Audiomedia III Systems
Pro Tools can receive external clock from
the S/PDIF input on the Audiomedia III
card.
To select an external clock source for an
Audiomedia III system:
1 Choose Setups > Hardware.
2 Set the Sync Mode to match the type of
input.
Creating a Submix
You can use an Auxiliary Input to create a
submix by sending the output of several
tracks to the Auxiliary Input instead of to
the main mix outputs of your session.
You can then apply real-time Plug-Ins to
the submix or send the submix to an exter-
nal processor by using Inserts or Sends on
the Auxiliary Input track.
The following example illustrates how to
create a stereo submix group.
To create a submix:
1 Choose File > New Track and choose Aux
Input (stereo) from the pop-up menu.
2 Set the output of the tracks you want to
include in the submix to a bus pair and set
the panning of each track.
3 Set the input of the Auxiliary Input track
to the same bus pair.
4 Set the output of the Auxiliary Input
track to your main stereo mix outputs (typ-
ically, outputs 1–2).
5 Set the Auxiliary Input level.
The Auxiliary Input track controls the out-
put levels of all tracks routed to it. You can
apply mix automation to the Volume, Pan,
Mute, and Send Level, Send Pan, and Send
Mute controls of the Auxiliary Input.
You can also bounce a submix to disk to
free up the voices for use by other tracks.
See “Recording a Submix to Disk” on
page 282.
Soloing Tracks in a Submix
When you want to solo any tracks in a sub-
mix, you can solo-safe the Auxiliary Input
track. This allows you to solo tracks that are
bussed to the Auxiliary Input without hav-
ing to solo the Auxiliary Input as well.
To solo-safe an Auxiliary Input:
■ Command-click (Macintosh) or Control-
click (Windows) the Solo button on the
Auxiliary Input track.
Applying an Insert to a Submix
You can use a real-time Plug-In or a hard-
ware I/O insert as a shared resource for all
tracks included in a submix. This allows
you to control an effect such as EQ on mul-
tiple tracks (such as stereo pairs) with a sin-
gle set of controls. This also makes the most
efficient use of your system’s processing
power, as it saves you from having to apply
the same Plug-In to each track separately.
