R
Low Freq (Low Frequency)
Selects the frequency of the low range (200 Hz/400 Hz).
Low Gain
Adjusts the gain of the low frequency.
Hi Freq (High Frequency)
Selects the frequency of the high range (4kHz/8kHz).
Hi Gain
Adjusts the gain of the high frequency.
M1 Freq (Mid 1 Frequency)
Adjusts the frequency of Mid 1 (mid range1).
M1 Q (Mid 1 Q)
This parameter adjusts the width of the area around the M1
Freq parameter that will be affected by the Gain setting.
Higher values of Q will result in a narrower area being
affected.
M1 Gain (Mid 1 Gain)
Adjusts the gain for the area specified by the M1 Freq
parameter and M1 Q parameter settings.
M2 Freq (Mid 2 Frequency)
Adjusts the frequency of Mid 2 (midrange2).
M2 Q (Mid 2 Q)
This parameter adjusts the width of the area around the M2
Freq parameter that will be affected by the Gain setting.
Higher values of Q will result in a narrower area being
affected.
M2 Gain (Mid 2 Gain)
Adjusts the gain for the area specified by the M2 Freq
parameter and M2 Q parameter settings.
+Level (Output Level)
Adjusts the output level.

02: Spectrum

Spectrum is a type of filter which modifies the timbre by
boosting or cutting the level at specific frequencies. It is
similar to an equalizer, but has 8 frequency points fixed at
locations most suitable for adding character to the sound.
