I Have an Unwanted 5v coming down a video Intercom line just wondering if i could put a Cap in Series with the line if that would achieve any thing or if you guys had any other ideas.?
Thanx
Look Here -> |
I am Um sure of the system i only got told about it and thought to my self this might work but it is causing a static noise in the system on the Audio side ...
The system probably needs this voltage for a loop-current signalling system, or to supply bias for FET microphones etc..
Crackling in such a system usually indicates a noisy switch or connection, maybe check its cable terminations.
hey thanxs yeh i will let them know then see how it goes..
If the unit is part of a mass produced system then it would generally already have the required DC blocking installed, if it was necessary.
