Trying to finish up my Aspen MAX/IFD install and we hit a problem - I have 5 inputs to connect but there are only 4 available.  Is there a way to combine two into one or another way to connect 5 inputs.  I have IFD 550, 540, TAS 605/A, Aspen MAX and I need to connect the Voice Alert box for my Gear/Stall Warning system.  I don't really consider any of those to be "optional" so I don't see how the front panel jack input could be used.  Any suggestions?

There are issues to be considered when combining audio signals.  It can certainly be done, but not likely using a passive combiner cable.  Some form of mixer would be needed.  See this informative explanation:" rel="nofollow -
