Auxiliary sends 1 & 2
Each of these controls sends a signal to an Aux bus. The signal is sourced pre-
fade which means that the level is independent of, and unaffected by the fader.
Auxes 1 & 2 are mono buses so the stereo pre-fade signals are summed to-
gether to provide the source for the send.
These sends are not affected by the Mute switch by default, so muting the
channel does not mute the Aux sends but they can be selected to be post-
mute where they will follow the mute status (internal jumper links).
The control varies the signal level to the bus from off (fully attenuated) to
+6dB, with unity gain at the arrow.
There are master level controls for all of the Auxiliary outputs situated in the
master section of the mixer.
Auxes 5 & 6
The source for Aux sends 5 & 6 is post-fader by default. They are muted by
the Mute status. Auxes 5 & 6 are primarily used for effects sends. However,
an internal jumper option can be altered to select them to be sourced pre-
fader, for example if more monitor sends are required.
Auxes 3 & 4
The source for Aux sends 3 & 4 is normally post-fader but can be selected
pre-fader by pressing the Pre switch.
Balance
The balance control adjusts how the stereo left and right channels are bal-
anced when routed to the stereo L-R mix bus or the pairs of group buses.
Unity gain is in the middle, the opposite signal is attenuated when set left or
right.
Bus Routing Switches
The L-R switch connects the post-fade left & right signals to the main
L-R mix bus via the balance control. For minimum noise from the mix
bus summing amplifier, leave the switches in their up positions if the
channel signal is not required on the bus.
The M switch routes the post-fade mono sum of left & right to a mono
mix bus which is independent of the balance control.
The 1-2 and 3-4 switches are for routing the post-balance signal to
pairs of audio sub-groups which have independent insert points, mas-
ter faders, outputs and sub routing to the main mix buses if required.
