5. WIRING UP

OK, you have got to this point and you are now in the position to successfully operate your SX
series. However, we advise you to read the following section carefully to be the real master of
your own mix.
Not paying enough attention to the input signal level, the routing of the signal and the assign-
ment 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:
1. Turn down all Input and output gain controls.
2. Connect phantom powered microphones before switching on the +48 Volt phantom power
switch.
3. Set the output level of your SX series mixer or the connected power amplifier at no more than
75%.
4. Now, set the CONTROL ROOM/PHONES 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.
5. Position EQ controls on middle position.
6. Position panoramic (PAN/BAL) control on center position.
7. With a pair of headphone or studio monitor speakers are connected, apply a Line Level input
signal so that the PEAK LED does not light up.
8. Increase the input gain properly for maintaining the good headroom and ideal dynamic
range.
9. Depending on the actual application, turn slowly the input and output level controls for
obtaining the maximum gain before distortion.
10. 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.
