The Sonifex 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 of the unit. The XLR-3 inputs are electronically balanced with an impedance of 20kohm 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 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.
