Modulation
Phaser (PRESET bank)

By cyclically varying the frequencies whose phase is shifted, this effect creates a sense of space and movement. A phase shift circuit is

used to delay the phase of specific frequencies.

Each aspect of the sound is controlled by the following effect parameters.
Modulation signal: FREQ., DEPTH, PHASE
Phase shift: FB.GAIN, OFFSET, STAGE
Tempo synchronization: SYNC, NOTE, TEMPO
Filter/equalizer: LSH G, LSH F, HSH G, HSH F
Output level: OUT LVL, MIX BAL.

The following tables show the default parameter values for the effect belonging to the Phaser type (PRESET bank).

■Basic parameters
■Fine parameters
Parameter name Range Explanation
FREQ. 0.05—40.00 Hz Speed of modulation. Increasing this value will make the modulation repeat at a shorter interval.
DEPTH 0—100% Modulation depth. Increasing this value will make the modulation deeper.
FB.GAIN –99%—+99% Amount of feedback for the modulated sound. Raising this value will increase the amount of feed-
back, emphasizing the modulation. Negative (–) settings will invert the phase of the feedback.
OFFSET 0—100
Offset value for the frequency whose phase is shifted. Raising this value will move the frequency
upward, and lowering it will move the frequency downward. The frequency being phase-shifted
will change around this value. FREQ. sets the speed of change, and DEPTH sets the amount of
change.
PHASE 0.00—354.38 dg Phase difference between the modulation signals of the L channel and R channel. This lets you con-
trol the spaciousness of the sound.
STAGE 2, 4, 6, 8, 10, 12, 14, 16
Number of stages in the phase shift circuitry. Raising this value will produce a more complex sense of modu-
lation.
Parameter name Range Explanation
MIX BAL. 0—100% Balance between the original sound and effect sound. At a setting of 0% only the original sound
will be output; at a setting of 100% only the effect sound will be output.
OUT LVL 0—100% Output level after the original sound and effect sound have been mixed.
Decrease this value if you want to lower the output. At a setting of 0% there will be no output.
LSH G –12.0—+12.0 dB Gain of the low shelving filter. This adjusts the volume of the low-frequency region. Positive (+)
settings will boost the low-frequency region, and negative (–) settings will attenuate it.
LSH F 21.2 Hz—8.00 kHz Frequency of the low shelving filter. The LSH G gain applies to the frequency region below this set-
ting.
HSH G –12.0—+12.0 dB Gain of the high shelving filter. This adjusts the volume of the high-frequency region. Positive (+)
settings will boost the high-frequency region, and negative (–) settings will attenuate it.
HSH F 50.0 Hz—16.0 kHz Frequency of the high shelving filter. The HSH G gain applies to the frequency region above this
setting.
SYNC ON, OFF
Switches tempo synchronization on/off. If this is ON, the speed of modulation will synchronize to
the tempo synchronization source specified by “TEMPO SOURCE” (page 23). The NOTE value
will be set to the synchronized tempo value.
NOTE *a
*a.
This parameter is used for tempo synchronization. If SYNC is ON, the FREQ. value will be set
according to this value and the TEMPO value. This value is ignored if SYNC is OFF.
TEMPO 25—300 This parameter is used for tempo synchronization. If SYNC is ON, the FREQ. value will be set
according to this value and NOTE. This value is ignored if SYNC is OFF.
