Scheps Omni Channel / User Guide
This does the trick, but you’re compressing the ba
ss in places where you don’t need to. Only at low
frequencies is there a conflict between the bass and the voice, so you want to trigger compression only
when the vocalist sings low notes. Add a sideband EQ boost around 200 Hz to 400 Hz, which is where
bass and voice are most likely to collide. This biases the sidechain to activate the compressor mostly at
low-frequency vocal sounds.
Set the Threshold so that only this accentuated low-frequency boost triggers gain reduction.
Turn the external sidechain on or off wit
h the EXT SC button.
Shaping the Sid
echain
The compressor and gate sidechain EQ controls that are located in the SC section of the Expanded view. Use these
filters to shape the frequency content of the sidechain that’s going to the attenuation device. This applies to both
internal and external sidechains. This equalization assigns different compression priorities for different frequencies.
By default, all sidechain controls are inactive: SC on/off; EXT SC;
and all SC EQ
controls. Touch any EQ control in the sidechain
panel and the sidechain EQ section will become active. The SC
Filters button—at the top of the Expanded view, or at the bottom
of the Collapsed view—will light, indicating activity in the
sidechain.
Click the SC Filters button to turn all sidechain filters on or off. This
lets you audition the sidechain to hear how sidechain EQ is
influencing sidechain performance.
