A True-Diversity UHF wireless receiver with cardioid handheld mic/transmitter.

The ATW-3171b Wireless Dynamic Microphone System is part of Audio-Technica's third-generation 3000 Series. It includes an Audio-Technica ATW-R3100b receiver and an Audio-Technica ATW-T371b handheld cardioid condenser microphone/transmitter.

The wireless system offers 996 selectable UHF frequencies and features for clear sound and intuitive operation. Audio-Technica has simplified the 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 Audio-Technica ATW-R3100b receiver is equipped with automatic frequency scanning for easy setup. It also features true diversity reception. Two antennas feed two completely independent RF sections on the same frequency; automatic logic circuitry continuously compares and selects the superior received signal, providing better sound quality and reducing the possibility of interference and dropouts. Soft-touch controls provide convenient access to a variety of functions, while a backlit LCD information display provides constant monitoring of system operation, including indication of the transmitter's battery status. The receiver is half-width for a standard 1U 19" rack mount; rack-mount adapters are included.

The Audio-Technica ATW-T341b handheld dynamic microphone/transmitter features the same element used in the Artist Elite AE4100 dynamic handheld microphone created for professional live sound venues. This transmitter uses two 1.5V AA batteries for economical operation and wide availability, and has a "fuel gauge" battery condition indicators with low-battery warnings.

An advanced Digital Tone Lock tone squelch system in the ATW-R3100b receiver opens only when a 3000 Series transmitter 3000 Series Installation and Operation is detected, reducing the possibility of interference. As a result, 3000 Series transmitters and receivers must be used together and should not be used with components from other Audio-Technica wireless systems, or with those of other manufacturers. Exception: 3000 Series components are compatible with Audio-Technica 1800 Series wireless system components.
