New York (January 22, 2010)–Audio-Technica debuted its new MCB4 IEM Antenna Combiner at NAMM. The MCB4 allows the signals of up to four A-T M3 Wireless In-Ear Monitor stereo transmitters to be combined onto a single transmitting antenna.
A wide-band unit that operates over a nominal 470-865 MHz range, the MCB4 is designed to complement Audio-Technica M3 Wireless In-Ear Monitor Systems, and is reportedly also suitable for other in-ear wireless systems (with external BNC antenna connections). The MCB4 provides one output and four isolated transmitter inputs. All RF connectors are BNC-type. Passive antennas may be used.
Four jacks on the rear panel (controlled by the unit’s power switch) provide 12V DC (center positive) to power as many as four transmitters operating on 12 volts at up to 500 mA each. Included with the unit are four DC cables appropriate for use with A-T’s M3T stereo transmitter or like-powered transmitters from other manufacturers. The 12-volt supplies for powering transmitters are short-circuit protected, and the unit features all-metal construction for durability and protection from RF interference.
Audio-Technica’s MCB4 IEM Antenna Combiner will be available Spring 2010 with a U.S. MSRP of $799.00.
