Nady UHF4 Headset Wireless System

The Nady UHF-4 systems offer unprecedented value in a full-featured single-channel UHF wireless mic system -- with interference-free operation in any application or locale on select UHF frequencies from 794 to 865 Mhz.

Features
Half-rack receiver design with folding front panel dual antennas and unique snap-out panel locking tabs for single receiver or dual receiver (side-by-side)optional rack mounting

Nady's proprietary companding circuitry for an industry best 120dB dynamic range, and the clearest, most natural sound available

Tone Squelch for locking out potential interference

UHF-4 receiver with DigiTRU diversity for maximum range and dropout protection, full LED indicators, both 1/4 in. unbalanced and XLR balanced outputs, and special circuitry for noiseless transmitter on/off switching

UB-4 Bodypack Transmitter
Choice of instrument or headworn/lavalier microphone bodypack transmitter in a single unit -- off/standby/on switch allows convenient audio muting with the transmitter "on"

Status LED indicator flashes once for unit "on"; lights steady for low battery alert

Locking 3.5mm mini-jack provides secure connection for removable microphone or instrument cable

9V alkaline or NiMH battery operation

Does NOT include the handheld shown. Has HM3 instead.
