My Denon Audio precision am fm DRa 435R Reciever will not stay on station very long. After about 30 or sometimes 45 minutes it get off station. I have it set to a local FM Station, 97.9 and it plays good...


OK,this is a fairly common problem with digital tuners, I get them from time to time in my shop, you see, what is happening is the voltage that's used to tune the set, usual;y stays rock solid, your device however is drifting off station due to this voltage changing, usually it is in the powers supply or the actual tuner itself. It can be bad capacitors, bad IC's, bad transistors, bad tuner module. Sometimes it maybe a "Dry Joint" too.
The only fix is either a replacement PSU or Tuner or indeed maybe both? One simply cannot tell exactly without examining the unit.

You need to take this unit into a Denon repair center and ask for a "Quote" as to costings etc. Once appraised of that one can proceed from there?
Contact a Denon head or local office and ask them there, for a referral to an authorised service center.

Check on the back of the unit for a switch marked "channel step" or something similar.Usually close to the anntena socket or connection.When you find it switch it to the alternative position.This should solve your problem.

My denon DRA-295 does not remember stations I set to memory when completely turned off. If on standby all goes well. A month after the problem mentioned above the tuner started to modulate reception and...


My better guess is a CMOS chip is either bad or there is a cold solder connection in the vicinity. If the power supply is bad, the receiver would not power up.

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.

Denon receiver (DRA 397) will not speak to iPod dock


IF YOUR NOT USING A DENON IPOD DOCKING STATION IT WILL NOT FUNCTION CORRECTLY.
YOU CAN CONNCET OTHER TYPES OF IPOD DOCKING STATIONS BUT YOU WILL NOT HAVE CONTROL THROUGH THE DENON AND ONLY CONNECT THE AUDIO FOR THAT DOCKING STATION TO THE DENON AS ANOTHER SOURCE INPUT
