The RB-SM2 consists of two independent converters which will produce two fully buffered and balanced mono line outputs from two stereo inputs. All connections are on the rear panel. The XLR-3 inputs are electronically balanced with an impedance of 20k bridging. These can be wired unbalanced to accept an output from domestic equipment.
The XLR-3 line outputs are electronically balanced with an output impedance of under 50 . The outputs can be wired unbalanced by grounding the non-phase signal, allowing you to feed both balanced and unbalanced equipment.
Output gain adjustment using pre-set potentiometers for both converters allows a normalised mono output from domestic stereo equipment. The potentiometers are accessible through the rear panel.
