ATW-R3100b receiver and ATW-T341b handheld cardioid dynamic microphone/transmitter.

Audio-Technica's third-generation 3000 Series wireless systems offer up to 1001 selectable UHF frequencies and new features for clear sound & intuitive operation. We've 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.

The 3000 Series is available with either a dynamic or condenser handheld transmitter featuring rugged metal construction and slim ergonomic design. The ATW-T341b handheld transmitter includes the stage-proven Artist Elite® AE4100 cardioid dynamic element, and the ATW-T371b handheld transmitter features the studio-quality Artist Series ATM710 cardioid condenser element.

Nine pre-coordinated frequency scan groups simplify selection of usable frequencies in a multi-channel wireless system
