Pioneer M-EV51 surround problem.

Most problems are menu settings, because surround modes can be complex and confusing. Verify what surround input type you are using. FM tuner will not play center spkr unless put into a simulate or expand stereo mode. Do other surround speakers work other than normal L/R stereo mode? You can try redoing your auto surround setup (MCACC) or going to the manual speaker setup and verifying speaker is turned on in menu system. Rechech you listening mode setups at Pages 33,38,39 in your manual. Try another speaker and wiring on center output. Try Different surround inputs, some manufactuers have had problems with their DTS and HDMI boards. Otherwise take to repair.

go to audio set up and configure the system for 5.1 or higher sound output.then only all the speakers ll work

wondering if input levels are too high on some channels causing safety limits to shut it out..check level outputs on eguipment.

check the rear spkr first using multitester

Hi there,

These are the general wiring harness colors and their respective connections:

+12 Volt Battery Wire YELLOW (i.e. constand power for memory)
+12 Volt Ignition Wire RED (i.e. power only when key is ON)
Power Antenna / Amp BLUE/white stripe
Chassis (NEG) Ground BLACK

Front Left Spkr (+) WHITE
Front Left Spkr (-) WHITE/black stripe

Front Right Spkr (+) GREY
Front Right Spkr (-) GREY/black stripe

Rear Left Spkr (+) GREEN
Rear Left Spkr (-) GREEN/black stripe

Rear Right Spkr (+) PURPLE
Rear Right Spkr (-) PURPLE/black stripe


Cheers,

The rear speaker decoding has to be enabled for them to function, regardless of the media. Enter the speaker setup menu and choose "yes" for the rear surround speaker decoding.

I had this problem too. Finally, after using the MCACC setup and making sure all the speakers worked, I found I had to set the source to FM, TV or whatever from the remote control and set the mode to advanced surround sound using the front panal button on the upper right. Had to fool with them a lot. Good luck.

first check if the speakers are working at all put them in other channels and see what happens

Hey Tad, I have the same problem and perhaps a solution. I just moved to the other SW "pre-out" and it seems to be working..the green light is on . Whatever works i guess.
