Each channel has its own supply with six 2,200µF capacitors and a 15A-grade high-frequency filter, reducing power noise and crosstalk, and capacitors placed directly in the amplification circuit supply energy on demand.\u003c\/p\u003e\n\u003cp\u003eSwitching at 700kHz cuts MOSFET temperature by 30%, according to NuPrime. The input circuitry is fully balanced, and the power and Class D modules sit in custom metal enclosures that shield them from electromagnetic interference and prevent mechanical hum.
