The WTU-M9800 tuner may be used in any TOA mixer that accepts a 900 series module. Each module is a diversity UHF receiver with 16 user selectable frequencies. Up to two modules may be used in a frame without the use of an external power supply. A wide range of M band transmitters is available, as all 5000 series microphones and belt packs are compatible with WTU-M9800. Two whip antennas on standard BNC connectors are included. Phantom power on the antenna inputs supports the use of TOA’s YW-4500 Q powered remote antennas.
