Wireless UHF Body pack Microphone System with AT831 cW Lavalier Microphone, Frequency-Agile, True Diversity, TV25-30
System Includes:
ATW-R3100b receiver
ATW-T310b UniPak Transmitter
AT831cW Lavalier Microphone
Audio-Technica's third-generation 3000 Series wireless systems offer up to 1001 selectable UHF frequencies and new features for clear sound & intuitive operation. AT has simplified 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 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 new locking battery compartment provides a more secure latch and more robust design.
AT831cW Cardioid Condenser Lavalier Microphone
This clip-on lavalier mic provides crisp, full-sounding voice pickup. The AT831cW also excels as an instrument mic, especially for pickup of acoustic guitar with included AT8444 guitar adapter. The mic is ideal for higher SPL applications. Excellent gain before feedback and suppression of background noise. Operates on phantom power only.
