Helix DSP Pro MK3 10Ch DSP Processor

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.

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

TuneEQ
Performs automated EQ adjustments with a single measurement per channel using a measurement mic. Adjusts frequency, gain, and Q-factor.

RealCenter
Creates 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.

Augmented Bass Processing
Includes:

• Dynamic Bass Enhancement: Boosts deep bass and subsonic filtering dynamically

• SubXpander: Adds subharmonic content between 50–100 Hz for deeper bass
