EQ (E zone)
The input channel equaliser (EQ) is a four-band sweep parametric EQ (PEQ)
that allows tonal control of the input signal via the parametric EQ section, or E
zone, in the input channel strip. The four bands are treble, hi-mid, lo-mid and
bass, with an additional three shelving modes available for treble and bass.
Any combination of the four bands can be used to control the signal, although
only one band can be adjusted in the E zone at any time.
Each input fast strip contains the EQ on/o switch and quick access buttons for
channel and band selection.
The E zone contains all of the PEQ controls, along with a shelving mode selection
button and another set of band selection buttons.
