2.4 AUX 1/2

Generally, the AUX 1/2 channel is used for the connection of an additional, external FX unit. De- pending on the setting of the AUX 1/2 POST button, it is also possible to configure the bus for monitoring purposes. Additionally the AUX 1/2 channels are available at the DIGITAL AUDIO IN-

TERFACE.

38 - AUX 1/2 SENDS

This output provides connection for an external FX unit or, when used for monitoring, a power amplifier or active stage monitor speaker systems. Using the AUX 1/2 fader allows setting the out- put level in a wide range up to +20 dBu. The AUX 1/2 SEND is designed in Ground Sensing tech- nology to prevent the induction of external noise, even with long cables. Use balanced cables for the connection of external components whenever it is possible.

39 - AUX POST

As already previously described, this switch allows determining whether Pre- or Post-Fader sig- nals are present at the AUX 1/2 channel. The corresponding yellow LED signals when the switch is engaged and all input channel AUX 1/2 controls are assigned post fader.

40 - MUTE

The MUTE button mutes the AUX output signal. PFL signals are not affected.

41 - PFL

Through this button you can route the pre AUX 1/2 fader signal to the headphones bus. The signal is outputted for listening via the headphones output. The setting of the AUX 1/2 fader is not rel- evant for the signal’s volume (Pre Fader Listen). The meter instrument in the master section is simultaneously switched, so that the left LED-chain indicates the level of the actually chosen channel (in dBu), leaving you with the opportunity for adjusting the level without routing it to the AUX 1/2 SEND bus.

42 - AUX 1/2 FADER

This fader controls the summed audio signal at the AUX 1/2 SEND output. When used for moni- toring, this fader lets you control the volume of the monitor system. When using the DIGITAL AU- DIO INTERFACE for recording this fader also controls the volume of sent channels USB 3 or USB 4. See page 21 for details about using the DIGITAL AUDIO INTERFACE.

2.5 MON 1/2

43 - MON 1/2 OUTPUTS

This output provides connection for an power amplifier or active stage monitor speaker systems. Using the MON 1/2 fader allows setting the output level in a wide range up to +20 dBu. The elec- tronically balanced XLR-type outputs are in parallel to the phone-type outputs. Using the XLR- type and (monaural or stereo) phone-type outputs simultaneously is possible for connecting more than one active stage monitor speaker system.

44 - FEEDBACK FILTER

The feedback filter is a very narrow banded notch filter, which is only active in a range that is extremely susceptible for acoustical feedback. The FEEDB. FILTER rotary control sets the corre- sponding frequency range. Pressing the corresponding button activates the filter. Several circum- stances and conditions have an influence on how sensitive or insensitive your system is for acoustical feedback. The following notes are meant to assist you in avoiding feedback and you should take them into consideration even before you activate the feedback filter.
