U100 Series Compatible with 7000 Series Wireless
For greater convenience and flexibility, receivers and transmitters in the Audio-Technica U100 Series and 7000 Series are
available individually and may be used interchangeably. All are 100-channel, PLL-synthesized UHF units operating in one of
two UHF frequency ranges: “x” units in 656-668 MHz, and non-”x” units in 728-740 MHz. Model “x” transmitters must
be used only with “x” receivers; the same holds true for non-”x” transmitters and receivers.

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 system is the successful result of years of design
and manufacturing experience.
The U100 systems are designed primarily for use in audio-forvideo applications, with the receiver mounted on a camera and
connected to the camera’s audio input. U100 systems provide
a choice of 100 PLL-synthesized UHF frequencies in one of
two UHF frequency ranges: “x” units in 656-668 MHz, and
non-”x” units in 728-740 MHz. Each system includes a
receiver and either a body-pack or plug-on transmitter:
System Receiver Transmitter
ATW-U101 ATW-R100 ATW-T101 Body-pack
ATW-U101x ATW-R100x ATW-T101x Body-pack
ATW-U102 ATW-R100 ATW-T102 Plug-on
ATW-U102x ATW-R100x ATW-T102x Plug-on
The ATW-R100(x) 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 dropouts.
Front-end helical filter design improves rejection of
interference. The receiver also offers balanced audio output
with level control, a headphone jack with volume control,
removable antennas, a hinged battery door, and LED
indicators. It operates on two internal 9V batteries or external
12V DC.
Each transmitter is powered by one internal 9V battery and
has an Off/Standby/On switch, input level control, battery
condition indicator and channel selector switches. The
ATW-T101(x) body-pack transmitter has an industry-standard
TB5M input connector with both low- and high-impedance
inputs plus a bias connection. The ATW-T102(x) has a 3-pin
XLRF-type input connector with a locking collar.
Note: Since “x” and non-”x” units operate in different
frequency ranges, they are not compatible. Model “x”
transmitters must be used only with “x” receivers; the same
holds true for non-”x” transmitters and receivers.
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). Because the operating frequencies of U100 Systems
are in UHF TV frequencies, only certain wireless frequencies
may be useable in a particular geographic area. Also, only
certain of the available operating frequencies may be used
together. Suggestions for multiple-system frequency grouping
will be found on pages 9 and 10.
Warning: To prevent fire or shock hazard,
do not expose this appliance to rain or
moisture.
Attention: Pour prévenir feu ou choc
électrique, ne pas exposé l’appareil à la
pluie ou à l’humidité.
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 Setup
Location
The ATW-R100(x) receiver is designed primarily to be
mounted to professional video cameras using the included
hook & loop fasteners (mounting methods and positions will
vary with the camera being used). However, the receiver
will provide outstanding professional performance in other
wireless applications as well.
For best operation the receiver should be at least three feet
above the ground and at least three feet away from a wall or
metal surface to minimize reflections. The transmitter should
be at least three feet from the receiver.
Keep antennas away from noise sources such as computers,
motors, automobiles and neon lights; also keep antennas
away from large metal objects.
Output Connections
There is one balanced audio output (31.6 mV) on the back
panel of the receiver. Use shielded audio cable to connect this
XLRM-type 3-pin jack to the mic audio input of the camera or
mixer. (The optional AT8341 cable, 19" long, terminates in a
right-angle 3.5 mm stereo mini-plug.)
A headphone jack and level control permit monitoring of
the audio signal. Either mono or stereo headphones with
a 3.5 mm plug may be used; the audio is supplied to both
sides of a stereo unit.
Antennas
Attach the antennas to the antenna input jacks. Make certain
that during operation there is a clear open-air path between
the receiver antennas and the transmitter.
Power
The ATW-R100(x) receiver operates on either external DC or
internal battery power by setting the Power switch to “EXT”
or “INT” respectively (Fig. A). In the center position all power
is off.
External Power
The back panel is equipped with a jack for an external
12-18V DC source, 200 mA nominal current. The jack takes a
standard 2.5 mm I.D. coaxial DC power plug, center
positive
.
Battery Selection and Installation
Always use two fresh alkaline 9V batteries. Replace the
batteries in pairs. Turn the Power switch “Off” before
inserting the batteries.
Open the hinged battery door on the side of the receiver.
Insert two batteries, observing correct polarity as marked
on the inside of the door. Close and latch the door.
Note that the battery door will not close fully if the batteries
are installed incorrectly.
Do not force the door closed.
The U100 Series receiver and transmitters accept most
popular brands of 9-volt alkaline batteries. But there is
considerable variation in battery sizes; some alkaline and
extended-life batteries may not fit correctly, which can cause
units to operate improperly or not at all.
