Tascam US-144 User Manual

The Control Panel lets you make various 
settings for the US-144’s functionality.
The Control Panel is divided into the fol-
lowing two sections.

This shows the current status of the driver 
and the connected hardware.
You cannot edit the settings from this sec-
tion.

Here you can edit the various settings of 
the driver.

The US-144 driver temporarily stores input 
and output audio samples in buffers.
The Audio Performance setting lets you 
adjust the buffer size. The Lowest Latency 
setting is the minimum buffer size, and the 
Highest Latency setting is the maximum 
buffer size.
A smaller buffer size will reduce the delay 
when monitoring the input signal, but will 
require your computer to perform the pro-

cessing faster. If the processing does not 
occur in time (e.g., if other system opera-
tions 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 sys-
tem activities, but will produce greater 
delay when monitoring the audio signal. 
The US-144 lets you select the buffer size 
that works best for your system.

You can set the clock source to Automatic 
or Internal.

 If a signal is being 

input to the 

 jack, its clock will 

be used. If no signal is being input to the 

 jack, the US-144’s internal 

clock will be used.

 The US-144’s internal clock will 

always be used.
