Digidesign 2 Manual De Usuario

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 21 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 21 
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. 

2  

In Pro Tools LE, choose Setups > Hardware 

Setup.

3  

Make sure the correct digital input option is 

selected for your setup. When you select RCA 
S/PDIF, the Optical ports are available for stan-
dard ADAT Optical (or “Lightpipe”) input. 
When you select Optical S/PDIF, the RCA digital 
input connector is inactive.
