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 european regulations (R & TTE directive). 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 EN300 422-1, EN301 489-09
(EMC) and EN60065.
The ATW-R160, ATW-T161, ATW-T162 and ATW-T163 are
intended to be used in all countries of the European Union.
Please note :
Frequency usage is different for each country. Your AudioTechnica agent will have all the necessary details on the
available legal frequencies for your area.
The ATW-R160 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 a variety of functions, 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 AT8616 joining-plate kit.
The versatile ATW-T161 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-T162 handheld dynamic microphone/transmitter
features a hyper cardioid element created for professional livesound venues.
The ATW-T163 handheld condenser microphone/transmitter
features a cardioid element created for professional live-sound
venues and installations, such as use with inductive loop
systems.
Transmitters in the 1600 Series use two 1.5V AA batteries for
economical operation and wide availability.
Tone squelch system in the ATW-R160 receiver opens only
when a 1600 Series transmitter is detected, reducing the possibility of interference. As a result,
1600 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 frequency
for each input desired (only one transmitter for each receiver).
Due to the wireless frequencies being within UHF TV frequency
bands, only certain operating frequencies may be useable in
a particular geographic area.
Please contact your National Radio Licensing Authority for
further information.

Introduction
Notice to individuals with implanted car
diac 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.
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 1600 Series wireless system provides a choice of PLL-synthesized UHF frequencies. Each wireless system includes a
receiver and either a body-pack or handheld transmitter.
Individual components are also available separately.
CAUTION! Do not expose batteries to excessive heat, such as
direct sunlight or open fires.
Receiver Installation
3
Location
For best operation the receiver should be at least 1 m above
the ground and at least 1 m away from a wall or metal surface
to minimise reflections. The transmitter should be at least 1 m
from the receiver, as shown in Figure A.
Keep antennas away from noise sources such as digital equipment, motors, automobiles and neon lights, as well as large
metal objects.
Output Connections
There are two audio outputs on the back panel: balanced
(32 mV) and unbalanced (52 mV). Use shielded audio cable for
the connection between the receiver and the mixer. If the input
of the mixer is a
1
/4" jack, connect a cable from the 1/4" unbalanced audio output on the back of the receiver housing
to the mixer. If the input of the mixer is an XLR-type input, connect a cable from the balanced XLR-type audio output on the
back panel to the mixer. The two isolated audio outputs permit
simultaneous feeds to both unbalanced and balanced inputs.
For example, both a guitar amp and a mixer can be
driven by the receiver.
Antennas
Attach the included pair of UHF antennas to the antenna input
jacks. The antennas are normally
positioned in
the shape of a
“V” (both 45° from vertical) for best reception.
Antennas can be remotely located from the receiver. However,
due to signal loss in cables at UHF frequencies, use the
lowest-loss RF cables practical for any cable runs over 25 feet
(8 m ). RG8-type is a good choice. Use only copper-shielded
cable, not CATV-type foil-shielded wire. Audio-Technica offers
quality RF cables in four lengths, as well as remote antennas;
see the Optional System Accessories section on page 9.
Power Connections
Connect the supplied AT 220 ~ 240V, 50Hz AC adapter to the
DC power input on the back of the receiver. Operation of the
receiver is controlled by the front-panel Power switch.

Transmitter Setup
Battery Selection and Installation
Each transmitter uses two 1.5V AA batteries, not included.
Alkaline type is recommended. Always replace both batteries.
Make certain the transmitter power is Off before replacing
batteries.
UniPak™ Transmitter Battery Installation
1. Slide off the battery cover as shown in Figure E.
2. Observe correct polarity as marked inside the battery
compartment, and carefully insert two fresh 1.5V AA
alkaline batteries.
3. Replace the Battery cover (Figure.E)
Figure E
Figure F
Handheld Transmitter Battery Installation
1. While holding the upper part of the transmitter body just
below the ball-screen, unscrew the lower body cover and
slide downward to remove and expose battery
compartment.
2. Be certain to observe correct polarity as marked inside
the battery compartment (Figure G) and carefully insert
two fresh 1.5V AA alkaline batteries. Make certain the
batteries are fully seated in the battery compartment.
3. Replace the lower body cover. Do not overtighten.
Figure G
Figure H
Battery Condition Indicator
The Green Battery condition indicator(Figure I/ J) should light
strongly with a fresh battery. As the battery weakens, the
indicator will glow Red. When the Indicator becomes Red, there
is little life left in the battery. Replace it at once for continued
operation of the transmitter.
Battery Save Switch
ATW-T161 Transmitter features
RF Lo / Hi Power switch
(Figure
E). As supplied, the switch is set in the Lo (Low)
position for the maximum battery life. Hi(High) position can be
selected for maximum range (Note range decreases when the
switch is set at Lo position.)
Special Note: If accessing de-regulated frequencies between
863 to 865MHz(Ch. C to F), ATW-T161 must be set to RF
Low.

UniPak Transmitter Input Connection
Connect an audio input device (microphone or guitar cable)
to the audio input connector on the bottom of the transmitter.
A number of Audio-Technica professional microphones and
cables are available separately, pre-terminated with a UniPak
input connector (see “Optional System Accessories” on
page 9).
Transmitting Antenna
The UniPak transmitter includes a permanently-attached
flexible antenna. For best results, allow the antenna to hang
freely and full length from the bottom of the transmitter. If the
received signal is marginal, experiment with different transmitter positions on your body or instrument; or try repositioning
the receiver. Do not attempt to remove, replace or change
the length of the transmitting antenna.
The antenna for the ATW-T162 and ATW-T163 handheld
transmitters are located at the bottom of the units. For
the
best
results, hold the Microphone naturally around the
centre of the body.
Holding or otherwise covering antenna housing may affect
operating range.
