EQ (E zone)
For tonal control of the aux, matrix and master output signals, the output channel EQ
has the option of a six-band sweep parametric EQ (PEQ) or an assignable graphic EQ
(GEQ).
PEQ
The parametric EQ section (E zone) of the channel strip (mix and master bays) allows
tonal control of the input signal. The E zone contains all of the PEQ controls, along with
a shelving mode selection button and another set of band selection buttons.
All of the outputs have six-band PEQs. Two of the six bands have three shelving modes
each, while another has just one. Any combination of the six bands can be used to
control the signal, although only one band can be adjusted in the E zone at any time.
However, the EQ processing area (GUI channel strip) displays four bands at any time,
and also has navigational controls.
3 threshold control knob, sets the signal level above which gain reduction
starts to be applied. Range is from -50dBu to +25dBu.
4 comp/gate up and down select buttons, for swapping dynamic section
control from compressor to gate, and vice versa.
5 Compressor make up gain control knob, compensates for the reduced
loudness of a compressed signal. Range is from 0dB to 24dB.
6 Compressor KNEE switch, controls how compressor starts to apply
attenuation as the signal goes through the threshold (see “About the
compressor graph” on page 252). For more information, see “Knee” on
page 290.
7 Compressor ratio/range/[ratio] control knob, adjusts amount of
compression applied to signals above threshold. Range is from infinity (∞)
to 1:1. When set to infinity it sets the compressor to limiter mode.
8 Compressor attack control knob, adjusts time for compressor to respond
after an
over-threshold signal. Range is from 0.2ms to 20ms (milliseconds).
9 MODE switch, selects compressor mode from the five compressor types
available (see “PRO2 compressor modes (dynamic)” on page 289).
10 Compressor release control knob, adjusts time for compressor to recover
after programme material falls back below threshold. Range is from 0.05s
to 3.00s (seconds).
11 Compressor ‘gain reduction’ meter (not displayed).
