Surveillance I/O Connector Functions - Toa SV-200M Instruction Manual

22. SURVEILLANCE I/O CONNECTOR FUNCTIONS

The rear panel Surveillance I/O connector* permits "Speaker Line Reference Impedance Measurement (Initial
Setting)" and "Speaker Line Check" to be enabled and monitored by connected external equipment. Referring
to the pin arrangement and functions, prepare the matching D-sub male connector (screw-lock type) for
connection to the external equipment. (See p. 11 No. 41 SURVEILLANCE I/O connector.)
* Requires installation of the optional SV-200M Surveillance Board.
