Operation is subject to the condition that this device does not cause harmful interference. This device complies with INDUSTRY CANADA R.S.S. 210, en conformité avec IC: RSS-210/CNR210. Operation is subject to the following conditions: 1) This device may not cause harmful interference and 2) this device must accept any interference received, including interference which may cause undesired operation. Changes or modifications not expressly approved by Audio-Technica could void your authority to operate this equipment. CAUTION! Electrical shock can result from removal of the receiver cover. Refer servicing to qualified service personnel. No user-serviceable parts inside. Do not expose to rain or moisture. The circuits inside the receiver and transmitter have been precisely adjusted for optimum performance and compliance with federal regulations. 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 difficulty, 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 medicaldevice provider if you have any questions, or experience any problems with the use of this or any other RF equipment. 700 Series Owners Manual V. 1 5-25-06 Page 2 of 12 Introduction Thank you for choosing an Audio-Technica professional wireless system. You have joined thousands of other satisfied customers who have chosen our products because of their quality, performance and reliability. This AudioTechnica wireless microphone system is the successful result of years of design and manufacturing experience. Each 700 Series wireless system provides a choice of eight PLL synthesized UHF frequencies in the 542-561 MHz band (TV channels 26-29). All 700 Series wireless systems offer both manual and automatic frequency scanning. Each wireless system includes a receiver and either a body-pack or handheld transmitter. Individual components are also available separately. The ATW-R700 receiver features Diversity Reception. Logic circuitry monitors reception, selecting the superior signal from two antennas, providing better sound quality and reducing the possibility of interference and dropouts. Softtouch controls provide convenient access to selection of operating frequency and automatic scanning, while an LED display indicates selected channel and scanning operation. The versatile ATW-T701 UniPak™ body-pack transmitter has both low- and highimpedance 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 guitar and microphone, plus switchable high/low RF power. The ATW-T702 handheld dynamic microphone/transmitter features a rugged dynamic cardioid element designed for professional live-sound venues. Transmitters in the 700 Series use two 1.5V AA batteries for economical operation and wide availability. Both transmitters also feature a multicolor Battery/Power indicator with low-battery indication. 700 Series receivers features a sophisticated Tone Lock™ tone squelch system that opens the receiver’s audio output only when a 700 Series transmitter is detected, reducing the possibility of interference. As a result, 700 Series 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. 700 Series Owners Manual V. 1 5-25-06 Page 3 of 12 Please note that in multiple-system applications there must be a transmitterreceiver 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 eight channels (operating frequencies) that are used in the 700 Series have been selected for multi-channel compatibility. Subject to frequency availability in a particular geographic area, any of these eight channels may be used together. The operating frequencies that correspond to each of the eight channels are listed on page __ 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 reflections. The transmitter should be at least 3 ft. from the receiver, as shown in Fig. A. Keep antennas away from noise sources such as digital equipment, motors, automobiles and neon lights, as well as away from large metal objects. Output Connections There are two audio outputs on the back panel: balanced (12.5 mV) and unbalanced (25 mV). 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. Antennas Extend the permanently attached UHF antennas. The antennas are normally positioned in the shape of a “V” (both 45° from vertical) for best reception. Diversity Indicators on the receiver front panel will indicate which antenna is active. 700 Series Owners Manual V. 1 5-25-06 Page 4 of 12 Power Connections Connect the DC plug on the included AC power adapter to the DC power input on the back of the receiver. Secure the cord over the cord hook on the back of the receiver, to keep the plug from being detached by an accidental tug on the cord. Then plug the adapter into a standard 120 Volt 60 Hz AC power outlet. Receiver Controls and Functions Front Panel Controls and Functions (Fig. B) 1. ANTENNAS: Position the antennas as shown in Figure B. Fully extend both antennas by pulling on the endcaps. 2. AF PEAK INDICATOR: Indicates when maximum transmitter modulation without distortion has been reached. Not affected by position of Volume control. 3. LED WINDOW: LED Display indicates channel setting and scanning operation. 4. DIVERSITY INDICATORS: Indicates which antenna (A or B) has better reception and is in operation. 5. SELECT BUTTON: Touch Set/Scan button once to enable operation (Channel number will flash). Touch the Select button to manually select desired channel. The selected number will flash on and off. Press and hold Set/Scan button to set the channel (operating frequency).

