Overview
The US-144 is a USB-based audio inter-
face designed for use with Digital Audio
Workstation (DAW) software. It provides a
four-input, four-output 24-bit 96 kHz audio
interface and a 16-channel MIDI interface.
Because the US-144 is USB-based, it is the
ideal companion to any desktop- or laptop-
based digital recording setup. And since
the US-144 operates using only USB
power, you can use it with a laptop com-
puter to create a very compact and portable
digital audio workstation system.
The US-144 is also an ideal way to capture
analog sources such as records or cassette
tapes into your computer and preserve
them as audio CDs.

anced/unbalanced) are provided. One of
