Simplifies and centralizes multiple transmitter setups.

The Audio-Technica MCB4 Antenna Combiner is designed to combine the signals from up to 4 Audio-Technica M3 Wireless In-Ear Monitor stereo transmitters onto a single transmitting antenna. The result: reduced clutter in your rack and increased savings for you.

The Audio-Technica MCB4 antenna combiner's wide-band unit operates over the 440-865MHz range. Though it is designed to complement Audio-Technica M3 Wireless In-Ear Monitor Systems, the M84 active antenna combiner is also suitable for many other in-ear wireless systems (with external BNC antenna connections) operating within the 440 to 865 MHz range. Audio-Technica equips the MCB4 1 antenna combiner with 1 output and 4 isolated transmitter inputs. All RF connectors are BNC-type.

Four jacks on the rear panel (controlled by the M84 unit's power switch) provide 12V DC (center positive) to power as many as 4 wireless microphne transmitters operating on 12 volts at up to 600mA each. Included with the Audio-Technica M84 antenna combiner are 4 DC cables appropriate for use with M3T (or like-powered) wireless transmitters. Audio-Technica built short-circuit protection into the 12-volt transmitter's power supplies. The Audio-Technica MCB4 active antenna combiner's all-metal construction contributes to extreme durability and protection from radio frequency interference.

  • Broadband UHF operation (440-865MHz range)
  • Combines the signals of up to four wireless in-ear monitor transmitters into one antenna
  • Centralized power supply with ability to power four individual transmitters
  • Maintains clean signals with low distortion
  • Includes hardware for front-mounting the antenna for improved performance
