Front panel:
1.
Power ON/OFF switch
Use to turn the amplifier on and off. Amplifier will be ready for operation in a few seconds after switched ON.
2.
CH-1/CH-2/CH-3/CH-4 input level control
Use to get desired input signal level.
3.
CH-1/CH-2/CH-3/CH-4 protection LED (yellow)
This LED will be illuminated when amplifier under below conditions:
A. Within 3-5 second after amplifier switched On or OFF.
B. The running temperature of the power elements inside the amplifier is over 85
C. The amplifier is in singularly failure.
4.
Led Bar for signal level indicating
The green ON led will be illuminated when the amplifier is turned on.
When amplifier volume exceeded maximum output level and a clipped signal already been sent to speakers, the red
PEAK led illuminated. Consistent lighting this led can cause both amplifier and speaker damaged.
5/6/7. MIX1-2, MIX2-3, MIX3-4 Input signal Link switch :
This 4 channel amplifier can be operated with maximum 4 independent input signals and by these input signal
switches, it can offers various operation modes, such as:
1 input signal & 4 outputs:
Input signal connect to CH-1 input socket, pressed all the input signal link switches. Now the amplifier can offer 4
outputs with same input signal and the input signal level only can be controlled by CH-1 Volume Pot on front panel.
2 input signals & 4 outputs:
Input 1 connect to CH-1 input socket, press the MIX1-2 switch, then this signal will be delivered to both CH-1/CH-2
for output and it volume only cab be controlled by CH-1 volume pot.
Input 2 connect to CH-3 input socket, press the MIX3-4 switch, then this signal will be delivered to both CH-3/CH-4
for output and it volume only cab be controlled by CH-3 volume pot.
Other operations are similar.
