Mono out section for subwoofer 2.5
applications
Using this auxiliary mono output you can route the main mix signal
to a separate power amp. The tunable low-pass lter 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 frequen-
cies disperse quickly, so there would be no benet to position this
signal in the stereo mix.
Mono out fader and low-pass lterFig. 2.11:
(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 lter (30 to 200 Hz). Frequencies above cut-off are
ltered out when activated.
(31) Use the LOW PASS FILTER switch to activate the lter
function (LED illuminates).
Mono out connectorFig. 2.12:
(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 amplier. In this case, the signal
should of course not be limited by the low-pass lter.
Main out section2.6
Main out faderFig. 2.13:
(33) Use this high-precision MAIN fader to control the output level
of the main mix.
XLR main out connectorsFig. 2.14:
(34) The MAIN OUT(puts) are balanced XLR connectors with a
nominal operating level of +4 dBu and provide the main mix
signal.
Main out connectors and main insertFig. 2.15:
(35) The MAIN OUT 1/4" 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 1/4" 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)).
Level meterFig. 2.16:
(37) 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.
(40) The SOLO/PFL switch determines whether the monitored
signal is pre (PFL) or post-fader (SOLO) after pressing the
SOLO/PFL switch (the LED illuminates). The level meter
indicates the corresponding signal (see (39)). When you
adjust a signal with the TRIM control, it is advisable to select
PFL mode, so that the level shown is independent of the
channel fader position.
