The IMPEDER = Less than 10 ohms output from any piece of gear - Page 5

I don't know if this one is like mine, but if in mine I short the output, the relay automatically make a tric!!! and then the sound is cut, and a the screen read something like check the speaker cables, or something like that, so I'm not sure how those relays work, but have to be related with the audio signal in any way, unless the short, overload the power supply in any way, and this way the relay could act, I don't know but the relay acts when you short the signal, nothing related directly with the power supply, just with the signal....I would like that someone with more experience, will explain us how this things work, I'm curious now....

Well, my Onkyo doesn't start amplifying immediately after power-up either, but I managed to short it out dead, no problem. I'm on my second unit now

The delay is to protect your speakers (and phones) from turn on "thump" that most amps make when the power supply is coming up to operating voltage. It disconnects the output for a couple seconds, while the supply charges up. Since you removed the resistors from the circuit, which are there to protect the amp from momentary shorts (as mentioned earlier), instead, just turn the amp off before plugging/unplugging your phones. From your pictures, it looks like your amp uses an output ic, (like a gainclone) And many of the ic's have short circuit protection built in, but it is probably best to be cautious by turning it off.
