If you recall the movie "The Graduate" there is just one word from the cocktail party scene that answers your point.

I don't know if your scheme would work but I do know that airport metal detectors have some way to discriminate between a key in my wallet and all the titanium and stainless steel in my arms, back, and pelvis. I used to set the things off but not any more. I have spoken with folks who have long pins in their legs, artificial knees, and artificial hips and they don't set off the airport metal detectors either. Eric |
| N_Cook <diverse@tcp.co.uk>: Apr 21 10:44AM +0100 Still cold exploration. 3 bad ESR SMD 10Uf 16V caps, marked 10 16S 014 on the digital board, one each on the Vcom pin of the ferret codec and the FX codec and another elsewhere, so could be injecting HF into the codecs. All other such caps ESR good Anyway hot testing next with Tx,Prea,PA spread-eagled across the bench. |
| N_Cook <diverse@tcp.co.uk>: Apr 21 11:51AM +0100 Disconnecting digital board ribbon disables the amp. Audio input to the digital board is constant and the output has the drop of level on it, then on to PA Owner only has the 696 user manual, f for ferret presumably. On the back of the amp it says press ferret button for 6 seconds to disable it. This it does, bringing level right up, beyond even switch on level. So if this is level 1 on a speaker, then at switch on goes to 1/2 that level and soon drops to 1/10 of it. Press for 6 seconds and comes up to level 1. So presumably HF injection is triggering attenuation, so I'll replace all 3 10uF caps and see what happens |
