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-for-
video 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.

Battery Selection and Installation
Always use a fresh alkaline 9V battery. Turn the Power switch
“Off” before inserting a battery.
Open the hinged battery door. Insert the battery, observing
correct polarity as marked inside the battery compartment.
Close the battery door.
Do not force the door closed.
Battery Condition Indicator
After the battery is installed, turn the power on. The battery
condition indicator LED (Fig. B) should flash momentarily.
If it does not, the battery is installed incorrectly or it is dead.
If the indicator LED stays on (does not flash), the battery
voltage is low and the battery should be replaced. If this
happens during use, replace the battery immediately to
ensure continued operation.
ATW-T101(x) Input Devices
Connect a microphone or audio cable to the audio input
connector on the transmitter. Microphones and input cables
pre-terminated with a matching TA5F connector are listed on
page 8.
ATW-T101(x) Input Jack Connections
The ATW-T101(x) body-pack transmitter has an industry-
standard TB5M input connector with both low- and high-
impedanceinputs plus a bias connection.
Transmitting Antenna
The ATW-T101(x) body-pack 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 try
repositioning the receiver. Do not attempt to remove, replace
or change the length of the transmitting antenna. (The
stainless-steel mounting clip may be oriented in one of four
“directions.” Loosen its mounting screw, reposition the clip
in the case recess as desired and re-tighten the screw.)

