    ... Power Supply (PSU) Interface (J901 and J900) The TAS5508-5142K7EVM module must be powered from external power supplies. High-end audio performance requires a stabilized power supply with low ripple voltage and low output impedance. Note: The length of power-supply cable must be minimized. Increasing length of PSU cable is equal to increasing the distortion for the amplifier at high output levels and low frequencies ...
