5. OPERATION AND USAGE MANUAL

5.1 Start-up

To switch the mixer on push the switch labelled POWER (54) located in the rear panel - the two bottom Vu-meter,
ON leds will light up. Although the switching noise produced by the NUO5 is very low and almost inexistent when
starting up the NUO5 with the main faders down, we highly recommend the "safe power-up sequence", which
means that you should switch on your audio devices in the following order:
1. Sound sources.
2. Mixer, equalizers, active filters.
3. Finally, power amplifiers.
Powering off should be done by following the exact reverse sequence in order to avoid any possible damage to the
loudspeakers.

5.2 Control Description

5.2.1 Input selector
Each channel features an input toggle switch selector (1).
5.2.2 Channel GAIN
All the NUO5 input channels have an accessible input sensitivity GAIN control (4). The GAIN controls adjust the
input level of each channel in order to compensate the different sources connected to the mixer. All input sensitivity
adjustments must be done very carefully using the Input SP (Signal Present) (3) and PEAK leds (2), the VU-
METER, and/or headphones as a reference. The standard level reference used to mix audio signals is 0dBV. To
optimize your mix, adjust your input the closest to 0dBV on the PFL Vu-meter and never reach the "clipping" level
using the red "warning" PEAK led as a reference for each channel.
5.2.3 Equalization
The rotary tone controls for each channels provide a +10/-30dB boost/cut at high (5) and low frequencies (7) and
+10/-25dB at the mid range (6). This great attenuation range is specially designed for creative live performance.
Also the bass frequencies can be "killed on the fly" activating the BASS OFF switch (8) located below each BASS
rotary knob (except MICRO channel).
ATTENTION: Use equalization carefully, by boosting too much the low frequency range, you can induce an
excessive displacement of the speakers membrane.

5.2.4 Monitoring System

The NUO5 is equipped with a flexible and easy monitoring system that will allow the performers to finely tune
PFL/FX Cue (Pre-fader listening and Effect monitoring) and MIX (MIX Program Monitor) levels of the main inputs
through the VU-METER and the HEADPHONES.
Each channel as well as the effect processing can be monitorized visually and pre-listened pressing the dedicated
PFL (9) and/or FX CUE (30) yellow led button.
For HEADPHONES monitoring, the PFL/MIX rotary potentiometer (19) allows you to blend a selected PFL together
and/or FX CUE with the main MIX Program. The VOL rotary potentiometer (20) controls the level of headphones
output.
The NUO5 can display (38) at the same time PFL R+L signal (on the first left VU-METER bar) together with the
OUT 1 Right and Left signals ( second and third VU-METER bars).
