Do not attempt to open the receiver or transmitter. To do so will void the warranty, and may cause improper operation.Notice to individuals with implanted cardiac pacemakers or AICD devices:Any source of RF (radio frequency) energy may interfere with normal functioning of the implanted device. All wireless microphones have low-power transmitters (less than 0.05 watts output) which are unlikely to cause difculty, especially if they are at least a few inches away. However, since a “body-pack” mic transmitter typically is placed against the body, we suggest attaching it at the belt, rather than in a shirt pocket where it may be immediately adjacent to the medical device. Note also that any medical-device disruption will cease when the RF transmitting source is turned off. Please contact your physician or medical-device provider if you have any questions, or experience any problems with the use of this or any other RF equipment.RF Interference Please note that wireless frequencies are shared with other radio services. According to Federal Communications Commission regulations, “Wireless microphone operations are unprotected from interference from other licensed operations in the band. If any interference is received by any Government or non Government operation, the wireless microphone must cease operation...” If you need assistance with operation or frequency selection, please contact your dealer or Audio-Technica. Extensive wireless information also is available at www.audio-technica.com. Thank you for choosing an Audio-Technica professional wireless system. You have joined thousands of other satised customers who have chosen our products because of their quality, performance and reliability. This Audio-Technica wireless microphone system is the successful result of years of design and manufacturing experience.Each 2000 Series wireless system provides a choice of 10 PLL synthesized UHF frequencies in one of ve UHF frequency ranges, available for exible performance in a wide variety of regions worldwide: Frequency Range Band D 656.125 – 678.500 MHz Band E 800.550 – 813.150 MHz Band F 854.900 – 864.900 MHz Band G 722.125 – 744.500 MHz Band I 487.125 – 506.500 MHz The band letter reference at the end of 2000 Series Stock Numbers indicates what band system/component operates in. For simplicity, model numbers used throughout this manual will reference only the basic model number without the band indications. Each wireless system includes a receiver and either a body-pack or handheld transmitter. UniPak® body-pack transmitter systems include accessory microphones for particular applications. All A-T Wireless Essentials® microphones and cables, available separately, are pre-terminated for use with any Audio-Technica 2000 Series wireless system.The ATW-R2100a receiver features true diversity reception. Two antennas feed two completely independent RF sections on the same frequency; automatic logic circuitry continuously compares and selects the superior received signal, providing better sound quality and reducing the possibility of interference and dropouts. The receiver also offers a switchable output attenuator to reduce the level of the output signal by 12 dB for exible use with a variety of system congurations. Switchable antenna power is also provided. Soft-touch controls provide convenient access to selection of operating frequency and automatic scanning, while an LCD information display provides constant monitoring of system operation. The receiver is half-width for a standard 1U 19" rack mount; rack-mount adapters are included. Two receivers can be mounted side by side, using an optional AT8630 joining-plate kit.The versatile ATW-T210a UniPak® body-pack transmitter has both low- and high-impedance inputs plus a bias connection, for use with dynamic and electret condenser microphones, as well as Hi-Z instrument pickups. The UniPak® transmitter also offers separate trim controls for instrument and microphone, plus switchable high/low RF power. The ATW-T220a handheld dynamic microphone/transmitter features the same element used in the PRO 41 dynamic handheld microphone created for professional live-sound venues. It also offers switchable high/low RF power. Both the ATW-T210a UniPak® and ATW-T220a handheld transmitters also offer charging contacts so the units can be placed in an optional recharging station for multi-transmitter charging.For economical operation and wide availability, transmitters in the 2000 Series use two 1.5V AA alkaline batteries or rechargeable two AA NiMH batteries for use with Audio-Technica’s ATW-CHG2 Recharging Station. Both transmitters have battery condition indicators. 2000 Series receivers feature a sophisticated Tone Lock™ tone squelch system that opens the receiver’s audio output only when a 2000 Series transmitter is detected, reducing the possibility of interference. As a result, 2000 Such modifications could void the user's authority to operate the equipment.
