Schematics for Sx-240?

Schematics for Sx-240?

2006-03-23 by Joan Martínez

Hello to the group!

I'm new here, in the list. Recently I bought a SX-240 with some problem.
This especially likes to me, because I can jump inside the synth and learn
about how it works while I'm fixing it.

Anyway I think there's more problems inside than I ought to find. I get the
felling that some of the DCOs/Filters/AMP stages are wrong or not properly
adjusted. Before to deal with these problems with the 'try and error method'
I want to ask for some help.

If someone knows where can I find schematics or block diagrams or service
manual I will be happy to know it too.

Thanks!

Joan M.

Hi Joan,

  Kawai will sell the schematics after a non-disclosure form is 
signed. Hopefully they can sell them to you where you live. I just 
bought a dead K11 for next to nothing and paid $35.00 U.S. for the 
Service Manual.(more $ than the synth) I'll probably have the 
service docs before the synth gets here. Good luck with your SX-240. 
Check in with the group if your still having problems maybe we can 
help. Now if only someone had some K11 - Gmega patches out there.....
I'm planning to make up a bunch and I'll post them if I get my K11 
working. It may only be that it sat around for a while and needs a 
new battery....

Hi Narfam!

Thanks for your help. I'll try to contact with kawai distribution in Spain
to try to get the schematics. I think kawai it's placed in Bilbao.

I hope that you could be more lucky with your k11 than me with SX-240. Now I
made a general keyboard contacts cleaning, put a new battery and I tried to
load the original patches from the files directory to the synth.... No
succes!! There's an error message while is starting with loading operation.

More problems the synth gets: In MONO mode all the notes are played in the
same level and well L-R balanced. In POLY-4 and POLY-8 modes several notes
are played with lower volume and   adjusted to the R output channel. I feel
there's at least one of the stages DCO/VCF/VCA thats is broken or not
adjusted. So.... as you can see there's more job to do than only change the
battery  :-(

Anyway, as I wrote before, better luck for you with your fixing operation
;-)
