Audio-Technica ATW-3131b Wireless Lavalier System
The ATW-3131b is the lavalier configuration of Audio-Technica's third-generation 3000 Series, a frequency-agile true-diversity UHF wireless system for stage, worship, and presentation. It pairs the ATW-R3100 receiver with the ATW-T310 UniPak body-pack transmitter and an AT831cW cardioid lavalier microphone. True-diversity reception compares two independent RF circuits to hold a solid link across the room.
The system tunes across the band with up to 1001 selectable frequencies at 25 kHz spacing, and automatic frequency scanning with pre-coordinated scan groups finds clear channels in busy RF. It ships in three band options: C (541.500-566.375 MHz, TV 25-30), D (655.500-680.375 MHz, TV 44-49), and I (482.000-507.000 MHz, TV 16-20). Rack-mount hardware for the receiver is included.
