Installation and Operation
This device complies with part 15 of the FCC Rules. 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.
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.

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.

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.

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.

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.

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.

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

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.

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.

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.
