The most popular TASCAM 4-channel USB audio interface has been updated with better audio specs and a fresh new look for the US-144mkII. The US-144mkII starts with two great-quality XLR microphone preamps with phantom power for condenser microphones. There's also a pair of balanced line inputs and a guitar-level in for direct recording of electric guitar or bass. A pair of S/PDIF digital inputs and outputs is also included, for a total of four inputs and outputs at up to 96kHz/24-bit audio quality.

The US-144mkII connects to Mac or Windows computers using USB 2.0, and the unit is powered over the USB cable. Zero-latency monitoring is available for recording without the delay going to a computer and back. MIDI input and output jacks allow connection of synths and drum machines. Connect the US-144mkII to monitors through the line output or use headphones with the front-mounted stereo 1/4" jack. Separate controls for line and headphone out means you don't need to switch off monitors to work in headphones. The US-144mkII makes a perfect portable interface with metal components and solid construction built for the road.

The US-144mkII includes a copy of Cubase LE4 from Steinberg. This full-featured recording software captures up to 48 tracks of audio with another 64 MIDI tracks. You can edit your tracks to perfection using a variety of modes and tools. Automated mixing is included to create the perfect master. Cubase LE4 supports VST effect and instrument plug-ins, which an assortment included with the application.

For great-sounding tracks in your computer, trust TASCAM's 30 years of recording experience with the US-144mkII.

How do I authorize Cubase LE?

Cubase LE is authorized on the Steinberg website. Go to this page to get started.

Are TASCAM drivers compatible with Mavericks 10.9.5 and Yosemite?

According to Apple, OS X 10.9.5 includes heightened security measures that will also be part of OS X 10.10. These security measures will affect some TASCAM audio interfaces, so users are advised to be aware, and hold off on updating until further information is available

These products use Apple's built in CoreAudio driver. The Settings Panel installer is fully compliant with Apple's latest security measures.

US-2x2
US-4x4

The latest drivers are compliant, but testing is ongoing for these products:

US-322
US-366
US-1200
UH-7000

The OS X 10.9 public beta drivers can continue to be used for these interfaces:

US-122mkII
US-144mkII
US-200
US-600
US-1641
US-1800
US-2000

Cannot be used with the current driver (public or beta):

IF-FW/DMmkII: Development is on-going and a version that is compliant with the new security measures will be made available as soon as possible. Please keep your system at 10.9.4 or earlier if you wish to continue to use the IF-FW/DMmkII.
TASCAM Mixer Companion: Gatekeeper Security must be set to "allow all" for TMCompanion to be installed. It can be reverted to higher security settings after installation.
Other audio interface products not mentioned are no longer supported.

There is no MIDI input or output from my US-series interface when using it with Pro Tools 9 for Windows.

Pro Tools 9 for Windows must be run from the administrator's account for MIDI to function. Launch Pro Tools in 'run this program as an administrator' mode.

Pro Tools 9 for Windows will not launch with the US-series interface connected.

The latency setting must be the same in Pro Tools and in the US-series control panel. Change this in Pro Tools' Hardware Setup window, and in the US-series control panel.
