Getting Started with Digi 00212
DAE Playback Buffer Size
The DAE Playback Buffer Size determines the
amount of memory DAE uses to manage disk
buffers, which affects system performance.
Though the default DAE Playback Buffer size
provides optimum performance in most cases,
you may want to adjust it to modify your sys-
tem’s performance.
◆ A larger buffer size can sometimes allow for a
higher density of edits in a session. However,
choosing a larger buffer size can cause a time lag
to occur before playback or recording begins. It
can also cause a time lag to occur when you are
editing during playback.
◆ A smaller buffer size can sometimes improve
playback and recording initiation speed. How-
ever, a smaller buffer size can make it difficult
for slower hard drives to play or record tracks re-
liably.
Configuring Hardware Setup
The Pro Tools Hardware Setup dialog allows you
to select the default sample rate and the clock
source for the system, and configure the digital
inputs on the Digi 002.
To configure Hardware Setup options:
1 Choose Setups > Hardware Setup.
2 Select the clock source from the Clock Source
pop-up menu. If you are recording directly into
Pro Tools, you will usually use Internal. If you
are transferring material from an external digital
device, select the corresponding clock source.
(See “Using a Digital Source” on page 12 for de-
tails.)
3 Select the default sample rate (this setting is
available only when a session is not open) from
the Sample Rate pop-up menu. This setting will
appear as the default sample rate when you cre-
ate a new session.
4 Choose a digital input option, depending on
the type of input devices connected to your sys-
tem. (See “Using a Digital Source” on page 12
for details.)
5 If you are outputting material to a Tascam dig-
ital device such as a DA-30, select the Tascam
option under “S/PDIF Output Cat. Code.”
Using a Digital Source
If you are recording from an Optical or S/PDIF
device, you will need to choose synchronization
settings. In most cases, you will synchronize
Pro Tools to the external device.
To configure Pro Tools LE for a digital source:
1 Connect an ADAT or Optical S/PDIF format
device to the Optical In connector, or an RCA
S/PDIF format device to the RCA S/PDIF In con-
nector on the back of the Digi 002.
Hardware Setup dialog for Digi 002
You can change the sample rate when cre-
ating a new Pro Tools session by selecting a
different sample rate in the New Session di-
alog. (See
“Starting a Session” on page 54.)
You can only use one pair of S/PDIF inputs
(either RCA or Optical) at a time.
