DSP-4 D
DSP-4 D
Description
The DSP-4D standalone digital signal processor (DSP) is a powerful and smart DSP processor primarily for use in combination with ASCENDO’s non-DSP amps for use in our subwoofer systems.
This DSP system isn't just powerful—it's smart. ASCENDO designed a system control interface that can manage multiple machines from a single user interface, handling hundreds, if not thousands, of DSP channels. This system is fully compatible with Dante and AES67, ensuring seamless interoperability with various AoIP systems like Ravenna, Milan, AVB, and Dante.
This standalone DSP is a great upgrade for any home theater immersive audio system. It’s more than just a component—the DSP-4D is the heartbeat of a high-performance home theater system, offering clarity, power, and precision.
