The Audio-Technica ATW-3131b is a frequency agile, true-diversity wireless lavalier microphone system which is part of the 3000 Series. It is designed to provide reliable, professional UHF technology for the most demanding audio applications. The system includes the ATW-R310b receiver, ATW-T310b UniPak Transmitter, and AT831cW Cardioid Lavalier Microphone.
The ATW-R310b Receiver features frequency adjustable UHF reception, allowing access of up to 200 user-selectable channels. Diversity reception allows 2 built-in, independent receivers to rely on a single frequency for the strongest possible reception. The rear panel includes both unbalanced 1/4" phone and balanced XLR outputs. A comprehensive back-lit LCD display on the front panel reveals channel and frequency settings, signal status, and transmitter battery status. The receiver also features a ground lift switch, convenient in settings where bad power feeds result in ground hum and noise on the output stage.
The ATW-T310b Bodypack Transmitter features Audio-Technica's unique UniPak input connector. The input conveniently accepts both line and microphone level signals (adjustable) allowing it to be used for both instruments and microphones. The system includes the AT831cW Cardioid Lavalier Microphone, and an assortment of compatible microphones and instrument cables are also available separately from Audio-Technica. This lightweight transmitter operates on 2 AA Alkaline batteries for up to 6 hours (High) and 8 hours (Low).
The system operates on UHF frequencies allowing greater channel selectability and range. The transmitter and receiver feature 200 user-selectable channels.
The ATW-R310b receiver features dual internal receivers. The receivers relay between each-other, vying for the strongest reception while minimizing noise and signal drop-out.
Audio-Technica's UniPak transmitter is a bodypack with an input connection designed for low and high impedance signal. This makes the transmitter versatile enough to handle microphone and line level signals.
