Audio Technica ATW-2120 Installation And Operation Manual page 2

Professional UHF Wireless Systems
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 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.
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.
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.
Each 2000 Series wireless system provides a choice of 10 PLL-
synthesized UHF frequencies in the 656-678 MHz band (TV
channels 45-48). Each wireless system includes a receiver
and either a body-pack or handheld transmitter. Individual
components are also available separately.

Installation and Operation
The ATW-R2100 receiver features true diversity reception. Two
antennas feed two completely independent RF sections on
the same frequency; automatic logic circuitry continuously
compares and selects the superior received signal, 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 LCD information display provides constant monitoring
of system operation. The receiver is half-width for a standard
1U 19" rack mount; rack-mount adapters are included. Two
receivers can be mounted side by side, using an optional
AT8630 joining-plate kit.
The versatile ATW-T210 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 ATW-T220 handheld dynamic microphone/transmitter
features the same element used in the PRO 41 dynamic
handheld microphone created for professional live-sound
venues.
Transmitters in the 2000 Series use two 1.5V AA batteries for
economical operation and wide availability. Both transmitters
have battery condition indicators.
2000 Series receivers feature a sophisticated Tone Lock™
tone squelch system that opens the receiver's audio output
only when a 2000 Series transmitter is detected, reducing the
possibility of interference. As a result, 2000 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 10 channels
(operating frequencies) that are used in the 2000 Series have
been selected for multi-channel compatibility. Subject to
frequency availability in a particular geographic area, any of
these 10 channels may be used together.
The operating frequencies that correspond to each of the 10
channels are listed on page 11.
