4 – US-122MKII Control panel settings
Overview
The Control Panel lets you make various
settings for the US-122MKII’s functionality.
On Windows XP and Windows Vista, the
US-122MKII & US-144MKII 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-122MKII & US-
144MKII 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.
The Control Panel is divided into the
following two sections.
Status section

Audio Performance
The US-122MKII 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-122MKII
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-122MKII
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.
