Audio Monitoring System; Security Caps; Ground Loops, Background Noise; Inputs And Zones Identification - Ecler MIMO54 Notice D'utilisation

The same cable type is used to connect a MPAGE4 unit (optional) to the MIMO54 PAGER
connector (23).

6.7. Audio monitoring system

Use the MONITOR section to monitor the sound volume and content for output zones and Input
#5, as described in section 5.2. Phones output.

6.8. Security caps

The unit is supplied with security caps that are very useful accessories to prevent unwanted
manipulations of front panel rotary knobs after commissioning. To use these caps, smoothly remove the
rotary knobs and replace them with the provided caps.

6.9. Ground loops, background noise

You should always make sure that signal sources feeding the unit as well as all devices
connected to its outputs do not have their grounds interconnected. To resume, ground must never come
from two different paths. Should this ever happen, noises could occur and seriously affect the sound
quality.
Cable shields, when connected to the chassis, must never be interconnected so as to avoid
ground loops.
This equipment has been designed for the lowest possible background noise. Independently of
the electronic design itself, total background noise level will directly depend on the correct installation
and use of all units in the audio chain.

6.10. Inputs and zones identification

On the front panel, there are spaces (1) dedicated for label writing in order to easily identify
inputs and assigned zones.

6.11. 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.
