Product overview
The next evolutionary stage of the DSP PRO
Familiar looks with the (r)evolution inside. The successor of the DSP PRO comes in the renowned, elegant HELIX design, but is equipped with the latest technology: Unrivalled High-Res sound quality thanks to twice as much processing power compared to its predecessor, ACO Platform for an extended feature set as well as VCP (Virtual Channel Processing) for easy configuration of highly complex sound systems. Additionally, there are the revised highlevel inputs with three-stage input sensitivity adjustment and extended voltage range up to max. 32 Volts as well as our extremely compact and solid Smart Control Port. One thing´s for sure: Due to featuring all these state-of-the-art technologies, the DSP PRO MK3 without a doubt belongs to the A-list of signal processors.
State-of-the-art Technology and TwinDSP power for the ultimate High-Res sound experience
The DSP PRO MK3 is equipped with two of the most powerful 64-Bit audio signal processors from Analog Devices. The incredible processing power of 2.4 billion MAC operations per second, combined with the high sampling rate of 96 kHz (resulting in an audio bandwidth of over 40 kHz) and AKM Velvet Sound A/D and D/A signal converters, ensure outstanding sound in High-Res quality.
ACO – Advanced 32 Bit CoProcessor Platform
The DSP PRO MK3 is now equipped with our proprietary 32 Bit ACO platform, which doesn’t just take over all control tasks ultra-fast, but also handles a bunch of audio functions: Now, fantastic sound effects such as Augmented Bass Processing or Real Center are implemented as well as a channel-separated Input EQ including Input Signal Analyzer (ISA) for easy analysis and compensation of input signals of OE radios, which already include a sound setup ex works.
All you need for optimal connectivity
With its wide range of in- and outputs (8 x high level, 8 x RCA, 1 x optical, 1 x coaxial, 1 x HEC slot & 10 x line output), the DSP PRO MK3 offers everything for an easy adaptation to existing factory radios or multi-channel OE sound systems. Additionally, the extended voltage range allows the combination with almost any imaginable analog signal source, even with high-power OE amplifiers.
