Question about Marantz SR-92 Mark II Receiver

1 Answer

Hi, I have a SR92 which intermittantly cuts out on the right side only. If I quickly flick the volume knob up past about a third the speaker kicks back to life. Doesn't seem to be a pattern to it and I don't believe it's the volume knob itself as there is not crackling or anything at all when using. Just cuts out clean then back in if I turn it up. Any ideas please?? Thanks Ricky

Is it on all audio sources or only certain ones? Have you swapped the speakers Left-to-Right to isolate the speaker from the signal chain as a cause?


If it's only an analog source doing it I would suspect a bad audio cable or a switch contact somewhere in the signal path. Typically, it might be a switch you rarely use, like a Tape Monitor or Mute. It's wise to occasionally (with power OFF) manipulate all manual controls throughput their ranges a number of times to wipe oxides from their contacts.

    Hi, thanks for your input. Unfortunatly I have already tried all of that. I have tried two sets of speakers as well as speaker cable and interconnects but still the same issue from right channel. Even happens with the inbuilt tuner on the receiver.
    the only real 'manual' type switches on the unit are the volume and balance controls etc. All of which appear to be functioning ok as there is no crackling or anything on any dials and it doesn't actually cut out when altering anything.
    I'm guessing it's the amp/output stage somewhere but don't know if I'm on the right track.

    You could have mentioned what you tried up front.

    Every pushbutton on the front panel has Normally Open and Normally Closed contacts.

    Tape Monitor or any switch that is normally untouched is notorious for getting glommed up. A spritz of tuner cleaner or vigorous and repetitive toggling can sometimes help. Prove or disprove any switch's involvement in the problem by just lightly touching each one next time it arises.

Hi,
Looks like your volume control switch is not working on the left side, you can check it by tapping the knob on the volume control and sound will come out on left side.
The only way to get the sound again is to replace the volume control or pull out the volume control and open it up to clean the contacts in it.

Hope that helps you out!
Thanks for using Fixya!

Crackling sound from right speaker only


I'm not familiar with that model but I am familiar with the problem. If your unit has a volume knob or a balance control which is a potentiometer you need to clean them. Go to www.mcmelectronics.com where you can find spray cleaner. I like to use blue shower as it works well and will not hurt any components. When you get the cleaner unplug your unit and locate the volume control and any others which have a rotating knob. Usually near the top is a small hole which you can spray the cleaner in. Rotate the control and follow through several times. Try the unit and it should be ok. If it isn't you will have to replace the controls as the resistance material has worn off and they cannot be repaired. Let me know how you make out or if you need anymore help.

i would check your sond devices. go to the speaker icon at the bottom on the right side of the windows toolbar and right click. open playback devices and adjust the volume from there.

ATP3 intermittency problem


I've had intermittent speaker problems with these models and it was caused by slight abuse, ( stress on the speaker jacks at the main board located in the main subwoofer cabinet). The problem can lead you to believe its the speakers or the wires but in my case it was a loose solder joint on the main board in the subwoofer. I had to take the subwoofer apart and carefully re-solder the connections of the speaker jacks. I've had no problems since. I've also been a little more careful not to push the jack side of the connection against the wall, kicking with my feet etc..
