The connectors Spare 1 and 2, provide access to the two rows of eight pushbuttons below
the Bypass switch control button row. These buttons can be used to control any equipment
requiring a closing contact. However in systems with multi level audio, or if the panel is to
provide control of more than one system, these buttons are used for that purpose and are
therefore not available externally.
Connecting the Automation port to the MIP (manual intervention panel) port on a Pro-Bel
automation controller provides the operator with direct access to key automation controls,
permitting the ‘on air’ schedule to be effected without the need to access an automation edit
terminal.
