1. Hum is usually the main filter capacitor
2. Audio output filter caps

Check for open or change in capacitance

Re: Pioneer VSX108

You have an amp problem or maybe a short in the output area

Plays only mono when listening to music

I lot could depend on how the music source has been connected to the receiver. If you are using a stereo CD player then you may need to check if it is configured to send audio in stereo mode and not mono. The input source selection for the audio is given in page 26 of the manual.
You can go to the setting menu in Receiver and configure the speakers settings according to which ones you have installed.
Also refer page 25 in the manual to over ride speaker configuration if it is not showing correct.

Major hummimng noise when sub is connected to receiver.

Is the hum in the receiver-attached speakers or the sub?

Self-powered sub?

How is the sub attached - RCA or speaker-level?

Disconnect the input(s) and see if it hums in the absence of an audio source. A bad audio cable shield or unwisely-routed audio cables will allow entrance of unwanted signals from external power sources, magnetic fields, even dimmer-controlled track lights. Sometimes, simply reversing the orientation of the ac power plug can eliminate humming.

If it hums with the sub attached, unplug the sub's power cord. Differences in AC ground potentials will generate hum across linked devices.

I have a pioneer xc-is21v .basically 2000 audio model which has a vcd player and amp with woofer . i get a humming noise in the speaker but not in the headphones pluged in amp.this is a low ?60hz hum...

It may be that your headphones just don't handle that frequency well enough for you to notice it. A hum at this level could be due to earth(grounding) problems caused by a double earth. If you have other devices (tv, laptop, CD player, games console and the like), plugged into your amp try unplugging them one at a time to try and identify the source of this hum. (I get this occurring with hum on my television if I leave my laptop plugged into my audio system - which the TV is also connected to - even if the audio system and laptop are powered off).
If this resolves the problem you may need to insert a ground loop isolator device between your amp and the device that is causing the problem.
Although this one (on sale in the UK from Maplin) is designed for car audio systems I use it on a public address system to eliminate ground loop hum on the stage fold-back amps.

I have a Pioneer VSX-1019AH-k receiver for about 15 months. Recently it has developed a hum. I'ts present on all speakers and all input sources (cable TV, blue ray, tuner, etc.). I haven't made any changes...

Hum on sound is commonly caused by a leaky electrolytic capacitor on the power supply section and or on the output ic. Dry joints is also going to consider on the said parts.

I've advice you to send it to repair shop to isolate the problem or just look for a qualified technician to do the job. This is quite fixable.

Pls rate my help.

Thanks for using fixya.

I have a pioneer elite vsx 36tx receiver that quit working. When I turn it on it just hums. It seems like a power supply but not sure.

I have the same receiver.

Do you mean there is an audible hum from the unit, or that speaker output(s) hum?

Let's figure out what DOES work...

Do you get the audible relay click a few seconds after power up?

Does it tune FM?

Can you get the On Screen Display? Settings all ok?

What preceded this? RSVP.

Pioneer Receiver SX-750: Getting a loud hum through the speakers

The hum you hear from the speakers and from the unit itself originate with 60hz AC power. They may not actually be related. Sometimes a transformer will hum slightly and unnoticeably. That you're getting a loud speaker hum says there is an electrical leak or a grounding issue somewhere.

Do all sources produce the hum or, say, just the phono? How about on headphones? Try rotating the AC plug. In those days they weren't keyed with one large blade as they are now.

Constant Buzz coming from SX-255r

Power source harmonics. Or its power supply regulation. Check also if input line is touching something.

Pioneer vsx 90txv and bose EQ

I wrote this for a different receiver, but if you account for minor differences to your receiver this will work just fine.

There's good news and bad news. The bad news you need a separate amp because a multichannel receiver with Bose 901's attached as recommended for a standard stereo receiver will only sound right in STEREO on stereo analog material. The other speakers around the room are not designed to receive its Active Equalization and if you engage your Tape Monitor you will NOT BE ABLE TO HEAR DIGITAL sources at all. Tape Monitor is for analog stereo material only and on modern AV receivers it disables any digital inputs so you really can't use the Tape Monitor circuit or attached devices for modern digital sources. However, you can still employ the various DSP options to spread 2-channel analog source material around the room. I do.

The good news. I have a setup similar to what you want to do and it works great! With one caveat - My receiver actually has 5.1 analog Outputs so I can drive up to 6 external amplifiers if I want to (I drive 4). IF yours does NOT (*) we have to be creative in extracting the front two channels from your multi-channel receiver. The obvious alternative place would be at one of the few OUTputs on the back, assuming you have one free to use.

* I can't find your exact manual so I have to extrapolate features.

I see on the SR>6003< there are Pre Audio OUTS so I'm betting your receiver does, too.

A separate stereo amp for the 901's was my solution. I run a Carver AV-406 (5-channel amp) for my 901's in Front, 2 Subwoofers and the Rear Surround channel, with the Active EQ between the receiver Front L&R Outputs and the 901's amp channels. My receiver controls everything and just drives the Center and Surround speakers.

You could get by with just a stereo amp for the 901's. A Carver M-200 is a good efficient amplifier that would have you cooking just fine (2x100W). Run it with the Active EQ between the receiver Front L&R Pre-Outputs ** and the 901's amp channels.

** Front Pre Out; (or VCR or Tape Out if you don't have Pre Outs) >>> Bose EQ Amplifer IN, then
Bose EQ Amplier OUT >>> new amplifier IN.

Attach the 901's to the new amp, set its volume to Max and run through your receiver's speaker level setup.

*** If you use a Tape or VCR Out you will NOT be able to SELECT the source you use for the 901 Pre-Outs for listening, or else the 901's will not get any sound sent their way. DO NOT USE the monitor switch for that source.

My onkyo tx-sr705 produces a humming noise out off all the speakers when no audio is played

I found the source of my hum. I have Direct TV HD. I found that going into the menu settings (Direct tv HD Receiver) /Audio/Sound Effects and turning that option off, I was able to rid myself of the annoying hum. The option has something to do with keeping the audio settings from channel to channel, while it is changing you hear dead air except for the hum. Nice and quit now. Love this receiver!
