Warnings and Installation

✔

Connection to the mains supply

The unit has its own built-in power supply. Before switching on the unit, make certain that the mains voltage
matches that shown on the rear (a tolerance of up to ±10% is acceptable). Before connecting or disconnecting
the power cord, make certain the ON/OFF switch is in the OFF position.

✔

Switching on and off

CAUTION: before switching on or off, make certain that the sound system’s amplifiers are off or that all unit’s
outputs are automatically forced into

MUTE

status: this will avoid signal peaks, which are annoying and

sometimes dangerous (particularly for speaker enclosures).

✔

Connecting and preventing or identifying interference

First of all, check that the apparatus is installed in a place free from industrial or RF (radio frequency) interfer-
ence. Avoid installing your equipment very near radio or TV sets, mobile phones, etc., as these can cause
noisy interference. When connecting the other parts of your sound system, watch out for the so-called “ground
loops”, which could cause hum and jeopardize the products’s excellent Sound-to-Noise and low distortion
characteristics.
The best way (even if not always feasible) to avoid ground loops is to connect the electric ground of all the
equipment to a single central point (“star” system). In this case, the central point can be the mixer.

✔

Protection and maintenance

Don’t force knobs or switches: these are designed and manufactured to respond to light pressure and could
be damaged if used with excessive force. Take care of your connector cables, a very frequent cause of small/
big problems. Always grip them by the connector, avoid pulling them forcefully and wind them without forming
knots or sharp bends: they’ll last longer this way, and be more reliable, which is a definite advantage.
Avoid exposing the product to strong direct sunlight, high temperatures or intense vibrations, in very dusty or
particularly damp surroundings or, even worse, in the rain: this will help to avoid the risk of faulty operation,
deterioration or even electric shocks and fires. The product is built in shock-resistant material. Nevertheless,
protect it during transport with a flight-case to avoid the risk of any casual accidents. When you’ve finished
using the apparatus, it’s always advisable to protect it from dust, but any dust that does form should be
removed using a cloth or a soft brush. Never use alcohol, acetone or any solvents. The effect does not require
any other maintenance.

✔

In the event of breakdown

All user-adjustable parts are external and easily accessed. In the event of a breakdown, do not open the
apparatus, but contact the nearest

Generalmusic/Lem Service Centre

✔

Keeping the documentation

Keep this user’s manual for future consultation. Also remember that the effect will get a better price on the
secondhand market if (as well as being in good condition) it has its original documentation and packaging.
