I just purchased a 15-1994 and I have it running my TV, digital cable box, VCR, DVD player, AM/FM tuner, and cassette deck. My problem is that I can't find a code for my remote-controlled integrated amplifier, the Audio Refinement Complete. I called the RS 800 number and was told that there was no code for my amp. I programmed the amp remote's up and down volume keys, the mute key, and one direction of the input source selector onto the 15-1994's four smart keys, but I would much prefer to control the volume and source selections with the 15-1994's volume button and channel selector. Can this be done? Any help or advice would be greatly appreciated. Thanks!
