Speaker Wiring Configurations

4Ω Load with 4Ω speakers:

4Ω Load with 8Ω Speakers:

PoC Connection

The system supports PoC, which allows several terminals share the same power supply and eliminates the need for extra power supply at the remote nodes.

Connect a 24V DC power adapter to the power port of receiver, the transmitter and control panel can be energized synchronously with PoC solution, see the picture below:

USB Connection
The receiver has a USB port (FROM TOUCH SCREEN) to connect interactive whiteboard. When user make notes on interactive whiteboard, the receiver will receive the signal from interactive whiteboard and send it back to the Host PC. Please refer to the return path of USB signal as shown as below.

Note: The special USB control cable is required if the connection distance is more than 4m/13ft between the receiver and the interactive whiteboard.

IR Connection

The control panel provides a built-in IR sensor and the receiver provides an IR OUT port for IR pass-through control. Connect IR emitter to the IR OUT port of the receiver, and then put the IR emitter close to the display device (e.g. Projector), and put the IR remote of display device close to the built-in IR sensor, the display device can be controlled by pressing IR remote.

RS232 Connection

The receiver provides an additional RS232 interface to connect the display device, and then the display device can be controlled by sending RS232 commands via GUI. Please refer to 5.3.3 Command Tab
