EQUALIZ ( Equalizer)
In this mode, you adjust the settings for the Equalizer.
An Equalizer is used to adjust the tonal quality. Th
e XK-1C’s built-in Equalizer con-
sists of 3 bands and a recreation of the unique “tone” control that was part of the
vintage B-3. Th
e Bass and Treble bands are handled by “shelf ” equalizers, and the Mid
band is handled by parametric control.
To locate this mode:
PATCH EQUALIZER
❶
TONE CONTROL (P)
Th is is a simulated original B-3 TONE CONTROL. Its response is unique, but its
basic response is to gently cut the overall treble above 200Hz.
Th
e setting range is -9 to +9, and it becomes neutral when set at “0”. “-1” corre-
sponds to the maximum of the original B-3 tone control, “-5”, the middle, “-9”, the
minimum. Th
e tone control found on the original B-3, was only available at “minus”
settings, but here you are able to “plus” the settings as well.
PATCH EQUALIZER and MASTER EQUALIZER

❸, ❾ GAIN - MIDDLE (P), (G)
❹, ❿
GAIN - TREBLE (P), (G)
Adjusts the Boost/Cut of Bass, Mid-range and Treble respectively.
Th
e setting range is -9 to +9. It is fl at at 0.
❺, ⓫ FREQUENCY - BASS (P), (G)
❻, ⓬
FREQUENCY - MIDDLE (P), (G)
❼, ⓭
FREQUENCY - TREBLE (P), (G)
Adjusts the center frequency (MIDDLE) / turnover frequency (BASS, TREBLE) to
be attenuated.
Th
e setting range is 20Hz - 200Hz for BASS, 250Hz - 3.1kHz for MIDDLE, 4.0kHz
- 8.0kHz for TREBLE.
The sound may distort if gains are raised too high. Adjust accordingly.
NOTE: The parameter with (P) indicated is a patch parameter, and is recorded to each patch.
(G) indicates “global parameter”, which is recorded upon being set, and is common
with each patch.

THE EFFECTIVE USE OF THE MID-
DLE FREQUENCY
The frequency response of the horn rotor in the
Leslie speaker is not fl at. It has a peak from 1kHz to
3kHz. This peak is eff ective in “cutting through” any
ensemble playing.
If you use this organ through line out without a Le-
slie speaker, you can duplicate eff ect by setting the
FREQUENCY- MIDDLE to approximately 2kHz, and
the GAIN - MIDDLE to “+”.
TURNOVER FREQUENCY
The MIDDLE of this equalizer controls a point of fre-
quency. This is called center frequency. The BASS
(or TREBLE) controls lower (or higher) than speci-
fi ed frequency. This is called turnover frequency.
PATCH PARAMETERS
The equalizer is designed to be a patch parameter
to be actively utilized as a part of sound making
parameter.
Use the Master Equalizer for tonal compensation
to match the performance stage.
See “Function mode” (P. 62) for operation details.
