SOURCE: 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.

SOURCE: Denon DRA-25/25L Stereo Receiver.

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 ;-)

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

I have a Denon (receiver) DRA-825ra that has this issue: It powers on and you hear the first click sound right away, but the second click sound after five seconds does not activate. Can you help me...


Try plugging in headphones to the headphone jack, then take the plug out. Some models of Denon receivers had faulty headphone jacks in them that caused the unit to think there were headphones plugged in even when there wasn't.

Listen for a relay clicking inside. It you hear it but get no power, it is a problem with the relay. If there is no click, it is probably the power supply.

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.

Denon dra 397 shuts done if I turn on both zone a & b. Have a 100 watt volume control on each pair of speakers. Works fine with only zone a or zone b on, but not both.


Let's understand this - you have an external volume control wired in series with each front speaker set?

Can you elaborate on their electrical characteristics?

I have a Denon receiver dra 545a that won't power on... how costly might it be to repair


Sounds like the power supply went out. Check inside to see if a fuse is blown. Replace it once (with the exact rating) and if it blows a second time, then you have something shorting out and can be costly to repair. DO NOT replace the fuse with a higher rating for it might cause a fire.
