Further Considerations - Ecler nuo 2.0 Manuel Utilisateur

6. Connect the multipin connector you disconnected before.
7. Fix it with the two screws. Make sure the orientation is the one described on the drawing.
8. Put the control plate back in place and screw it tight.
9. Put the potentiometer buttons back in place.

MASTER (16) level knob. The BOOTH level is controlled by the BOOTH (17) level knob.

6. 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.
Background noise
The use of active circuitry can yield, depending on the configuration, to a significant noise level. The NUO2.0 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 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.
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 control panel should never be cleaned with solvent or abrasive substances as it could become damaged. To
clean it, use a slightly moist soft cloth, together with a neutral liquid detergent, and then dry it with a clean cloth. It is
advisable to remove all sweat stains after use. Be careful to ensure that water never enters the machine through
any of the openings.
