Alto mac 2.3,  yet another qsc rmx copy? 
Transformer has 4 x 54Volt output / secondary windings.  Bus voltage 83Volts.. 
Claimed output power:
2x285W/8ohm rms
2x510W/4ohm rms
1x1000W/8ohm rms
1x2200W/4ohm (EIAJ)

rms ratings are pretty much ok, according to supply voltage.

Should I take my dummyload and make some real tests? :D 

Power amp board is quite neat anyway, having 8 power bjt's / channel.
