Comments about Atlas Sound AA120 120 Watt 6-Channel Mixer Amplifier:
Worked pretty well for 16 months of PA use in our venue. Not a heck of a lot of power, but it got the job done for background music and speech using corded and wireless mics. Then, without warning, it went kaput. No power to amp, blown out. Tech said he had never seen it before from this model. Power is going to aux power (wireless mic gets powered through this), but no power to the amp (light doesn't come on). [*] In my opinion, you're gambling with this one.
