EQ AND FILTERS
EQ is available on all paths without
restriction. Each path has access
to six full range, fully parametric,
switchable response EQ bands.
Each EQ band has a frequency range
from 20Hz to 20kHz and can have either
a high-pass filter, low shelf, notch, bell,
high shelf or low-pass filter response.
See Fig 1.
Given the flexible and configurable
nature of the surface, the EQ control
layouts used here are available on both
the PROCESSING-OVERVIEW mode
which was briefly described in the
CONTROL PANEL MODES section and
the PROCESSING-EQUALISER mode
as shown and described here in greater
detail. These controls would only affect
the currently assigned path.
On/Off
Buttons in the left button cell switch all
bands 1-4 on or off together and bands 5
and 6 on or off together.
A & B alternate EQ Settings
Two EQ curves can be created per
channel using the EQ Settings A & B
buttons on the TFT screen. Tapping these
flips between the two EQ curves for quick
EQ changes or comparisons. The Copy
EQ Settings buttons on the TFT screen
copies EQ A > EQ B or EQ B > EQ A.
Reset EQ A and Reset EQ B
Holding the Reset EQ A or Reset EQ B
buttons for a second will reset the gain,
frequency and response (and Q where
applicable) for all EQ bands.
Gain
The left column of Control cells contains
gain controls (where relevant) for all six
bands.
