HELIX DSP PRO MK3 10-Channel Digital Signal Processor

HELIX DSP PRO MK3 – 10-channel digital signal processor

The DSP PRO MK3 combines ten processed output channels with TwinDSP processing for demanding multi-amplifier installations. Eight RCA and eight high-level input channels support system integration, with high-level sensitivity extending to 32V. Two 64-bit processors, AKM Velvet Sound 32-bit converters and a 96kHz sampling rate provide the foundation for detailed sound adjustment.

System integration and tuning

High-level and line-level connections allow integration with compatible factory or aftermarket sources. ADEP.3 circuitry helps accommodate factory speaker diagnostics, while the Smart Control Port supports compatible optional control accessories. The processor lets the installer tailor the system to the vehicle and speaker layout rather than relying on the source unit alone.

Installation notes

This is a stand-alone signal processor, not a speaker power amplifier. External amplification is required. Expansion cards, Bluetooth modules, remote controls and measurement equipment are optional and are not included. USB audio streaming on HEC-equipped models requires a compatible optional expansion module; the NEXT DSP ULTRA XT includes USB PerfectStream. Where a digital input accepts a rate higher than 96kHz, this does not change the specified 96kHz internal DSP sampling rate.

What's included

• 1 x HELIX DSP PRO MK3 signal processor.
• 1 x Control Input-to-SCP adaptor.
• 1 x USB cable.
• Mounting material.
• Instruction manual.
