Mv 8000 input does not switch from optical to analog

Are your RCA headphones wired, IR, FM wireless, or do you mean they have RCA/phono plugs?
Whatever the config, you'll need a DAC,or digital-to-analog converter for a start, as the fiber-optic transmits a digital-encoded pulsed signal only, which has to be decoded back to the audio sampled voltages to re-create the original wave-shape.
The DAC must have D/A optic input.

I'm sorry. I have no first hand experience with these units, not to mention, I'm a hardware guy. I can repair it, but I have to look in the owner's manual, just like you, to use it. These are questions you should be able to find in your owner's manual. If not there, check with the Roland website.

go through the menu looking for a "clock" option and set the clock to "internal"

Did you try a new hard drive? It may be faulty. Can you pull the drive and see if the unit will start?

Hey..I have the exact same problem, did you get it resolved? Contact me at... [email protected]

no solution from me but if you want to sell your MV 30 I would love to buy as I have one with a working screen but a non-working floppy drive

You can't. Best way is to set your FX on your track. Hit sampling button, then go to the Resampe tab, hit start, run your track, save sample, load it back up. Not exactly how I woulda set things up, So I make everything dry on the mv and dump into my DAW for FX...Not sure what Roland was thinking with this little gem, but hit up MVNation.com...best site for info on the MV. After I found this site, I threw the manual out. Hope it helps.

Hello,

Yes, from what I understand, it came with a floppy, CD-Rom, and a 40gb hard drive.

I TRIED TO FIND THIS BOARD UNSUCCESSFULLY FROM REGULAR AND ONLINE MUSIC STORES. THROUGH ROLAND SALES REPS, I LEARNED THAT THE PART WAS ON NATIONAL BACKORDER AND SCHEDULED TO BE DISCONTINUED. THIS WAS ALMOST TWO YEARS AGO IN 2007. I HAD LUCK TRYING REPAIR SHOPS THAT SERVICED ROLAND EQUIPMENT AND OWNERS WHO HAD THE CARD INSTALLED ALREADY. TRY CRAIGS LIST, AND MV NATION

GEO (GEO Production and Audio Svs.)

trade it in for an mpc.
