Sequential prophet 5 Technical Manual page 2

About This Manual and Servicing The Prophet
The Prophet is a sophisticated instrument, and SEQUENTIAL CIRCUITS INC. issues its technical
manual for use by qualified technicians only.
Of course the manual will also be read by Prophet owners and others interested in synthesizer design.
And we realize it will also be used by some to modify their instruments.
While we support this innovative attitude in spirit, we cannot support it financially. Modifications or
unauthorized service void the Prophet's warranty. They also invariably extend service time (thus,
cost) if factory repair is required.
Familiarize yourself thoroughly with this manual before attempting any work on the Prophet. This
will at least help you judge whether you should be working on it at all. If in doubt please contact our
Service Department.
The manual is organized as follows:
SECTION 1 describes the Prophet's physical organization and procedure for its complete disassembly.
SECTION 2 covers principles of the system (hardware and software) design.
SECTION 3 contains complete schematics and pictorials identifying all components.
SECTION 4 explains how to tune and adjust the Prophet for optimum musicality.
SECTION S offers aid in identifying and correcting malfunctions.
SECTION 6 is included for you to order replacement parts from SCI.
