Audio-Technica ATW-3131b 3000 Series Lavalier Wireless System

Audio-Technica


A frequency-agile True Diversity UHF wireless receiver with bodypack transmitter and lav mic.




The Audio-Technica ATW-3131b Lavalier Wireless
System is part of Audio-Technica's third-generation 3000 Series wireless
systems. It includes an Audio-Technica ATW-R3100b receiver, ATW-T310b
UniPak transmitter, and an Audio-Technica AT831cW lavalier microphone.
The wireless system offers 996 selectable UHF frequencies and features
for clear sound and intuitive operation.

Audio-Technica has
simplified the selection of usable frequencies, increased system
reliability, and illuminated transmitter screens for clear reads on dark
stages. It all adds up to the luxury of rock-solid, richly detailed
high-fidelity sound.

The versatile Audio-Technica ATW-T310b
UniPak body-pack transmitter features a secure 4-pin locking connector
compatible with a wide range of microphones, as well as a guitar cable. A
3-position sliding cover on the transmitter's control panel prevents
accidental shut-off or channel-switching. A locking battery compartment
provides a more secure latch and more robust design.

The
Audio-Technica ATW-R3100b receiver is equipped with automatic frequency
scanning for easy setup. It also features true diversity reception. Two
antennas feed two completely independent RF sections on the same
frequency; automatic logic circuitry continuously compares and selects
the superior received signal, providing better sound quality and
reducing the possibility of interference and dropouts. Soft-touch
controls provide convenient access to a variety of functions, while a
backlit LCD information display provides constant monitoring of system
operation, including indication of the transmitter's battery status. The
receiver is half-width for a standard 1U 19" rack mount; rack-mount
adapters are included.

An advanced Digital Tone Lock tone
squelch system in the ATW-R3100b receiver opens only when a 3000 Series
transmitter 3000 Series Installation and Operation is detected, reducing
the possibility of interference. As a result, 3000 Series transmitters
and receivers must be used together and should not be used with
components from other Audio-Technica wireless systems, or with those of
other manufacturers. Exception: 3000 Series components are compatible
with Audio-Technica 1800 Series wireless system components.

AT831cW
lavalier microphone is a cardioid condenser mic terminated with locking
4-pin connector designed speciifcally for the A-T UniPak body-pack
wireless transmitters. It features a 55" (1.4m) cable and Includes a
windscreen and clothing clip.
