Product Description
The ATW-702 is a system of the 700 Freeway series of Audio-Technica including the ATW-R700 receiver and the ATW-T702 unidirectional handheld microphone/transmitter with the Quiet-Flex stand clamp.
The ATW-T700 receiver is a compact unit with 8 selectable UHF automatic frequency scanning channels and two diversity switching antennas. This UHF, diversity combination leads to fewer drop outs. Balanced and unbalanced output connections on the rear panel give more flexibility to the receiver set.
The ATW-T702 transmitter is a strong built, light weight mic operated by 2 AA alkaline batteries that last up to 10 hours on Low mW mode. The cardioid polar pattern fitted on the capsule minimizes ambiance noise and feedback from nearby monitors or instruments. High sound pressure without distortion is handled by the dynamic element. A switchable output power to increase RF power when needed is provided in the ATW-T702.
