Position panoramic (PAN) control on center position.
Increase the input gain properly for maintaining the good headroom and ideal dynamic range.
Depending on the actual application, turn slowly the input and output level controls for obtaining the maximum
gain before distortion.
Now repeat the same sequence for all input channels. The main LED meter could move up into the red section.
In this case you can adjust the overall output level through the MAIN MIX control.
6. INSTALLATION AND CONNECTION
Ok, you have got to this point and you are now in the position to successfully operate your PBM8.250/500. However,
we advise you to read carefully the following section to be the real master of your own mix. Not paying attention enough
to the input signal level, to the routing of the signal and the assignment of the signal will result in unwanted distortion,
a corrupted signal or no sound at all. So you should follow this procedure for every single channel:
Now, set the MONITOR level at no more than 50%. In this way you will be able to hear later what you are doing
connecting a pair of headphones or a pair of powered studio monitor speakers.
