Sonifex RB-SM2 | Dual Stereo to Mono Converter

The RB-SM2 is a dual version of the RB-SM1, consisting 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 20kΩ bridging. These can be wired unbalanced to accept an output from domestic equipment.

Product Features

• Neutrik XLR connectors.
• Balanced audio but can be wired unbalanced.
• Electronically balanced <50Ω outputs.
• Output gain adjustment.

Typical Applications

To supply cue in broadcast environments, to make a mono feed for AM transmission, or to feed a mono PA system.
