Product Details

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

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.
