Versaural Evo

Versaural Evo

The gamechanger in Automotive Audio:

– 64 GFLOPS DSP Processing Power
– 30 Class-D Amplifier channels with up to 500W/Channel
– Digital Multiphase Multirail Boost supply
– 1GBit and 100MBit/sec OABR Ethernet AVB
– 2x Automotive Audio Bus (A2B) Controllers
– 8x Analogue Audio Inputs
– FD-CAN Bus interface
– Full Automotive Spec
– Dual and Quad-Core Cortex-A35 variants running Automotive Linux
– Dedicated M7 Core for AutoSAR OS

To reach this outstanding performance the GPU is used as accelerator for audio filtering, e.g. processing long FIR filter chains for room equalization/simulation which coeffiecients could be generated using Dirac Unison.


Probably the most versatile, most powerful and best sounding amplifier in the Automotive Audio market.
