Chapter 4: Effect parameters
3-Band Parametric Equalizer — EQ
The EQ effect section features a 3-band equalizer, each band having boost/cut control and vari­
able frequency selection. The Mid EQ provides up to 30 dB of cut and can be used as a notch
filter.
LoF Low Frequency 20 Hz ~ 2.8 kHz
L og Low Gain - 1 5 d B ~ + 1 5 d B
MiF Mid Frequency 80 Hz - 8.0 kHz
MiG Mid Gain -30 d B ~ + 1 5 d B
HiF High Frequency 500 Hz ~ 16 kHz
HiG High Gain - 1 5 d B - + 1 5 d B
LVL Output Levei - oo, -30 dB ~ +6 dB
Modulation — MOD
The modulation effect section can produce 11 different types of modulation effect.
Stereo Chorus — CHO
The chorus effect splits the signal into two, modulates one signal, then mixes the two signals
together. It produces a rich thickening type effect — like a chorus of guitars playing together.

DLY Modulation Delay 0.1 ~ 100.0 msec
The delay time before the signal is
modulated.
* A short delay time (1.9 msec or less) will
affect the depth of pitch modulation.

0=mono.
10=wide stereo.
MIX Mixing Balance 0 - 1 0 0 %
0 = dry signal.
50 = 50% chorus effect 50% dry signal.
100 = 100% chorus effect.
LVL Output Level - =>o, -30 dB - +6 dB Sets the output level of the effect.
