4INPUT FROM MIXER

When the LED is OFF, the digital mixer is disabled and the signal input is coming from the XLR input 1 . In this case the male XLR output works as a regular parallel audio output. 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).

5 FLAT / BOOST switch

FLAT (released switch, normal mode): no equalisation is applied (flat frequency response).

BOOST (pushed switch): ‘loudness’ equalisation, only recommended for background music at low volume levels.

6 LIMITER LED

The internal amplifier is provided with a limiter circuit to prevent clipping and overdriving transducers. It blinks when the signal level reaches the clipping point, causing the limiter intervention. If it is steady lit, the input signal level is excessive and should be reduced.

7 SIGNAL LED

When lit, it indicates the signal presence at the audio input.

8 STATUS LED
When blinking, it indicates the internal protection intervention due to thermal drift (the
amplifier then gets to a “mute” status).	7

A dedicated box MP ON/OFF permits to turn on and off this feature.

The STEREO box ON/OFF allows to select the chosen system configuration: using the EVOX JMIX8 as a stand alone speaker, the STEREO box has to be set to OFF. Using EVOX 8 JMIX8 + EVOX J8 as a stereo configuration, the STEREO BOX has to be set to ON. In

ENGLISH

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 round point on the knob scale indicates the 0.0dB level.

MAIN GEQ page: this page gives access to the 7 band Graphic EQ available on MAIN channel. Select each single band of the EQ using the “PARAMETER SELECT” buttons

[ 12 ] and rotate the EDIT encoder to change value. A value box shows the variation in dBs 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).
