TASCAM US-2000
Overview
The “Control Panel” lets you make various settings for the
US-2000’s functionality.
On Windows XP and Windows Vista, the “US-2000 Control
Panel” shortcut can be found in the Windows “Start menu
> Control Panel” or the “Start menu > All Programs >
TASCAM.”
On Mac OS X, the “US-2000 Control Panel” is located
in the Applications folder. Other useful audio and MIDI
settings for Mac OS X can be found in “Applications/
Utilities/Audio MIDI Setup.”

Audio Performance
The US-2000 driver temporarily stores input and output
audio sample in buffers. The size of these buffers can be
adjusted. A smaller buffer size will reduce the delay when
monitoring the audio signal, but will require your computer
to perform the processing faster. If the processing does
not occur in time (e.g., if other system operations are
occurring), you may hear clicks, pops, or dropouts in the
audio signal. A larger buffer size provides more safety
against such problems caused by other system activities,
but will produce greater delay when monitoring the audio
signal. You should select the buffer size that works best for
your system.
On the Windows version of the US-2000 Control Panel,
the “Audio Performance” setting permits you to adjust the
buffer size that will be used by all audio applications. The
“lowest latency” setting is the minimum buffer size, and the
“highest latency” setting is the maximum buffer size.
On Mac OS X, the buffer size is determined by each audio
application. Consequently, there is no “Audio Performance”
setting on the Mac OS X version of the US-2000 Control
Panel. Some applications select the buffer size automatically
while others permit the user to select the buffer size. Please
consult your audio application’s documentation for details.
Sample Clock Source
The clock source can be set to “Automatic” or “Internal.”
Automatic (default): If a clock signal is input through the
•
DIGITAL IN
jack, it is used. If no signal is input through
the
DIGITAL IN
jack, this unit’s internal clock is used.
Internal: This unit’s internal clock is always used.
•
When using digital input, set this to “Automatic.”
•
Digital Output Format
Set the digital output format to “AES/EBU” or “S/PDIF.”
Digital Output Chanels
The
DIGITAL OUT
jack outputs either digital signals of
LINE
OUTPUTS 1/2
or
3/4
. You select which pair of signals to
output using this item.
