I am on call this weekend (covering for a colleague) so I am not going anywhere.
I was going to take a trip to Radio Shack to get the RCA Jack, cable, etc. to make a interface cable to the receiver when I realized that I have those in various places around the shack. So off I went to pull out, hack up, and wire in one side of a stereo RCA cable (note that I am working on one channel right now).
I pulled out my old DENON Stereo Receiver and one of the MINI ADVENT Stereo speakers. Dusting off was the first order of business but they wired up quickly and I had the MP3 preamp driving the CD Line input of the stereo to the single speaker. Next was to try my phone, and then finally the Tablet.
Below is a picture of the set up with the MP3 player and the Receiver. This set up also has the preamp powered by a 12VDC Brick, with the ATX power source removed.
After adjusting some levels and listening to the output of the receiver, I think I will alter the design slightly to give myself more gain (just feeback resistor values). The design already has a variable resistor such I can set the level when in place in the living room.
Waiting for my parts order to come in......Just about ready for figure out final design, connectors, packaging, etc.
