1.Thermal Breaker

The power amplifier will disconnect the AC power supply in the event of an overload condition.

Pressing the reset lever after the fault is released, it will restore the operation (reusable).

2.Power Cable

Plug into AC power socket.

3.Signal In LINK

LINK Input Connector(Pin 1=Ground/Pin 2=+/Pin 3=- ).

4.Signal In

XLR Input Connector:

1) Balance input: Pin 1=Ground/Pin 2=+/Pin 3=- (according to standard IEC 268)

2) un-balance input: Pin 1/3=Ground/Pin 2=+

5.Speakon Output Connector

Stereo/Parallel Mode:

Speakon1 1 + / 1 - Respectively Connect the positive (+) / negative (-) terminals of speaker 1.

Speakon1 2 + / 2 - Respectively Connect the positive (+) / negative (-) terminals of speaker 2.

Speakon2 1 + / 1 - Respectively Connect the positive (+) / negative (-) terminals of speaker 2.

Speakon2 2 + / 2 - Idle.

Speakon3 1 + / 1 - Respectively Connect the positive (+) / negative (-) terminals of speaker 3.

Speakon3 2 + / 2 - Respectively Connect the positive (+) / negative (-) terminals of speaker 4.

Speakon41 + / 1 - Respectively Connect the positive (+) / negative (-) terminals of speaker 4.

Speakon4 2 + / 2 - Idle.

Bridge Mode：

Speakon1 1 + / 2- Respectively Connect the positive (+) / negative (-) terminals of speaker 2.

Speakon3 1 + / 2- Respectively Connect the positive (+) / negative (-) terminals of speaker 2.

6.Input Sensitivity Switch

0. 775V（0dBu）/1V（0dBv）/32dB Three input gain choices.

7.Working Mode Switch

1.Stereo: CH1-4 Function Independent work and control.

2. Parallel: 1)Input signal to CH1, CH1 is paralleled with CH2, CH1 and CH2 are controlled

independently, now CH2 input is invalid.

2)Input signal to CH3, CH3 is paralleled with CH4, CH3 and CH4 are controlled

independently, now CH4 input is invalid.

3. Bridged: 1) Input signal to CH1, signal through CH1 will access CH2 in reverse phase,

The volume of CH1 can control CH2 at the same time. CH1 Output and CH2

Output connect with Speaker in series.

2)Input signal to CH3, signal through CH3 will access CH4 in reverse phase,

The volume of CH3 can control CH4 at the same time. CH3 Output and CH4

Output connect with Speaker in series.

8.Earthing Switch

When the switch is turned ON (AC ground), the ground switch is on (AC-DC ground), signal ground

selection --- The audio system noise can be suppressed by grounding switch.
