2.4.2 Additional stereo line inputs

There are two additional stereo line inputs (aux return
operates in mono if only the left channel socket has a jack connected.
Level can be adjusted by the faders
aux return 2 (FX return) is usually reserved for the internal effects processor. But you can also use the
FX return input connectors
as an additional stereo line input.
The aux returns have been cleverly designed to be multifunctional. They may be used for returning the outputs
of effects units. You can use them as tape returns from a multitrack recorder. They may also be used as extra
instrument inputs, especially if your MIDI keyboard or rack supplies a pre-mixed stereo signal.
Certain stereo effects produce a perceived imbalance between the left and right channel levels. To correct for
this you will have to bring your stereo effect back on a stereo channel, which has a balance control.

2.4.4 Channel mode

The CHANNEL MODE switch
channel solo buttons.
Solo
Solo is the preferred method for auditioning an isolated signal, or group of signals. Whenever a solo button is
pressed, all unselected channels are muted in the monitors. Stereo panning is maintained. The solo bus is
derived from the output of the channel pans, aux sends and stereo line inputs. It is always post-fader.
PFL
Pressing
once disengages the stereo solo bus, and replaces it with a separate mono PFL (Pre-Fader-
Listen) bus. Now any channel which is solo-ed, isn't. It is PFL-ed instead. PFL should always be used for gain
setting (see also chapter 3 "PRACTICE").

2.4.5 2-track input and output

Input
A 2-track input, on RCA connectors

The 2-track input is primarily for auditioning mix playback from tape. Switch
routes this signal to the monitors and/or phones.
However, it can also be routed to the main mix via button
for tape playback, MIDI instruments etc. Here switch
2-track signal twice over!
With
depressed you have another stereo line input available to the mix, useful e.g. for adding the output of
a second EURORACK or a BEHRINGER ULTRALINK PRO MX882 to your mix (see chapter 4.4 "Expanding").
Output
The main mix output is delivered by XLR connectors
