5. Press CURSOR [DOWN] to access up the parameters in the bottom section
of the display:
Level of the direct sound: Turn [V1] (DIRECT) from 0 to 127 to set the amount
DELAY TIME:
* DELAY TIME defines the length of the delay and the time interval of repeats.
* "Sample" is the smallest unit of time on this system. One sample represent a time
duration of about 0.021 ms at 48 kHz, or about 0.023 ms at 44.1 kHz.
The current setting is displayed as a DISTANCE in meters from the sound source.
The setting is also displayed in TIME as milliseconds based on the current sample
rate.
In DISTANCE on the screen, the setting is displayed as converted into a distance
from the sound source (in meters). In TIME, the setting is displayed as converted into
time (in ms = 1/1000 second) based on the current sample rate.
Level of delay sound:
Feedback level:
* Feedback level determines how many times the delay sound is to be repeated.
6. Press CURSOR [UP] to access the parameters in the top section of the
display.
• To set the amount of attenuation below the selected LO DAMP FREQ, turn [V1]
(LO DAMP GAIN) from -30.0 to +6 dB.
• To select the frequency below which attenuation will occur, turn [V2] (LO
DAMP FREQ). You can select any frequency from 20 Hz to 2 kHz.
• To set the amount of attenuation above the selected HI DAMP FREQ, turn [V3]
(HI DAMP GAIN) from -30.0 to +6 dB.
• To select the frequency above which attenuation will occur, turn [V4] (HI DAMP
FREQ). You can select any frequency from 200 Hz to 20 kHz.

of the original, un-delayed signal to be heard.
Turn [V4] (TIME) to select an amount of delay from
0 to 14,400 samples.
Turn [V2] (DLYLEVEL) from 0 to 127 to set the level
of the delayed signal.
Turn [V2] (F-B LEVEL) from 0 to 127.
The DELAY TIME
parameter works in
conjunction with the
PHASE DELAY parameter,
which also allows you to
delay a channel's signal by
small increments to correct
phasing problems (p. 69).
Together, their delay times
cannot exceed 14,400
samples in total.
The high (low) frequency
damping function allows
you to attenuate the level of
delayed sounds above or
below a specified
frequency. This can help
produce a natural-
sounding echo effect (p.
238).
With the proper settings,
the feedback delay function
can also be used as a comb
filter (p. 233).
