PROCESSING
Sidechain EQ
Dynamics units take copies of their input signals, analyse them, and work out how best to process the originals.
These copies are called sidechains. Sidechain EQ controls are used to process frequency components of the sidechain
signal in order to control which components of the input signal the dynamics unit will respond to.
With the Exp/Gate/Duck or Comp/Lim 1 processing tab selected, tap SIDECHAIN EQ within the control screen
to see the sidechain EQ controls. The SC LISTEN toggle button towards the bottom right of this screen allows the
user to listen to the sidechain signal whilst altering the EQ parameters. The sidechain
BYPASS
button in the screen
header allows the user to switch the sidechain EQ controls in and out, allowing the user to hear the difference the
EQ processing makes. The rest of the controls are explained in more detail here: See
”EQUALISER” on page 102.
Sidechain EQ is available to either the Exp/Gate/Duck or Comp/Lim 1 of each path - but cannot be used on both
modules at the same time.

Compressor2, as shown in Figures 11 & 12 does not have assignable sidechain EQ like exp/gate/duck and comp/lim1.
Instead, when in multi-band mode, the frequency range of each band can be adjusted. Multi-band compressors offer an
advantage over sidechain EQ for applications such as de-essing as they can apply gain reduction to a specific frequency
range, whereas using a regular compressor, the sidechain EQ can be set so that gain reduction is only triggered by certain
frequencies, but will apply the same amount of gain reduction across the whole frequency range.
