EQ
The four-band EQ provided on the first 48 channel
modules of the DM-4800 allows precise sound shap-
ing, combined with flexibility, and repeatability,
thanks to the library store and recall facilities.
It is also easy to copy and paste EQ settings from one
module to another (see “Fat channel” on page 27.
To view the EQ settings for a module, press the
MODULE
key until the EQ page is shown.
TIP
The instructions here refer to POD use, but you can put
the encoders into EQ mode, and use the encoders to
adjust individual EQ parameters for the selected chan-
nel (see “Encoders” on page 22 for full details). It is also
possible to link the screen display to the encoders, or
the other way round, so that changing one automati-
cally changes the other. See “PREFERENCES” on
page 43.
You can also use the dedicated “fat channel” keys and
controls as described in ““Fat channel”” on page 27.
Use the cursor keys to move the “box” around the
screen, and the four POD encoders to change the val-
ues of the gain (where appropriate), frequency, Q
(where appropriate) and the type of filter for the
selected band.
Turn the EQ on and off using the
EQ
key in the “fat
channel”, or by using the on-screen
EQ
button (cir-
cled in Figure 5.9,
Module EQ screen
)
Turn the individual band highlighted by the on-
screen box on and off using the
ENTER
key.
As you make changes to the EQ setting, the graph at
the top of the screen changes as does the one by at
the top of the “global section”.
All bands have the same frequency range: from 31Hz
to 19kHz (in 112 steps).
The amount of gain is ±18dB for all bands.
Q (where appropriate) can be set to any of the fol-
lowing 24 values: 8.65, 4.32, 2.87, 2.14, 1.71, 1.41,
1.20, 1.04, 0.92, 0.82, 0.74, 0.67, 0.61, 0.56, 0.51,
0.47, 0.44, 0.40, 0.38, 0.35, 0.33, 0.30, 0.28, or 0.27.
The types of EQ filter available are:
Low band:
Low shelf (
L.SHELF
), peak (
PEAK
), and
high-pass filter (
HPF
)
Low-mid band:
Peak (PEAK) or notch (
NOTCH
)
High-mid band:
Peak (PEAK) or notch (
NOTCH
)
High band:
High shelf (
H.SHELF
), peak (
PEAK
), low-
pass filter (
LPF
)
Note that the following parameters are used by the
different EQ filters:
Peak filter:
Gain, Frequency, Q
Shelving filters (high and low):
Gain and Frequency
HPF and LPF:
Frequency
Notch filters:
Frequency and Q
Unused parameters are grayed out on screen or if
encoders are elected to set the EQ, the encoders for
the unused parameters are disabled, and no indicators
are lit. The “fat channel” controls have no effect on
unused parameters.
Encoders and EQ
The encoders can be used to
make EQ settings (unmodified
ENCODER
key 4) as
described in “Encoders” on page 22.
