Multi-Source Audio Selector for the A-Bus System


Multi-Source Audio Selector for the A-Bus System
ABUS is a revolutionary new technology created to simply and affordably distribute music in commercial and home applications. ABUS works with inexpensive 8-conductor (CAT 5) wire to distribute audio, infrared, status and system power to the ABUS in-wall controller/amplifier.

Where there is no main system amplifier, the ABUS-MS1 Input Selector enables the A-BUS system to operate independently by providing inputs for switching up to four source components.

The selector's four stereo RCA-jack inputs accept audio line level signal from source components, such as tuners, CD players, DVD players, cable boxes, etc. Any of the Selector's inputs may be chosen via remote control commands. The four loop-outs will send the audio signal on to the next component without loss or gain.

There are four emitter ports to control source components if required, a 12-volt trigger output for power switching and an infrared pass-through to control other devices.

No separate power supply is required because the Input Selector is powered via it's connection to the A-BUS system. A standard RJ-45 patch lead (568A) is required between the A-BUS output and the expansion input port of an A-BUS hub. (ABUS-HUB1X4)
