greg sextro Posted April 22, 2012 Report Share Posted April 22, 2012 I've read the documentation for the pinouts going into an iPad (4 pin mini TRRS), but my question has to do with attenuating the signal: According the the Movie Slate website, one should look to attenuate the TC signal by about -22db so it doesn't overload the mic input. Anyone know what rated resistor would do this? Would I just wire it inline of the hot signal and leave the ground untouched? Thanks, -Greg- Quote Link to comment Share on other sites More sharing options...
Eric Toline Posted April 23, 2012 Report Share Posted April 23, 2012 Try a 50 ohm resistor in series with the positive signal. Leave the ground alone. Eric Quote Link to comment Share on other sites More sharing options...
Derek H Posted April 23, 2012 Report Share Posted April 23, 2012 You could try the schematic that Ambient provides for their timecode app. I believe there is a .022 uF cap across the leads and also some sort of L-pad in place. Look up their time code cable for iPhone and then download the user manual which is really just the schematic. Quote Link to comment Share on other sites More sharing options...
