Helix V Eight DSP (V – Series)

HELIX V EIGHT DSP MK2 

The HELIX V EIGHT DSP MK2 is the next evolutionary step in HELIX’s world-renowned amplifier series, designed for professional installers and serious audiophiles. While it retains the sleek aesthetics of its predecessor, this second-generation model features a completely redesigned hardware architecture that redefines performance, flexibility, and audio fidelity. With 8 channels of Class GD amplification and a 10-channel DSP powered by a 32-bit ACO CoProcessor, it offers uncompromising audio quality and advanced tuning options for even the most complex OEM integration projects.

Key Features & Benefits

Enhanced Speed and Control – Powered by ACO Platform

At the heart of the V EIGHT DSP MK2 lies the ultra-fast 32-bit ACO (Advanced CoProcessor). It manages all control and communication functions, enabling lightning-fast setup switching and seamless interaction with the DSP PC-Tool software. The ACO platform also enables advanced features like:

• Augmented Bass Processing
• RealCenter Imaging
• Input Signal Analyzer (ISA)
• Channel-separated Input EQ

These enhancements ensure precise tuning and effortless signal analysis—ideal for adapting OEM signals from factory systems.

High-Resolution Audio – Superior Signal Conversion

Unlike traditional combined-codec systems, the V EIGHT DSP MK2 features dedicated AD/DA converters from Asahi Kasei, offering true 32-bit native resolution. This guarantees the highest signal integrity from input to output, preserving every musical nuance with unmatched clarity.

Virtual Channel Processing – Smarter Signal Routing

The exclusive Virtual Channel Processing (VCP) architecture revolutionizes how audio signals are routed. It simplifies complex system configurations involving multiple mixed input sources, multi-way systems, and custom FX assignments. VCP empowers you to:

• Build intricate signal paths
• Customize routing with intuitive control
• Assign DSP features like RealCenter and Bass Processing across any channel

Maximum Input Versatility

Designed for seamless OEM integration, the V EIGHT DSP MK2 supports a wide range of input options:

• 6 RCA / Cinch inputs
• 8 high-level inputs (up to 32V RMS)
• Integrated ADEP.3 (Advanced Diagnostics Error Protection) circuit to avoid OEM radio issues
• Smart auto-detection and seamless compatibility with modern factory systems

Whether you’re working with standard head units or advanced factory amplifiers, this unit adapts easily without triggering diagnostic errors.

Powerful Output – Pure Class GD Technology

Each of the 8 channels delivers up to 160 W RMS @ 2Ω, making the V EIGHT DSP MK2 a true powerhouse. The proprietary Pure Class GD amplifier design optimizes efficiency by varying the internal supply voltage based on input signal strength. Benefits include:

• Low heat dissipation
• Compact design
• Superior sound quality with fully differential signal path and improved output filtering

High-Tech Design in a Compact Body

Despite its cutting-edge capabilities, the V EIGHT DSP MK2 maintains a compact footprint and elegant HELIX styling. Its clean, professional design allows easy installation while keeping heat generation to a minimum—perfect for confined vehicle spaces.

Advanced Audio DSP Features

TuneEQ – Automated Acoustic Calibration

TuneEQ makes tuning easy. With just one measurement per channel using a compatible microphone (e.g., HELIX MTK1), the system auto-adjusts all parametric EQ settings to match your desired reference curve—saving time and ensuring accurate sound optimization.

RealCenter – Intelligent Center Channel Processing

This exclusive algorithm extracts center information from left/right signals and dynamically adjusts based on stereo content. The result? A natural, wide soundstage that feels immersive for both driver and passenger—without sounding artificial or cramped.

Augmented Bass Processing – Deep, Dynamic Bass

This dual-mode DSP feature includes:

• Dynamic Bass Enhancement – Enhances low-end clarity at all volumes without risking speaker damage.
• SubXpander – Adds subharmonic frequencies for darker, deeper bass response between 50–100 Hz.

Additional Highlights

• Start-Stop Ready – Operates reliably even if battery voltage drops to 6V during engine start
• Power Save Mode – Automatically reduces power consumption when no signal is detected
• HEC Slot (HELIX Extension Card) – Add Bluetooth® streaming, high-res USB audio, and more
• 2 Processed RCA Outputs – Expand your system with external amplifiers
• 1:1 IOR (Input to Output Routing) – Precise mapping of input signals to amplifier outputs
