Audio Technica MCB4 Audio-Technica MCB4 Antenna Combiner

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 (centre positive) to power as many as four transmitters operating on 12 volts at up to 600 mA each. Included with the unit are four DC cables appropriate for use with M3T (or like-powered) transmitters. The 12-volt supplies for powering transmitters are short-circuit protected. The unit features all-metal construction for extreme durability and protection from radio frequency interference.

This wireless monitoring set's receiver uses adaptive-diversity technology. The earphone cable serves as a second antenna, which considerably reduces the number of drop-outs. Combined with IE 4 ear-canal phones for precise sound reproduction, EK 2000 IEM conveys an authentic acoustic pattern of live sound and allows you to monitor your own performance perfectly.

The M3R belt pack receiver is part of the M3 system. Rugged, ergonomic compensate housing includes a field-replaceable flexible-whip antennas. Digital LCD display with soft touch controls. The stereo monitor system offers Personal Mix Control, which gives each musician volume and mix control of two independent signals on stage, via easy-to-use controls on the M2R stereo body-pack receiver. Any number of M2R stereo receivers may be used on the same frequency with a single M2T stereo transmitter. On board 3 level limiter (defeatable) helps protect your hearing from sudden peaks. Includes Audio-Technica earphones with proprietary dynamic drivers offer full frequency response and outstanding isolation with 3 sizes of rubber eartips plus an ear-conforming foam tip. Also, an auxiliary input offers a connection point for an ambient microphone, click track, or other mic- or line-level input.

These rugged systems are built to stand up to the inevitable bumps of life on the road, delivering clear, natural sound for touring and installed-sound uses.

The ATW-T310b wireless UniPak® body-pack transmitter has both low and high impedance inputs plus a 5V DC bian connection allowing it to be used with condenser and dynamic microphones, as well as Hi-Z instrument pickups. The locking 4-pin HRS-type audio input connector is recessed to protect the connection from damage. Operating on two standard AA batteries, the transmitter features high and low-level RF output settings. The low-level setting allows two additional hours of bttery life while retaining a strong RF signal link. Soft-touch controls provide convenient access to a variety of functions including: RF power, audio input level, power/mute locks and frequency selection. Each transmitterʼs backlit LCD display presents a great deal of setup and operating information clearly and conveniently including battery fuel remaining, mute, and operating frequency. A flashing "Lo-Batt” alert visually signals the battery life is almost depleted. A dual-colour status LED illuminates green when power is on, and red when the transmitter is muted. Programmable power/mute locks limit the functioning of the transmitterʼs power/mute button as desired for particular users and applications. To match the audio input level to the transmitter, a four-position audio input gain setting selected through the function menu is provided.

The body-pack transmitter features a safety cover to protect the soft-touch controls from being accidentally activated and a recessed input connector to increase the life of the microphone cable. Constructed of high impact materials, the body-pack transmitter features a field replaceable whip antenna and captive locking battery cover door.
