ATW-T1801 UniPak™ Body-pack Transmitter &
ATW-T1802 Plug-on Transmitter Controls
Antenna
The ATW-T1801 UniPak™ Body-pack Transmitter includes a field-replaceable 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 or try
repositioning the receiver. Since the transmitter antenna simply screws in, check to make certain it
is snugly attached (finger-tight). Do not change the length of the transmitting antenna.
Power-on LED
Green light indicates power is on and un-muted; red light indicates that audio is muted.
LCD Window
The Liquid Crystal Display presents setup and operating information clearly and conveniently). The
LCD in the transmitters is designed for greatest contrast and best viewing with the window rotated
somewhat away from the viewer (about 30 degrees), not straight-on, for a more convenient
holding/viewing position. The display is illuminated with a backlight when you press Set to access
transmitter functions. The backlight will automatically turn off within a set period of time.
Audio Input Jack
Connect an audio input device (microphone or guitar cable) to the audio input jack on the bottom of
the
ATW-T1801 UniPak™ Body-pack Transmitter. A number of Audio-Technica professional
microphones and cables are available separately, pre-terminated with a UniPak input connector
(see “Optional System Accessories” ). The cable connector latches automatically when inserted
into the transmitter jack. To unlatch and remove the connector, pull up on the connector’s knurled
metal collar.
Microphone Input
The ATW-T1802 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. Then rotate the collar back “up” one or two turns to expose the microphone
latch. Press the microphone and transmitter together , 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
