TZ SMART D-750-7 Micro Controller Board Electronic Hobby Kit

A crossover network divides an audio signal into multiple frequency bands. This is done to optimize which frequencies are directed to multiple speaker drivers, for example, a woofer for low frequencies and a tweeter for high frequencies. This is a best-in-class crossover audio speaker frequency divider module. The max current it drives is 25 watts. It has over current, overload, and short circuit protection features. The circuit design uses inductance ground connection, low-frequency signal attenuation increase so that the treble is more pure, bright, and clear.
