[QUOTE="Mitchell Fosgate III, post: 8887012, member: 691623"] [JUSTIFY]How'd you manage that? It comes back on when you turn down the volume? The volume control knob are equipped with variable resistors. Turn the knob on and increase it, the volume goes down because the current flowing through it decreases. Turn the knob down a bit to half way, the current then increases. Volume up again. The electronics behind protect mode is that the semiconductors are in saturated mode way too long, the amplifier then shuts down at that point. No way to reverse it after the diodes and mosfets are in saturation mode for too long. It should be in the active mode, or cutoff mode. On or off, is the cuttoff mode. Referring to these variable resistors, the cutoff mode. Have to get it fixed once in the protect mode. There's a zener diode or the zener break-down ( PIV ), peak inverse voltage. But these zener diodes operate in reverse bias for not a long time. After that they break down. Called the zener peak inverse voltage diode breakdown point. It is referring to the avalanche effect. The point the amplifier is about to break down. At which point the amplifier is already in saturated mode and signals a protect mode. Zener peak inverse voltage voltage is peaked or maxed out in the reverse bias direction. As it relates to op amps and the linear amplifiers talked about here.[/JUSTIFY] [/QUOTE]
