Description

The BI30020B is the very right choice for 2.1 channel or 2 channel audio systems. The BI30020B is a newest generation of pure digital amplifier that is embedded with Digital Electronic Crossover, 12V Speaker Driver & Earphone Driver. Directly input 2 channel digital audio data, the BI30020B will generate 3 sets of signal for Left, Right and Sub-Woofer Channels. Each set of signal can select crossover frequency and Sub-Woofer's phase to drive speakers without external complicated Filter circuit. The powerful Audio Volume Control includes power-on Initial volume function, 32-Level Audio Volume Control and Mute Control. It also provides Volume Boost and Anti-Clipping function. The quality of sound is pure and full which is much different from the traditional Class AB Amplifier.
