Gabe,
I might be able to help you out with your technics receiver since I have the same receiver and have programmed my av producer 8 to work pretty well with it.
I first and foremost have to direct you to Rob's fantastic web sight on this remote control where you can find out how to program "advanced codes":
[Link: stormloader.com] Then you can find the "advanced codes" for the amplifier portion of the receiver at:
[Link: stormloader.com]or at
[Link: xi6.com]the last site (bruce tomlin's site) is where you will find the most accurate "advanced codes" for the tuner portion of the sa-dx930. Bruce Tomlin's site is for a different Technics product (sa-ax720) but the codes work just fine with the sa-dx930. On the amp section alot of the names are different than what you have become accustomed to on the sa-dx930 but if you play around enough with it you will get it. Remember the tuner and the amp have to be programmed seperately on different "mode" buttons on the remote control. (AMP device code: 0308 ; TUNER device code: 0309)
I'm not an expert at this. I've relied a great deal on this website for tips and tricks. Most of it was trial and error but with enough work I finally got it. Good Luck.
