Considerations; Ground Loops, Background Noise; Cleaning - Ecler 2VSP-RS Manual De Instrucciones

5. CONSIDERATIONS

5.1. Ground loops, background noise

You should always make sure that the signal sources coming to the unit, as well as all devices
connected to its outputs, do not have their grounds interconnected, that is; ground must never come from
two different devices. Should this ever happen, noises could occur and seriously interfere the sound quality.
Cable shielding, when connected to the chassis, must never be interconnected, so as to avoid
ground loops.
The 2VSP has been designed for the lowest possible background noise. Independently from the
electronic design itself, background noise level will directly depend on the right installation and use of the
unit.

5.2. 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 of the front panel.