ATW-T102(x) Microphone Input
The ATW-T102(x) plug-on transmitter has a 3-pin XLRF-type
input connector with a locking collar. Use a dynamic
microphone, or a condenser mic with an internal battery. To
attach the microphone, rotate the threaded locking collar
fully
clockwise (“down”) until it reaches the transmitter housing
(Fig. E1). Then rotate the collar back “up” one or two turns to
expose the microphone latch.
Press the microphone and transmitter together (Fig. E2),
making certain that the latch “clicks” into the base of the mic.
Pull on the mic to make certain it is latched on the connector.
Continue to rotate the threaded collar “up” until it is
firmly
against the end of the mic (Fig. E3). Make certain the mic is
securely attached before use.
To detach the microphone, reverse the steps above.
Always
loosen the threaded collar
fully
before attempting to
disconnect the mic.
Latch
“CLICK”
The ATW-T102(x) provides a bias voltage of +5V on Pins 2
and 3 which will power some “battery/phantom” mics
designed to work at this low voltage. However, the
ATW-T102(x) will not power a “phantom powered” mic which
requires the more-typical 12 to 48 volts. Use of the bias
voltage will reduce battery life slightly. Presence of the bias
voltage will not affect dynamic microphones.
Pin 1 Case Ground
Pin 2 Audio “+” and 5V DC bias
Pin 3 Audio “–” and 5V DC bias
Transmitting Antenna
The ATW-T102(x) plug-on transmitter's antenna is housed in a
non-metallic section between the metal transmitter case and
the mic connector. For best operation, hold the body of the
microphone itself and do not cover or obstruct the antenna
area.
System Operation
Setting Channels
Use the provided screwdriver to set the channel selector
switches on the receiver and transmitter to the same
frequency (Fig. A/C/D).
As an example using a non-”x” unit, setting the X10 selector
on “5” and the X1 selector on “2” designates channel 52,
operating at 734.625 MHz as shown on the chart on page 9.
(With an “x” unit, channel 52 is 662.625 MHz, as shown on
page 10.)
Be certain the units are turned off when making
frequency changes.
Receiver On . . .
Turn down the output level of the receiver (OUT LEVEL) and
the input level control of the camera or mixer.
Turn the receiver on, choosing either “INT” (internal battery)
or “EXT” (external DC source) as appropriate. The power
indicator LED (PWR) will light up strongly with fresh batteries.
(If the LED becomes dim or extinguished, the batteries are
weak and should be replaced immediately for reliable
operation.)
If the tuner operation indicator LEDs (A and B) flicker, there
may be RF interference. If this occurs, select another
frequency. (Always turn the receiver off when making
frequency changes.)
Transmitter On . . .
Before turning on the transmitter, be certain the transmitter
channel selector switches are set to the same numbers as
those on the receiver.
Turn the transmitter on.
The transmitter has a three-position power switch. When
the switch is set to “Standby,” (“ST.BY”/”STAND BY”) the
transmitter produces RF with no audio signal. When the
switch is “On,” the transmitter produces both RF and audio.
With the switch “Off,” there is minimum noise output from
the receiver due to a special A-T muting system.
Setting Mic Levels
CAUTION! Adjust the Mic Level control
carefully
. Unlike the
Channel Selector switches, it will
not
rotate continuously!
The microphone input accommodates a wide range of mics
with typical sensitivity ratings of 1.5 mV (–56 dBV) to 15 mV
(–36 dBV) at 1 Pascal/94 dB SPL, while providing excellent
signal-to-noise ratios and maximum-acoustic-input levels.
1. Plug in the mic and power up the system.
2. Set the Mic Level control to the full clockwise (Hi) position.
Speak/sing into the microphone at typically-loud levels
while watching the Peak indicator on the receiver. If the
Peak indicator lights, turn the Mic Level control down
(counter-clockwise) only to the point where the indicator
light no longer illuminates. (When the AF Peak indicator
lights, the transmitter audio level is driving the receiver
into distortion. For best audio, the Mic Level should be
set as high as possible, but not so high as to light the
Peak indicator.)
3. Now, while speaking/singing into the microphone at
typically-loud levels, adjust the output level of the receiver
so the highest sound pressure level going into the
microphone causes no input overload in the camera/mixer,
and yet permits the camera/mixer level controls to operate
in their “normal” range (not set too high or too low). This
provides the optimum signal-to-noise for the entire system.
Setting Line Level – ATW-T101(x)
When using a Hi-Z line-level source with the ATW-T101(x)
transmitter, set the input level using the same method given
above. The Mic Level (MIC LVL) control adjusts audio gain for
both mic and line inputs.
RF Interference
Please note that wireless frequencies are shared with other
radio services. According to Federal Communications
Commission regulations, “Wireless microphone operations
are unprotected from interference from other licensed
operations in the band. If any interference is received by any
Government or non-Government operation, the wireless
microphone must cease operation . . .”
If you need assistance with operation or frequency selection,
please contact your dealer or the Audio-Technica professional
division.
Extensive wireless information also is available on the
Audio-Technica Web site at www.audio-technica.com.

Ten Tips To Obtain The Best Results
1. Use only fresh alkaline batteries; replace the receiver
batteries in pairs. Do not use “general purpose” (carbon-
zinc) batteries.
2. Position the receiver so that it has the fewest possible
obstructions between it and the normal location of the
transmitter. Line-of-sight is best.
3. The transmitter and the receiver should be as close
together as conveniently possible, but no closer together
than three feet.
4. The receiver antennas should be in the open and away
from any metal.
5. The transmitter and receiver must be set to the same
channel number. (Use “x” units together and non-”x”
units together.)
6. Only one transmitter on a given frequency should be
“on” at a time.
7. The power switch on the transmitter has three
positions: “Off,” “Standby,” and “On.” In the middle
“Standby” position, the transmitter sends only RF to
the receiver; the audio source is turned off.
8. If the “Out Level” of the receiver is set too high, it
may over-drive the input of the camera/mixer or clip
the output of the receiver, causing distortion.
Conversely, if the receiver output is set too low, the
overall signal-to-noise ratio of the system may be
reduced.
9. You need to change channels 1) when a strong
interference signal is received, 2) when the channel
breaks down, or 3) during multiple-system operation in
order to select an interference-free channel. Always
turn the units off before changing frequencies.
10. Turn the receiver and transmitter off when not in use.
Remove the batteries during long-term storage.
