A crossover is an electronics device that takes a single input signal and creates two or three output signals consisting of separated bands of high-, mid-, and low-range frequencies. The different bands of frequencies feed the different speakers, or “drivers,” in a sound system: tweeters, woofers, and subwoofers.
In miniDSP we provide multiple crossover types such as:
- 2way crossovers: 2x4, 2x4 HD, 2x4 Balanced
- 3/4way crossovers: 2x8 kit, 4x10, nanoDIGI 2x8, OpenDRC Series
