before attempting to connect your PBM4 to the main

AC.

5. INSTALLATION AND CONNECTION

Ok, you have got to this point and you are now in the position to successfully operate your PBM4. However, we advise

you to read carefully the following section to be the real master of your own monitor. 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.

Turn down all input and output controls.

Connect phantom powered microphones before switching on the +15Volt phantom power switch.

Set the output level of your PBM4 at no more than 75%.

Now, set the MONITOR level at no more than 50%. In this way you will be able to hear later what you

doing by connecting a pair of powered monitor speakers.

Position EQ controls on middle position.

Now repeat the same sequence for all input channels. The main LED meter could move up into the

section. In this case you can adjust the overall output level through the MAIN MIX LEVEL control.
