Product Description
Pro Intercom AD920 Balanced/Unbalanced Interface Adapter
Overview
The AD920 Balanced/Unbalanced Interface provides impedance matching and signal conversion between a balanced intercom circuit and an unbalanced intercom circuit. Both channels become audio and light-signal compatible. Power may come from either intercom circuit or from both simultaneously.
This is particularly useful for production crews wanting to use their unbalanced system with a balanced 'house' system. Each circuit to be used will require its own AD920.
There are no user-operated controls. Connection is via clearly marked 3-pin XLR connectors; 1 female, 1 male.
