STEREO DIGITAL EFFECTS PROCESSOR
The new digital effects processor lets you create an endless variety
of diverse effects starting from 16 basic patches (signalled 0 to F on
the one-figure display) that you can freely alter by the 'parameter'
control.
At startup, program 9 (VOICE REVERB) is auto-loaded.
To select the programs, you simply use the ▲ and ▼ pushbuttons
to scroll through programs up and down, respectively.
EFFECTS SETUP
1 – Switch the effect to operation by pushing its
ON button. A red LED lights up to signal its status.
2 – Bring the effect fader and the L/R master faders
near to the '0' position on their scale (at working
level).
3 – Set the channel volume and the effect send level,
with EFF control, on the input channels you wish to
add effects to.
4 – Carefully inspect the red LED CL:
• the red LED should blink occasionally
• if the red LED is constantly lit, you could suffer
severe distortion on the effect signal. This isn’t due
to the processor itself, rather it is common on digital
processors of any price because of the digital
technology itself. In case, reduce the level of the
EFF controls on the input channels until the red LED
light up only on loudest peaks.
5 – You can alter the effect timbre with the TONE
control on the effects processor: turn it clockwise
to 'brighten' the effects, or counter-clockwise to
'darken' it.
6 – Route the effect to the main outputs with the
BAL control, and/or to the stage monitors with the
AUX control, then set its volume fader at the desired
levels.
7 – Select the program you wish to use with the
▼ and ▲ buttons.
Use the chart on the next column as a reference to
recognize the programs.
Feel free to experiment with any program until you get the sounds
that most satisfies your taste.
• Especially aimed to live music applications VOICE REV. (9), FAST ECHO + REV.
(A) and SLOW ECHO REV. (B) effects are based on a particular algorithm
developed to minimize feedback risks when working with stage monitors.
•• The effects EARLY REFLECTIONS (6) and ROOM REV. (7) are specially
suited to sampled signals (keyboards, electronic drums, samplers..).

Effects description
Is basically a very short slap-back delay, the
control PARAMETER increases the delay time.
Again, but with longer delay times, hence a more
'spacious' flavor to it. The PARAMETER control
has the same function.
A digital 'clone' of the effect built in the Montarbo
reverb units of the sixties, a vintage classic that
never went out of fashion. PARAMETER controls
the 'lenght' of the effect.
Again the preveious effect, but slightly more
'open'. Same function for the PARAMETER
control.
Basically an auto-panned delay, popular on many
rock hits, the samples are being routed alternative-
ly to full left and full right master. PARAMETER
controls the delay time, i.e. the lenght of the
sample.
Unmistakably a 'must' of many 80's records,
starts at low level, builds up and quit abruptly.
Usually served with percussion. PARAMETER
controls the reverb time, hence the duration of
the effect.
Generates the initial part of the reverb without
the decaying 'tail' of the effect. It makes for
thicker and more aggressive sound without
increasing its decay time. Usually it is used to
colour vocals or horns solos in contemporary
productions. PARAMETER controls the timespan
in between early reflections.
The typical short reverb, great with percussions.
The PARAMETER control sets the room size.
Simulates a much bigger space, as the name
implies. PARAMETER, of course, sets the room
size.
Specially tailored to support and enrich the lead
vocals. PARAMETER controls the ambient flavour
to it.
A fast, short slap-back delay combined to a reverb
in a vocal oriented patch. PARAMETER sets the
reverb time.
Again, but delay has a longer time, thus plays
'slower' and with longer samples.
Alters the pitch in real time. PARAMETER selects
one among four different transpose functions.
A real 'harmonizing' effect capable to add two
further voices to a monophonic source, panned
full left and full right.
Slightly alter the tuning of the source to simulate
a 'doubling' effect. PARAMETER controls the
frequency shift to make the effect subtler or more
noticeable.
As the previous one, basically, but with an
increased tuning alterations. Makes something
similar to a Chorus effect, great with guitars,
sometimes even more effective. PARAMETER
controls, of course, the frequency shift.
