Settings on your computer  
Here are a few basic points to help you set  
up your computer for best performance  
with audio applications.  
Internet tools) at the same time as your  
audio application, the processing may  
not happen fast enough.  
• Do not run other applications. You will  
probably use your computer for applica-  
tions other than audio, but we recom-  
mend that you avoid running other appli-  
cations at the same time you are running  
audio programs. Processing digital audio  
places a considerable load on your com-  
puter.  
• Certain devices such as network cards or  
WinModems can cause conflicts with  
USB processing. If you experience such  
a conflict, you can use the Device  
Manager to temporarily disable the  
offending device.  
• If your computer has an IDE hard disk,  
enabling Direct Memory Addressing  
(DMA) will improve performance. In  
Windows XP, this is enabled by default.  
This means that if you are running other  
applications (especially graphics or

4 – Control panel settings  
Overview  
The Control Panel lets you make various  
settings for the US-144’s functionality.  
Setting section  
Here you can edit the various settings of  
the driver.  
The Control Panel is divided into the fol-  
lowing two sections.

Audio Performance  
The US-144 driver temporarily stores input  
and output audio samples in buffers.  
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.  
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 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.  
A smaller buffer size will reduce the delay  
when monitoring the input signal, but will  
require your computer to perform the pro-

This lets you choose either AES/EBU or  
S/PDIF as the digital output format.  
USB 1.1 Mode Input Selection  
This item is shown only if the US-144 is  
connected to a USB 1.1 port on the host  
computer or to a USB 1.1 hub. In this case,  
the US-144 functions as a 2-in / 2-out  
audio device, rather than the usual 4-in / 4-  
out. You can choose either Analog or  
Digital as the input source.

USB connections  
Using the included cable, connect the  
US-144 to your computer as shown in the  
illustration.  
NOTE  
Some USB devices access the USB bus  
frequently. To avoid dropouts and clicks  
in the audio signal, we strongly recom-  
mend that you do not connect other  
USB devices to the USB bus used by the  
US-144.  
USB keyboards and mice are exceptions  
to this, and will probably not cause  
problems.

USB  
Audio connections  
Connect the output signal of your mic, gui-  
tar, keyboard, or other audio device to the  
US-144, where it will be converted into  
digital audio and sent via USB to your  
computer. Connect the output of the  
US-144 to your speakers (via an amp) or  
headphones, so you will be able to monitor  
the audio signals coming into the US-144  
or being produced by your computer.  
Mic  
Connect your mics to the MIC IN (L, R)  
jacks (XLR). If you are using a condenser  
mic that requires phantom power, turn on  
the phantom power.  
NOTE  
If you're using a  
condenser mic  
The US-144 has two input channels (L,  
R), with a MIC IN jack (XLR) and LINE IN  
jack (1/4” phone jack) provided for each  
channel. Do not connect signals to both  
of these analog input jacks at the same  
time. If both are connected, the signal  
will not be correctly input to the  
US-144.

Project menu, choose Project Settings, and  
set the sample rate to 44,100 Hz.

correct.  
Q. The sound is distorted.  
A. Make sure that the signal is not over-
