Sonifex RB-LU4 Quad Stereo Balanced to Unbalanced Converter

The RB-LU4 is a 1U rack-mount quad stereo unit for interfacing professional balanced line levels to domestic or semi-pro unbalanced equipment, e.g. for connecting a pro satellite receiver to a consumer hi-fi system. All connections are on the rear panel. The eight balanced XLR-3 inputs have an impedance of 20k Ohm and are routed to eight unbalanced RCA outputs with an output impedance of <50 Ohm.

The output gain can be individually adjusted for left and right channels by using pre-set potentiometers accessible through the rear panel. A LED power indicator on the front panel displays the power supply connection.
