2/4-Wire Interface
The 19“/1 RU 4-channel 2/4-wire interface IF-2104 converts four partyline channels to transformer balanced audio inputs and outputs (4-wire) on individual XLR-connectors. The 2/4-wire hybrid features automatic nulling. The interface detects the S-CALL and can switch built-in relays to activate paging systems, radio equipment or other external devices.