SET/SCAN BUTTON: Two distinct operations are associated with this button: Touch: A momentary press of the Set/Scan button. Hold: A press and hold (about two seconds) of the Set/Scan button. The Set/Scan button can be used in two ways: Manual Set Mode, to permit selection of an operating channel; and Automatic Scan/Set Mode, to initiate the automatic channel scan and selection, as follows: Manual Set Mode: After using the Select button to arrive at desired channel, hold the Set/Scan button to set the channel. NOTE: Before the 700 Series Owners Manual V. 1 5-25-06 Page 5 of 12 channel has been set, a touch of the Set/Scan button will revert the channel to its previous setting. Automatic Set Mode: Hold the Set/Scan button. The Automatic Scan/Set Mode will automatically scan for and set the next open channel. Rear Panel Controls and Functions (Fig. C) 8. AF LEVEL CONTROL: Adjusts audio output level of both AF Output jacks; maximum output is fully clockwise. 9. BALANCED AUDIO OUTPUT JACK: XLRM-type connector. A standard 2-conductor shielded cable can be used to connect the receiver output to a balanced microphone-level input on a mixer or integrated amplifier. 10. UNBALANCED AUDIO OUTPUT JACK: 1/4" phone jack. Can be connected to an unbalanced aux-level input of a mixer, guitar amp or tape recorder. 11. POWER INPUT JACK: Connect the DC plug from the included in-line AC adapter. 12. CORD HOOK: Loop the cord around the cord hook to keep the DC plug from pulling out accidentally. Transmitter Controls and Functions Battery Selection Two 1.5V AA alkaline batteries are recommended. UniPak™ Transmitter Battery Installation 1. Slide the transmitter door open by first pulling the catch down. (Fig. D) 2. Observe correct polarity as marked and carefully insert two fresh 1.5V AA alkaline batteries (Figure D). 3. Slide the door closed, making certain it clicks securely in Figure D—UniPak™ Transmitter Open [Note: After Channel Selector Switch use the following copy: Select channels 1-8; channels 9 and 0 are for service adjustment.] Handheld Transmitter Battery Installation 4. Unscrew the lower body cover, slide it downward, and remove it to expose the battery compartment. (Fig. D) 700 Series Owners Manual V. 1 5-25-06 Page 6 of 12 5. Observe correct polarity as marked inside the battery compartment and carefully insert two fresh 1.5V AA alkaline batteries. Insert the first battery and slide it down. Then insert the second battery into the space remaining. Make certain the batteries are fully seated in the battery compartment. (Fig. E) 6. Slide the lower body cover back and up body, the screw the housing together. Do not overtighten. Note: Remove batteries from the handheld transmitter starting at the bottom end, where finger indents in the battery housing are provided for easy grip. Figure E—Handheld Transmitter Battery Compartment Battery Indicator After the battery is installed, press and hold the power button until the battery indicator LED turns green. (It will turn red first; keep holding until it turns green). If the battery indicator LED does not turn green, the batteries are installed incorrectly or they are dead Figure F—UniPak Transmitter Top View Figure G—Handheld Transmitter Bottom View UniPak Transmitter Input Connection Connect an audio input device (microphone or guitar cable) to the audio input connector on the top of the transmitter. A number of Audio-Technica professional microphones and cables are available separately, pre-terminated with a UniPak input connector (see “Optional System Accessories” on page [NEED PAGE NUMBER]). Transmitting Antenna The UniPak transmitter includes a permanently-attached flexible antenna. For best results, allow the antenna to hang freely and full length from the bottom of the transmitter. If the received signal is marginal, experiment with different transmitter positions on your body or instrument; or try repositioning the receiver. Do not attempt to remove, replace or change the length of the transmitting antenna. System Operation Plug in receiver. Receiver On… 700 Series Owners Manual V. 1 5-25-06 Page 7 of 12 The LCD display will light up. If either A or B diversity indicators lights up at this point (without transmitter on) there may be interference in the area. If this occurs, change channels (select another frequency). How to Make Operating Channel Changes on Receiver Operating channel changes (frequency changes) may be made in two ways: manually and automatically. To change the channel manually: 1. Touch Set/Scan button once to enable operation of Select button (Channel number will flash). Touch the Select button to manually select desired channel. The selected number will flash on and off. 2. Hold Set/Scan button to set the channel (operating frequency). If the Set/Scan button is not pressed within 10 seconds to confirm the selection, then the system will revert back to its original channel. To change the channel automatically: 1 Hold the Set/Scan button for about 2 seconds. The current channel will flash three times quickly; then the system will begin to scan for the next open channel. When it finds an open channel, it will flash the open channel three times and then set the channel. (If an open channel is not found, the automatic scan will stop when it returns to the original channel.) Transmitter On… Before turning on the transmitter, use the provided screwdriver to set the transmitter channel selector switches (Fig….) to the same number that is displayed on the receiver. (Select channels 1-8; channels 9 and 0 are for service adjustment.) Always turn the transmitter off when changing channels (frequencies). The transmitters have a soft-touch button. When the transmitter is “on,” the transmitter produces both RF and audio. When the transmitter is switched on and in normal operation, the receiver’s diversity indicators will display which antenna is active. Setting Levels Correct adjustment of transmitter audio input, receiver audio output, and mixer/amplifier input and output levels is important for optimum system performance. ATW-T702 Handheld Transmitters 700 Series Owners Manual V. 1 5-25-06 Page 8 of 12 The 700 Series handheld transmitter has factory pre-set audio input levels. Factory setting is full clockwise, maximum gain. While speaking/singing into the microphone at typically loud levels, check the AF peak indicator on the receiver. If the AF peak indicator is easily illuminated and distortion is heard through the system, it may be necessary to adjust the transmitter audio input level. To adjust the transmitter audio input level, unscrew the lower body cover and slide it downwards, exposing the screwdriver and gain trimmer (Fig. H). Remove the screwdriver and gently turn the gain trimmer control counterclockwise until the AF peak indicator is illuminated only on audio peaks. 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 significantly. 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. Figure H—Handheld Transmitter Interior View ATW-T701 UniPak Transmitter Trimmer adjustments in the UniPak transmitter (Fig. I) 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). For INSTRUMENT: Set GT (guitar trim) control fully clockwise (maximum) and MT (microphone trim) control fully counterclockwise (minimum). 2. Set the receiver’s AF Level control to its full clockwise position (maximum). See Figure C on page . 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 amplifier input level control that will allow audio through the system. 700 Series Owners Manual V. 1 5-25-06 Page 9 of 12 5. For MIC: While speaking/singing into the microphone at typically loud levels, check the AF peak indicator on the receiver. If AF peak indicator is easily illuminated and distortion is heard through the system, it may be necessary to adjust the transmitter audio input level. To adjust the transmitter audio input level, gently turn the microphone level trim control counterclockwise until the AF peak indicator is illuminated only on audio peaks. For INSTRUMENT: While playing the instrument at typically loud levels, check the AF peak indicator on the receiver. If AF peak indicator is easily illuminated and distortion is heard through the system, it may be necessary to adjust the transmitter audio input level. To adjust the transmitter audio input level, gently turn the instrument level trim control counterclockwise until the AF peak indicator 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 amplifier and yet permits the amplifier’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/amplifier is no longer overloaded. Figure I—UniPak Transmitter Open 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.

Available frequ4encies are shown in the chart below. All frequencies may be combined for up to 8 simultaneous operating channels. 700 Series Frequency Channel Plan Channel Frequency-MHz 542.125 545.750 551.500 552.000 557.875 559.375 560.500 561.250 TV Channel 26 27 28 29 Tips To Obtain the Best Results 1. Use only fresh alkaline batteries. Do not use “general purpose” (carbonzinc) batteries. 2. Position the receiver so that it has the fewest possible obstructions between it and the normal location of the transmitter. Line-of-sight is best. 3. The transmitter and the receiver must be set to the same frequency. Set or change transmitter frequency only when its power is turned off. 4. The transmitter and the receiver should be as close together as conveniently possible, but no less than six feet (2 m.). 5. Do not place the receiver antennas within 3’ (1 m) of another receiver or antenna. 6. The receiver antennas should be kept away from any metal. 7. A receiver cannot receive signals from two transmitters at the same time. 8. If the AF Level control of the receiver is set too high, it may over-drive the input of the mixer or clip the output of the receiver, causing distortion. Conversely, if the receiver output is set too low, the overall signal-to-noise ratio of the system may be reduced. Adjust the output level of the receiver so the highest sound pressure level going into the microphone (or the loudest instrument playing level) causes no input overload in the mixer, and yet permits the mixer level controls to 9operate in their “normal” range (not set too high or too low). This provides the optimum signal-to-noise for the entire system. 9. In the UniPak transmitter, the “MT” or “GT” input control not in use should be set to minimum. 10. Turn the transmitter off when not in use. Remove the battery if the transmitter is not to be used for a period of time. Unplug the receiver from the AC outlet when the system is not in use. 700 Series Owners Manual V. 1 5-25-06 Page 12 of 12 For future reference, please record your system information here (the serial numbers appear inside the battery compartment of each transmitter, and on the bottom of each receiver): Receiver ATW-R700 Serial Number__________________________ UniPak™ Body-Pak Transmitter ATW-T701 Serial Number__________________________ Handheld Dynamic Microphone/Transmitter ATW-T702 Serial Number__________________________ One-Year Limited Warranty Audio-Technica professional wireless systems purchased in the U.S.A. are warranted for one year from date of purchase by Audio-Technica U.S., Inc.
