Routing switch, solo and channel fader

PAN
The PAN control determines the position of the channel
signal within the stereo image. This control features a
constant-power characteristic, which means the signal
is always maintained at a constant level, irrespective of
position in the stereo panorama.
MUTE/ALT 3-4
You can use the MUTE/ALT 3-4 switch to divert the
channel from the main mix bus to the Alt 3-4 bus.
This mutes the channel from the main mix.
MUTE-LED
The MUTE LED indicates that the relevant channel is
diverted to the submix (Alt 3-4 bus).
CLIP-LED
The CLIP LED lights up when the input signal is driven
too high. In this case, turn down the GAIN control and,
if necessary, check the setting of the channel EQ.
SOLO
The SOLO switch (1204FX only) is used to route the channel signal to the solo bus
(Solo In Place) or to the PFL bus (Pre Fader Listen). This enables you to monitor a
channel signal without affecting the main output signal. The signal you hear is
sourced either before (PFL, mono) or after (solo, stereo) both the pan control and
the channel fader (see chapter 2.3.6 "Level meters and monitoring").
The channel fader determines the level of the channel signal in the main mix
(or submix).

Stereo channels

2.2.1

Channel inputs

Each stereo channel has two balanced line level inputs
on ¼" connectors for left and right channels. If only the
connector marked "L" is used, the channel operates in
mono. Stereo channels are designed to handle typical
line level signals.
Both inputs can also be used with unbalanced jacks.
LEVEL
For level matching, the stereo inputs feature a LEVEL switch which selects
between +4 dBu and -10 dBV. At -10 dBV (home-recording level), the input is
more sensitive than at +4 dBu (studio level).
2.2.2

Equalizer stereo channels

The equalizer of the stereo channels is, of course, stereo. The filter characteristics
and crossover frequencies are the same as those of the mono channels. A stereo
equalizer is always preferable to two mono equalizers if frequency correction of a
stereo signal is needed. There is often a discrepancy between the settings of the
left and the right channels when using separate equalizers.
2.2.3

Aux sends stereo channels

In principle, the aux sends of the stereo channels function in just the same way as
those of the mono channels. As aux send paths are always mono, the signal on a
stereo channel is first summed to mono before it reaches the aux bus.
2.2.4 Routing switch, solo and channel fader
BAL
The function of the BAL(ANCE) control corresponds to the PAN control in the
mono channels.
The balance control determines the relative proportion between the left and
right input signals before both signals are routed to the main stereo mix bus.
The MUTE/ALT 3-4 switch, the MUTE-LED, the CLIP-LED, the SOLO switch and the
channel fader function in the same way as the mono channels.
2.3

Connector panel and main section

Whereas it was useful to trace the signal flow from top to bottom in 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 speak, collected from the same point on each of
the channel strips and then routed to the main section all together.
2.3.1

Aux sends 1 and 2

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

routing controls
AUX SEND 1 (MON)
The AUX SEND control MON acts as master control for
aux send 1 and determines the level of the summed
signal. In the 1204FX, the MON control is called
AUX SEND 1.
AUX SEND 2 (FX)
Similarly, the FX control (AUX SEND 2) determines the level for aux send 2.
SOLO
You can use the SOLO switch (1204FX only) to separately monitor the aux sends
via the CONTROL ROOM/PHONES outputs and check these with the level meters.
If you want to monitor the signal 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).
2.3.2

Aux send connectors 1 and 2

AUX SEND 1
If you use aux send 1 pre-fader, you would usually
connect the AUX SEND 1 connector to monitors via a
Fig. 2.5: Stereo channel
inputs and LEVEL switch
power amp (or an active monitor system). If you use
aux send 1 post-fader, proceed as described under
aux send 2.
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 device in order to process the FX bus signal. Once an
effects mix is created, the processed signal can then be routed from the effects
device output back into the STEREO AUX RETURN connectors.
