If the disc becomes scratched or dirty,
your computer may be unable to read it
and the software cannot be installed. If
the disc becomes unreadable, a fee will
be charged for its replacement.
WARNING
Never attempt to play the enclosed
CD-ROM in a conventional audio CD
player, as the resulting noise may dam-
age your speakers or your hearing.
Installing the drivers for Windows
The US-144’s drivers are provided on the
CD-ROM as an executable installer enti-
tled US-122L & US-144 driver x_yy.exe
(x_yy is the version number.) Installation
of the drivers requires that you run this
installer before plugging in your US-144
for the first time. If you do happen to plug
in your US-144 before running the install-
er, the Add New Hardware wizard will
appear. In this case, simply unplug the
US-144, cancel all the Add New Hardware
wizard windows, and run TASCAM’s driv-
er installer.
Installation procedure
Make sure that the US-144 is not con-1
nected to your computer.

ceed with the installation.

12 TASCAM US-144
3 – Installation
Installing the drivers for Mac OS X
The US-144’s drivers are provided on the
CD-ROM as a package file entitled
US-122L& US-144 driver x_yy.mpkg. (x_
yy is the version number.) Simply double-
click on this package file’s icon to launch it
and follow the directions that appear on
your screen.
Settings on your computer
Here are a few basic points to help you set
up your computer for best performance
with audio applications.
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.
This means that if you are running other
applications (especially graphics or
Internet tools) at the same time as your
audio application, the processing may
not happen fast enough.
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 and Windows Vista, this is
enabled by default.

IMPORTANT SAFETY PRECAUTIONS
Overview
4 – Control panel settings
The Control Panel lets you make vari ous
settings for the US-144’s functionality.
On Windows XP and Windows Vista, the
US-122L & US-144 Control Panel shortcut
can be found in the Windows Start menu in
the Windows control panel and also under
All Programs\TASCAM\US-122L &
US-144.
On Mac OS X, the US-122L & US-144
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.
The Control Panel is divided into the fol-
lowing two sections.
Status section
This shows the current status of the driver
and the connected hardware.
You cannot edit the settings from this sec-
tion.
Setting section
You can edit the various settings of the
driver.
Driver settings
Audio Performance
The US-144 driver temporarily stores input
and output audio samples 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 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.
You select the buffer size that works best
for your system.
On the Windows version of the US-144
Control Panel, the Audio Performance set-
ting permits you 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 set-
ting is the maximum buffer size.
On Mac OS X, the buffer size is deter-
mined by each audio application.
Consequently, there is no Audio
Performance setting on the Mac OS X ver-
sion of the US-144 Control Panel. Some
applications select the buffer size automati-
cally while others permit the user to select
the buffer size. Please consult your audio
application’s documentation for details.

Sample Clock Source
You can set the clock source to Automatic
or Internal.
Automatic (default): If a signal is being
input to the DIGITAL IN jack, its clock will
be used. If no signal is being input to the
DIGITAL IN jack, the US-144’s internal
clock will be used.
Internal: The US-144’s internal clock will
always be used.
This lets you choose either AES/EBU or
S/PDIF as the digital output format.
Many professional devices use an XLR
connector for AES/EBU. Special adapters
may be purchased to convert between a
digital audio RCA connector and digital
audio XLR connector.
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.

5 – Connections
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
Computer
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.
NOTE
The US-144 has two input channels (L,
R), with a MIC IN jack (XLR) , LINE IN
and LINE/GUITAR 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 cor-
rectly input to the US-144.
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.
