ATW-T702 HandheldTransmitter

CAUTION! The small trimmer controls are delicate; use only

the supplied screwdriver. Do not force the trimmers beyond

their normal 180° range of rotation.

Return the screwdriver to its storage clip when not in use.

ATW-T701 UniPak

Transmitter

Trim controls in the UniPak transmitter (Fig. I) will enable you to

use microphones or instruments with different output levels.

1. For MIC: Set MIC (microphone trim) control fully clockwise

(maximum) and INST (instrument trim) control fully counter

clockwise (low).

For INSTRUMENT: Set INST (instrument trim) control fully

clockwise (maximum) and MIC (microphone trim) control

fully counterclockwise (low).

2. Set the receiver's AF Level control to its full clockwise

position (maximum). (Fig. C on page 4).

3. Plug the mic or instrument into the transmitter and power

up the system.

4. For MIC: Make an initial adjustment of the mixer's level

controls that will allow audio through the system.

For INSTRUMENT: Make an initial adjustment of the

instrument amplifier input level control that will allow audio

through the system.

5. For MIC: While speaking/singing into the microphone at

typically loud levels, check the AF peak indicator on the

receiver. If AF peak indicator is easily illuminated and

distortion is heard through the system, it may be necessary

to adjust the transmitter audio input level. To adjust the

transmitter audio input level, gently

turn the microphone

trim control counterclockwise until the AF peak indicator is

illuminated only on audio peaks.

For INSTRUMENT: While playing the instrument at typically

loud levels, check the AF peak indicator on the receiver. If

AF peak indicator is easily illuminated and distortion is heard

through the system, it may be necessary to adjust the

transmitter audio input level. To adjust the transmitter audio

input level, gently

turn the instrument trim control

counterclockwise until the AF peak indicator is illuminated

only on audio peaks.

. For MIC: While again speaking/singing into the microphone

at typically loud levels, adjust the mixer's input trim control

so the highest sound pressure level going into the

microphone causes no input overload in the mixer, and yet

permits the mixer's channel and output level controls to

operate in their “normal” range (not set too high or too low).

For INSTRUMENT: While again playing the instrument at

typically loud levels, adjust the receiver's AF Level control

so the highest signal level causes no input overload in the

nstrument amplifier and yet permits the amplifier's input

level controls to operate in their “normal” range (not set too

high or too low).

Note: If the mixer cannot be adjusted to operate in its normal

range without distortion, adjust the receiver's AF Level Control

(turn counterclockwise) until the mixer/amplifier is no longer

overloaded.

Note: RF power may be set to high or low via the RF power

select switch on the side of the UniPak transmitter. (Fig. I.)

While the high setting normally provides maximum operating

range, the low setting will help extend battery life. The low

setting may also be preferred in multi-channel systems, or when

operating very close to the receiver, to reduce the

possibility of interference or overload.

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

Audio-Technica. Extensive wireless information is also available

on the Audio-Technica Web site at www.audio-technica.com.
