JK Audio shows Four IFB unit at Infocomm

June 23, 2006

JK Audio has introduced the Four IFB, a four position analog telephone line interface that provides flexible listen-only IFB for television field production use. Each IFB output and the monitor input/output jacks may be separately connected to one of the four analog phone lines.

All channels feature status LEDs along with individual level and line selector controls. A telephone handset is also provided to permit communication with the monitor phone line.

Designed for use in real world weather conditions, all controls and components of the IFB Four are resistant to dust and moisture. A hinged cover protects the unit's selector switches, add/drop buttons and DTMF keypad. The internal power supply features automatic switchover to a 9V battery.
