STEREO AUX RETURN MON

The STEREO AUX RETURN MON control has a special function: it can be used to add an effect to a monitor mix. For example:

Monitor mix with effect

In this instance, the effects device should be set up as follows: AUX SEND 2 is connected to the L/Mono input of your effects device, while its outputs are connected to STEREO AUX RETURN 1. Connect the amplifier of your monitor system to AUX SEND 1. The AUX SEND 1 master control determines the volume of the monitor mix.

You can now use the STEREO AUX RETURN MON control to adjust the level of the effects signal routed to the monitor mix.

You can easily use the headphones distribution amplifier BEHRINGER POWERPLAY PRO HA4700/HA8000 to provide you with four (or eight with the HA8000) stereo headphone mixes for your studio.

STEREO AUX RETURN 2 (FX)

The STEREO AUX RETURN 2 control determines the level of signals fed into the AUX RETURN 2 connectors which are routed to the main mix.

MAIN MIX/ALT 3-4

The MAIN MIX/ALT 3-4 switch routes the signal connected to STEREO AUX RETURN 2 to either main mix (not pressed) or submix (Alt 3-4, pressed).

2.3.5 2-Track input/2-Track output

Fig. 2.10: 2-track connectors

2-TRACK INPUT

The 2-TRACK INPUT RCA connectors are provided for connecting a 2 track machine (e.g. DAT recorder). They can also be used as stereo line input. Alternatively, the output signal of a second EURORACK or BEHRINGER ULTRALINK PRO MX882 can also be connected. If you connect a hi-fi amplifier with a source selection switch to the 2-TRACK INPUT, you can easily switch between additional sources (e.g. cassette recorder, CD player, etc.).

2-TRACK OUTPUT

These connectors are wired in parallel with the MAIN OUT and carry the main mix signal (unbalanced). Connect the 2-TRACK OUTPUT to the inputs of your recording device. The final output level can be adjusted via the high-precision MAIN MIX fader.

◊If you connect a compressor or a noise gate after the 2-track output, the faders will probably not be able to create a satisfactory fade-out effect.

2.3.6 Level meter and monitoring

Fig. 2.11: Control room/phones section, level meter

2-TRACK

The 2-TRACKswitch routes the signal from the 2-TRACK IN connectors to the level meter, the CONTROL ROOM OUT outputs and the PHONES connector this is a simple way to check recorded signals via monitor speakers or headphones.

ALT 3-4

Similarly, the ALT 3-4switch routes the signal from the Alt 3-4 bus to the same path for monitoring purposes.

MAIN MIX

The MAIN MIX switch sends the main mix signal to the above-mentioned outputs and to the level meter.

PHONES/CTRL RM

Use this control to set control room output level and headphones volume respectively.

2-TRACK TO MAIN

When the 2-TRACK TO MAIN switch is depressed, the 2-track input is routed to the main mix and thus serves as an additional input for 2-track machines. You can also connect MIDI instruments or other signal sources here that do not require any further processing. At the same time, this switch disables the main mix to 2-TRACK OUTPUT link.

POWER

The blue POWER LED indicates that the device is switched on.

+48 V

The red “+48 V” LED lights up when the phantom power supply is switched on. The phantom power supply is necessary for condenser microphones and is activated using the switch on the rear of the device.

◊Please do not connect microphones to the mixer (or the stagebox/ wallbox) while the phantom power supply is switched on. Connect micro-phones before you switch on the power supply.

In addition, the monitor/PA loudspeakers should be muted before you activate the phantom power supply. After switching on, wait approx. one minute to allow for system stabilization.
