I just purchased a used Denon AVR-3200 and have nothing hooked up yet but plugged it in on my kitchen counter and upon turning the unit on, noticed the error overload button was lit up but the unit did not shut down. Is this because there is nothing plugged into it yet?

The only way I know off is to unplug it. Standby simply tells you it is plugged in.

I don't not have DENON AVR - 3200 's manual. So please.

The setup mode can only be entered using the remote on this model of Denon receiver

Denon being one of the best names in the biz and this being an upper-crust modfel, I'd say anyone without a 'golden-ear' would be hard pressed to t\distinguish its sound from any other amplifier in existence.

The Denon site doesn't list and AVR-3200, but the AVR-3300 has 1 coaxial digital audio and 3 optical digital audio inputs.

If you're looking to run multiple coaxial devices and there aren't enough inputs this is what I do...

Helpful hint: Coaxial digital audio cables can be joined using an RCA cable splitter so they can share a given input or distribute a given output to multiple places. You just have to remember to have only the DESIRED units turned on when sharing or there will be digital confusion on the buss and it will result in silence or horrendous noise.

Seems you cannot fix this issue yourself. If the unit is still under warranty, Denon will replace a chip which has a flawed firmware. The unit cannot be updated remotely and a physical repair is necessary.

1) attach to front left and right or A left and right.
2) change balance by adjusting speaker levels
3) goto http://www.usa.denon.com

does the unit have a setup menu button on the front panel? if so push that, watch the display, use the up, down, left, right, select buttons on the panel to navi the menu. go online and look at a pdf user manual for the unit

I have a remote left over from my denon ACR3200. the remote is RC-825. It is currently listed on Ebay.

go into the settings and set ALL speakers to SMALL even if they're big and leave them that way.
Then, in the screen, say YES to sub.

What happens when you select options from the front of the reciever?....accordianman
