Circuit Topology
The XPA C Gen3 is a fully modular audio power amplifier with a high-efficiency switch mode power supply (SMPS), independent, fully discrete,
dual differential, high current, short signal path Class A/B amplifier modules, Optimized Class H™ power supply topology, and microprocessor-controlled fault
protection.
The XPA C Gen3 is powered by a high efficiency, audiophile grade, Switch Mode Power Supply (SMPS).
