Description
The ATW-R2100a is a True Diversity UHF wireless receiver operating in
the UHF bands of 656.125–678.500 or 487.125–506.500 MHz. The
automatic frequency scanning eliminates the need for searching for
clear channels and automatically selects the most appropriate frequency
for the area in which the wireless is operating. A pre-coordinated integral
channel plan allows for simultaneous operation of any of the ten channels
in a given location. The flexibility in programming both the receiver and
transmitters eliminates confusing frequency groups and other frequency
coordination problems. A two-position switch turns on/off 12V AC antenna
power for use with powered antennas or accessories. Advanced
Tone Lock™ adjustable squelch system fights interference. High
sensitivity dual IF design using true diversity operation with silent
automatic switching provides dropout-free performance. Front panel LCD
receiver display provides continuous indication of transmitter RF signal
strength, selection of internal dual (True Diversity) receiving sections
(A&B), along with the audio modulation level of the received signal. Both
balanced XLR-type and unbalanced
1

4
" output connections with output
gain adjustments are located on the rear panel. The XLR-type output
includes a ground lift switch to prevent ground loops. Features not often
found in other receivers include metal receiver construction, detachable
wave receiver antennas, AC or 12–18V DC operation, front panel power
switch, and included rack mount kit.
Architect’s and Engineer’s Specifications
The frequency-agile FM wireless receiver shall be part of a wireless
microphone system offered in two UHF bands, 656.125 – 678.500 and
487.125 – 506.500 MHz. It shall be capable of operating on any of 10
PLL-synthesized channels. Simultaneous operation of any of the ten
channels shall be possible without the need for frequency groups or
presets.
The all-metal receiver shall provide an automatic scanning function to
select appropriate local usable channels for proper wireless system
operation. All receiver functions of the receiver shall be controlled by
soft-touch controls on the receiver front panel. It shall be a True Diversity
receiver with two independent internal receiver sections, automatically
selecting the highest quality signal for the receiver’s output. A two-position
switch shall turn on/off the12V AC antenna power for use with powered
antennas or accessories. The system will be equipped with a Tone Lock™
digital identification system to ensure that only the desired wireless
microphone transmitter allows the receiver to be un-muted. Visual
indication of the channel selected shall be provided on the front panel.
The receiver shall continuously monitor and display the RF signal strength
and the selection of internal dual (True Diversity) receiver sections along
with the audio modulation level of the received signal. A front panel
power switch shall be provided along with illuminated display indicating
receiver is active.
The receiver shall have a rear panel selector to lift the ground connection
from pin 1 of the XLR-type output connector to prevent ground loops.
Both XLR-type and 1/4" audio output connections shall be provided.
Output gain and squelch level adjustments shall be provided on the rear
panel of the receiver. The receiver shall be able to be powered by 120V
AC 60 Hz or 12–18V DC at 500 mA.
The receiver as supplied can be rack-mounted singly or in pairs in a single
rack space. The receiver’s design shall provide totally silent audio output
mute when the wireless transmitter is turned off or signal is lost. The
wireless receiver and the supplied metal rack-mounting brackets shall be
industrial black.
The FM wireless receiver shall be an Audio-Technica ATW-R2100a or
equivalent.
