The ABUS-MS1 4-Source Input Module provides stereo audio and IR control connectivity from your system components to the ABUS-HUB1X4 distribution hub. This module features four sets of stereo RCA inputs with loop-outs for DVD/CD player, cable boxes, amplifier, etc., RJ-45 jack for hub communication, and a 12V-Trigger output for power switching. It features IR emitter outputs to transmit infrared commands to concealed components. With this option you can finally close your entertainment doors, conceal your system components and their messy wires, and still maintain full control.

Four Stereo Audio Inputs
It includes four sets RCA stereo audio inputs that accept the audio output from the main amplifier and other system components. Each input has individual loop outputs capable of sending the desired audio signal on to the next component without loss or gain.
A-BUS Connectivity
This module uses a standard RJ-45 jack to connect to expansion input port of the ABUS-HUB1X4.
Four IR Outputs
Its four IR emitter outputs enable control of connected source components.
2nd-Zone Output
This unit may be used in conjunction with a main system amplifier, to provide an independent 2nd zone for the ABUS system that has access to as many as four sources.
Main System Input Selector
The input selector enables the A-BUS system to operate independently by providing inputs for switching up to four source components.
Auto Sensing
Auto turn-on when local audio signal is sensed, and auto return 30 seconds after audio ceases.
Remote Operation
Inputs are selected via the ABR-40 remote control. It features four input selections, two "OFF" buttons, and offers the ability to power up the A-BUS system if it's on standby.
