The RB-BL2 is a bi-directional stereo unit for interfacing domestic,
or semi-pro unbalanced equipment to professional balanced line levels, and vice-versa.
All connections are on the rear panel. The two XLR-3 electronically balanced inputs have an impedance
of 20k ohms bridging and are routed to two unbalanced RCA (phono) outputs with an output impedance
of <50 ohms.
The two RCA unbalanced inputs have an impedance of 10k ohms and are routed to two balanced
XLR-3 outputs with an output impedance of <50 ohms.
The output gain can be individually adjusted for left and right channels by using pre-set
potentiometers accessible through the rear panel.
