Installation; Further Considerations; Ground Loops; Audio Connections - Ecler EVO5 Kurzanleitung

2. INSTALLATION

The EVO5 operates now with a new universal input power supply "Switching Power Supply" and can perfectly
works without any internal modification from 90V to 264V – 47 to 63Hz. Make sure that the mains-wire is far away
from the signal-cables in order to avoid any possible audio hum.
Because of the high gain of the PHONO and MICROPHONE inputs, always try to place the mixer as far away as
possible from noise sources (dimmers, engines, etc.) and mains wires. For the very same reason, and under any
circumstance, you should never remove the unit's metallic cover.
The power consumption of the EVO5 is very low, so they do not need any cooling, but you should avoid extreme
temperatures and the atmosphere should be as dry and dust free as possible.
In order to protect the unit from an eventual electrical overload it carries a T 1A fuse. Should it ever blow up, unplug
the unit from mains and replace it with an identical one. If the new fuse blows again contact immediately with our
authorized technical service.
ATTENTION: NEVER SHORT-CIRCUIT THE SECURITY PATH NOR USE A HIGHER VALUE FUSE.
CAUTION: Fuse substitutions have to be performed by a qualified technician.

3. FURTHER CONSIDERATIONS

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.

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.

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.
