Creating a System

The A1260 provides plenty of power to create a great whole-house system,but it does not provide source selection and volume control. Therefore, a matrix controller, such as the A4603, is needed to unlock the full potential of the A1260.

• The A4603/A4603R… is a 4-input 6-output matrix A/ controller designed for whole-house audio systems.
• The unit is organized into 4 audio/video inputs and 6 audio/video outputs.
• The A4603 is intended to be used with a multichannel audio amplifier, such as the A1260.
• Any of the 4 source inputs can be selected and routed to any of the 6 outputs (or zones) independent of the other zones through the use of an IR repeating keypad (such as the A0127- Sold separately).
• The A4603R is equipped with a rack mount faceplate to allow installations in a standard 19″ equipment rack.

Control of the A4603… is accomplished through the use of an IR repeating device, such as the A0127 keypad. The A0127 already contains the IR codes necessary to operate the A4603, but you may also use a standard IR receiver such as the IR-2400 or a 3rd party keypad. When using a simple IR receiver, you will need to program a learning remote control with the IR codes for the A4603. These codes can be downloaded from www.channelvision.com, or learned from an A0127.
