AJMRTC ZK2001 digital power amplifier board is a pure poststage audio driving module built around the TPA3221 highfidelity digital amplifier chip. It accepts DC 1030V power input and provides 100W plus 100W dualchannel stereo output under appropriate power supply conditions. This amplifier board supports bridged mono mode, which combines output channels to supply high power for subwoofer units to produce solid bass effects.
Being a pure rearstage amplifier, this board requires an external preamplifier to provide audio source signal input; it cannot work independently without prestage signal source. It fits multiple DIY audio scenarios, including homemade desktop speakers, cabinet audio system refitting, experimental audio equipment assembly and old speaker upgrade. Optimized circuit layout helps reduce signal distortion during highpower operation. Please confirm power supply voltage, speaker impedance and prestage signal matching before wiring to avoid module damage.
