplifier or mixer.7. Turn on the AR1 receiver; its “Power/ RF” LED will light steadily red.2Samson AirLine QuickStartENGLISH
8. Turn on your transmitter. The “Power/ RF” LED on the AR1 should change color from red to green, indicating that it is receivingvalid RF signal and is placed and positioned correctly.9. Turn on your connected amplifier and/or mixer but keep its volume all the way down. If you are using an AL1 or AH1 transmitter,make sure that it is unmuted. Set the Volume knob on the AR1 fully clockwise; this is unity gain. If you are using an AL1 transmitterwith the built-in microphone, correct placement is critical to sound quality. It should be unobstructed by clothing and either clippedto a shirt pocket or lapel, or worn around the neck on the supplied lanyard.10. Speak or sing into your mic at a normal performance level while slowly raising the audio input control of your amplifier or mixeruntil the desired level is reached. If necessary, use the supplied plastic screwdriver to adjust the transmitter’s Gain trimpot in order toincrease or decrease its signal level.11. Do a walkaround through the intended area of coverage while observing the AR1’s “Power/RF”LED; it should be lit steadily greenin all areas of coverage. Reposition it (or its antenna) as necessary. If extended range coverage is required, a Samson UR1 truediversity receiver (set to the same channel) can be substituted.12. If you hear any spurious noise from the AR1 output when the transmitter is turned off, use the supplied plastic screwdriver toadjust the AR1 Mute (squelch) level control, slowly turning it clockwise until the point at which the noise disappears.3Samson AirLineQuickStartENGLISH
1: Antenna - This swivel mounting allows full rotation foroptimum placement of the antenna. In normal operation,the antenna should be placed in a vertical position. It canbe folded inward for convenience when transporting theAR1. See the “Setting Up and Using Your AirLine System”section on page 14 in this manual for more informationabout antenna positioning.2: Power On / RF LED - This lights red whenever the AR1 ispowered on and green whenever the AR1 is receiving RFsignal from a transmitter.3: Peak LED - This LED lights red when output signal fromthe AR1 is at the onset of clipping (that is, when it is on theverge of being distorted). If you see this light duringoperation, move the microphone further away or lower thevolume level of your instrument or transmitter. For moreinformation, see the section entitled “Setting Up and UsingYour AirLine System” on page 14 in this manual.4: Power switch - Move this switch in the direction of thearrow to turn power to the AR1 on; move it away from thearrow to turn power off.5: Volume control - This knob sets the level of the audiosignal being output through both the AR1 balanced andunbalanced output jacks (see #6 and #7 on the followingpage). Reference level is obtained when the knob is turnedfully clockwise.4Samson AirLine Guided Tour - AR1 ReceiverENGLISH
6: Unbalanced output* - Use this unbalanced high impedance(5 - 10 K Ohm) 1/4" jack when connecting the AR1 to consumer(-10) audio equipment. Wiring is as follows: tip hot, sleeve ground.7: Balanced output* - Use this electronically balanced lowimpedance (600 - 2500 Ohm) XLR jack when connecting the AR1to professional (+4) audio equipment. Pin wiring is as follows:Pin 1 ground, Pin 2 high (hot), and Pin 3 low (cold).8: Mute (squelch) control -This control determines themaximum range of the AR1before audio signal dropout.Although it can be adjustedusing the supplied plasticscrewdriver, it shouldnormally be left at its factory setting. See the “Setting Up and Using Your AirLine System”section on page 14 in this manual for more information.9: DC input - Connect the supplied 12 volt 200 mA power adapter here.WARNING: Do not substitute any other kind of power adapter; doing so can causesevere damage to the AR1 and will void your warranty.As shown in the illustration on the left, the supplied AR1 receiver holder can be used towall-mount the AR1 in fixed installations.* If required, both the balanced and unbalanced outputs can be used simultaneously.5Samson AirLineGuided Tour - AR1 ReceiverWall-mount AR1 receiver holderENGLISH

Although rechargeable Ni-Cadbatteries can be used, they do not supply adequate current for more thanfour hours. WARNING: Do not insert the battery backwards; doing so cancause severe damage to the AX1 and will void your warranty.6: Microphone Input Level control (trimpot) - Use the supplied plasticscrewdriver to raise or lower the input level sensitivity of the AX1 as required.See the “Setting Up and Using Your AirLine System” section on page 14 inthis manual for more information.7Samson AirLineGuided Tour - AX1 Handheld Transmitter +_AF LEVELMINMAXENGLISH
1: Power / Battery LED - This LED flashes once when the AL1 is first turned on and lightssteadily red when there is less than 2 hours of battery power remaining, indicating that thebattery needs to be changed.2: Antenna - This permanently attached flexible antenna should be fully extended duringnormal operations. See the “Setting Up and Using Your AirLine System” section on page 14in this manual for more information about antenna positioning.3: Electret condenser microphone - This high- quality unidirectional electret condensermicrophone with metal windscreen is optimized for clear, crisp reproduction of speech.It is active whenever the AL1 is powered on, as long as there is no connection made to thelavalier microphone input connector (see #4 below). When a plug is inserted into thelavalier microphone input connector, this built-in microphone is muted.4: Lavalier microphone input connector - Use thisstandard 2.5 mm mini-jack if you want to connectan external lavalier microphone to the AL1.Note that, because the AL1 has a built-in electretcondenser microphone (see #3 above), the use of anexternal lavalier mic is optional and not required.The AL1 provides 2.7V of phantom power, socondenser mics can be used if desired.8Samson AirLine Guided Tour - AL1 Body Pack TransmitterENGLISH
