(37) The GND connectors are used for grounding turntables.
(38) The MIC AUX signal, adjustable using the AUX controls on the microphone channels (see (3)),
is laid out at this SEND jack connector. For example, the input of an external reverb can be
connected here.
(39) An external stereo effects signal can be fed back into the mixer using the RETURN L/R jack
connectors. If you connect a mono effects signal, you need to use the left RETURN L connector.
The effect volume can only be adjusted on the output control of the effects unit.
(40) The balanced MAIN 1 XLR outputs are used for connecting a power amplifier. Use the VOL
1 control to adjust the volume (see (16)).
(41) Hitting the MONO key changes the stereo MAIN 1 output signal into a mono signal. Doing this
makes sense when you for example use your PRO MIXER in large rooms where the speakers
are placed far from each other. A stereo signal would have a disrupting effect, since the
speakers each transmit a somewhat different signal. If you press MONO, an identical signal is
transmitted to both MAIN 1 outputs. The BAL 1 control (see (18)) has no function here.
(42) You can connect an additional amplifier to the SUBWOOFER output in order to drive a passive
subwoofer. If you wish to use an active subwoofer, connect it directly to this output. Either
way, you get more bass power out of your music.
(43) Use the LEVEL control to adjust the volume of the SUBWOOFER output signal
(44) Use the X/O control to adjust the upper cut-off frequency of the SUBWOOFER signal (adjustable
between 30 and 200 Hz). All frequencies with values below the cut-off frequency will
be reproduced.
(45) The MAIN 2 output allows you to connect an amplifier to drive monitor speakers or to provide
sound in another room/area ( zone ). The VOL 2 control (see (17)) adjusts the MAIN OUT
section.
(46) Using the TAPE output, you can record your music by connecting equipment such as tape
decks, DAT recorders etc. Unlike the MAIN outputs, the output volume is fixed, making it necessary
for you to adjust the input level on the recording device.
(47) Your PRO MIXER features an effects loop that can be used for an external effects unit or a
sampler. The signal is taken at the PFL section through the SEND connector and fed into
your external equipment. The signal laid out at the SEND connector is therefore identical to
the headphone signal. Connect this output to the input of your effects unit.
