OUR PART # RB-UL4
Sonifex's RB-UL4 is a 1RU rack-mount quad stereo unit for interfacing domestic or semi-professional unbalanced equipment to professional balanced line levels.
All connections are on the rear panel. The eight RCA unbalanced inputs have an impedance of 10kOhm and are routed to eight 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.
