What is the recommended voltage for the system power supply?
The recommended voltage for the system power supply is 15 V to 20 V.
How can I minimize distortion for the amplifier at high output levels and low frequencies?
Minimize the length of the power-supply cable as increasing length is equal to increasing the distortion for the amplifier at high output levels and low frequencies.
