I have a house that already has internal audio installed. Each Room has a volume control and 1-2 speakers installed. The odd thing, all runs only have 2 wire runs to each room, essentially a MONO setup. I'm guessing the design was due to some rooms only having one speaker (bathrooms etc.). The problem is my receiver doesn't have a MONO mode. So I only hear one side of the track.
My setup is an iPod in a iPod docking station outputting to a 1/8 stereo to dual RCA cable, which is fed into the AUX ports of an older Kenwood VR-405 receiver. Being that the house is not fitted with conduit, running the additional source line to the volume controls will be very costly.
Is there an easy and inexpensive way to convert the output from the Kenwood into a Mono signal? I did try a Radio Shack Stereo to Mono converter running off the iPod dock, but would not output anything but a rhythmic clicking noise. I removed the adapter, and sound returned. Yes, odd I know.
I've heard about the resistor method, but also heard sound quality is greatly reduced.
Just looking for ideas
