Sonifex RedBox Matching Convertors

Sonifex RedBox Matching Convertors

These RedBox stereo matching convertors are for interfacing domestic or semi-professional unbalanced equipment, such as a CD player, to professional balanced line levels and are available with either one or two stereo channels.

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.
