You are looking at specs for the foreign model that uses a 240v line. This amp uses way less wattage than a microwave. I run this amp on the same circuit thru my Panamax as my tv, DVD player, wifi, DIRECTV, 851n, 851e, and this amp in a large open room with 12ft plus ceilings. The Panamax has never indicated that I had any voltage draw issuesÂ
