Description HELIX DSP PRO MK3 The next evolutionary stage of the DSP PRO – familiar looks with revolutionary improvements inside. The successor of the DSP PRO comes in the renowned, elegant HELIX design but is equipped with the latest technology: unrivaled High-Res sound quality thanks to twice the processing power compared to its predecessor, ACO platform for an extended feature set, and VCP (Virtual Channel Processing) for easy configuration of highly complex sound systems. Additionally, there are revised high-level inputs with three-stage input sensitivity adjustment and an extended voltage range up to 32 Volts, as well as an extremely compact and solid Smart Control Port. 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. With a processing power of 2.4 billion MAC operations per second, a high sampling rate of 96 kHz (resulting in an audio bandwidth over 40 kHz), and AKM Velvet Sound A/D and D/A converters, it delivers outstanding High-Res sound quality. ACO – Advanced 32-bit CoProcessor Platform The proprietary ACO platform takes over all control tasks quickly and handles advanced audio functions. Features include: Augmented Bass Processing Real Center Channel-separated Input EQ Input Signal Analyzer (ISA) for analysis and compensation of input signals from OE radios with factory sound setups Optimal Connectivity With a wide range of inputs and outputs: Inputs: 8 x High-Level, 8 x RCA, 1 x Optical, 1 x Coaxial, 1 x HEC slot Outputs: 10 x Line-Out (RCA)The DSP PRO MK3 easily adapts to factory radios or multi-channel OE systems. The extended voltage range supports compatibility with nearly any analog signal source, even high-power OE amps. DSP PC-Tool 5 Featuring TuneEQ Configure the DSP PRO MK3 using the intuitive DSP PC-Tool 5. Key features: Extensive sound processing options TuneEQ for automated frequency response correction Time-saving optimization Exceptional precision even in challenging acoustic environments Key Features TwinDSP Power: Two fixed-point 64-bit Audio DSPs with 2.4 billion MAC operations/sec High-End Signal Converters: 32-bit A/D and D/A converters by AKM ACO Platform: For extended control and audio feature set ISA & InputEQ: For signal analysis and compensation TuneEQ: Automated output EQ adjustment SFX: Sound Effects – Augmented Bass Processing, RealCenter VCP: Flexible sound system configuration HEC Slot: Expandability via Bluetooth HD Audio, USB streaming, etc. High-Level Inputs: Smart 8-channel with ADEP.3 circuit Start-Stop Capability: Operates down to 6V supply Ground Lift Switch: Eliminates ground loops Smart Control Port (SCP): Compact, future-proof accessory connection Time Alignment: Up to 20 ms delay per channel, reverse time alignment Flexible Signal Routing: Separate matrices for Line, SPDIF, HEC/AUX Special Features TwinDSP Power Dual 64-bit DSPs deliver outstanding performance, enabling twelve separate processing channels and a 96 kHz sampling rate. ACO CoProcessor Offers: Lightning-fast control Channel-separated Input EQ Sound effects (Augmented Bass, RealCenter) Revolutionary TuneEQ Integrated bootloader for future firmware updates ADEP.3 High-Level Input Prevents diagnostic errors in factory systems without stressing outputs at high volume. Start-Stop Capability Stable performance even during engine cranking with voltage drops down to 6V. Power Save Mode Reduces power draw when no signal is detected for 60 seconds. Wake-up is instant upon audio input. Can be disabled or adjusted via software. Automatic Digital Signal Detection Switches inputs automatically when a digital signal is detected (optical/coaxial). Manual switching available via remote. DSP Highlights TuneEQPerforms automated EQ adjustments with a single measurement per channel using a measurement mic. Adjusts frequency, gain, and Q-factor. RealCenterCreates a dynamic center signal by emphasizing shared information in the left and right channels for a natural sound stage. Unlike traditional methods, it reduces center signal dynamically rather than with a fixed attenuation.
