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
ny interference received, including interference which
a
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 “bodypack” 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.
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 Audio-Technica wireless
microphone system is the successful result of years of design
and manufacturing experience.
The ATW-R700 receiver features Diversity Reception. Logic
ircuitry monitors reception, selecting the superior signal from
c
two antennas, providing better sound quality and reducing the
possibility of interference and dropouts. Soft-touch 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
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
separate trim controls for guitar and microphone, plus
switchable high/low RF power.
The ATW-T702 handheld dynamic microphone/transmitter
features a rugged dynamic unidirectional 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 multi-color Power/Mute/Battery indicator.
700 Series receivers feature a sophisticated Tone Lock
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 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 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 7.

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.

Receiver Installation
ocation
L
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 Figure A. Keep
ntennas away from noise sources such as digital equipment,
a
motors, automobiles and neon lights, as well as away from
large metal objects.
Figure A
Output Connections
There are two audio outputs on the back panel: balanced
(-16.5 dBV) and unbalanced (-13.5 dBV). Use shielded audio
cable for the connection between the receiver and the mixer. If
the input of the mixer is a
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.

/4" jack, connect a cable from the1/4"
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.
Receiver Controls and Functions
Figure B1-Antenna Position

1. ANTENNAS: Position the antennas as shown in Figure B1.
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 (Fig. C).
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 (for manual channel selection):
Press the Select button repeatedly until desired channel is
reached. Press and hold the Set/Scan button to manually
set the receiver to indicated channel. Channel number will
stop flashing. (A brief touch of the Set/Scan button will
revert to previously set channel). If the Set button is not
pressed within 10 seconds to confirm the selection, the
system will revert to its original channel.

6. SET/SCAN BUTTON: The Set/Scan button can be used in
two ways: 1) in conjunction with the Select button to permit
manual selection of an operating channel in Manual Set
Mode (see “Select button” description above); and 2)
Automatic Scan/Set Mode, to initiate the automatic channel
scan and selection, as follows:
Automatic Scan/Set Mode: Press and hold the Set/Scan
button for about two 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 return to the original channel and flash 5 times.)
