ART48 - STEREO IN
The UNIT ON button(7.) connects or disconnects the output routing
for all outputs (AUX 1, AUX 2, AUX 3 and L/R), with the exception of
the PFL routing. This function is similar to the MUTE button found
on other mixers, except that its functionality is reversed: When the
UNIT ON button is depressed, all outputs are connected (whereas a
MUTE button in its depressed position disconnects the output). Also,
a MUTE normally only disconnects the L/R routing (the channel’s
fader), whereas this module’s UNIT ON button affects all outputs.
Being able to switch off a channel strip makes sense: For example, it
prevents a signal from still going through to stage monitors, or to the
input of the reverb unit.
THE AUXILIARY SENDS
You will nd the auxiliary sends, labeled STEREO AUX SENDS(8.),
just above the UNIT ON button. There are three knobs for the left
level control of each send (AUX 1, AUX 2, AUX 3) and three knobs for
the right (AUX 1, AUX 2, AUX 3). Therefore, every single AUX send
can be controlled independently from the other sends and from the
other left or right channels.
What’s more, the unit enables every AUX send to “read” the signal
either pre or post fade, courtesy of the Pre / Post buttons(9.) located
near the respective AUX level controls.
If a button is not depressed (orange light), it means that the signal will
arrive “post fade”. When in this position, the relevant auxiliary level
will obviously be controlled by its level knob, but the nal outcome
will also be inuenced by the channel fader’s position. This is very
useful when driving a reverb unit for example, where the proportion of
reverb to original (dry) signal is set by the level knob, then maintained
in proportion while any overall level changes are made using the
channel fader.
If a button is depressed (blue light), the signal will arrive “pre fade”: In
other words, it will be sent to the AUX master without being inuenced
by the position or movement of the channel fader. This conguration
will normally be chosen when driving stage monitors (or similar
devices) through the respective auxiliary master, where inuence
from the main channel fader is not required.
Note: As well as the L/R Master unit, you will also need the AUX Master
unit to benet from all the AUX sends (and other additional options).
The L/R Master can only receive AUX 1, but this is just intended as
a basic conguration where, for example, only one auxiliary send is
needed to operate a reverb device and no stage monitors are being
used.
This AUX Master unit also offers a CLASS-A headphone output,
