PARAMETERS ACCESSED BY THE PARAM KEY
Distortion (DISTORTION): 0 – 100%
This parameter sets the "degree" of distortion produced. A
setting of 0 produces a perfectly clean sound, while a setting
of 100 produces the most heavily distorted sound.
Midrange EQ Frequency (MID FRQ): 250 Hz – 5.6
kHz
Sets the mid-frequency range to be boosted or cut using the
next parameter: MID GAIN.
Midrange EQ Gain (MID GAIN): -12 – +12 dB
Boosts or cuts response in the frequency range set by the MID
FRQ parameter (above). A setting of 0 produces no boost or
cut. Minus settings (e.g: -6 dB) cut response in the selected
frequency range, while plus settings (e.g: +12 dB) boost
response.
Treble Boost/Cut (TREBLE): -12 – + 12 dB
Permits boosting or cutting the high-frequency range. Minus
settings (e.g: -6 dB) reduce the high-frequency content of the
sound, while plus settings (e.g: +6 dB) emphasize the high-
frequencies.
Distortion Delay (DELAY): 0.1 – 1480.0 milliseconds
Sets the delay between the direct sound and the beginning of
the distortion effect.
PARAMETERS ACCESSED BY THE INT PARAM
KEY
Trigger Level (TRG. LEVEL) : 0 – 100
The level of the input signal which allows the gate to open (or
applies a trigger, in other words) can be set. The larger the
value, the larger the input signal needed to open the gate. If
this is not specified, the gate will not open.
Release Time (RELEASE) : 3 ms – 24000 ms
Tis is the time between the point where the gate begins to
close and the point where it is fully closed. The larger the
value, the smoother the cut-off of the reverberation sound
becomes.

EXCITER PROGRAM

n 37. EXCITER

This program artificially adds appropriate harmonics to the
input signal, adding luster-and effectively bringing "buried'
sounds to the foreground.
HPF FRQ: 500 Hz – 16 kHz
Determines the range of high harmonics added to the input
sound. The smaller the value, the greater the range of high
harmonics applied.
ENHANCE: 0 – 100%
Sets the level of the harmonics added to the input sound. The
higher the value, the greater the exciter effect.
Exciter/Direct Sound Mix (MIX LVL): 0 – 100%
Sets the mixture or balance between the direct input sound and
the applied harmonics.
DELAY: 0.1 – 740.0 ms

The SPX900 multi-effect programs combine compressor,
distortion, equalizer or dynamic filter (access via EQ key),
reverb and chorus or exciter effects. Refer to the effect
configuration diagram for each program to understand how the
various effects are "connected."
In all cases the first parameter display allows turning each
effect ON or OFF. Use the PARAM and SCROLL BACK keys
to move the underline cursor to the desired effect, then use the
parameter or key to turn the effect ON of OFF:
= OFF. = ON. In this example display
COMPRESSOR (CO). CHORUS (CH) and REVERB (RV) are
ON. while DISTORTION (DI) is OFF.
Once the desired effects have been selected, use the PARAM
key to move on to the main parameters. Only parameters for
effects that are turned ON will appear.
PARAMETERS ACCESSED BY THE INT PARAM
KEY
All of the multi-effect programs have both COMPRESSOR
and DISTORTION: however, all parameters for these are
accessed through the INT PARAM key.
Compressor Attack (CO. ATTACK): Refer to COMPRESSOR
on page 22.
Compressor Release (CO. RELS): 10 – 1000 ms. Refer to
COMPRESSOR on page 22.
