GENERAL DESCRIPTION

Designed for virtual elimination of problem "null spots" or "dropouts" (momentary loss of radio signal reception), the TOA WT-870 is a diversity tuner that permits simultaneous use of up to two optional wireless tuner modules WTU-870 and WTU-871. To ensure its reliability, the WT-870 employs a compressor/expander system noise reduction circuit to minimize the influence of high-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-870 "L" is intended for operation on 120V AC/60 Hz, and the WT-870 "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

Diversity reception system minimizes the effects of fading during reception of a radio signal.

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/expandercircuit.
