Issue with Pioneer VSX-32? - Blu-ray Forum

mostlyharmless · 06-05-2013, 08:23 AM

I'm wondering if my receiver has somehow managed to fry its DSP chip? I currently have a VSX-32 which has the front 3 channels run into an adcom 6000 amp, the middle and rear channels are running off of the VSX.

Here's the problem, a few days ago, the mid and rear channels quit working. I thought the sound suddenly sounded very anemic, and quickly realized I had no sound coming from the back 4 speakers. At first I thought perhaps the amplifier had fried, seeing as I had sound from the front 3 separately amped speakers. Then I started messing with some of the sound settings. Unfortunately, all settings except extended stereo result in dead back and mid channels, but when I set it to extended stereo, suddenly I have sound coming out of all 7 speakers.

Can anyone take a guess as to what happened to my beloved AVR? Is this something worth getting fixed? Or should I just start looking for a replacement?

I suggest slowing running a series of tests, starting with the AVR's internal test tones and then progressing through stereo and multichannel sources on a calibration disc to determine what plays properly. First, reset the AVR to factory defaults. Then, begin with a Direct setting on the AVR to remove digital signal processing from the equation. If you get proper output that way, then see what happens when applying various DSPs such as PLIIx, DTS Neo:6, and others such as all channel stereo.

Thanks for the heads up. I'll start fiddling with it a bit now and post up what I find shortly..

*EDIT*

OMG Thank you so very much! I don't know what resetting did, but it worked! I now have all modes available to me again! I Owe you a beer or 12 Bislander! I had done done the full run through earlier of all of the various modes and all I was getting was the front channels, I'm really not sure what I could have done that messed everything up, but the reset worked like a charm. I'm going to have to remember that little move. I was sadly looking at AVRs last night and frowning over what I figured was the inevitable hit to my wallet!

Glad that helped. Resetting seems to work wonders for those kinds of off-the-wall problems.
