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.
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.
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 wireless microphone system is the
successful result of years of design and manufacturing experience.
Each 200 Series professional VHF wireless system includes
a receiver and either a body-pack transmitter or a handheld
microphone/transmitter on a specific crystal-controlled
frequency. ATW-201 UniPak
™
body-pack transmitter systems
include models pre-packaged with either an AT-GCW guitar
cable (/G), a PRO8HEcW headworn microphone (/H) or an
AT829cW lavalier mic ( /L) for particular applications. All A-T
Wireless Essentials
™
microphones and cables, available sepa-
rately, are pre-terminated for use with any ATW-201 system.
Because 200 Series packaging is designed to hold all versions
of the system, some compartments in the carton are intentionally left empty.
The ATW-R200 receiver design features a novel “docking”
power supply configuration (patent pending). An AC power
adapter housed in a compartment in the receiver uses an
IEC-standard detachable power cordset. Furthering its flexibility,
the power adapter may be easily removed from the receiver
case, permitting its use as a conventional in-line AC adapter.
The versatile ATW-T201 UniPak body-pack transmitter has both
a high-impedance input for instruments, and a low-impedance
input with bias connection for use with dynamic and electret
condenser microphones. The ATW-T202 handheld transmitter
features a unidirectional dynamic microphone element.
Both the body-pack and handheld transmitters use internal
9-volt batteries and have Off/Standby/On switches, input Trim
(level) adjustments and battery-save switches.
Introduction
See pages 8-9 for illustrations.
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.
Receiver Installation
3
Location
For best operation the receiver should be at least 3' (1 m)
above the ground and at least 3' (1 m) away from a wall or
metal surface to minimize reflections. Keep the receiver
antennas away from noise sources such as digital equipment,
motors, automobiles and neon lights, as well as away from
large metal objects. In multi-channel systems, position
receivers at least 3' (1 m) apart and keep operating transmitters at least 6' (2 m) from the receivers to help assure
maximum RF performance.
Output Connection
The receiver provides unbalanced, aux-level output from a
1
/4"
TS (“mono”) phone jack; an output cable is not included. Use
a shielded audio cable with
1
/4" phone plug to connect the
receiver’s AF Out jack to the mixer/amplifier’s aux-level input.
Power Connection
Turn the receiver’s volume control all the way down. If not
already connected, plug the small DC output cord from the AC
power adapter to the DC power input jack on the back of
receiver. Plug the power cordset into the power adapter, and
then connect the cordset to an AC source.
(Note that the receiver has no power Off/On switch. The
receiver will be energized whenever the power adapter is
connected and plugged into the AC outlet. Unplug the cordset
from the AC outlet whenever the system is not in use – both
for safety, and to conserve energy.)
If desired, the power adapter may be removed from the receiver housing and used as an in-line supply. To remove the
adapter,
gently
pull the release tab
slightly
away from the
housing; then pull the power supply
straight back
out of the
receiver (Fig. A). Extend the 12V DC cord and/or the AC cordset as desired.
Front Panel Controls and Functions (Fig. C)
1. ANTENNAS: Position the “signal” antenna (1a) and
“ground” antenna (1b) as shown in Figure B.
2. POWER INDICATOR: Lights when power is supplied to
the receiver.
3. RF INDICATOR: Lights to show presence of transmitter
signal.
4. AF PEAK INDICATOR: Only lights when audio distortion
is present at maximum modulation. Not affected by
position of Volume control.
5. VOLUME CONTROL: Adjusts the audio level at the
1
/4"
output jack. Does not affect AF Peak indicator.
Antennas
A novel “dipole” antenna system on the receiver improves
operation by providing a “ground” element in addition to the
usual “signal” element. Position the two antennas at 90° in
the form of a “V,” or position the left (“signal”) antenna
vertically and the right (“ground”) antenna horizontally, in the
shape of an “L” (Fig. B). Use the position that performs
better in your operating environment.
Be certain to extend
both antennas to their full 15" (38 cm) length
by holding
them at their bases and pulling out on their caps. Both antenna
elements may be swiveled to the left and right, but do not
attempt to rotate them in a screwing/unscrewing motion. To do
so may damage the antenna and/or receiver. For best
performance, locate the receiver so its antennas are in direct
line-of-sight to the transmitter’s likely operating position.

6. AC POWER ADAPTER: Power supply “docks” inside
receiver housing, but can be removed to be used as an
in-line supply if desired.
7. RELEASE TAB: Pull down
slightly
to permit removal of
power adapter from receiver housing.
8. AC INPUT: Connect the AC cordset here.
9. DC POWER CORD: Connects the power supply’s 12-volt
DC output to the receiver’s DC input jack.
10. DC POWER INPUT: Connect the provided docking
power adapter, or other 12V DC source. (Receiver requires
200 mA.)
11. SQUELCH CONTROL: Adjusts level of noise-muting circuit
(preset at factory but can be adjusted as circumstances
warrant).
12. AUDIO OUTPUT JACK:
1
/4" TS (Tip-Sleeve) or “mono”
phone jack. Use a shielded cable to connect to an
unbalanced aux-level input of a mixer or amplifier.
