HELIX DSP.3S 8-Channel Digital Signal Processor

HELIX DSP.3S – 8-channel digital signal processor

An eight-channel digital signal processor for flexible aftermarket and factory-system upgrades. Six RCA and six high-level inputs, plus optical and coaxial digital inputs, provide versatile source connections, while eight 6V RCA outputs feed your external amplifiers. Its 64-bit DSP, BurrBrown converters and 96kHz sampling offer precise processing with extended audio bandwidth.

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.3S signal processor.
• 1 x Control Input-to-SCP adaptor.
• 1 x USB cable.
• Mounting material.
• Instruction manual.
