Channel Vision’s A4623 is a 4-Input, 6-Zone Amplified A/V System designed for whole-house audio/video distribution. The system provides both an amplified 20 Watt speaker output and a pre-amp output for each of the 6-zones making it easier to add a high powered amplifier for more demanding applications. Any of the 4-source inputs can be selected and routed to any of the 6-outputs (or zones) independent of the other zones. Now supports IR & RS-232 for touch screen integration and status feedback.
