    this problem is happening on all functions. Receiver has worked fine until just recently. It did smell hot recently and I don`t know if it was exact same time right channel stopped working.The pre out/main is not connected to any other equipment. The receiver connects to a Niles SPS-6 speaker selection,all 6 sets of speakers work with same problem. I do not see a location of a fuse on rear of receiver for speakers. Do I need to remove cover on the receiver to locate this fuse? Thanks you people!!

Check the pre out /main in jumper there should be a loop jumper for both left and right. if you are using a graphic EQ check the wires connecting to the receiver and the EQ. also is this happening on all sources?

    Ok, if you smelled something hot that is a good indication there is a problem internaly. maybe a resistor has opened or circuit has opened (fuse). if a fuse or resistor has opened up there is a chance the right channel amplifiers have shorted. there is a simple way to check to see if the amplier is good, disconnect the left speaker then slowly turn up the volume and listen to the right speaker if you hear a soft hiss the amp is running the next step is to check the preamp cicuit and the input ciruit. if you don't hear the hiss the amp is bad. there is one other thing that might be the problem is the speaker relay. this is a double switched relay (one for left one for right). it may not be making contact on the right side. any way it's internal to the receiver.

  • 204 Answers may want to check the speaker fuse, located on the rear of the unit.. sometimes too small wattage speakers get hooked up and the speaker fuse will blow as to not hurt the speakers.
Hope this helps.

Hi i have a denon dra 685 and when i hook up the speakers i barley get a sound out of it im thinking one of the channels may be out but is there a way i can reset the system as i was given the amp

Hello. My name is Dave. Does this unit have a tape monitor button? If it does, you probably have it switched on. Make sure you turn down your volume before turning the tape monitor off. If not a tape monitor, it may may another switched path that you have engaged. Same fix as above.

What can i do to be able to take my denon dra685 out of protection mode??????

I just recently picked up a Denon DRA-685 receiver that was stuck in protection mode. I found a site online that suggested it was due to two bad resistors on the main circuit board. More specifically resistor R-105 and R-106. They are both 1 ohm x 1 watt resistors. I ordered these from a supplier on Amazon for a few dollars, and just snipped the old resistors off, leaving the soldered leads sticking out. I then thinned the new leads and soldered them to the protruding wires, so I didn't have to remove everything. The unit now works like new. I'm happy I spent the time doing this, and grateful to the tech who discovered the common problem with this unit. Hope this can help somebody else. H

How do i hook up an ipod to a denon dra-685?

you can use a 1/8 inch female to stereo RCA adapter and plug the patch cable into one of your inputs like DVD or CD player. The signal to noise ratio on those inputs is pretty good.

The standy light continues to stay on

My CD player does the same thing. i need to press the power off button 2X then it'll power off. If it keeps doing it the easy way to correct it is to hook all you devices into a surge breaker and power off the unit.

Connecting new tv to DRA-685

you can use the headphone jack just get an adaptor to change from the headphone type to RCA type. adjust the volume of the tv to 3/4 of the way to give line level to the stereo, use an aux input on the stereo. if you had a suround sound dolby digital / DTS receiver then use the digital coax out to that type of receiver, but since you have an anolog 2 channel receiver you must use the only anolog source (the headphone).

Could it be that the speakers load is too much for the amp to handle? What are the ohm ratings? It should handle a low load but I am just wondering? How effcient are they?
