This output is linked in parallel with the audio input and is useful to connect another
speaker (only when the INPUT FROM MIXER
default as the mixer “R” output channel.
INPUT FROM MIXER
When the LED is OFF, the digital mixer is disabled and the signal input is coming from the
XLR input
When the LED is ON, the signal input is coming from EVOX JMIX8 digital mixer. In this
case, the male XLR output becomes by default the R output to an addictional EVOX J8.
(The mixer offers a function (SWAP LR) to swap the L-R output channels swapping them
to “R-L”;
See section 11 on the Digital Mixer Instruction Chapter).

this case the EVOX JMIX8 outputs the LEFT channel and the EVOX J8 outputs the RIGHT
channel. If the environment or the setup does not permit the correct positioning of EVOX
JMIX8 as left channel and EVOX J8 as right channel, it is possible to reverse the stereo
image using the box called SWAP LR:
SWAP LR OFF: EVOX JMIX8 LEFT – EVOX J8 RIGHT
SWAP LR ON: EVOX JMIX8 RIGHT – EVOX J8 LEFT
EQLIVE
This control enables a specific contour which is optimized for live use of musical
instruments, rather than prerecorded material. You can enable this mode at your choice.
The EQLIVE setting affects both LEFT and RIGHT outputs, therefore it is activated also
on the external EVOX J8 which may be connected to the LINK OUT XLR output; the AUX
output is not affected, unless its routing is set to Link Out mode.
A MUTE box completes the set of controls on this page. Selecting the MUTE box
interrupts the signal flow through the MAIN stereo channel. The numeric window in the
lower right display corner shows the nominal level of the MAIN LEVEL knob. The small

of the selected band. A dedicated box permits to turn ON and OFF the entire EQ.
AUX OUT page: this page gives access to the master level control of the AUX bus. Select
“AUX” from the ROUTING drop-down menu for the regular use of the AUX send. PRE/
POST ON/OFF box allows to derive the AUX signal before or after the channel level
control. Set this control to OFF for AUX PRE and ON for AUX POST. FX RTN ON/OFF box
permits to assign the internal effect return to the AUX bus. The MUTE box, if selected,
mutes the AUX bus output.
Select “MAIN L-R” from the ROUTING drop-down menu, permits to assign to the AUX
bus the MAIN MIX signal, summed in mono.
Select “LINK OUT” from the ROUTING drop-down menu, it allows to create an available
link connection with a further EVOX J8 from the AUX OUT balanced jack. This setting
permits to create a large EVOX setup composed by one EVOX JMIX8 plus up to three
EVOX J8. (See page 42: EVOX JMIX8 CONFIGURATION).
