What is special about One-Cycle Sound^TM?

OCS^TM is the fastest reacting PWM control law. It compares the audio input directly to the PWM waveform using non-linear feedback. This creates high-fidelity, transparent audio amplification. 

A typical PowerPhysics OCS^TM amplifier has 300,000 switching cycles per second. OCS^TM makes 2 corrections per cycle or 600,000 corrections per second! 

OCS^TM corrects:

• Audio signal changes
• Power supply noise and ripple
• Amplifier power stage (MOSFET) errors
• PWM rise and dead time errors

And it happens every 1.7 micro seconds. 

No other amplifier works as fast to deliver high quality audio.
