Main Operation Button And Function
Rear Panel
1. Power ON/OFF Switch
When press this button, the prevent wave shock current shall start and
soft boot up, after 3-4 seconds, you can hear the relay holding ("Ca Ca"
noise). The soft boot up finish, then after 1-2 second too, the double
noise can heard once time, the amplifier already connect the speaker,
now this equipment in stand by status.
2. CH B input level adjust knob
You can use this knob to adjust volume according your need, also you
can accord the graduation of front panel to adjust when position far from
speaker.
3. CH B / CH A protect LED (RED)
it will be light-up in 3 kind status
1. At 4-6 second after power on, the amplifier now booting to stand
by status, it still haven't connect to the speaker, to avoid high current
shock to the speaker.
2. Over 85° C of the power parts cover
3. the amplifier work un-normally, centre-voltage move to
unbalance
4. CH A input level adjust knob
The adjustment is same than CH B, only using this knob when the
amplifier in bridge model
5. Clip indication LED (yellow)
6. SIGNAL indication LED (green)
7. LCD Dispaly
1. Air ventilation slots: Do not block
2. Ch B speak-on output socket
To connect a speaker with minimum impedance of 2 Ohm. The way of connecting is 1+ ; 1-.
3. MONO speak-on output socket
To connect a speaker with minimum impedance of 4 Ohm. The way of connecting is 1+ ; 1-.
4. Ch A speak-on output socket
To connect a speaker with minimum impedance of 2 Ohm. The way of connecting is 1+ ; 1-.
5. Balanced XLR input signal
6. Balanced XLR signal link output
7. Cross-Over switch:
By pass: 20-20.000 Hz
High Pass: 120-20.000 Hz
Low Pass: 20-120 Hz
8. Input Sensitivity Selector: 0.77 - 1.0 - 1.41 V
9. Limiter on/off
This feature help to protect your amplifier and speakers against input signals that are too high. When
the limiter function is switched on and the input signal too high the amplifier will automatically reduce
the input gain. This is as safety feature an does not permit misuse or abuse of the amplifier
10. Ground lift switch
Setting tubs switch to ground and lift, you can break the ground loop between the amplifier and the
chassis grounds of various components. The resistor is 100 K Ohm
11. Selector switch operating mode
Position STE: stereo operation;
Position BRI: bridge operation (input signal in Ch A)
12. Power cord receptacle
Use only the supplied power cord or suitable replacement.
13. Main inlet fuse
When occurs a problem on this appliance the fuse is cut off power to prevent form a problem, to
Position PAR: both channles on input signal in Ch A
