5.1 Power on and power off

Input AC220V 10%, switch is turn on, blue power indicator light up , then the power is turned on. After 
3 to 5 seconds, the amplifier is working normally. When switch is turn off, blue power indicator go out , 
then the power is turned off, all the indicators go out at the same time.

5.2 Mute function

MIC1 input audio signal (2~350mV):
Press "PRIORITY" button on the front panel , "PRIORITY MIC" indicator light up, "MUTE" potentiometer 
set maximum, MIC1 potentiometer set to  scale "4" or higher, priority  function is working. MIC1 output 
normally, the  other  channel  signal is muting , mute  result is  controlled by audio signal input on MIC1, 
MIC1 volume potentiometer and "MUTE potentiometer". Press "PRIORITY" button; MIC priority function
is turned OFF, MIC1 output mixed with other channel.

Note

: When on EMC priority, MIC1 signal is muted.

5.3 Function of music signal automatic input selection and audio/video input selection

5.3.1

 

The real panel input selector switch "AUTOSEL" in the 0N position, "INPUT SELECTOR AUTO" 

indicator  lights, this moment is the automatic audio input selection state, between "BGM, VCD, DVD" 
channel, switching time is about 3 to 5 seconds, choose the audio input channels, and the front panel 
of the corresponding channel indicator will be synchronized lighted(eg DVD), while the video signal 
input in "VIDEO INPUT DVD" port will also be output in  "VIDEO OUT" port synchronously, and next 
to the main amplifier output. When there is no input audio source, the default BGM channel.

 

5.3.2 The rear panel input selector switch "AUTOSEL" in the OFF position, "INPUT SELECTOR MANUAL
indicator lights, then manually select the input audio source; press any button of "BGM, VCD, DVD" 
below the panel audio input selection " AU-DIOSELECTOR ", indicator lights, means select the input 
channel which indicator shows. under the current state, the output signal source from pre-amp and 
power amp is the channel output signal which indicator shows; and the current video output port is also 
synchronized to match the output (for example: when the DVD audio and video signal input channel, 
press "DVD" button representative DVD channel, then lights up "VIDEL INPUT DVD" lights, and turn 
DVD audio signal path to the pre-amp output port, while the video signal input in "VIDEO INPUT DVD" 
port will Synchronous output in "VIDEO OUT" port, and power amp output. )
Note: When the machine is in automatic audio input selection status, manual operation is disabled.

5.4 MUSIC signal channel switching function

 press LRSEL key on the panel, L+R indicator lights, input L, R stereo signal, the power amplifier 

output stereo signal, input MONO signal, the power amplifier output MONO signal;

 press LRSEL key on the panel, L+L indicator lights, input mono L signal, the power amplifier output 

is two L signal;

 press LRSEL key on the panel, R+R indicator lights, input mono R signal, the power amplifier output 

is two R signal.
Note: This function setting is only available for the music (DVD, VCD, BGM) input channel, MIC1~3
input channel settings are invalid.
