Question about Denon AVR-485 Receiver

AVR-485 Quit working

This summer, while hosting a cook-out, my receiver quit working half way through the evening. The volume was up, but not excessive (little more than half way). As of now, I can still "turn the unit on and off" and see the red/green light behind the power button...as well as the option buttons on the lower panel, but the LED readout has quit working, thus rendering the unit dead. I pulled the cover and checked the fuses, but they seem to be fine. Is there something else I can check, or is the unit actually dead?

    Thanks for the input, but it didn't work for me :(



    When pressing the speaker A and B buttons, the entire readout doesn't flash...only the 6 red lights below the display. I tried it for varying amounts of time, but no luck.



    Thanks again for trying

I just bought this machine...and had earlier seen your post. I was looking at the "microprocessor re-initialization" part and thought, hey, it may be worth a try for you.

So, consider re-initializing (resetting) the machine. This can be done by:

1) Turn off the unit using the *main* power switch
2) While holding both Speaker A and B button, turn on the machine using the *main* power switch
3) You should see the main display flash at 1 sec intervals. Let go of the speaker buttons to finish.

Hope it helps,

Eddie V.

Hooking up ipod


THe easiest way to hook an iPod or any other personal audio player to almost any audio receiver is to pick up a cable having a stereo miniplug (like the plug on your earbuds) on one end, and two RCA plugs on the other end. You should be able to get this cable from almost any electronics or discount store for under $10. The miniplug goes in the iPod's earphone jack, and the RCA plugs connect to an unused input on your receiver. Inputs marked "AUX" or "CD" are a good choice, or even a "TAPE" input. Set the iPod to about 3/4ths volume and adjust the receivers controls for desired volume.

Turning volume up on my Denon AVR-485 AMP causes it to turn off


Speaker Impedance:
When speaker systems A and B are used separately, speakers with an impedance of 6 to 16 ohms can be connected for use as front speakers
Be careful when using two pairs of front speakers (A + B) at the same time if their impedance is less than 12 ohms.
The protector circuit may be activated of the set is played for long periods of time at high volumes with an impedance lower than specified are connected.
