Description

Sonifex RB-BL4

Dual Stereo Bi-Directional Matching Converter

Broadcasters Warehouse -The RB-BL4 is a dual bidirectional stereo unit for interfacing domestic or semi-pro unbalanced equipment to professional balanced line levels, and vice versa.

The four XLR-3 electronically balanced inputs have an impedance of 20 kΩ bridging and are routed to four unbalanced RCA (phono) outputs with an output impedance of <50 Ω.

The four RCA unbalanced inputs have an impedance of 20 kΩ and are routed to four balanced XLR-3 outputs with an output impedance of <50 Ω. All connections are on the rear panel.

The output gain can be adjusted for left and right channels by using pre-set potentiometers accessible through the rear panel.
