Sonifex RB-BL4 Dual Stereo Bi-Directional Matching Converter (1U)
A dual bi-directional stereo unit, the RB-BL4 connects an unbalanced home or semi-pro equipment to balanced professional line levels and the other way around. Four unbalanced RCA (phono) outputs with an output impedance of less than 50Ω are connected to the four electronically balanced XLR-3 inputs, which have an impedance of 20kΩ bridging. Four balanced XLR-3 outputs with an output impedance of less than 50Ω are connected to the four unbalanced RCA inputs, each of which has an impedance of 20kΩ. The rear panel houses all of the connectors.
The output gain can be adjusted for left and right channels by using pre-set potentiometers accessible through the rear panel.
