5.2 ADJUST EQUALIZERS (EQUALIZERS functions)
The
Chorum
organs are equipped with three graphic equalizers, one for the sound of the internal
speakers, and the other two for the audio output pairs [OUT 1] and [OUT 2] on the rear panel, and a low-
pass equalizer dedicated to the [GEN. SUB] output. The sound generated by the instrument can be
calibrated through the equalizers, in order to adapt to the environment and to the player's needs and
personal taste. To access the calibration page, select the
EQUALIZERS
field under the SETTINGS
menu. The following video page will appear:
the page contains the following fields:
o
INTERNAL:
graphic equalizer for the internal amplifier
(and therefore for the internal speakers).
o
OUT 1:
graphic equalizer for the [OUT 1] output pair, on the rear panel.
o
OUT 2:
graphic equalizer for the [OUT 2] output pair, on the rear panel.
o
SUB CROSSOVER:
low-pass filter equalizer for the
[GEN. SUB] output.
This is the graphic equalizers calibration page:
In the lower part of the screen there are the seven central band frequencies. To move the cursor from one
band to the other, use the buttons [FIELD
S
] e [FIELD
T
].
Each band can be modified, using the buttons [VALUE +] and [VALUE -] from +9 dB (maximum signal
gain) to -9 dB (maximum signal dampening). The level of gain or attenuation is graphically represented
and can be compared to the grading scale on the left side of the screen.
The following graph shows how the graphic equalizers works.