5: Gain control (trimpot) - Use the supplied plastic screwdriver to raise or lower the input level sensitivity of the AL1 as required. Seethe “Setting Up and Using Your AirLine System” section on page 14 in this manual for more information.6: Mute switch - Move this switch in the direction of the arrow to mute the AL1; move it away from the arrow to unmute it andtransmit audio signal.Because the carrier signal remains during muting, no “pop” or “thud” will be heard. Note that turning this offdoes not turn off the transmitter power—it is simply a way to temporarily mute the transmission of audio signal. If you don’t plan onusing the AL1 for extended periods, turn it off power by using the power on-off switch (see #7 below). Be sure to mute the audiosignal at your external mixer or amplifier before turning the AL1 power on or off, or an audible pop may result.7: Power switch - Move this switch in the direction of the arrow to turn power to the AL1 on; move it away from the arrow to turnpower off.

13Samson AirLineGuided Tour - AH1 Headset TransmitterAH1As shown in the illustration above, the correct way to wear yourQV / QE Headset is over the ears, as you would wear a pair ofeyeglasses. Because the QV / QE Headset is specially designed to beused up close, be sure to mount the microphone directly in front ofyour lips. To avoid feedback problems, take care not to cover themic capsule with your hand.IMPORTANT NOTE: As shown in the illustration on the left, the rearband of the headset should be positioned down at the base of theneck, not high up on the back of the head.AH1 transmitter with Samson QV Headset Mic (UHF Performance System) or Samson QE Headset Mic(UHF Fitness System)ENGLISHRight way Wrong way
14Samson AirLineThe basic procedure for setting up and using your AirLine System takes only a few minutes:1. For your AirLine system to work correctly, both the receiver and transmitter must be set to the same channel. Remove all packingmaterials (save them in case of need for future service) and check to make sure that the supplied AR1 receiver and AX1, AL1 or AH1transmitter are set to the same channel (page 71 in this manual presents a complete channel plan). If these channels do not match,contact your distributor or, if purchased in the United States, Samson Technical Support at 1-800-372-6766.2. Physically place the AR1 receiver where it will be used (the general rule of thumb is to maintain “line of sight” between thereceiver and transmitter so that the person using or wearing the transmitter can see the receiver). The supplied wall-mount holderallows the AR1 to be mounted on a wall if desired. Extend the AR1 antenna and place it in a vertical position.3. Make sure the Power on-off switch in your transmitter is set to “Off.”4a. If your system contains an AX1 handheld transmitter, unscrew the bottom section by turning it counterclockwise and then slide itoff.4b. If your system contains an AL1 body pack transmitter, turn it over and slide off the battery door.4c. If your system contains an AH1 headset transmitter, gently pry off the battery cover and slide it upwards and off to open thebattery compartment. Please use care when opening this cover as undue force will destroy the hinge.5. Place a fresh AAA alkaline battery in the transmitter battery compartment, taking care to observe the polarity markings. If you areusing an AX1 handheld transmitter, replace the bottom section by sliding it on and then screwing it back on. If you are using an AL1body pack transmitter, replace the battery door by sliding it in until it clicks. If you are using an AH1 headset transmitter, replace thebattery cover and gently press down on it until it clicks. Whichever transmitter you are using, leave it off for the moment.6. Make the physical cable connection between the AR1 output jack and a mic level audio input of your amplifier or mixer. Thebalanced XLR jack is preferable, since it will deliver an electromagnetically cleaner signal. If required, both the balanced andunbalanced outputs can be used simultaneously. Leave your amplifier (and/or mixer) off at this time.7. Turn the Volume knob on the AR1 completely counterclockwise. Connect the supplied AC adapter to the DC Input on the side ofSetting Up and Using Your AirLine SystemENGLISH
15Samson AirLinethe AR1, then plug the adapter into any standard AC outlet. Slide the Power switch in the direction of the arrow to turn on the AR1;the “Power/ RF” LED will light steadily red.8. Turn on the power to your transmitter (using its Power on-off switch); the “Power/Battery”LED will flash if the battery is sufficientlystrong (if it lights steadily, the battery has less than 2 hours of power remaining and should be replaced). At this point, the“Power/ RF” LED on the AR1 should change color from red to green, indicating that it is receiving valid RF signal and is placed andpositioned correctly.9. Now it’s time to set the audio levels. Turn on your connected amplifier and/or mixer but keep its volume all the way down. If youare using an AL1 or AH1 transmitter, make sure that it is unmuted (its Mute switch should be positioned away