Velocity 8 Advanced Harley DSP, Amplifier, & Analyzer System SKU: Velocity 8 Short Block

Designed for Fully Active Speaker Systems

The Velocity 8 can be used in any traditional speaker configuration but is geared towards fully active speaker systems where each speaker (including tweeters) have a dedicated amplifier channel with independent gain and EQ. The passive crossovers are not used in active systems, so there are fewer items to cram into the fairing, and one less item to rob power from your speakers.

Product Description

The Velocity 8 Is the Perfect Solution for Anyone Who Needs Perfection

The key difference between the Velocity 8 and all other DSP units is that the Velocity 8 allows anyone to perform a tested and verified tune instead of just a theoretical tune. A standard DSP allows you to input your settings which are all just best guesses and based in theory. Even for a professional. The Velocity 8 is so well equipped with integrated test equipment that your tune ends up very precise and always verified down to the finest detail.

The Velocity 8 is the most advanced and premium digital sound processor for Harley applications ever made. The Velocity 8 combines all of the best DSP features with an entire suite of professional audio testing and tuning tools. The Velocity 8 also has an integrated 4 channel amplifier specifically for fully active sound systems. Now you no longer need to cram a secondary amplifier in the fairing for your tweeters to be on their own channels. This unit has a spectacular sounding amplifier built right in.

100% plug and play with your 2014 or later Factory radio right out of the box. We made power, accessory, and audio signal input connections all baby simple. And factory amplified bikes do not require a zillion bypass harnesses like other plug and play systems. Factory amplified and Ultra bikes only require one single additional harness, and that single harness works for all factory trims and options from non-amplified Ultra models to fully loaded CVO with multiple factory amplifiers. Even the new factory Rockford systems.
