TASCAM US-1800

4 − US-1800 Control panel settings

Overview

The 

Control Panel

 lets you make various settings for the 

US-1800’s functionality.
On Windows OS, the 

US-1800 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-1800 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-1800 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-1800 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-1800 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

. When 

using digital input, set this to 

Automatic

.

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.

Digital Output Format

Set the digital output format to 

AES/EBU

 or 

S/PDIF

.

Digital Output Channels

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.

CAUTION

When using the digital input (

DIGITAL IN

), set 

Sample 

Clock Source

 to 

automatic

, and set the connected device 

as the clock master. Devices that cannot function as a 

clock master cannot be used with this unit. When the 

digital input (

DIGITAL IN

) and digital output (

DIGITAL OUT

are used at the same time, if the Control Panel 

Sample 

Clock Source

 is set to 

internal

, the DIGITAL IN signal cannot 

be received, so the DIGITAL OUT sound is returned to the 

DIGITAL IN as is, resulting in a feedback loop.
