JK Audio Four IFB - 4 Position Analog Telephone Line Interface

The Four IFB from JK Audio is a four analog telephone line interface. Each of the four lines can be separately connected via a rotary selector to one of four line-level balanced outputs, for listen only IFB. Designed for television field production use, the unit is built for real world environments and weather conditions, with all controls and components dust and moisture resistant.

In addition to the four line outps, the Four IFB is equipped with one balanced XLR line level monitor input and one balanced XLR monitor output. The level of each of the six XLR jacks can be adjusted individually using the independent volume controls. The individual on-hook/off-hook function for each phone line is controlled by Monitor Add and Drop switches. A telephone handset may also be connected for communication with the Monitor phone line.
