The Shakmat HiPass is a 2HP module that features a tetralogy of fixed frequency high-pass filters. Filters one and two are two-pole with their cutoff frequency set to 30Hz, meaning that this set of filters serves as a great solution to remove DC offsets from your sounds, and is also great for cleaning up your low frequencies so that you can maximize the energy of your speaker output. The second pair, filters three and four, are three-pole filters with a cutoff frequency of 100Hz. This set of filters is perfect for keeping your sounds clean of any unwanted low energy.
