Emu XL-7 & MP-7 User's Group

Ah great, I got that buzzing in my headphones last night for the very 
first time.  Weird, as I hadn't moved the Xl-7 since the last time I used 
it.  I remembered about tightening the case screws but they were fine, as 
were all the circuit board screws too.  Anything else I can check, this is 
damn annoying! :)

I just got my mp-7 back from the shop, the headphone buzz is a 
covered repair. But be careful of Advanced Musical Electronics in 
L.A., it took them over 2 weeks to get it back to me (I had to ship 
it).

Does anyone have the gooseneck lamp? any opinions?

thanks!

Any idea of what has been fixed? If anything...

Aaron Eppolito admitted it was a grounding problem from the front pannel
when the unit was opened and closed back again. Thightening 
some screws did reduce the problem on mine, though it still hums a
little bit.

Any idea to improve the grounding between the two chassis pieces?
Wiring the one to the other? Or would using copper screws help?

What this country needs is a good five-cent microcomputer.

I also got this problem from out of the blue....opened up unit, took out 
rom's and replaced, made sure the surface of the base and cover lined up 
perfectly and tigtened down the screws quite tightly...whatever 
magic...buzz gone...I also made sure the power supply wires were tucked out 
of the way as they can kind of get pushed down toward the circuit 
boards...whatever combo did what, it does not buzz in the phones or 
anywhere...good luck

Just opened my Korg Wavestation EX this afternoon (had to replace the
LCD backlight). I could'nt believe how complex and well built this 
unit is compared to the XL-7. It took me several hours to get the job 
done actually.

It's heavy, shielded, it has copper inserts on several places so the
casing is grounded ok, the paint has been painstakingly taken off around
all the mounting holes... Wow.

And it's *dead* quiet, as it's always been.

My Electribe EA-1 also had a lot of copper inside (but the case was
plastic). E-MU could use some. :(

Just to show all is not lost, I just  finally got around to popping
the TechnoSynth Construction Yard and a custom Flash ROM in my  MP-7. 
No Buzz. I did pay close attention to making sure both sides were clean
and the screws were snug.

No, I didn't get a detailed repair receipt (of course!), but the USB 
port was loose also (that was not a covered repair)

Is the buzz only coming out the headphone jack? It seems like it 
would also come out the main L/R as well. If this is the case, we may 
be dealing with another problem. ???

Hi,

the buzzing in my headphone is one of my secret instruments, could it be
generally if layers are 
too loud that they could make that cruuups and craaaps, it happens sometimes
I don´t know 
why, perhaps my mixer or my boxes, don´t know,
Christoph
