FIXED PROCESSORS_____________________________________
These processors make up the three different stages of the System Processor’s Gain Structure (see page 16
for more on this topic). They are referred to as fixed processors because the gain and mix blocks in the signal
flow diagram cannot be moved or deleted.
Input Gain
The Input Gain processor contains individual controls for all four input channels. Double-click on the gain block
at the left end of any input channel strip to open this window, as pictured below in figure 27.
Scaling Options
Use these buttons to scale each input channel to match the output level of the equipment in line before
the System Processor. Click to toggle between -10dBV or +4dBu levels. The default setting is +4dBu.
+4dBu selected
-10dBV selected
Signal Polarity
Click this button to invert the polarity of the signal entering the input channel strip. The default setting is
normal polarity.
