Digital Signal Processors (DSP)

Motorcycle DSPs for Harley-Davidson® Touring, including the Cicada DSP412PRO, the Hertz S8 standalone processor and Cicada FLX PRO amplifiers with DSP built in. A DSP gives you crossovers, equalisation, level and time alignment for each channel, so the system can be tuned to where you sit rather than run flat.

A DSP amplifier suits most builds, while a standalone processor suits a larger system that needs more inputs, outputs and control.

Which DSP suits your Harley audio build?

This collection carries the Cicada DSP412PRO, a configurable processor with up to four inputs and twelve outputs, DIALD software and a published IP65 rating, the Hertz S8 standalone eight-channel processor, and the Cicada FLX700.4PRO and FLX1400.4PRO amplifiers with onboard DSP. The earlier Cicada DSP88V2 remains listed for reference, but the DSP412PRO is our current recommendation for a new Cicada standalone-DSP build.

FAQ

Standalone processor or a DSP amplifier?

A DSP amplifier such as the Cicada FLX PRO puts power and tuning in one compact box, well suited to most builds. A standalone processor such as the DSP412PRO or Hertz S8 suits a larger system needing more inputs, outputs and control.

Which Cicada DSP should I choose?

Our current recommended Cicada standalone processor for a new build is the DSP412PRO, with up to four inputs and twelve outputs, DIALD software and an IP65 rating. The earlier DSP88V2 stays listed for reference.

Is the Hertz S8 an amplifier?

No. The Hertz S8 is a standalone DSP with eight processed outputs. It provides signal integration and tuning but requires separate power amplifiers.

Do I need a DSP?

Not for a basic upgrade, but a DSP is what lets you align the front stage and set crossovers precisely, which makes a real difference on a bike. See the DSP amplifiers.
