THE MCLASS EFFECTS677
6. Route one pair of the split outputs of the Spider to the MClass Equalizer inputs.
7. Route the Equalizer outputs to the Sidechain inputs on the MClass Compressor.
8. Route another pair of the split outputs of the Spider to the MClass Compressor.
Now, the compressors normal audio inputs are fed the unprocessed signal, and the sidechain inputs are fed the
equalized signal.
9. Next, route the outputs of the Compressor to inputs on a mixer device.
10.Activate the Solo Sidechain button on the compressor’s front panel.
You will now only hear the equalized signal.
11.Now use the parameters on the MClass Equalizer to boost the frequencies you wish should trigger the gain re-
duction and cut the frequencies you wish to avoid triggering the gain reduction.
You can use rather extreme eq settings - the signal will not be heard when Solo Sidechain is deactivated anyway.
E.g. for de-essing you should separate and boost the offending “S” frequencies as much as possible.
12.Deactivate Solo Sidechain when you have finished tweaking the equalizer.
Now, the compressor will be more sensitive to the frequency area you tuned in with the equalizer, and thus react
more to these frequencies. Note, however, that the whole signal will still be compressed - not just the boosted fre-
quencies - so in case of de-essing you should usually use fast Attack and Release settings so that the gain reduc-
tion does not affect the rest of the program too much.
CV Outs
On the back of the MClass Compressor you can find a “Gain Reduction” CV out connector. This can be used to mod-
ulate other parameters with the amount of gain reduction applied by the compressor. This means that the compres-
sor works as an envelope follower. You could for example have the audio signal level control pan in a mixer or a synth
parameter.