2000 Series Installation and Operation 3Series transmitters and receivers must be used together and should not be used with components from other Audio-Technica wireless systems, or with those of other manufacturers.Please note that in multiple-system applications there must be a transmitter-receiver combination set to a separate channel (frequency) for each input desired (only one transmitter for each receiver).Because the wireless frequencies are within UHF TV frequency bands, only certain channels (operating frequencies) may be useable in a particular geographic area. The 10 channels (operating frequencies) per band that are used in the 2000 Series have been selected for multi-channel compatibility. Subject to frequency availability in a particular geographic area, any of these 10 channels may be used together. The operating frequencies that correspond to each of the 10 channels are listed on page 10.Receiver Installation Location For best operation the receiver should be at least 3 ft. (1 m) above the ground and at least 3 ft. away from a wall or metal surface to minimize reections. The transmitter should be at least 3 ft. from the receiver, as shown in Figure A. Keep antennas away from noise sources such as digital equipment, motors, automobiles and neon lights, as well as away from large metal objects.Fig. AOutput ConnectionsThere are two audio outputs on the back panel: balanced and unbalanced. Use shielded audio cable for the connection between the receiver and the mixer. If the input of the mixer is a 1/4" jack, connect a cable from the 1/4" unbalanced audio output on the back of the receiver housing to the mixer. If the input of the mixer is an XLR-type input, connect a cable from the balanced XLR-type audio output on the back panel to the mixer. The two isolated audio outputs permit simultaneous feeds to both unbalanced and balanced inputs. For example, both a guitar amp and a mixer can be driven by the receiver.AntennasAttach the included pair of UHF antennas to the antenna input jacks. The antennas are normally positioned in the shape of a “V” (both 45° from vertical) for best reception.Accessory antennas can be remotely located from the receiver. However, due to signal loss in cables at UHF frequencies, use the lowest-loss RF cables practical for any cable runs over 25 feet. RG8-type is a good choice. Use only copper-shielded cable, not CATV-type foil-shielded wire. Audio-Technica offers quality RF cables in four lengths, as well as remote antennas; see audio-technica.com for a wide selection of wireless system accessories. Antenna Power The antenna input jacks also can provide +12V DC output on their center pins to power inline RF devices. A maximum of 60 mA can be drawn from each of the jacks. While an accidental short-circuit will not harm the internal 12V supply, make certain that an antenna cable shield does not contact the center conductor. Antenna Power is selected by a switch on the back of the ATW-R2100a Receiver. The unit is shipped with the switch in the “off” position. Note: the antennas included with the ATW-R2100a Receiver do not require power. If you have an antenna system that requires power (such as powered antennas or active combiners or splitters) switch the Antenna Power switch to the “on” position. Power Connections Connect the included AC adapter to the DC power input on the back of the receiver. Loop the small cord from the DC plug over the cord hook above the jack, to keep the plug from being detached by an accidental tug on the cord. Operation of the receiver is controlled by the front-panel Power switch.

2000 Series Installation and Operation 7System OperationSwitch on the receiver. Do not switch on the transmitter yet.Receiver On…The LCD display will light up and one of the tuner operation indicator LCD segments (A or B) will light, even though the transmitter is not on. If two or more of the RF LCD segments light up at this point, there may be RF interference in the area. If this occurs, change operating channels (select another frequency).How to Make Operating Channel ChangesOperating channel changes (frequency changes) may be made in two ways: manually and automatically. To change channel manually 1. Use the Up/Down arrow buttons to reach the desired channel number.2. Hold the Set/Scan button until the channel number stops ashing to set the receiver to the channel indicated. NOTE: Before the channel has been set, a touch (momentary press) of the Set/Scan (rather than a hold) will revert the channel to its previous setting.To change channel automatically1. Hold the Set/Scan button. The Automatic Scan/Set Mode will automatically scan for and set the next open channel. LCD screen will ash “FS” four times to indicate start of scan.Transmitter On…Before turning on the transmitter, use the provided screwdriver to set the transmitter channel selector switches (Fig. E/I) to the same numbers as those displayed on the receiver. Always turn the transmitter off when changing channels (frequencies).The transmitters have a two-position, on-off power switch. When the switch is “On,” the transmitter produces both RF and audio.The transmitters have a two-position RF power select switch, offering low/high transmission modes to conserve battery life/maximize power. Factory setting is high. There is about a half-second delay after the transmitter is switched to the “On” position before the receiver’s Tone Lock squelch un-mutes the receiver.When