3. Instructions for use and installation
1. Protection and maintenance.
To avoid jeopardizing correct operation, it is best not to
position the effect for long
periods in exposed places
(damp, high temperature, etc.), in dusty environments or
those subject to strong vibrations. Do not force knobs,
switches or faders: they have been designed to respond
to a light touch and could be damaged if treated with
excessive force. In the event of breakdown, do not open
the effect, but contact the nearest GENERALMUSIC
Service Centre.
2. Prevention of possible interference.
First of all, check that the mixer is installed in a place
free from industrial or RF (radio frequency) interference.
Avoid installing your equipment very near radio or TV
sets, mobile phones, etc., as these can cause noisy
interference.
3. Connections.
Before connecting the mixer to the mains socket, always
make certain that the electric system and mains socket
have an adequate grounding, compatible with the safety
norms. Be sure also that the mains voltage corresponds
to that shown on the rear of the unit (an allowance of
up to ±10% is accepted) and that the power cord is not
damaged and has no bare wires. It is best to connect the
effect after switching it on and lower (or better still close)
the output levels of the mixer channel: this avoids annoying
and sometimes dangerous (particularly for the speaker
cabinets) signal peaks.
4. Connector cables.
When connecting loudspeaker systems to the mixer’s
power outputs, make certain to always use only
power cables made up of just two wires with the same
cross-section: the use of signal cables could cause an
excessive loss of power. Check periodically that your
cables are in good condition, correctly wired and with
perfectly effi cient contacts: in fact many problems and
drawbacks (false contacts, ground hum, crackles, etc.)
are caused by the use of unsuitable or damaged cables.

1. POWER
To switch on off the effect, when it is switched on the
button is lighted. We suggest to switch on the effect
before the mixer or therefore with the channel in mute
condition.
2. PRESETS
It is the DSP’s PRESET selector: allows to select the
desired effect among 16 PRESETS: several kinds of
reverbs, stereo delay, chorus and 2-effect combinations
(reverb + delay, reverb + chorus).
3. VARIATIONS
Allows to select the desired variation (decay, depth,
harmonic content, etc.) among 16 VARIATIONS of the
selected PRESET. The choice of 16 VARIATIONS for
each PRESETS allows up to 256 different effects to
be available. The main parameters of each effect are
listed in the PRESET LIST table.
4. INPUT
It sets up the amplifi cation of input signal. We suggest
to adjust it since the peak led remains off or fl ashes
irregular.
5. MIX
It sets up the portion of effected sound (WET position)
regards to natural sound (DRY position).
6. OUTPUT
It sets up the amplifi cation of output signal.
7. LED PEAK/MUTE
This LED shows 2 conditions:
• lighted = shows that the effect is MUTED.
• fl ashing = shows a too high signal level, near to the
overload. In this case, try to reduce the effect's input
signal acting on the INPUT control.
5. Rear Panel (fi g. 2)
8. INPUT
Unbalanced JACK connector that receives the LINE
input signal. It can be used with all equipment capable
of high level signal output.
9. OUTPUT (right)
Unbalanced JACK connector that sends only the right
channel signal. It can be used with all equipment
capable of high level signal input.