from the arrrow). Thenset the Volume knob on the AR1 fully clockwise; this is unity gain. If you are using an AL1 transmitter with the built-in microphone,note that correct placement is critical to sound quality. We recommend that you place it as shown in the illustrations on this page—unobstructed by clothing and either clipped to a shirt pocket or lapel, or worn around the neck on the supplied lanyard.10. Speak or sing into your mic at a normalperformance level while slowly raising the volumeof your amplifier and/or mixer until the desiredlevel is reached. Note that Unidirectionalmicrophones (mics which pick up signal from justone direction) such as the built-in AL1 electretcondenser are less prone to feedback than othertypes of mics. Any feedback problems youencounter can be minimized by being sure not touse the microphone directly in front of a PAspeaker or by using an equalizer to attenuate thosehigh- or mid-range frequencies which are causingthe feedback “squealing”.Setting Up and Using Your AirLine SystemSAMSONSAMSONENGLISH
16Samson AirLine11. If you hear distortion at the desired volume level, first check to see whether the red “Peak” LED on the AR1 is lit. If it is not, makesure that the gain structure of your audio system is correctly set (consult the owners manual of your mixer and/or amplifier for details).If the red “Peak” LED is lit, do the following:•If you are using an AX1 handheld transmitter, use the supplied plastic screwdriver to turn its Microphone Input Level control(trimpot) slowly counterclockwise (towards the “Min” position) until the distortion disappears.•If you are using an AL1 body pack transmitter with its internal electret condenser microphone or an AH1 headset transmitter,simply move the microphone further from your mouth. If you are using an AL1 with an external lavalier microphone, use thesupplied plastic screwdriver to turn the Gain control (trimpot) slowly counterclockwise until the distortion disappears.Note that, following this setup procedure, you can always lower the Volume knob of the AR1 in order to attenuate the output signal ifnecessary.12. Conversely, if you hear a weak, noisy signal at the desired volume level, again make sure that the gain structure of your audiosystem is correctly set (consult the owners manual of your mixer and/or amplifier for details) and that the Volume control of the AR1 isfully clockwise. If it is and the signal coming from the AR1 is still weak and/or noisy, do the following:•If you are using an AX1 handheld transmitter, use the supplied plastic screwdriver to turn its Microphone Input Level control(trimpot) slowly clockwise (towards the “Max” position) until the signal reaches an acceptable level.•If you are using an AL1 body pack transmitter with its internal electret condenser microphone or an AH1 headset transmitter,simply position the microphone closer to your mouth. If you are using an AL1 with an external lavalier microphone, use the sup-plied plastic screwdriver to turn the Gain control (trimpot) slowly clockwise until the signal reaches an acceptable level.Setting Up and Using Your AirLine SystemENGLISH
17Samson AirLine13. Temporarily turn down the level of your mixer/amplifier system and turn off the power to your transmitter, leaving the AR1 on.Then restore the previously set level of your mixer/amplifier. With the transmitter off, the receiver output should be totally silent—if itis, skip ahead to the next step. If it isn’t (that is, if you hear some noise), you may need to adjust the AR1 Mute (squelch) control.When the Mute control is at its minimum setting, the AirLine system always provides maximum range without dropout; however,depending upon the particular environment your system is used in, you may need to reduce that range somewhat in order to eliminateband noise when the transmitter is turned off. To do so, use the provided screwdriver to rotate the Mute control completelycounterclockwise (to the “Min” position), then slowly turn it clockwise until the noise disappears. If no noise is present at anyposition, leave it at its fully counterclockwise “Min” position (so as to have the greatest overall range available).14. When first setting up your AirLine System in a new environment, it’s always a good idea to do a walkaround in order to make surethat coverage is provided for your entire performance area. Accordingly, turn down the level of your audio system and turn on boththe transmitter and receiver. Then, with the transmitter unmuted, restore the level of your audio system and while speaking or singing,walk through the entire area that will need to be covered. As you do so, observe the “Power On / RF”LED on the AR1 receiver; itshould always remain lit steadily green, indicating that it is receiving sufficiently strong RF signal. Always try to minimize the distancebetween transmitter and receiver as much as possible so that the strongest possible signal is received from all planned transmissionpoints. In fixed installations such as A/V or corporate conference rooms, you may find it handy to mount the AR1 in the supplied wall-mount holder. In certain environments, it may be desirable to angle the receiver antenna differently from its vertical position. Whereextended range coverage is required, a Samson UR1 true diversity receiver (set to the same channel) can be substituted.If you have followed all the steps above and are experiencing difficulties, contact your local distributor or, if purchased in theUnited States, call Samson Technical Support (1-800-372-6766) between 9 AM and 5 PM EST.Setting Up and Using Your AirLine SystemENGLISH
