antenna power for use with powered antennas or accessories.
The ATW-T210a UniPak® body-pack transmitter features a latching cover
to protect the internal controls from being accidently activated and a
recessed 4-pin HRS-type locking input connector to increase the life
of the microphone cable. Inputs are available on the transmitter for
low impedance microphone, and high impedance musical instrument
or line input. The transmitter supplies DC bias voltage to power condenser
microphones. A straightforward recessed power/mute switch allows for
operation without the need to look at the transmitter. A red LED power/
battery indicator glows when the transmitter is turned on and the batteries
are in operating condition. An RF power select switch offers high and
low settings.

Description
The 2000 Series frequency-agile True Diversity UHF wireless systems
deliver professional audio and RF performance unheard of in its class.
Straightforward setup, automatic scanning, and other advanced wireless
features brings its performance to a standard that provides the audio
quality and reliability necessary for the quality sound systems of today.
The ATW-R2100a receiver features automatic frequency scanning that
eliminates the need for searching for clear channels by automatically
selecting 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.
Advanced Tone Lock™ adjustable squelch system fights interference.
Features not often found in other receivers include balanced XLR-type and
unbalanced 1/4" output connections, ground-lift switch on XLR-type output,
metal receiver construction, detachable receiver antennas, field replaceable body-pack transmitter antenna, high-pass filter, adjustable squelch,
The ATW-T220a handheld transmitter uses a PRO 41-type dynamic
unidirectional capsule to maintain sonic consistency with wired counterparts. Adjustable trim control helps match the microphone to the audio
source and an ergonomically designed handle and end-mounted recessed
controls help maintain a clean uncluttered appearance. A rugged steel
head case protects the capsule while providing relief from wind-induced
noise. Both transmitters function with standard readily available AA alkaline
batteries providing over 8 hours of operation and feature an easy-to-configure
channel selection switch. An RF power select switch offers high and
low settings.
Architect’s and Engineer’s Specifications
The frequency-agile FM wireless microphone system shall consist of a
receiver and appropriate transmitter. Offered in two UHF bands, 656.125–
678.500 and 487.125 – 506.500 MHz, the wireless system 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 frequency-agile FM wireless receiver shall be all-metal and shall provide
an automatic scanning function to select appropriate local usable channels
for proper wireless system operation. 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.
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. A two-position switch shall
turn on/off the12V AC antenna power for use with powered antennas or
accessories.
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 frequency-agile FM wireless body-pack transmitter shall be part of a
wireless system operating in the UHF bands of 656.125 – 678.500 or
487.125 – 506.500 MHz. The body-pack transmitter shall have inputs for
microphone and line level inputs. It shall provide DC voltage to power
microphones requiring DC bias. The body-pack transmitter shall have a
69
2000 Series
reversible clip allowing for up or down cable entry. A two-position positiveaction mechanical power/mute switch operable without looking at the
transmitter shall be provided. Transmitters using separate mute and power
buttons shall be unacceptable. The transmitter shall have a recessed input
connector and illuminated indicator to indicate battery condition. Ten
selectable channels shall be available. Channel selection shall be via a
recessed rotary selector and the proper tool shall be included with the
transmitter. An RF power select switch shall offer high and low settings.
The device shall have an LED indicator when it is turned on. There shall
be individual trim adjustments on each input. The transmitter shall include
Tone Lock™ to identify the wireless transmitter to the wireless receiver.
This transmitter shall operate on two AA batteries. All channel settings
and level adjustments shall be hidden behind a latching cover to prevent
unnecessary access. The transmitter shall have a removable and field
replaceable antenna.
The frequency-agile FM wireless handheld transmitter shall incorporate a
cardioid dynamic element shall be part of a wireless system operating in the
band of 656.125 – 678.500 MHz. The element shall be protected by a rugged
metal head case with integral two-stage pop filter. A two-position positiveaction mechanical power/mute switch operable without looking at the
transmitter shall be provided. Transmitters using separate mute and power
buttons shall be unacceptable. The transmitter shall have an illuminated
indicator to signify battery condition. 10 selectable channels shall be
available. Channel selection shall be via a recessed rotary selector and the
proper tool shall be included with the transmitter. An RF power select switch
shall offer high and low settings. The device shall have an LED indicator
when it is turned on. There shall be a trim adjustment to allow input gain
changes. The transmitter shall include a Tone Lock™ to identify the wireless
transmitter to the wireless receiver. This transmitter shall operate on two AA
batteries. All channel settings and level adjustments shall be hidden behind
a removable cover to prevent unnecessary access. The transmitter shall
have an integral antenna and be constructed of high-impact materials.
A heavy-duty stand clamp shall be included with the transmitter.
