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 find 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 final outcome 

will also be influenced 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 influenced 

by the position or movement of the channel fader. This configuration 

will normally be chosen when driving stage monitors (or similar 

devices)  through  the  respective  auxiliary  master,  where  influence 

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 benefit 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 configuration 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,
