I also tried Audio Amplifier code 0892 with no luck. Sorry, I should have mentioned in my original post, I've already tried Audio Receiver code 0110 (it's actually listed in the manual for the URC-8910). I think doing a test with Audio 0110 is more robust than just loading a WAV file. If not, we'll need to search a little bit. If so, we'll make a WAV file under the assumption that the HK 3490 uses the same signals as the AVR series. Please try setup code Audio 0110, and see if Vol + or Vol - work. The 8910 has a built-in setup code which will control some of the functions of the AVR series. So it isn't clear if the HK series uses the same IR signals (NEC1 protocol, device 128.112 and 130.114). The upgrades here are for the AVR series of HK components. But in the meantime, if someone could post a WAV for this upgrade, I would really appreciate it! I plan to order a JP1 cable in the near futures. Also, sometimes it took several button presses to just get through once. Also, I'm not sure volume up was learned 100% correctly, because holding the button down only sends one signal, instead of a repeating signal. Learning remote question? I was able to teach the volume up button, but not volume down. Checked Pronto file section (at R/C)? Yesġ0. JP1/UEI Remote model: One For All URC-8910Ĩ. Year: 2009 or 2010 (still in production)Ĥ.

I don't think you'd ruin your speakers, if you don't push it too loud, but that being said, you could try to get a better amp for what you bought. Into 4-ohm loads, the HK 3490 exceeded its 150wpc power rating by putting out 167wpc x 2 0.1% THD + N and a whopping 227wpc of dynamic power with both channels driven. In fact, the amp section in this receiver was so stable that I ran all of the power tests with both channels driven and the HK 3490 never complained or broke a sweat during my torture tests. It came very close to running both channels at continuous full rated power (120watts) and held up well for the 1kHz 8-ohm and 4-ohm power vs. The harman/kardon HK 3490 power reserves were quite impressive for a receiver of its price and size.
