CLIP LED
The CLIP LED lights up when the input signal is driven too high.
In this case, lower apparent frequency increase on the channel
EQ to avoid distortion. For example, lower the mids and the highs
somewhat to emphasize the bass. If you don’t wish to change
the EQ settings under any circumstances, try lowering the TRIM
control somewhat (counterclockwise).
If you inserted an external effects processor via the insert
connector (e. g. a dynamic processor), then you should also
control its output signal level. It should not be higher than its input
signal level (0 dB).
The channel fader determines the level of the channel signal in
the main mix.

Attention: Since the aux path for the effect processor
is connected post-fader, the channel fader has to
be turned up in order to get this channel’s signal to
the effects processor!
2.2 Stereo channels
2.2.1 Channel inputs
Fig. 2.5: Stereo channel inputs
Each stereo channel features two line-level inputs on 1/4"
connectors for left and right channels. Channels 9/10 and 11/12
can also be used in mono if you only use the connector labeled
“L.”
Both channels 5/6 and 7/8 feature an additional balanced XLR
input for microphones with available +48 V phantom power.
All stereo channel strips have a TRIM control for level setting.
In those channels in which a mic input is present in the channel,
the TRIM control has two scales: just like in the mono channels,
there is a 0 to +40 dB scale that shows the preamplification of
the mic signal; the +20 to -20 dB scale shows the sensitivity for
the corresponding input level that is applied to the line input.
Both inputs can also be used with balanced or unbalanced
connectors.
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 Balance, mute switch 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 switch, MUTE LED, CLIP LED and 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 one point on each of the channel
strips and then routed to the main section all together.
