    ... PSU Interface 2.1 PSU Interface The TAS5508-5122C6EVM module must be powered from one or two external regulated power supplies. High audio performance requires a stabilized output stage 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 ...
