Important Latency Information
Mix 51 uses the host CPU to perform
the surround panning and mixing. It
introduces latency that is equivalent
to one buffer of audio based on the
Pro Tools H/W Buffer Size. The
latency in seconds can be calculated
with the formula (Buffer
Size)/(Sample Rate). For example, if
the Pro Tools H/W Buffer Size is set
to 512, the latency is 512/48000 =
10.6 ms at 48 kHz sample rate. To
set the H/W Buffer Size, open the
Playback Engine dialog and set the
control labeled H/W Buffer Size.
Important Pro Logic II Monitoring
Information
Mix 51 provides a stereo LtRt
downmix that is compatible with 5.1
Dolby Pro Logic II decoding systems.
It is very important that the Pro Logic
II decoder be set for Movie Mode.
