not affect the compressors' gain reductions and can be used as a graphic equalizer
to fine-tune the spectral balance of the program material over a ±6 dB range.
There are two sets of mixer controls, one for the analog processing chain and one
for the HD processing chain. The mixer controls for the HD processing chain also de-
termine the spectral balance of the low-delay monitor output.
The range of the band mix controls has been purposely limited because
the only gain control element after these controls is the back-end clip-
ping system (including the multiband clipper / distortion controller),
which can produce considerable audible distortion if overdriven. The
thresholds of the individual compressors have been carefully tuned to
prevent audible distortion with almost any program material. Large
changes in the frequency balance of the compressor outputs will change
this tuning, leaving the 8500S more vulnerable to unexpected audible
distortion with certain program material. Therefore, you should make
large changes in EQ with the bass and parametric equalizers and the HF
enhancer, because these are located before the compressors. The com-
pressors will therefore protect the system from unusual overloads caused
the chosen equalization. Use the multiband mix controls only for fine-
tuning.
You can also get a similar effect by adjusting the compression threshold
of the individual bands. This is comparably risky with reference to clipper
