Question about Pioneer Audio Players & Recorders

Pioneer VSX-521 continues to overheat

Amp has been working for about a year with no problems, I moved and first just hooked up Front L-R, Center and Sub.speakers. Worked great for about two weeks until I hooked up the rear speakers. After doing setup it worked for about 30min and shut off. I checked to see if a speaker wire was crossed. but still shut off. I finally unhooked everything and it came on but said it is "overheat" and then shut off. Is it fried or is there something I can do?

It's an internal breakdown ...tech service only.

SOURCE: pioneer vsx-519 no sound from center and surround

Make sure that the sound field/programme you have selected is dolby digital not stereo.(On the amp)
You also need to check on the display that is says DIGITAL not ANOLOUGE, as only a digital input, Optical fibre cable, HDMI, COAX will be a digital signal.
If you are using red and white rca connectors, it is not going to work, as this is an Anolouge signal.

SOURCE: pioneer receiver vsx-d510 sub not working

Rear Surrounds are not supported on this unit, they would be the 6th and 7th channels in a 7.1 rig. I think you mean Surrounds (channels 4 and 5 in a 5.1 rig).

Lets ponder: How is there any relationship between Surrounds and your separately-amplified Subwoofer? I don't see it, unless you inadvertently chose OFF for the Sub definition when you were in the Speaker selection menus adding the Surrounds. Look again.

My pioneer pl-200 doesn't play loud enough through my pioneer vsx-521-k receiver


The PL-200 has no pre amp and your VSX-521 has no phono input. You need an RIAA preamp.

No audio output


THE FIX - to audio problems that persist with the VSX-29TX and others using the AWX7272 DSP board is to replace the ROM on the DSP. My unit started failing on and off after 10 years of use! The intermittent DSP board is an Extremely Common and irritating Problem for this model! The replacement IC,(2) resistors + shipping and handling totaled $49.65 and my unit is finally fixed correctly! Don't believe other posts that you can get away with re-soldering; it will continue to fail again and again! Details of fix are:

Replacement for the old Pioneer ROM located at location IC 9374, should be done with the part PD6381A from Pioneer Electronics. You will also need to move (relocate) the 2 resistors (0 Ohm resistors) located at R9372 and R9371 to locations R9374 and R9373.

This component update applies to DSP boards marked as AWX7433, AWX7272.

This fix is validated (from Pioneer) on the VSX-26TX,VSX-27TX,& VSX-29TX it might also work in the VSX-908, VSX-908RDS and others as long as the same DSP board was used.

Let me caution and stress that surface mount soldering skills ARE REQUIRED to do this update! It also doesn't hurt to have excellent vision and/or an eye loop or microscope to check your work. Original ROM's were subject to timing changes internal to the part as a result of HEAT. This model does get HOT! The program was also modified as a further safeguard to re-occurrence.

I have pioneer receiver Vsx-454 i want to know if this receiver is 5.1 surrounds


Yes. It is 5.1 surround. There are 2 front channels, 1 center channel, and 2 rear channels which comprise the "5" in 5.1 surround. The pre-amp output channel for a sub is the ".5".

This is not a pioneer vsx-454 receiver problem


I would not recomend doing this because the 4 ohm speaker is not enough to offset the 32 ohm speaker and the amp will have problems keeping up with the power consumption of the speakers and will eventully overheat and cause damage! (it will work but not well and not without risk to your amp!)
Please rate this quick response
Thank
You!
