Auxiliary Sends
This section comprises one stereo and six mono sends. Either
audio path, controlled by the Large or Small Fader within each
module, may be routed to any of the send busses, in any pre or
post-fader permutation.
Each send has a level control with a built-in push-on/push-off
switch so that levels may be preset and easily switched in and
out. These switches are automated and the On/Off switching
is electronically latched. A yellow LED indicates that the send
is ON. The stereo send also has a pan control.
The source select buttons for each send are:
SF (SMALL FADER) – When pushed down the send is derived
from the Small Fader signal path and when up, the send is
from the Large Fader signal path.
PRE – At the bottom of this section, four switches allow the
aux sends to be switched in pairs to be pre-fader. When pushed
down, the sends are derived pre-fader and when up, post-
fader.
EFX – Each aux send control can be disconnected from its own
bus and re-routed to any one of the four A, B, C, D stereo
busses, the multitrack busses or the channel direct output via
one of two ‘EFX’ busses which are internal to the module.
Pressing the EFX button on even numbered aux sends (2, 4 and
6) routes that send onto the EFX EVEN bus. A green LED lights
to show that the switch is active. Pressing the EFX button on odd numbered aux sends
(1, 3 and 5) routes that send onto the EFX ODD bus. A red LED lights to show that the
switch is active. Pressing EFX on the stereo send routes Stereo Cue left to EFX ODD
and Stereo Cue right to EFX EVEN. Only one aux send control can be assigned to an
EFX bus at any one time, ie. a maximum of one odd and one even numbered aux, or
the stereo aux. Lower numbered sends take priority over higher numbered ones. Cue
Stereo takes priority over all mono auxes.
This feature allows a large number of independent headphone or effects send mixes to
be generated, without using the Small Fader.
All the Aux send bus outputs appear on the jack field, and can be used as feeds to
effects units. See Section 5 for details of the Foldback and Studio Loudspeaker
systems.
