[4] S/C HI EQ
This switch allows you to boost (B) or cut (C)
the treble feeding into the Essence side chain (or
control circuitry). In the centre position, the control is
bypassed. If you apply boost into the S/C, then the
compressor will be more sensitive to the treble
frequencies, and more compression is applied. If you
apply cut, the compressor becomes less sensitive at
high frequencies.
[5] S/C LO EQ
Similar to the S/C EQ HI, this switch applies
boost (B) or cut (C) in the bass register or low
frequencies.
[6] LINK
This switch connects the Essence S/C to other
Essence compressors that may be installed in the rack
and will provide tracking of the two linked units for stereo
or multi channel compression tasks.
!! IMPORTANT NOTE !!
The Essence should NOT be linked with any other type or
brand of compressor – damage may result! Please
consult the rack manufacturer’s instructions for setting
up the link function in your rack.
[7] S/C INS
Side Chain Insert. This switch connects
whatever is feeding the S/C return into the compressor
control circuitry (slot 2 female XLR connector). The Side
Chain Insert allows you to connect another device (such
as an equaliser) to modify the Essence compression
