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.

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.

Audio-Technicaʼs System 10 Stompbox digital high-fidelity guitar wireless system combines the advanced 24-bit operation, easy setup and clear, natural sound quality of other System 10 configurations with unique functionality for guitarists, bassists and other instrumentalists. Operating in the 2.4 GHz range, far from TV and DTV interference, System 10 Stompbox offers a rugged, metal, pedal board-mountable receiver with foot switch, two switched TRS balanced 1/4" outputs and an output mode selector. With the tap of a foot, musicians can toggle between outputs (e.g., for switching amps) or mute and unmute one output without muting the other (e.g., for convenient tuning). And a single receiver can be paired with up to eight UniPak® body-pack transmitters, allowing users to easily switch between instruments without having to move a body-pack from one instrument to the next.

System 10 wireless ensures clear communications by providing three levels of diversity assurance: frequency, time, and space. Frequency Diversity sends the signal on two dynamically allocated frequencies for interference-free communication. Time Diversity sends the signal in multiple time slots to maximize immunity to multipath interference. Finally, Space Diversity uses two antennas on each transmitter and receiver to maximize signal integrity.

Each Stompbox system includes an ATW-R1500 Stompbox receiver, an ATW-T1001 UniPak body-pack transmitter with an AT-GcW guitar cable, and hook & loop strips for adding receiver to an effects pedal board. The ATW-R1500 is a digital receiver with sturdy, metal-body construction, easy-to-read digital ID and transmitter battery level displays, and AF Peak and Pair indicator lights.
