5. CONSIDERATIONS

5.1. Ground loops

Ensure at all times that no signal sources reaching the mixing desk and no devices connected
to its output have their earths interconnected; that is, earth should never reach them via two or more
different paths, as this could lead to humming which could even interfere with sound reproduction
quality. In order to avoid earth loops, ensure that the shielding of cables, if connected to the chassis,
are never connected with each other.

5.2. Audio connections

As a general rule of thumb, make the signal connections as short as possible and use the
best connectors and cable available. Cables and connectors are frequently held cheap, forgetting
that a bad connection can result in a poor sound quality. Use low capacity cables

5.3. Noise

The use of active circuitry can yield, depending on the configuration, to a significant noise
level. The SCLAT 200vs mixer has been designed for the minimum possible noise. Anyway, the
noise level will always depend on the correct use and installation of the mixer.
It is not the same setting up the FADER at "2" and the MASTER at "10" that the other way
round; FADER at "10" and MASTER at "2". In the first case you get a poor signal to noise ratio that
will be fully amplified by the master while on the second case we have a good signal to noise ratio
only amplified by "2". As a result, the background noise is greater in the first case than in the second
one.

5.4. Cleaning

The front panel should not be cleaned with dissolvent or abrasive substances because silk-
printing could be damaged. To clean it, use a soft cloth slightly wet with water and neutral liquid soap;
dry it with a clean cloth. Be careful that water never gets into the unit through the holes.
