2.5 Mono out section for
subwoofer applications
Using this auxiliary mono output you can route the main mix signal to a separate
power amp. The tunable low-pass filter allows you to limit the signal content to
the low-frequency range to get a perfect subwoofer signal. This signal is mono
because very low frequencies disperse quickly, so there would be no benefit to
position this signal in the stereo mix.

Fig. 2.11: Mono out fader and low-pass filter
(29)
The
MONO
fader controls the volume of the signal present at the
MONO OUT (see
(32)
).
(30)
The FREQ control adjusts the cut-off frequency of the low-pass filter
(30 to 200 Hz). Frequencies above cut-off are filtered out when activated.
(31)
Use the
LOW PASS FILTER
switch to activate the filter function (LED illuminates).

fig. 2.12: Mono out connector
(32)
The MONO OUT connector provides the line-level mono signal for
connection to the inputs of a power amp or active speaker. You can also use
this output as a monitor bus, e.g. to connect a headphone amplifier. In this
case, the signal should of course not be limited by the low-pass filter.
2.6 Main out section

Use this high-precision MAIN fader to control the output level of the main mix.
(34)
Fig. 2.14: XLR main out connectors
(34)
The
MAIN OUT
(puts) are balanced XLR connectors with a nominal operating
level of +4 dBu and provide the main mix signal.
(35) (36)
Fig. 2.15: Main out connectors and main insert
(35)
The
MAIN OUT
¼" TRS connectors outputs also provide the main mix signal.
(36)
Like the channel inserts, the MAIN INSERT connectors can be used to
connect a dynamics processor or equalizer for further processing of the
mix signal. The MAIN INSERT refers to the Main Outs (XLR and ¼" TRS
connectors), the MONO OUT (see
(32)
) and, if the MAIN switch in the
PHONES/CONTROL ROOM section is pressed, also to the PHONES/CTRL ROOM
output (see
(46)
).

The red “ +48 V ” LED illuminates when phantom power is on.
Phantom power is required for the operation of condenser microphones,
and can be switched on with the corresponding switch on the rear of
the console.
(38)
The POWER LED is illuminated when the console is switched on.
(39)
The high-precision level meter accurately indicates the output signal level.
For example, when you press the SOLO switch on one of the input channels,
its signal level will be displayed here, either pre-fader (PFL) or post-fader
(SOLO), depending on the position of the SOLO/ PFL switch (see
(40)
). In PFL
mode only the left display is active, because the PFL signals are mono.
