4 − US-2000 Control panel settings 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." [Windows Control Panel] "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. [Mac OS X Control Panel] Control panel settings 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 12 TASCAM US-2000
