Configuration Options:
The MSI-22 is designed to accommodate many applications. For most applications the factory default
setting is sufficient. For 'special' applications a few jumpers may need to be moved. These Jumpers
determine how the MSI-22 interacts with other Components of the System
Before attempting a Configuration you should review the "BUSS Systems Guide" CI & PA, BUSS
sections
The MSI-22 consists of five Functional Modules:
Two Inputs; Local Microphone/Line Input; PA-BUSS Input
Two Outputs; PA-BUSS Monitor/Communications Output; Speaker Amplifier
CI-BUSS Interface
The Jumper Options determine how these Modules interact and function with each other
