TDM Mixer Plug-Ins
(TDM Systems Only)
Pro Tools TDM systems come with two dif-
ferent Mixer Plug-Ins: 16-bit Optimized
and 24-bit Optimized. In most cases, the
Mixer Plug-In that was automatically in-
stalled with your system is the best one for
all around use. The Mixer Plug-In that is in-
stalled depends on which Pro Tools system
you have:
Pro Tools 24 MIX and Pro Tools 24 The 24-
bit Optimized Mixer Plug-In is installed by
default. When you run your Pro Tools In-
staller, a copy of the 16-bit Optimized
Mixer is placed in the folder “Plug-Ins (Un-
used)”.
Pro Tools III The 16-bit Optimized Mixer is
installed by default. When you run your
Pro Tools Installer, a copy of the 24-bit Op-
timized Mixer is placed in the folder “Plug-
Ins (Unused)”.
The Pro Tools Session Setup window indi-
cates which of the two Mixer Plug-Ins is
currently installed.
