The Product

The RB-SM1 converts a stereo input to a fully buffered and balanced mono line output. The left and right inputs and mono output are presented on the rear panel on XLR connectors. The input is electronically balanced with an impedance of 20kΩ bridging and can be wired unbalanced to accept an output from domestic equipment. The output is electronically balanced with an impedance of <50Ω which also can be wired unbalanced by grounding the non-phase signal, allowing you to feed both balanced and unbalanced equipment. Output gain adjustment using a pre-set potentiometer for the converter allows a normalised mono output from domestic stereo equipment. This potentiometer is accessible through the rear panel.

An optional RB-RK1 rackmount kit is available separately.
