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:

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.
