Question about Audio Players & Recorders

1 Answer

Old pioneer vsx 3800 receiver works great except for the volume knob being stiff. At the same time the volume is touchy, if that makes any sense. Also, the remote control will increase volume but not decrease it. A new remote has the same result. The system does sound good, but using it for my TV audio makes it a pain when I can't lower the volume during loud comericals and such. Is there an easy fix for this? Or is it worth fixing?

This is a common problem where the potentiometers in electronic equipment gets guncked up over time. If you are confident with your DIY skills, you need unplug the receiver and remove the cover. This may or may not be the tricky part. Some receivers are very densely populated and it is hard to get to the components. That being said, you need to find back of the volume potentiometer and spray some contact cleaner inside of it. Then work the pot back and forth several times and that should free it up. This should also take care of the touchiness. You can find contact cleaner at Radioshack or maybe even Walmart.

How to make a Pioneer vsx-816k/s last longer


I really don't recommend this product to anyone, or any newer pioneer products for that matter (except the elite line). This model has the "hybrid" design, which is a very flawed design. At first the speakers will start cutting in and out, and then some of them wont work at all, and then the receiver will flash "overload" and the receiver will go into a permanent protection, all because the receiver cant handle the resistance of the speakers(doesn't matter what speaker it is). Once in protect mode, press ENTER+ ADVANCED SURROUND and it will tell you what the problem is causing it to stay in protect mode. In order to keep this from happening, use external amps. Pioneer wants around 500 dollars to fix it if its out of warranty, it will cost at least 50 to fix it yourself, in most cases it will cost 150 to fix it yourself (most cases all 3 power modules will go out, or as pioneer calls them, power packs). If you have an older vsx model (50s-80s) then it is usually worth fixing. If your having problems with pioneer vsx 3600, 3700s, 3800, or 3900s, send me an email at Joshadk@embarqmail.com and i will help you the best i can

I have a pioneer vsx-d704s reciever and when it is at a very low to 0 volume i get a low level scratching only on the left side. im not sure if it goes away when i turn it up or not but i dont think so


The volume knob is dirty. Behind the face of receiver the "pot", (as they are called) needs sprayed with contact cleaner. I use CRC QD contact cleaner. If the volume is a slider your can use the straw type devise for pin point spraying in the slider slot with receiver off and unplugged. After spraying work the slider back and forth to distribute the cleaner inside. If you have to remove the cover for a rotary "pot"spray while working the dial. Hope that helps..

I've got a vsx-920-k Pioneer receiver with s-11 Pioneer speakers and a s-21w Pioneer subwoofer. All of a sudden my sub stopped working and it seems like it's stuck in standby mode (blue light...


The manual is here...

http://www.pioneerprodj.eu/eur/products/42/99/S-21W/media.html

Flashing Blue is not defined in the manual.

Have you tried changing the Auto Standby switch to ON?

You can prove if the sub amp will respond to a known good input by TURNING ITS VOLUME DOWN tp start and just feeding it ANY RCA output from the receiver while playing, say, FM (to keep it simple). That way you would known in which direction the problem actually lies (internal or external).

Power sub woofer is not working on my pioneer vsx-81txv everything is working all the speakers except the power sub connection at the back all i can hear is the hissing sound when i try to connect the sub...


Hissing? How loud? A sub isn't even capable of making high frequency sounds at normal volumes.

The Pioneer manual would tell you how to enable and test the subwoofer output.
Page 17 and the MACCV procedures on Page 33 (auto) or 43 (manual)

Why does my pioneer vsx-d557 automatically go into MUTING WHEN I turn it on?


Maybe you have MUTING selected. Turn the volume knob up or toggle the Mute control on the remote.

If it defaults to muting on power up find the manual and search it for a default volume setting.

Pioneer VSX-815-K receiver with sub in standby


Have you looked in the manual?

No sound from subwoofer. • Make sure the subwoofer is switched on.
• If the subwoofer has a volume knob, make sure it’s turned up.
• The Dolby Digital or DTS source you are listening to may not have an LFE channel.
• Switch the subwoofer setting in Speaker Setting on page 40 to YES or PLUS.
• Switch the LFE Attenuator Setup on page 61 to LFEATT 0 or LFEATT 10.

Why do the volume numbers on old receivers start


This type of calibartion is known as a logarithmic scale.
The numbers refer to decibels below the maximum output of the amplifier section of the reciever, or decibels of attenuation (making smaller/quieter).

Without going through logarithim theorey, the logarithim (base 10) of 1 is 0. So if 1 is the maximum output of the amp, as you turn the knob down from maximum you are adding more and more attentuation to the output (relative to maximum) and so the loudness of what you hear goes down, even though the number on the scale is going up !

Most peolpe associate decibels with sound levels, but anything can be measured in decibels, so long as there is soemthing to reference it against.

Volume problem with VSX-D409


Had the same problem. I had to replace the volume contol. It was inside the receiver behind the knob. It has a part# on it. Mine was part# AWX7386 (control assembly) from Pioneer.com. If you can figure out how to open the case than you can change this piece. Good luck
