MASTER output
This stereo output feeds the PA system through balanced XLR3 connectors (32, 33) and an unbalanced RCA
connector (34). The nominal level for MASTER output is set to 0dBV (1V), but can be set to +6dBV using an
internal jumper. The MASTER output level is controlled by the MASTER potentiometer (16).
Near the MASTER controller you will find the L+R switch (19), which adds the left channel and the right channel for
MASTER and BOOTH outputs. This function is especially useful if a failure occurs on one of the channels during a
live session (a typical example could be a bad contact in the turntable's capsule). Enabling this switch, the mixer
will send the L+R sum to both loudspeakers, so that the major part of the audience will not notice the malfunction.
MASTER and BOOTH have a balance controller BAL (21)
BOOTH output
Commonly used as an independent local "Booth" output for the DJ. This stereo BOOTH (35) has unbalanced RCA
connections and its level is set at 0dBV (1V) but can be changed to +6dBV (2V) through internal jumpers. The
BOOTH level controlled by the BOOTH (17) potentiometer.
Record output
There is a REC output (13) on the control surface, which uses RCA connectors. The nominal output level for the
REC output is 0dBV (1V). This output is taken post-fader, before the MASTER signal.
FX Send/Return effects loop
The RCA connectors on the FX SEND output (39) and the FX RETURN input (40) allow creating a signal loop for
external effects processors, samplers or sequencers. The nominal level for the SEND output, as well as for the
RETURN input, is 0dBV (1V).
The signal sent to the FX SEND output can be taken before or behind the fader using the PRE/POST switch (9)
and the send level can be set using the associated potentiometer (8). The NUO3.0 also wears a general FX
RETURN controller (20) and a controller for the FX RETURN monitoring signal, FX PFL (18).
Headphones
In order to obtain a high performance, these should be of the high impedance type (200-600Ω). Plug them to the
output (30), in the front panel, by means of a standard 1/4" stereo jack. Sleeve is Ground, Ring is Right Channel
and Tip is Left Channel.