the transmitter is switched on and in normal operation, the receiver’s RF signal level indicators will display as dark segments (signal strength indicators) from bottom to top at the left side of the LCD display.Setting LevelsCorrect adjustment of transmitter audio input, receiver audio output, and mixer/amplier input and output levels is important for optimum system performance.ATW-T220a Handheld TransmitterThe 2000 Series handheld transmitter has factory pre-set audio input levels. Factory setting is full clockwise, maximum gain. 1. While speaking/singing into the microphone at typically loud levels, check the AF meter levels on the receiver. If all ve AF meter bars are consistently illuminated and distortion is heard through the system, it may be necessary to adjust the transmitter audio input level.2. To adjust the transmitter audio input level, unscrew the lower body cover and slide it downwards, exposing the screwdriver and level trim control (Fig. I ). Remove the screwdriver and gently turn the level trim control counterclockwise until the topmost receiver AF level meter bar is illuminated only on audio peaks. 3. Return the screwdriver to its clip and close and secure the lower body. No further transmitter gain adjustments should be needed, as long as the acoustic input does not change signicantly.CAUTION! The small trimmer controls are delicate; use only the supplied screwdriver. Do not force the trimmers beyond their normal 180° range of rotation. Return the screwdriver to its storage clip when not in use.Fig. I – Handheld Transmitter Interior ViewCharging ContactsRF Power Select SwitchService Port (for factory use only)Channel Selector SwitchLevel Trim ControlScrewdriver
2000 Series Installation and Operation8Setting Levels (Continued)ATW-T210a UniPak® TransmitterTrimmer adjustments in the UniPak® transmitter (Fig. E) will enable you to use microphones or instruments with different output levels.1. For MIC: Set microphone level trim control fully clockwise (maximum) and instrument level trim control fully counterclockwise (minimum). Factory setting is fully clockwise (maximum). For INSTRUMENT: Set instrument level trim control fully clockwise (maximum) and microphone level trim control fully counterclockwise (minimum). Factory setting is fully clockwise (maximum).2. Set the receiver’s AF Level control to its full clockwise position (maximum). See Figure D on page 5.3. Plug the mic or instrument into the transmitter and power up the system.4. For MIC: Make an initial adjustment of the mixer’s level controls that will allow audio through the system. For INSTRUMENT: Make an initial adjustment of the instrument amplier input level control that will allow audio through the system.5. For MIC: While speaking/singing into the microphone at typically loud levels, check the AF meter levels on the receiver. If all ve meter bars are consistently illuminated and distortion is heard through the system, it may be necessary to adjust the UniPak transmitter audio input level. To adjust the transmitter audio input level, gently turn the microphone level trim control counterclockwise until the topmost receiver AF level meter bar is illuminated only on audio peaks. For INSTRUMENT: While playing the instrument at typically loud levels, check the AF meter levels on the receiver. If all ve meter bars are consistently illuminated and distortion is heard through the system, it may be necessary to adjust the UniPak transmitter audio input level. To adjust the transmitter audio input level, gently turn the instrument level trim control counterclockwise until the topmost receiver AF level meter bar is illuminated only on audio peaks.6. For MIC: While again speaking/singing into the microphone at typically loud levels, adjust the mixer’s input trim control so the highest sound pressure level going into the microphone causes no input overload in the mixer, and yet permits the mixer’s channel and output level controls to operate in their “normal” range (not set too high or too low). For INSTRUMENT: While again playing the instrument at typically loud levels, adjust the receiver’s AF Level control so the highest signal level causes no input overload in the instrument amplier and yet permits the amplier’s input level controls to operate in their “normal” range (not set too high or too low). Note: If the mixer cannot be adjusted to operate in its normal range without distortion, adjust the receiver’s AF Level Control (turn counterclockwise) until the mixer/ amplier is no longer overloaded.Fig. E – UniPak® Transmitter OpenReceiver SquelchThe squelch control on the back panel of the receiver is preset at the factory for best system performance (factory setting is full counterclockwise), but can be adjusted if you must use the system in an area with considerable RF interference. If there is interference in the audio, and changing the channel is not an option, adjust the squelch control so the system will receive the signal from your transmitter but will “squelch” or eliminate the unwanted background RF noise. This adjustment can cause a reduction in useable range of the wireless transmitter, so set the control to the lowest position that reliably mutes the unwanted RF signals.Transmitter DoorAntennaAudio Input JackInstrument/Microphone Level Trim ControlsChannel Selector SwitchRF Power Select SwitchService Port (for factory use only)Battery-keeper Arm with Screwdriver attachedPower-on LED
