25. FireWire / USB Pre/Post Switch
This switch is used to change the signal of the
corresponding channel that is sent to the Computer via
the FireWire or USB interface between that of a pre-EQ,
pre-fader, pre-low cut and that of a post-EQ, post-fader,
post-low cut. In the upper-most position, the channel will
be pre, and in the lower position post.
26. AUX Controls
These controls alter the signal level that is being sent to
the auxiliary 1 and 2 mixes. The signals of these mixes are
suitable for connecting stage monitors, allowing artists to
listen to the music that is being played. Also included is a
Pre/Post button, which alternates the feed to the AUX 2
mix between a post and pre-fader feed.

27. EFX Control
This control alters the signal level that is sent to the EFX
send (AUX 3) output and the built-in digital effect processor.
The EFX send signal can be used in conjunction with
external signal processors (this signal of which can be
returned to mixer via the AUX return input), or simply as
an additional auxiliary output.
28. Pan / Balance Controls
This alternates the degree or level of audio that the left
and right side of the main mix should receive. On mono
channels, the PAN control will adjust the level that the
left and right should receive (pan), where as on a stereo
channel, adjusting the BAL control will attenuate the left
or right audio signals accordingly (balance).
29. On Button and Indicator
This turns the channel on, allowing the user to use the
feed from the channel's inputs to supply the MAIN L/R,
GROUP 1/2, AUX and EFX buses. The corresponding
indicator will be illuminated when turned on.
30. 1-2 and L-R Buttons
These handy buttons allow you to decide the audio path
of the corresponding channel. Pushing the "1/2" button
allows the signal to be sent to the Group 1/2 mix, where
the "L-R" allows it to be sent to the Main L/R mix.
31. Peak Indicator
This LED indicator will illuminate when the channel hits
high peaks, 6 dB before overload occurs. It is best to
adjust the channel level control so as to allow the PEAK
indicator to light up on regular intervals only. This will
ensure a greater dynamic range of audio. This indicator
also doubles as a Solo indicator, when the Solo button is
engaged.
32. Solo Button
The Solo button is pushed to allow the signal of a
corresponding channel to be sent to the Control Room
/ Phones control (pre or post fader, depending on the
properties selected by the pre / post button, located by
the Control Room / Phones control), for use with either
headphones or studio monitors. This also allows easier
setting of the input gain and tracking of audio by sound
engineers. The Peak indicator above the Solo button also
doubles as a Peak Indicator, illuminating when the signal
reaches high peaks.
33. Channel Level Control (Fader)
This control will alter the signal level that is sent from the
corresponding channel to the appropriate mixing buses
(whether they are the MAIN L/R or AUX).
