air-ship Posted February 17, 2009 Report Share Posted February 17, 2009 Hi all. Comm system mod. Does anyone know about the Radio Shack amp wiring modification to power the input socket? I've experimented with adding a AAA battery onto my Mic feed which does work. A bit noisy though. I also saw a comment about a resistor mod. I'm currently using a powered Mic which is no problem apart from an extra battery and an extra box. This is a good solution in that the mic signal is very clean. I would prefer to dispense with the extra box and battery and use a passive Lavalier mic. Any enlightenment would be greatly appreciated. Rees.

Rees. If anyone is interested in this topic, I now have the pictures of the modification courtesy of TK4205: I'm going to try this without a resistor. I'll check the voltage being fed to the input jack. I suspect it may be too high but I'll give it a whirl. Thanks to SuperTrooper for getting me on the right track with this topic.

CureMode[TK] Posted March 6, 2009 Report Share Posted March 6, 2009 I did the mod without any resistor and it seems to work fine if done like this (notice the red wire in the lower left). For me its been working fine for over 6 months and it amplifies my Radio Shack PC non-powered Mic. Quote Link to comment Share on other sites More sharing options...
TK4205 Posted March 16, 2009 Report Share Posted March 16, 2009 I have yet to try this mod. I might do this so I can offer some more input. Quote Link to comment Share on other sites More sharing options...

byetter Posted June 5, 2010 Report Share Posted June 5, 2010 Hey guys - Just wanted to add that I just used the standard wire jumper and it worked awesome. Now I need to find a descent mic. Quote Link to comment Share on other sites More sharing options...
