HKI Mini DSP – 8-Channel Digital Sound Processor for Motorcycle & Powersports Audio
The HKI Mini DSP is a compact 8-channel digital signal processor designed to give you full control over your audio system tuning in motorcycles, cars, UTVs and marine applications. Roughly the size of a mobile phone, it offers 4-channel RCA inputs and 8-channel RCA outputs with powerful EQ, crossover and time-alignment tools so you can shape your system exactly how you want it.
Who This Is For
- Multi-amplifier Harley Touring builds running front, rear, saddlebag and subwoofer channels from one processor.
- Riders who want EQ, crossover and time-alignment control to work around harsh motorcycle acoustics.
- Systems keeping an OEM radio, where the factory EQ and frequency response need correcting before the amplifiers.
- Riders who want separate tunes for solo, two-up or parked listening, using the three user presets.
- Tuning is done from a smartphone, and it connects by RCA – four inputs in, eight outputs to your amplifiers.
Key Features
- 4-input / 8-output DSP architecture – perfect for multi-amp, multi-speaker systems.
- Smartphone-based setup – designed for mobile programming and easy tuning access.
- Conformal-coated PCB to help protect against moisture and harsh environments.
- High-resolution 32-bit processing with 96 kHz sampling for clean, detailed sound.
- Input EQ (15 bands) and output EQ (8 bands per channel) for precise tuning.
- Advanced crossover options – Linkwitz-Riley, Butterworth, Bessel up to 48 dB/oct.
- Time alignment per channel to centre the sound stage at the rider’s position.
- Built-in limiter with adjustable threshold, attack and release to protect your speakers.
- Three user presets so you can switch between different tuning profiles.
Why It Works on Harleys & Motorcycles
- Small footprint – easy to hide in the fairing, saddlebag or under a side cover.
- Conformal coating helps it survive in bikes, buggies and off-road gear.
- Fine control over EQ and time alignment to overcome harsh motorcycle acoustics.
- Ideal front-end for multi-amp systems running front, rear, lids and subs.
- Preset switching lets you have different tunes for solo, two-up or “parked and loud”.
Recommended System Use
- Harley Touring audio builds: Integrate with multiple amplifiers for front, rear, saddlebag and subwoofer channels.
- Custom bagger systems: Perfect for pro-audio style speakers and staged upgrades.
- UTV / SxS / Marine: Tune multiple speaker zones from a single compact DSP.
- OEM radio integration: Clean up factory EQ and correct frequency response before your amps.
Fitment
- Suitable for Harley-Davidson® Touring and other motorcycles.
- Also ideal for cars, UTVs, marine and off-road audio systems.
- Compact size allows mounting in fairings, saddlebags, side covers or amp racks.
