HELIX P SIX DSP ULTIMATE

The HELIX P SIX DSP ULTIMATE redefines high-end car audio with a combination of massive power and cutting-edge digital signal processing. Delivering up to 285 Watts RMS per channel into 2 Ohms, and equipped with a 12-channel signal processor featuring dual 64-bit DSPs, this amplifier guarantees unparalleled sound quality in Hi-Res audio. Its Ultra HD Class D concept blends the rich tonal warmth of Class AB with the efficiency of digital amplification, placing it firmly in a class of its own.


High-Resolution Audio Powered by TwinDSP Technology

The amplifier features two powerful 64-bit digital signal processors (DSPs) from Analog Devices, capable of performing 2.4 billion multiply-and-accumulate (MAC) operations per second. Paired with 96 kHz sampling and Burr-Brown A/D and D/A converters, it achieves an audio bandwidth exceeding 40 kHz. Every component — from the power supply to the signal path — is optimized for pure, high-resolution sound.


ACO Platform – Next-Level Control and Sound Features

At the core of the P SIX DSP ULTIMATE is the proprietary 32-bit ACO (Advanced CoProcessor), delivering ultra-fast management of control tasks and advanced audio features. These include:

  • Augmented Bass Processing
  • RealCenter technology
  • ISA (Input Signal Analyzer) with channel-separated Input EQ
  • TuneEQ, an intelligent auto-EQ tool for precise frequency correction

The ACO platform also enables lightning-fast switching between up to 10 sound presets and future-proof firmware upgrades.


Versatile Inputs and Outputs for Maximum Compatibility

This DSP amplifier is built to integrate seamlessly with OE systems or aftermarket setups, offering:

  • 6x High-Level Inputs (up to 32 V RMS, with ADEP.3)
  • 6x RCA Inputs
  • 1x Optical SPDIF Input (up to 96 kHz)
  • 1x Coaxial SPDIF Input (up to 192 kHz)
  • 4x Line Outputs + 1x Optical Digital Output (SPDIF 96 kHz)
  • 1x HEC Slot (for USB or Bluetooth HD Audio streaming)

With Start-Stop capability (down to 6V), Power Save Mode, and Automatic Digital Signal Detection, the P SIX DSP ULTIMATE ensures robust performance and efficient operation in modern vehicles.


DSP PC-Tool 5 with TuneEQ – Professional Sound Tuning Made Easy

Configure and fine-tune your setup with DSP PC-Tool 5, the professional-grade tuning software. Featuring the intuitive TuneEQ tool, you can automatically calibrate EQs to match your target curve with a single measurement per channel, saving time while optimizing sound precision.


Highlight Features

  • 285 W RMS per channel (2 Ω)
  • Ultra HD Class D amplifier – High-end sound with Class D efficiency
  • Dual 64-bit DSPs – 2.4 billion MAC/s for advanced processing
  • VCP (Virtual Channel Processing) – Flexible system configuration
  • ISA & InputEQ – Analyze and correct factory-tuned inputs
  • Augmented Bass Processing – Dynamic Bass Enhancement & SubXpander
  • RealCenter – Expands sound staging beyond conventional center channels
  • Smart Control Port (SCP) – For remotes and expansion accessories
  • HEC Slot – Add USB or Bluetooth HD audio streaming
  • Optical digital output – Enables full digital signal chains
  • Power Save & Start-Stop Ready – Efficient and reliable in any condition

Special Features of the HELIX P SIX DSP ULTIMATE

Ultra HD Class D Amplifier Technology

Experience exceptional sound fidelity with Ultra HD Class D amplifier technology, which surpasses traditional Class D designs. Thanks to an advanced integrated feedback design, this system delivers a frequency response exceeding 40 kHz with reduced distortion, offering Class AB-like sound quality while retaining the efficiency of Class D amplifiers.

TwinDSP Power – Unmatched Processing Capability

Equipped with dual 64-bit Analog Devices audio signal processors, the P SIX DSP ULTIMATE offers a staggering 2.4 billion MAC operations per second. This TwinDSP Power architecture enables independent processing of 12 audio channels at a 96 kHz sampling rate, delivering pristine high-resolution sound across a wide audio bandwidth.

12 V and 24 V Compatibility

Whether your vehicle uses a 12-volt or 24-volt electrical system, this amplifier is ready to perform without requiring modifications—ideal for trucks and versatile installations.

Advanced 32-Bit Co-Processor (ACO)

The ACO platform handles control processes lightning-fast and enables near-instant switching between up to 10 sound setups. It also powers advanced features like:

  • ISA (Input Signal Analyzer) for factory radio calibration
  • Augmented Bass Processing for richer low-end performance
  • RealCenter for optimal front-stage imaging
  • TuneEQ, a revolutionary tool for automatic EQ tuning
  • Native boot loader for seamless firmware upgrades, including ADEP.3 updates and future expandability

ADEP.3 – Smart High-Level Input Integration

The Advanced Diagnostics Error Protection (ADEP.3) ensures flawless compatibility with OEM radios. It prevents error messages and function loss (like fader issues), even with modern head units that monitor speaker outputs closely, without overloading the radio at high volumes.

Start-Stop Ready

Thanks to its stabilized power supply, the P SIX DSP ULTIMATE maintains consistent internal voltage, even when vehicle battery levels drop to 6 volts during engine cranking.

Power Save Mode for Energy Efficiency

The built-in Power Save Mode shuts down connected amplifiers after 60 seconds of signal inactivity, reducing power consumption. The system instantly reactivates when a signal is detected. This timeout is adjustable via the DSP PC-Tool software, allowing full customization to your vehicle’s behavior.

Auto Digital Signal Detection

The amplifier automatically switches from analog to digital inputs (optical or coaxial) when a digital signal is detected. This feature is configurable in software and can be controlled manually with an optional remote.


Exclusive DSP Features

TuneEQ – Automatic EQ Calibration

TuneEQ makes frequency response correction intuitive. With just one measurement per channel using a measurement mic (e.g., MTK1), the system auto-adjusts EQ settings—including center frequency, gain, and Q-factor—to match your target curve. Save time while achieving precise tuning effortlessly.

RealCenter – Precision Front-Stage Imaging

RealCenter creates a dynamically balanced center signal by analyzing and blending shared audio content from left and right front channels. Unlike basic summing methods, it only outputs center audio when both channels contribute, resulting in a wider, more immersive soundstage for both driver and passenger.

Augmented Bass Processing – Deeper, Smarter Bass

This proprietary bass enhancement suite includes:

  • Dynamic Bass Enhancement: Automatically boosts low frequencies and adjusts subsonic filters based on input signal, offering powerful bass without overloading your subwoofer.
  • SubXpander: Generates subharmonic tones (50–100 Hz) for a deeper, darker bass experience.
