MASTER output
This stereo output feeds the PA system through balanced XLR3 connectors (38, 39) and an unbalanced RCA
connector (40). 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 (24).
Near the MASTER controller you will find the L+R switch (27), 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 (26)
BOOTH output
Normally this is used to obtain an independent output for the DJ booth. This stereo BOOTH output wears a
balanced XLR3 output and an unbalanced RCA output. The nominal level for the BOOTH output is set to 0dBV
(1V), but can be adjusted to +6dBV using an internal jumper. The BOOTH output level is controlled by the BOOTH
potentiometer (25).
Record output
There is a REC output (22) 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 (41) and the FX RETURN input (42) 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 NUO4.0 also wears a general FX SEND
controller (17), which adds the four channels, a general FX RETURN controller (15) and a controller for the FX
RETURN monitoring signal, FX PFL (16).
Headphones
In order to obtain a high performance, these should be of the high impedance type (200-600Ω). These are to be
connected to the headphones output (30) located on the controller surface using a stereophonic, normalized ¼''
jack connector or a 3.5mm minijack connector. Sleeve is Ground, Ring is Right Channel and Tip is Left Channel.
