Audio-Technica Unveils MCB4 IEM Antenna Combiner

Audio-Technica has introduced its MCB4 IEM Antenna Combiner, which allows the signals of up to four A-T M3 Wireless In-Ear Monitor stereo transmitters to be combined onto a single transmitting antenna, reducing rack clutter.

A wide-band unit that operates over a nominal 470-865 MHz range, the MCB4 is not only designed to complement Audio-Technica M3 Wireless In-Ear Monitor Systems, but it is also suitable for many 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 and 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.

Other features include Broadband UHF operation (470-865 MHz range), a Centralized power supply with ability to power four individual transmitters, hardware for front-mounted antenna for improved performance, and adapters to allow the unit to be mounted into a single rack space.

The MCB4 IEM Antenna Combiner will be available in the spring of 2010 with a MSRP of $799.00.
