Parameter Descriptions
MPX 550
5-9
R Dly 1, 2, 3 (0ms to 5.060sec)
Sets the delay time of right voice 1, 2, or 3. The Dly/Eko
effect has three independent voices on each side.
Rate (0 to 50.05Hz)
Controls modulation speeds.
Res 1, 2 (-100 to +100%)
In Chorus programs, control the amount of feedback
signal.
Resonanc (-100 to +100%)
In Flange programs, controls the amount of feedback.
Rt HC (28Hz to 19.4kHz, off)
Sets the frequency above which high frequencies are
rolled off in the reverberated signal, causing reverberated
signals to grow progressively darker. This results in a
more natural sound because it simulates the effect of air
absorption in a real hall. Setting this parameter to a
low- frequency dampens the audio as it re-circulates, and
consequently can actually shorten the reverb time.
RvbLvl (off, -48dB to 0dB)
In Ambience programs, controls the amount of "extra"
longer-decay reverb added to the effect. In Ambience,
short-decay early reflections create a real-room sound.
Shape (0 to 255)
Controls the buildup of the early reflections that most
audibly create the sound of a real room. Shape and
Spread work together; if either is set to 0, the other has
no effect.
Size (4.0 to 76.0m)
Sets the rate of echo density buildup after the initial
period (which is controlled by Diffusion). It also acts as a
master control for Decay. Size changes a reverb sound
from very small to very large. It is recommended to set
the Size control to the approximate size of the acoustic
space that is being created before adjusting other
parameters. The size in meters is roughly equal to the
longest dimension of the space. (Adjusting the Size
parameter causes the program to re-load.)
