Routing a Plug-In as a Bus Processor
Plug-Ins can be used on busses for send-and-return processing
with effects such as reverb and delay. A plug-in is configured for
bus processing by assigning an Aux, Group, Matrix, Main, Mon-
itor output, or an Input Channel Direct Out as the plug-in input
source, then assigning the output of the plug-in to an Input Chan-
nel or FX Return, or to a hardware output, as follows:
• Return bus-fed plug-ins to an Input Channel or FX Return
to establish an effects send-and-return path.
• Route bus-fed plug-ins to a hardware output for specialized
processing needs (such as feeding an external crossover).
You assign plug-ins for bus processing from the Plug-Ins screen.
To use a plug-in as a bus processor:
1 Go to the Plug-Ins page.
2 Make sure the plug-in is installed and assigned to a rack slot.
3 Click the Plug-In Input selector at the top of the corresponding
rack slot, and choose an available bus from the Input
sub-menus.
4 Click the Plug-In Output selector and choose an Input Chan-
nel, FX Return or hardware output.
When a bus-fed plug-in has both its input source and output as-
signed, it appears similar to the following in the rack:
Routing Channel Direct Outs to Plug-Ins
You can route the Input channel Direct Outs to plug-ins. This lets
you directly feed plug-ins from individual channels to preserve
Aux busses for other uses, with control over send level using the
channel Direct Out level control.
When a channel Direct Out is routed to a plug-in, it follows the
pickoff setting for that specific Direct Out (as set in the Patch-
bay), and is applied in addition to any other assignment made for
that Direct Out. This makes it possible to use a channel’s Direct
Out to route that channel to both a Pro Tools recording option and
to a plug-in.
Assigning plug-in Input source to a Group bus
When routing a plug-in with a stereo output to an Input
Channel, make sure the Input Channel is a stereo channel.
See “Make Selected Mono Strips Stereo/Make Selected Ste-
reo Strip Mono” on page 48.

Plug-Ins page
If you do use a Direct Out to feed both a hardware output
such as a Pro Tools recording option as well as a plug-in, be
aware that any adjustments to that Direct Out affect both the
output signal and the signal fed to the plug-in.
