ARCAM AVA25 – Frequently Asked Questions

What does 16-channel processing mean?

Processing capacity is not the same as having sixteen speaker amplifiers inside the product. An installation using more than its nine internally powered channels may need suitable external power amplification and careful channel assignment.

Will it work with Dolby Atmos and Auro-3D?

ARCAM's dealer information lists Dolby Atmos, DTS:X, IMAX Enhanced and AURO-3D. The source signal and speaker layout must also support the chosen format.
