From ATI-Audio, the MM100 Match Maker interface solves the inherent noise problem associated with balanced to unbalanced signal flow. The MM100 features balanced L/R XLR input and output connections and unbalanced L/R RCA phono inputs and outputs.
The interface allows signal flow from professional to consumer audio sources, and the reverse, while providing adequate level matching and eliminating noise caused by unmatched impedances. The MM100 provides ground isolation on output, eliminating noise caused by radio frequencies. An internal jumper can be set to provide dual line, simultaneous input or output. This allows the interface to be used as a 2 channel distribution amplifier, or stereo to mono summing amplifier.
