The Perfect Combo

Building on the unique decoding and rendering capabilities of the Altitude32, the Altitude48ext pushes the limit further with up to 48 individual decoded outputs and a total of 64 processing outputs.

The Altitude32 can be unlocked to deliver up to 48 individual outputs. This is made possible by enabling its 32 analog and 16 digital outputs simultaneously.

Full Home Atmos Experience

It allows – for the first time – users to experience the full Home Atmos experience with its 24.1.10 layout, while still allowing more possibilities in term of bass management or multi-amping and remapping.

However, that solution requires an AES multi-channel High-end DAC that could compete with Altitude’s own renowned DAC: Trinnov’s solution to that problem is Trinnov Altitude48ext.
