Open Question

No sound output after a few seconds

I have fixedx a problem output (changed pwr xtr) on one channel of a Denon DRA 365a..when i turn the unit on ity would play for a few seconds and then the relay would turn of but still have power on the unit..I have trace a 1kc signal up to the output xtr, but one channel seem to be lower that the other, and all the voltages on both channel are equal.

Unplug receiver from AC outlet, and plug back in. The power reset should clear up the problem.

Check that your speaker cables are not touching each other at the amp end and also at the speakers as this will cause the amp to shut down.

hope this helps.

Without looking at the schematics for this particular model, I'd surmise that the click is indeed a speaker protection relay. Generally this is fed by a number of different sense circuits that watch for power amp issues and/or excess speaker current and/or power supply output stability. Although the relays do indeed fail at times, generally it is not the relay that is at fault. If you have a scope and a schematic, you can check the various circuits that feed the relay for the exact cause. If not, you can do some experiments that might help deduce the problem: e.g. do headphones work when speakers do not, does the relay click on when no speakers are connected (or selected), etc. In my experience, it is most often the output transistor(s) in the power amp. But not always ;-)

Check in the amp section for a short on the output transistors. It may need a resistor or two also. I doubt that it would be in the power supply.

SOURCE: denon dra-95vr receiver has no sound out. All

Right on!
Jumpers was my problem. Luckily I had a pr. of short RCA's because my NAD jumpers were too small to reach across.

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.

I turn my unit on and it turns off after a few seconds


After about 10 minutes of play time the power light goes from green to red and the system shuts down.

Denon DRA-397 - the stand by button light is blinking red and I have tried the reset but it did not work. Does anyone have any other ideas?


You may want to check your output transistors,They are the ones mounted to the big heat sink.With a ohm meter measure across one of the legs to another there should be no shorts.If you see anything burnt that channel will be bad causing the unit to stay in protect mode to prevent futher damages

Denon dra-95vr receiver has no sound out. All


Two things to check. First, the 95VR can be deceiving because it has a "variable loudness" control that some may mistake for volume. The actual volume is controlled by the big up and down arrows on the upper right side. If the volume is turned up, you should see the volume bar graph display show up. If none of the inputs are giving you volume, and the volume is turned up, then try running the output from the processor loop output in the back to another amplifier. The processor out is jumpered to the processor in for normal operation. Missing jumpers could cause a problem also. If there is sound coming to the processor out, then you have a problem with the power amplifiers. Best to refer that to a technician.

I want to know how many watts, the denon dra-375's output is? my brother-in-law gave me this unit and the cover's became diattatched off the back of the all the pot's. i am still in the process of putting...


The unit is rated at 120 watts total output ( 60 watts per channel x2 channels) As far as being worth fixing it depends on the price of the parts and what you want to do after its fixed. I looked around a little and the unit gets good reveiws from owners. They say its great for a "just music" system.

Receiver cuts inself off about 15 seconds after you turn it on


you need to check your speakers connections to make sure nothing is touching and all is connected right and not to have to many spkrs on the channels, also only have the skrs on that you are using, make sure zone 2 / 3 are off and multi volm is turned down

No sound to speakers with power on


OK. That tells me that the output section is good. This may sound silly, but check to be sure that the tape monitor switch is not on.

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).
