Audiofrog A600.1D High Fidelity Class-D Amplifier

  • Board layout is a key component of a high fidelity amplifier design, especially when miniaturization is a key feature. Audiofrog HiFi Class-D amplifiers incorporate a four layer PC board that helps to isolate the magnetic circuit in the power supply and Class-D modulators from the amplifier’s preamp and audio sections. Small I/E transformers oriented to place the preamp circuit in a magnetic null replace the toroidal transformers often used in larger designs. High speed switches responsible for power supply and output voltage are located on the opposite side of the board from the preamp and audio circuits and are isolated by an internal shield layer. Heat is transferred from the switches on the bottom of the board to the heat sink on the top through heat sink pads incorporated into the top and bottom PC board layers.
