1RU 4 port IFB breakout interface
1RU four-port XLR-3 IFB intercom/audio cue break out matrix interface. Each IFB output and program audio/cue audio uses XLR-3 I/O and is transformer balanced. Connections to the matrix use RJ-45. If directly connecting TR-50s, a power supply such as the PK-7 or PS-702 is required.
