The black ATW-3194b Headworn Wireless System from Audio-Technica includes the ATW-R3100b receiver, an ATW-T310b UniPak transmitter, a BP894cW headworn cardioid condenser microphone, a windscreen, and a clothing clip. It can be used in a variety of live sound applications that require a headworn microphone. It is tuned to Audio-Technica's D band between 655.500 and 680.375 MHz.
The system employs both true diversity reception and Audio-Technica's Tone Lock squelch system to provide interference-free performance. It features 1,001 frequencies that can be selected from automatically thanks to the system's automatic frequency scan
Audio-Technica ATW-R3100bD True Diversity UHF Wireless Receiver
The Audio-Technica ATW-R3100bD True Diversity UHF Wireless Receiver is used in the Audio-Technica 3000 series wireless microphone systems. It features Automatic Frequency Scanning, which selects the best available frequency. True Diversity means that the ATW-R3100bD has two independent receiver sections, and automatically sends the strongest signal of the two to the output at any given moment, greatly reducing the possibility of dropouts.
Other features include nine pre-coordinated frequency scan groups to simplify channel selection in a multi-channel system; a high-efficiency compander; 25 kHz frequency spacing, which makes it easier to find open channels in crowded frequency bands; DigitalTone Lock Squelch and Adjustable Receiver Squelch to help keep background noise suppressed when the intended signal isn't present; and a transmitter battery life gauge.
Among the rear-panel offerings are unbalanced 1/4" TS and balanced XLR outputs, and an output level control. The back-lit LCD display reveals channel and frequency settings, signal status and transmitter battery status. The receiver also offers a ground lift switch, convenient in situations where bad power feeds result in ground hum and noise on the output stage.
Band C: 541.500-566.375 MHz (ATW-R3100bC)
Band I: 482.000-507.000 MHz (ATW-R3100bI)
Audio-Technica ATW-T310B Wireless Bodypack Transmitter
