GENERAL DESCRIPTION
The TOA WT-770 is a VHF high band tuner that permits simultaneous use of up to two optional
wireless tuner modules WTU-770 and WTU-771. To ensure its reliability, the WT-770 employs a
compressor/expander system noise reduction circuit to minimize the influence of hight-frequency
noise generated from digital equipment such as personal computers and word processors as well as
a combined noise/tone squelch circuit.
HANDLING PRECAUTIONS
Check for proper operating voltage of your tuner before use.
The model WT-770 "L" is intended for operation on 120V AC/60 Hz, and the WT-770 "H" for
220~240V AC/50 Hz.
When using a component rack, avoid installing the unit above heat generating equipment such as a
power amplifier.
To avoid severe electrical shocks and possible catastrophic damage, never open the unit nor touch
its internal components.
To clean the unit's exterior, wipe with a soft dry cloth. Never use benzine, thinner, or other solvents,
which may damage the painted parts of the unit.
FEATURES
A tone squelch prevents disturbing radio signals from producing noise when the wireless
microphone is not in use.
Modular construction facilities channel expansion and frequency changes.
Space-saving design and simultaneous dual channel operation.
Rack mountable. (Optional brackets required.)
Wide dynamic range and less susceptibility to high frequency noise in space thanks to a
compressor/expander circuit.
