Installation and Operation

POWER

The Audio-Technica MCB4 Antenna Combiner allows the signals of up to four 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 the 440-865 MHz range, the MCB4 is designed to complement Audio-Technica M3 Wireless In-Ear Monitor Systems. It is also suitable for many other in-ear wireless systems (with external BNC antenna connections) operating within the 440 to 865 MHz range.

The MCB4 provides one output and four isolated transmitter inputs. All RF connectors are BNC-type.

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 600 mA each. Included with the unit

Prior to use of this product, review all safety markings and instructions.

WARNING: This apparatus must be grounded.

This product is a safety class 1 product. There must be an uninterruptible safety earth ground from the main power source to the product’s AC input. Whenever it is likely that the protection has been impaired, disconnect the power cord until the ground has been restored.

ATTENTION: Cet appareil doit être mise à la terre.

Cet appareil est de classe de sûreté 1. Il doit y avoir un ininterrompable de mise à la terre de sécurité provenant de la source principale de courant de l’appareil de l’entrée du courant alternatif. Quand la protection a été affaiblie, débrancher le fil de courant jusqu’à la mise à terre a bien été réétablie.

Warning/Attention: To prevent fire or shock hazard, do not

expose this appliance to rain or moisture. Pour prévenir feu ou choc électrique, ne pas exposé l’appareil à la pluie ou à l’humidité.

The detachable IEC type power input cord supplied is intended for use in regions with mains voltage in the range of 100–125VAC only. Use only the furnished power cord that includes the appropriate NEMA 5-15P/ANSI C73.11 type attachment plug.

For use in geographical areas with mains voltage outside of the range 100–125VAC, it is necessary for the user to utilize a power cord rated and configured for operation in their region. Replace the supplied power cord with a cord rated for correct voltage operation.

1. Use the included BNC-to-BNC cables to connect the RF OUT of each M3T Transmitter to the INPUTS of the MCB4 Antenna Combiner.

2. Attach the antenna (one included with each M3T Transmitter), or an optional ATW-A49S directional antenna, to the ANTENNA FEED connector on the MCB4 Antenna Combiner.

3. If desired, connect the MCB4 DC OUTPUT to the DC INPUT of each M3T transmitter.

4. Plug the included desktop power supply of the MCB4 into the DC power input. The power supply is designed to operate properly from any AC power source 100-240V, 50/60 Hz without user adjustment. Simply connect the power supply to a standard AC power outlet.
