HELIX DSP ULTRA S 12-Channel Digital Signal Processor

HELIX DSP ULTRA S – 12-channel digital signal processor

A twelve-channel stand-alone DSP designed for sophisticated multi-way audio systems. TwinDSP processing supports eight input channels, eight virtual channels and twelve output channels, with 8V RCA outputs for connection to external amplifiers. AKM 32-bit conversion, a refined analogue input stage and high-quality TI/BurrBrown OPA-series operational amplifiers support low-noise, low-distortion signal handling.

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 ULTRA S signal processor.
• 1 x USB cable.
• Mounting material.
• Instruction manual.
