Consumer Alert - Most users do not need a license to operate this wireless
microphone system. Nevertheless, operating this microphone system without a license
is subject to certain restrictions: the system may not cause harmful interference;
it must operate at a low power level (not in excess of 50 milliwatts); and it has
no protection from interference received from any other device. Purchasers should
also be aware that the FCC is currently evaluating use of wireless microphone systems,
and these rules are subject to change. For more information, call the FCC at 1-888-CALL-FCC
(TTY: 1-888-TELL-FCC) or visit the FCC�s wireless microphone website at http://www.fcc.gov/cgb/wirelessmicrophones.

Audio-Technica MCB4 Active Antenna Combiner
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.
