This is a quick, easy and cheap solution to “pump” music into six rooms from one system. The GFS-6 allows up to six pairs of speakers to be connected to a pair of speaker outs from the amplifier. If you plan to drive two or more pairs of speakers, the “Protection” button (for its Minimum Impedance Protection circuitry) should be used.
Cosmetically, unit looks good. Some scuff marks here and there but nothing major. A small tiny rubber stopper is missing on the right side panel. Previous owner had some of the buttons labelled which you can remove and put on new ones if need be. We don’t have the original box but will securely pack this for safe shipping.
