ODEP stands for Output Device Emulator Protection. ODEP is an analog computer simulation of the output device thermal impedance. In layman's terms ODEP stores how much power the amplifier delivers to its load and its heatsink temperature. If the protection circuit determines that the output stage is being overstressed or cannot dissipate any further heat, then output stage drive is limited (Also see the FAQ, "What is TLC?" below). What is TLC? TLC, Thermal Limit Control is used in K-Series amps to provide the amp thermal protection, when a predetermined temperature threshold is reached, the TLC light(s) will begin to glow. This means the temperature sensing circuitry is starting to engage the input compressor. By compressing the input, the amplifier will not generate as much heat and will have a chance to cool down. The degree of compression is directly proportional to the amount of overheating experienced by the amplifier.  |  IP: Logged Antonio Marcheselli Phenomenal Film Handler Posts: 1260 From: Florence, Italy Registered: Mar 2000 posted 02-20-2003 04:53 PM                        Thanks Michael I've read the manual, I just would like to have a confirm that this happens!!

Unless they managed to fool the patent office, I would think that ODEP really happens.  |  IP: Logged
