H Series

1. Mains Power Switch When pressing the switch, the soft-start circuit runs for avoiding surge strike. In about 3-4 seconds, there will be a clicking denoting that the soft-start is finished. And more 1-2 seconds later, there will be another “clicking”, the amplifier is connected with the speaker and ready to work.

2. CH-1/CH-2 Input level control Adjust it to get the volume desired. Use CH-1 control only while the amplifier is set in Bridge or Parallel mode.

3. Signal LED The green signal led indicates that a music signal is present at this channel input.

4.CH-1/CH-2 Protection indicating LED This red LED will light up when the amplifier is running unstable or went into thermal protection after the power elements temperature is over 90℃.

5. Clip LED Turns on just before the maximum, distortion-free, output level of the amplifier. The clip LEDs may turn on shortly from time to time but they may certainly not turn on for longer periods. In this case, you have to turn the output level down!

6. Bridge mode indicating LED Indicate the amplifier is working under BRIDGE mode, the indicator is lightened, and the input signal only acts on CH-1

7. Mono mode indicating LED Indicate that the amplifier is working under the mono mode, the indicator is lightened, input signal only acts on CH-1.

8. Stereo mode indicating LED These green LED will light up while the input signal is connected, the amplifier is working under stereo mode.

1. MAINS POWER SUPPLY CORD

2.CH-1/CH-2 SPEAKON OUTPUT Used by a standard SPEAKON connector.

3.CH-1/CH-2 BINDING POST OUTPUT Used by a standard binding connector.

4. OUTPUT MODE SET SWITCH. BRIDGE MONO MODE. Sends CH-1 signals out-of-phase to CH-2, producing twice the normal voltage swing between the two RED speaker terminals (CH-1 RED is defined as positive). Only CH-1 controls and input are effective. STEREO MODE. Each channel operates independently. as usual. MONO INPUT MODE. Sends CH-1 signals out CH-2, Only CH 1 controls and input are effective. NOTE: speaker connections work, as usual, Never connect the red output terminals directly together.

5. CH-1/CH-2 XLR INPUT CONNECTOR Standard XLR (male) socket for input signal link. Pin1: signal ground, Pin2: signal+, Pin3: signal-

6. CH-1/CH-2 XLR OUTPUT CONNECTOR
