12 TASCAM US-2000OverviewThe “Control Panel” lets you make various settings for theUS-2000’s functionality.On Windows XP and Windows Vista, the “US-2000 ControlPanel” 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 locatedin the Applications folder. Other useful audio and MIDIsettings for Mac OS X can be found in “Applications/Utilities/Audio MIDI Setup.”[Windows Control Panel][Mac OS X Control Panel]Control panel settingsAudio PerformanceThe US-2000 driver temporarily stores input and outputaudio sample in buffers. The size of these buffers can beadjusted. A smaller buffer size will reduce the delay whenmonitoring the audio signal, but will require your computerto perform the processing faster. If the processing doesnot occur in time (e.g., if other system operations areoccurring), you may hear clicks, pops, or dropouts in theaudio signal. A larger buffer size provides more safetyagainst such problems caused by other system activities,but will produce greater delay when monitoring the audiosignal. You should select the buffer size that works best foryour system.On the Windows version of the US-2000 Control Panel,the “Audio Performance” setting permits you to adjust thebuffer 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 audioapplication. Consequently, there is no “Audio Performance”setting on the Mac OS X version of the US-2000 ControlPanel. Some applications select the buffer size automaticallywhile others permit the user to select the buffer size. Pleaseconsult your audio application’s documentation for details.Sample Clock SourceThe 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 throughthe 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 FormatSet the digital output format to “AES/EBU” or “S/PDIF.”Digital Output ChanelsThe DIGITAL OUT jack outputs either digital signals of LINEOUTPUTS 1/2 or 3/4. You select which pair of signals tooutput using this item.4 − US-2000 Control panel settings
