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 compli-
ance with federal regulations. Do not attempt to open the
receiver or transmitter. To do so will void the warranty,
and may cause improper 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. Changes or
modifications not expressly approved by Audio-Technica
could void your authority to operate this equipment.
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.
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 multi-color 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.
Introduction
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, especial-
ly 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 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.
