Helix P Six DSP Mk2 (P – Series)

HELIX P SIX DSP MK2 – 6-Channel Amplifier with 8-Channel DSP

The HELIX P SIX DSP MK2 isn’t just an amplifier—it’s a complete sound optimization powerhouse. Merging a 6-channel Ultra HD Class D amplifier with an 8-channel high-resolution DSP, it redefines what’s possible in car audio performance and tuning.

Thanks to its 96 kHz sampling rate and audio bandwidth exceeding 40 kHz, the MK2 delivers an incredibly clean, high-fidelity sound experience—setting a new benchmark for Class D amplifiers with DSP integration.

Ultimate Versatility with HEC Expansion

To expand its capabilities beyond standard RCA inputs, the P SIX DSP MK2 features the HELIX Extension Card (HEC) slot. This allows seamless integration of modules such as:

• Bluetooth® Audio Streaming
• High-Resolution Audio via USB

It also includes two fully processed RCA outputs for daisy-chaining additional amplifiers without needing a secondary DSP.

Despite its powerful internals, the MK2 retains the compact, clean HELIX design, making it ideal for tight installations without compromising performance.

• Automatic remote switch-on

Special Features

Ultra HD Class D with 96 kHz Sampling

The HELIX P SIX DSP MK2 is the first Class D amplifier with integrated DSP to operate at a 96 kHz sampling rate. This enables a wider audio bandwidth (>40 kHz), made possible by the latest generation of amplifier and DSP chipsets. The result? Unprecedented clarity and dynamics for a Class D system.

12V & 24V Compatible

Whether you’re upgrading a car or truck, this unit offers full performance in both 12V and 24V systems—no modifications required.

Smart OE Integration – ADEP

Many modern factory radios monitor speaker outputs, often causing errors when aftermarket amps are connected. The MK2 solves this with ADEP (Advanced Diagnostics Error Protection), which ensures full OEM compatibility without triggering faults or impairing features like fader control.

Power Save Mode

To optimize energy consumption, the Power Save Mode turns off the internal amplifier stages and remote output after 60 seconds of signal inactivity. It restarts instantly when a signal resumes and can be customized or disabled via the DSP PC-Tool software. Ideal for modern cars with CAN or bus systems that keep the radio active even after shutdown.

Start-Stop Ready

Even during voltage drops as low as 6V during engine cranking, the internal switched power supply keeps the MK2 running smoothly, ensuring zero interruptions to your sound.

Auto Digital Signal Detection

Switching between analog and digital input is fully automated based on signal detection at the optical input. For manual control, use the optional remote or configure it via software.
