This is a high-efficiency Class D audio power amplifier with a typical output power of 2*210W at 4ohm load.
It is powered by dual power source of transformer, can work normally from ±۱۲V to ±۲۸V.
Due to BD modulation, noise is low during normal operation.
Fixed frequency: clock switching frequency can be externally synchronized.
High efficiency, low static current.
Complete protection function: overvoltage protection, output current limit.
