General:Speaker selector from Adcom and one of the only safe ways to run multiple speakers on an amplifier.Provides adequate protection, but you still need to be careful not to overtax your amp. Best used with multi-zone casual listening.Brand Background:ADCOM started in the 70s. Our first offering wasn’t amplifiers but phono cartridges. They were no ordinary cartridges; however, they were extraordinarily musical "moving coil" designs that extracted a lot of information from a record groove. These products were so successful that other companies asked us to begin making cartridges for them, too! And so, we became a manufacturer!Early Electronics... ADCOM's first electronic product, the groundbreaking GFA-1 power amplifier, appeared in December 1979. It was substantially more powerful than most of its competition at 200 watts per channel and was one of the first "high current" designs available. . Again, it was an affordable and standout performer. Critical response was phenomenal and the GFA-1 became the "hot ticket" amplifier of its day, as did the successor GFA-1A.Ownership:Single OwnerConnections:Bare Wire TerminalsCosmetic Condition:7/10 = Good.
