ATLAS

Ultra-high fidelity 192kHz 8-channel USB interface

Availability: In Stock

Condition: New

The Prism Sound Atlas is a USB multi-channel interface aimed at multi-tracking applications featuring a similar feature set to Titan (including the MDIO expansion slot for optional Pro Tools HDX, AES and potentially other digital cards), Atlas will be perfect in the project and multi-track studio for recording as well as for mixing, stereo and stem mastering. The Lyra, Titan and Atlas models feature a 20dB pad on each mic channel to accommodate high sound pressure level (SPL) applications such as drums or close micd guitars or brass.

Our low noise, low distortion, extremely neutral mic pre design has gained a cult popularity amongst existing Prism Sound users and we are pleased to be able to offer a single box 8 channel solution for producers, artists and engineers demanding high-quality front-end with the added benefits of Prism Sound A/D and D/A conversion.
