Description
Amplifier Power Supply & DC Protection
This unit will power two power amplifier modules up to 3A using a 300VA toroidal transformer. It will also provide turn on transient muting plus DC protection in case an amplifier module fails and outputs DC. This will protect expensive loudspeakers from instant destruction.
