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. -
