1001 Frequencies
Switchable Output Power

The Audio-Technica ATW-3110b Wireless Body-Pack System is a frequency agile, true-diversity system that includes the ATW-R310 receiver and ATW-T310 UniPak transmitter. The absence of a microphone allows users the freedom to choose any of the Audio-Technica UniPak compatible microphones or cables as desired.
The ATW-R310b receiver features frequency adjustable UHF reception, allowing access of up to 996 user selectable channels. Diversity reception allows 2 built-in independent receivers to relay on a single frequency for the strongest possible reception. The rear panel reveals both unbalanced 1/4" phone and balanced XLR outputs. A comprehensive back-lit LCD display 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 body-pack transmitter features Audio-Technica's unique UniPak input connector. The input conveniently accepts both line and microphone level signals (adjustable) allowing instrument signals as well as microphone signals. An assortment of compatible microphones and instrument cables are available from Audio-Technica. The lightweight transmitter operates on 2 AA alkaline batteries for up to 6 hours (High) and 8 hours (Low).
