This LJM module fulfills two essential functions: linear power supply and speaker protection with time delay during speaker start-up. It is capable of receiving voltages from 24-0-24V to 36-0-36V AC for a maximum output voltage of 2x +/-50V, thanks to 4 63V 4300uF filter capacitors. In addition, it recovers the signal in order to apply protection to the speakers, with a delay at loudspeaker start-up until the current has stabilized throughout the system. It goes particularly well with various LJM amplifier modules.
