6.4.2 FireWire Sends and Returns

When using the StudioLive as an audio interface, it is important to
understand the terms "FireWire send" and "FireWire return. " Because
the audio interface in the StudioLive is completely integrated with the
other functions of the mixer, the FireWire I/O is designed to work as an
independent bus. You can route (send) signals from other buses to the
FireWire bus, and its output (return) signal is hard-coded to designated
mixer channels. Your StudioLive has 32 available sends and 26 returns.
FireWire sends 1 through 24 are hard-coded to be sent pre-fader from the 24 input
channels of the StudioLive. These sends can be pre- or post-Fat Channel EQ and
dynamics. To record the EQ and dynamics processing on any channel, simply
enable the Dig Out button. It will illuminate, indicating that the Fat Channel signal
path is being routed to the FireWire send. If this mode is not enabled, the signal
sent via FireWire will be post-trim and post-analog insert (if applicable). As
discussed in Section 4.5.1, the Dig Out button is not operable for the subgroups,
main outputs, aux bus, internal FX returns, and aux inputs. The subgroups, main
outputs, and aux inputs are also sent post-fader to their FireWire sends.
FireWire sends 25-32 are routed in 4 stereo pairs from the
Universal Control Device window. Any combination of four
of the following inputs and buses can be selected:
Main Mix Left / Right
Subgroup 1 & 2
Subgroup 3 & 4
Aux Send 1 & 2
Aux Send 3 & 4
Aux Send 5 & 6
Aux Send 7 & 8
Aux Send 9 & 10

Aux Send A & B (EFXA & EFXB Send)
Aux Return A (Aux Input A)
Aux Return B (Aux Input B)
FX Return A (EFXA Return)
FX Return B (EFXB Return)
2 Track Left/Right
Talkback Left/Right
Solo Left/Right
Note that either channel of the stereo pair can still be accessed on a mono
track in your host application; only the routing must be assigned as a stereo
pair. For instance, if you have a backing-vocal group routed to Subgroup
1 and a guitar group routed to Subgroup 2, you would create two mono
tracks in your recording application. The track whose input is assigned to
Subgroup 1 will record the backing-vocal group, and the track whose input
is assigned to Subgroup 2 will record your guitar group. If, however, you have
a stereo drum group assigned to Subgroups 3-4, you can create a stereo
track in your recording application and assign its input to Subgroups 3 and
4. For more information on subgroup mixing, please see Section 8.4.
The obvious exception to this principle is the Talkback Mic input. The Universal
Control Device window allows you to assign the talkback output to one of the
stereo FireWire sends. In this instance, the same signal will be printed on both
sides of the send. In your recording software, you can create a mono track and
assign it to either side of the stereo FireWire send to which it is routed. Both
FireWire sends receive the same mono signal from the talkback-mic preamp.
Please note that you have access to both the internal effects-send group as well
as the effects returns. If you record an internal effects send (Aux Sends A and B),
you will be recording the unprocessed ("dry") mix of the channels being sent
to that internal effects bus. To record the processed mix, choose the internal
effects returns (FX Return A or FX Return B). This is the direct output from the
internal effects, so it will be 100% wet. You may wish to record both the dry
and the wet mix so that you can blend them to taste within your session.
Section 7.2.5 discusses how to select the sources for these 4 stereo FireWire sends.
Each of the StudioLive's 24 inputs are hardcoded to receive their respective
FireWire returns. Outputs 1 through 24 in your recording application route these
playback streams to their respective channels on the StudioLive (that is, the
software's Output 1 always goes to StudioLive Channel 1 input and so on). Once
you route a track in your recording application to play through one of these
outputs, it will always be accessible on its channel by simply pressing the FireWire
input button.
To provide the most flexible mixing environment, the main mix output for any
application should be assigned to Outputs 25 and 26. These FireWire returns are
hard-coded to the FireWire input buttons in the 2 Track In and Monitor sections of
the StudioLive. In this way, you can monitor the main output from your recording
application without using two channels on your StudioLive, leaving the other 24
outputs available to be routed to the Fat Channel or for inserting a plug-in on a live
instrument (see the next section for more details).
