Вот из вражеского мануала..К верхним четырем ручкам ауксов (обведены синим вверху)
AUX SENDS The combined effects signal can be returned to
Auxes 1 to 4. These sends are not affected by the ST1 (ST5) LEV
control which returns the signal to the LR mix. The stereo signal is
summed to feed the auxes in mono. This can be changed if preferred
by repositioning internal jumper options so that L feeds auxes 1,3, and
R feeds auxes 2,4. Use the aux sends to add the effects to the
monitors if required.

AUX MASTERS Each aux mix has a master level control that
adjusts the output level to match external equipment, or to trim the
monitor, effect or other send without affecting the mix balance. Up to
+4dB boost is available above the normal 0dB position.
Note that the AUX5 and AUX6 master controls do not affect the level
sent to the internal effects processor. They do affect the level
available at the rear panel aux output sockets.

Console Monitor Comprehensive engineer’s headphones monitoring
is provided. Select the source to listen to using the monitor switch
bank. With no switch pressed the post-fade LR mix is monitored.
Press M to listen to the post-fade M source. Pressing any switch
higher up the bank overrides the previous selection. Pressing ST1
(ST5) listens to the wet effects only return signal if the internal effects
processor is active. Pressing Aux pairs 1-2, 3-4, 5-6 together listens to
the two selected auxes as a stereo pair. The two console meters
display the selected monitor source signal level.
Pressing channel PFL switches automatically overrides the current
monitor selection with the pre-fade signal from that channel or
selection of channels. The red PFL active indicator lights and the
console meters display the channel signal.
We recommend you use closed ear headphones in the range 30 to
600 ohms designed for live sound monitoring. Headphones around
100 ohms impedance are a popular choice.
