Installation and 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.
The versatile ATW-T701 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
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
multicolor Power/Mute/Battery indicator.
700 Series receivers feature 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
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.
Location (fig.A)
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 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 (-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
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.
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 230 Volt
50 Hz AC power outlet.
Introduction
Receiver Installation
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 medical-device provider if you have any questions,
or experience any problems with the use of this or any other RF
equipment.
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.
Each 700 Series wireless system provides a choice of eight PLL
synthesized UHF frequencies in the E-Band: 800 - 820 MHz (TV
channels 62 - 64) F-Band: 840 - 865 MHz (TV channels 67 - 69) and the
U-band: 606 - 630MHz (TV channels 38-40). 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. Soft-touch controls provide convenient
access to selection of operating frequency and automatic scanning,
while an LED display indicates selected channel and scanning operation.

CAUTION! Do not expose batteries to excessive
heat, such as direct sunlight or open fires.
