Omnia VOLT is the latest triumph from the people who brought you the multiple-award-winning Omnia.11, the acclaimed Omnia.9, the power-packed Omnia 7, and the 13,000+ Omnia ONEs currently in service. But this is not just another audio processor. With VOLT, we have rewritten the rules for broadcast DSP, fine-tuning our algorithms and creating the world’s best-sounding, most powerful, incredibly versatile 1RU audio processor. VOLT gives you more sonic performance and processing power in one rack unit than others give you in three.
