This is a powered PA, no external amps required. It has six channels, with some extra inputs for RCA inputs.
The only flaw I’ve seen with this unit is three EQ slider posts have snapped, but they still move and operate as intended.
The unit is in Delphi but I can bring to the Lafayette area.
Here is the “official” description from Mackie:
The Mackie 406M powered audio mixer delivers 500 real watts into 2 ohms from twin 250W FR Series High Current power amps, switchable as mains or mains plus monitor. The mixing console provides 6 mic/line channels with inserts, input gain controls with level set LED on each channel, active 3-band EQ on each channel, and 2 separate 9-band graphic EQs for mains and monitors.
