In this video 'Class D Amp meets SMPS - the TPA3255 300W x 2 meets 600 Watt SMPS', I'll showw the noise from the SMPS and how it shows matched with the Class D 300Watt x 2 Power Amplifier. The Class D amplifier is powered by the Texas Instruments TPA3255 Power Amplifier. This is a video to see if the Switch Mode Power Supply is acceptable to power an Audio Amplifeir.
