AC 220V 1050W

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.

Bridge Mode：

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

Binding Post Connector

Stereo/Parallel Mode:

Channel 1 red (+) / black (-) Binding posts are connected respectively to the positive (+) /

negative (-) terminals of speaker 1.

Channel 2 red (+) / black (-) Binding posts are connected respectively to the positive (+) /

negative (-) terminals of speaker 1.

Bridged Mode:

Channel 1 red (+) Binding post connected to the positive (+) terminals of speaker and

Channel 2 black(-) Binding post connected to the negative(-) terminals of spaker.

7.Fan Outlet

The fan draws air from the chassis.

8.Input Sensitivity Switch

0.775V( 0dBu) / 1V( 0dBv) / 32dB Threes input gain choices.

9.Working Mode Switch

1.Stereo: CH1-2 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.

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.

Earthing Switch

10.

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.

Note: The output of all amplifiers will produce high voltage. Live installation is not allowed. There shouldn't be any

excess bare copper exposed between the speaker cable and the amplifier binding posts. In addition, please do

not ground the amplifier output, or access to any other amplifier input or output. Please use high-quality speaker

connector and speakers dedicated cable, and minimize the power amplifier and speaker connection cable.
