Record Player
When connecting a record player with an MC cartridge, use a
commercially available MC head amplifier or a step-up transformer.
Induction humming (a booming sound) may be produced from the
speakers if the volume is raised with no record player connected.
With some record players, noise may be generated when the ground
wire is connected. If so, disconnect the ground wire.
