Helix M Six DSP (M – Series)

HELIX M SIX DSP

Unleash Superior Sound – The New HELIX M SIX DSP

The HELIX M SIX DSP isn’t just another six-channel car audio amplifier – it’s a cutting-edge powerhouse that combines compact design with the advanced performance of a 10-channel DSP processor. Despite its sleek form, it delivers an impressive 100 Watts RMS per channel at both 4 Ohms and 2 Ohms. With its unmatched feature set and exceptional value, this amplifier promises a truly high-end audio experience at a competitive price.

Signature HELIX Sound Quality

HELIX products are engineered for pure sound – and the M SIX DSP is no exception. Built with high-precision A/D and D/A converters and powered by an ultra-efficient Analog Devices DSP chip, the audio signal path is designed for flawless fidelity. The DSP board, crafted in Germany, ensures premium performance. With four preamp outputs delivering up to 6 Volts, it easily drives additional amplifiers with high signal integrity.

Ultimate Flexibility in Amplifier Configuration

The internal amplifier is designed for maximum versatility. Operate it in 6-channel mode or bridge it for 5-, 4-, or even 3-channel configurations. Combined with four preamp outputs, it can scale up to a 10-channel system seamlessly. Integrate with other M Series amps like the M ONE X, M ONE, M FOUR, or another M SIX for powerful, space-saving multi-channel audio setups that are both cost-effective and high-performing.

Advanced Signal Routing with Virtual Channel Processing (VCP)

Managing multiple DSP channels has never been easier. Thanks to Audiotec Fischer’s innovative Virtual Channel Processing, the M SIX DSP simplifies signal routing for complex OEM audio systems. Whether you’re blending or splitting inputs, configuring multi-way setups, or assigning FX sound features like RealCenter and Augmented Bass Processing, the DSP PC-Tool software ensures a user-friendly and efficient experience.

Speed and Precision with ACO CoProcessor

Powered by a high-speed 32-bit ACO platform, the M SIX DSP excels in responsiveness. This advanced CoProcessor handles all control functions, boosts communication speed with the DSP PC-Tool, and enables lightning-fast switching between up to 10 sound presets. It also powers exclusive HELIX audio features, including Input Signal Analyzer (ISA), Input EQ, and FX sound effects, for precise audio tuning.

Compact, Efficient, and OEM-Ready

Despite its powerful capabilities, the M SIX DSP retains the iconic, compact HELIX design. Built on Class D amplifier technology, it remains cool under pressure. Features like start-stop support, the ADEP.3 high-level input diagnostic systems, and energy-efficient Power Save Mode make it the perfect fit for modern OEM integrations.

Standout Technologies

ACO – Advanced Co-Processor

The HELIX M SIX DSP’s ACO (Advanced CoProcessor) platform streamlines monitoring and communication, providing ultra-fast setup switching and reliable updates via DSP PC-Tool. With 10 memory slots for custom sound setups and future-ready software upgrade support, it’s built to grow with your system.

Smart High-Level Input with ADEP.3

Avoid diagnostic issues with modern OEM head units. The integrated ADEP.3 (Advanced Diagnostics Error Protection) prevents error messages and function loss (like fading), ensuring seamless integration without stressing the head unit’s outputs.

Power Save Mode for Efficient Operation

When no audio signal is detected for over 60 seconds, Power Save Mode reduces power usage by shutting off connected amplifiers. It reactivates instantly when audio returns. Customize the delay or disable the mode entirely via DSP PC-Tool.

Start-Stop Ready

Thanks to its robust switched power supply, the M SIX DSP maintains stable operation even during voltage dips as low as 6V – ideal for vehicles with start-stop systems.

Exclusive DSP Features

TuneEQ – Automated Frequency Response Optimization

TuneEQ simplifies tuning by automatically adjusting EQ settings to match a reference curve using just one measurement per channel. Compatible with HELIX’s MTK1 microphone, this tool saves time and delivers professional-grade audio optimization.

RealCenter – Dynamic Center Channel Algorithm

HELIX’s RealCenter algorithm extracts shared stereo information to generate a precise, dynamic center channel. Unlike traditional summing methods, it adjusts output based on stereo content, creating a wide, immersive stage for both driver and passenger.

Augmented Bass Processing – Enhanced Subwoofer Performance

With Dynamic Bass Enhancement and SubXpander, the M SIX DSP boosts deep bass response and adds harmonic richness without risking subwoofer overload. These proprietary features deliver punchy, detailed low-end across all volume levels and genres.
