I purchased a supposedly good condition and fully functional Pioneer QX 747 off of eBay. The seller said everything had been tested and the "unit sounds amazing." I got it unboxed and hooked up today only to discover that in all input settings, in all output modes, and with two different sets of speakers hooked up to it, the unit sounds like crap. Specifically the bass sounds fine, but the mid range is VERY muted and there is a loud hiss whenever the unit is on. No matter the volume level, no matter the input used (I have tried AM, FM Mono, FM Stereo, and auxiliary so far), no matter the decoding used (2 channel, CD-4, QS etc...) and no mater what speakers I hook up, there is a very loud hiss, the treble and mid-range is very quiet, and it almost sounds like the left channel is reproducing a "ghost" image of the right channel. I have played tracks where I know there distinct differences between the left and right channels and I am almost not hearing them.
All the switches and pots work smooth and aren't noisy. It just sounds like crap. I know Pioneer wasn't the top of the line (especially the 747 units) but I also always heard that Pioneer units in two channel mode sounded good. This one definitely does not sound good.
What should I check out before I start harassing the seller for my money back or start calling around to find a repair shop?
Thanks.
