Yamaha DX7s

In response to feedback from a number of people, I've expanded the sections I created on the Yamaha DX7s synthesizer. I'll continue to add information on this classic FM synthesizer, as time allows. To date, I've produced specific pages covering the following:

• How to replace the battery in a Yamaha DX7s
• How to restore Yamaha DX7s factory voice and performance data
• How to run the Yamaha DX7s internal diagnostics
• Yamaha DX7s factory internal voices and ROM cartridge voices

I've also added downloadable copies of the following Yamaha DX7s manuals and technical documents to the Music Equipment Manuals page:

• Yamaha DX7s Owner's Manual
• Yamaha DX7s Service Manual
• Yamaha DX7s Parts List
• Yamaha DX7s Circuit Diagram

Please note:
All the manuals available on this website are, as far as I'm aware, out of print and/or for obsolete equipment. If you are the copyright holder of a manual on this website and would like me to remove it, please let me know via the Contact page.
