Prism Sound Atlas Multichannel Audio Interface Affordable Sale Online

Prism Sound Atlas Multichannel Audio Interface

Atlas and Titan are world class multi-track interfaces offering flexible expansion and unsurpassable sonic clarity. Using the latest generation of Prism Sounds trusted conversion, Atlas provides more preamps than Titan making It’suitable for a wider range of recording scenarios.

UNSURPASSED CLOCKING AND JITTER REJECTION
Prism Sounds history in developing test and measurement equipment for the audio industry has allowed our engineers to get a much deeper understanding of digital clocking and its associated issues.

DIGITAL MIXER WITH FLEXIBLE MONITORING
Atlas has a powerful built-in digital mixer that can be configured to provide a multitude of ultra low latency feeds, Including foldback to performers, stereo and surround outputs.

MIC PREAMPS
The Atlas boasts 8 ultra-clean, low-noise microphone preamps that perfectly compliment its transparent A/D conversion (with software controllable phantom power, -20dB pad and Overkiller limiter switches on each channel.)

FUTURE PROOF CONNECTIVITY
With a standard USB connection Atlas can connect to the widest range of computers today and for the foreseeable future. Add to this the option of ProTools HDX and Dante modules for the most flexible and professional solution.
