New! The Minifilter 2 Kit - It's back, and there have been a few changes!

Building upon the success of the Minifilter DSP kit we're delighted to announce the release of the latest version, the "Minifilter 2". Similar in size to its predecessor, the Minifilter 2 packs many new features including variable band pass filtering with rasor sharp transition bands and binaural audio. Its ability to store complete operating configurations make it ideal for embedding into existing equipment as an audio upgrade.

If you've already put an X-Lock into that old radio to cure its drift, add the Minifilter 2 for the ultimate upgrade and benefit from DSP filtering and a host of other features.

Alternatively, use it as a stand alone audio processor or build into into a speaker to make an amplified speaker unit with ultra sharp DSP filtering. Find out more on the Minifilter 2 page.
