3: DESCRIPTIONS OF THE EFFECT PROGRAMS
& THEIR PARAMETERS
/ THE BALANCE AND OUTPUT

Since all of the REX 50 effects have the same BALANCE
and OUT LVL (Output Level) parameters, we'll describe
them here and leave them out of the descriptions of
each effect that follow. BALANCE and OUT LVL are
normally the last two parameters called in an effect's
parameter list.
Effect/Direct Signal Balance (BALANCE): 0 — 100%
This parameter adjusts the balance between the
direct sound and effect signals. At 100% only the
effect sound is delivered from the REX50 outputs,
while at 0% only the direct sound is output. At a set­
ting of 50%, the direct and effect sounds are out­
put in approximately equal proportions.
Effect Output Level (OUT LVL): 0 — 100%
This parameter sets the output level of the effect.
This is particularly handy for matching the levels bet­
ween effects when setting up an effect sequence
for a live performance.

Reverberation is the warm musical "ambience" you ex­
perience when listening to music in a hall or other
properly-designed
acoustic environment. The REX50
offers four different reverb effects, simulating types of
reverberation you would experience in a large hall (REV
1 HALL), in a smaller room (REV 2 ROOM), a reverb
effect ideally suited to vocals (REV 3 VOCAL), and the
type of reverberation produced artificially by a plate
reverberator (REV 4 PLATE).
Reverb Time (REV TIME): 0.3 - 99.0 s
The length of time it takes for the level of reverbera­
tion at 1 kHz to decrease by 60 dB — virtually to
silence. In a live setting, this depends on several fac­
tors: room size, room shape, type of reflective sur­
faces, and others.
High Frequency Reverb Time Ratio (HIGH): 0.1 —
1.0
Natural reverberation varies according to the fre­
quency of the sound. The higher the frequency, the
more sound tends to be absorbed by walls, fur­
nishings and even air. This parameter allows altera­
tion of the high-frequency reverb time in relation to
the overall reverb time.
Initial Delay (DELAY): 0.1 - 50.0 ms
This parameter represents the delay between the
direct sound of an instrument and the first of the
many reflections that together form reverberation.
High-pass Filter (HPF): THRU, 32 Hz - 1.0 kHz
Permits rolling off the low-frequency content of the
reverb signal below the set frequency. The HPF is
OFF when set to THRU.
Low-pass Filter (LPF): 1 kHz - 11 kHz, THRU
Permits rolling off the high-frequency content of the
reverb signal above the set frequency. The LPF is
OFF when set to THRU.
