Even if you do not like to read manual, please read this section.   
 
This procedure is very important, even if you do not like to read manual. Please read 
this section. After you connected up the system, you are ready to set the initial set up 
for every input channel, the matching of every input trim to the signal source is crucial. 
Every  detail  will  affect  the  final  output  of  the  mixer.  Basically,  the  input  sensitivity 
adjustment, channel fader, groups and output fader is the main factors. You should try 
to set only as much microphone trim as required to achieve good balanced between 
signals. It the input gain is set too low, you will not get enough gain on the faders to 
push the signal up to adequate level, if the input gain is set too high, the channel fader 
will need to be pulled down in compensation, but leave the greater risk of feedback 
because a small fader movements will have a very significant effect on output level. 
Certainly,  the  limited  fader  travel  path  will  not  successful  in  the  mixing  procedure. 
Please use the following set up procedure, do not use the old way: turning the output 
up until they clip and then backing off 
 
    Follow the procedure for each channel in use 

 

Set all faders and gain controls all the way off. 

 

Phantom powered microphone should be connected before the+48V is switched on. 

 

Set power amplifier level to 70

 

Set the CTRL RM level and Headphone level to about 50%. 

 

If you want to hear what you are doing later, plug your headphone into the phone 

output socket

or hook up your control room amplifier system to the Control Room 

outputs.

 

 

Set EQ control at center position. 

 

Set PAN and BALANCED knobs at center position.

 

 

You need a headphone to continue.

 

 

Apply a typical performance level signal monitoring the level on the LED meter. 

 

Adjust the input gain until the meter show in the amber section with occasional peak 

to  the  first  red  LED  at  maximum  source  level.  This  allows  enough  headroom  to 
accommodate peak and the maximum level for normal operation; you can listen to 
them through your headphone. 

 

For +4 line level audio signals, slide the+41-10 switch to +4. 

 

For -10 sources. slide the +4/-10 swatch to -10. 

 

For microphone source, the gain control adjustment will depend on what kind of the 

microphone you use

normally turn the gain clockwise around 2-3 o’clock. But please 

ask the singer to perform alive, do not whisper. If they did not wake up while you are 
doing the sound check when they are back to alive, you might drive the mixer overload 
or produce the feedback, because you Set the gain too high during the initial set up. 

 
Most often mistakes in audio installation are incorrect and deflective audio 

 

Repeat this procedure on every other channel, when more channels are added to the 

mixer. the meters LED may move up to the red section

adjust the overall level using 

the Pilaster faders if necessary.
