2.3 Connector panel and main section

    Whereas it was useful to trace the signal flow from top to bottom it order to gain an understanding of 
the channel strips, we now look at the mixing console from left to right.  The signals are, so to speaker, 
collected from the same point on each of the channel strips and then routed to the main section all 

together.

   A channel signal is routed to aux send bus 1 if the Aux 1 
control is turned up on the corresponding channel.

    The AUX SEND control MON acts as master control 

for auxsend 1 and determines the level of the summed 

signal.

AUX SEND 1 (MON)

    Similarly, the FX control (AUX SEND 2) determines 
the level for aux send 2.

    You can use the SOLO switch to separately monitor the aux sends via the CONTROL ROOM/PHONES 
outputs and check these with the level metres.

AUX SENDS

If you want to monitor the signal the of just one AUX bus, none of the other SOLO SWITCHES
should  be pressed and the MODE switch must be in the SOLO position (not pressed down).

AUX SEND 1

AUX SEND 2

    If you use aux send 1 pre-fader, you would usually 
connect the AUX SEND 1connector to monitors via a 
power amp (or an active monitor system). If you use aux 
send 1 post-fader, proceed as described under aux send 2.

    The AUX SEND 2 connector outputs the signal you picked up from the individual channels using the 
FX control. You can connect this to the input of an effects mix is created, the processed signal can then 
be routed from the effects device output back into the STEREO AUX RETURN connectors.

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

MAIN MIX

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

PHONES/CTRL (ROOM)

    When the 2-TRACK TO MAIN switch is depressed, the 2-track input is routed to the main thus serves 
as an additional input for tape machines. You can also connect MIDI further processing. At the same time, 
this switch disables the main mix to tape output link.

2-TRACK TO MAIN

POWER

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

LEVEL METER

    The high-procision level meter accurately displays the appropriate signal level. 

+48V

    The red “+48V” LED lights when the phantom power supply is switch 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/wellbox) while the phantom 
power supply is switched on. Connect microphones 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.

    When recording to a digital device, the recorder  ’ s peak metre should mot exceed 0 dB. This is because, 
unlike analog recordings, slightly excessive levels can create unpleasant digital distortion.

LEVEL SETTING

    When recording to an analog device, the VU meters of the recording machine should reach approx. 
+3 dB with low-frequency signals (e.g. Kick drum). Due to their inertia VU meters tend to display too low 
a signals level at frequencies above 1 kHz. This is why ,for example, a Hi-Hat should only be driven as 
far as  -10dB. Snare drums should be driven to approx. 0 dB.

The peak metres of your XENYX display the level virtually independent of frequency. A 
recording level of 0dB is recommended for all signal types.

PFL

    To activate the PFL function, depress the MODE switch. The PFL function should, as a rule, be used 
for gain setting purposes. The signal is sourced pre-fader and assigned to the mono PFL bus. In the “PFL” 
setting, only the left side of the peak meter operates. Drive the individual channels to the 0 dB mark of 
the VU meter.

SOLO

    When the MODE switch is not depressed, the stereo solo bus is activate. Solo is short for “Solo In 
Place”. This is the customary method for listening to an individual signal or to a group of signals. 

As soon 

as a solo switch is pressed, all channels in the control room (and headphones) that have not been 
selected are muted thereby retaining stereo panning. The solo bus can carry the output signals of the 
channel pan controls, the aux sends and the stereo line inputs. The solo bus is, as a rule, switched post-
fader.

MODE

    The MODE switch determines whether the channels’ SOLO switch operates as PFL (Pre Fader Listen) 
or as solo (Solo In Place).
