Hmm,
I have doubts:
7 X 225 Watts continuous at 4 Ohm, that adds up to 1575 Watts.
Now looking at the heat sinking this must be a class AB amplifier.
The specs published on the Outlaw website say that the MAXIMUM DC input power = 1440 Watts, so we safely can assume that a 1,5 KVA transformer is used.
The real watts that such a device can draw from the net depends on the power factor 1500 KVA X cosinus phi ). So that is probably why the specs say 1440 Watts. It simply is the maximum continuous load that the power transformer can handle. Any electronics engineer will tell you it would be extremely unwise to design a power supply with 0 % safety margins for continuous operation at its rated specs. A reserve of at least 10% (preferable a bit more) would be wise.
Now, if the power supply is designed on the edge without any safety reserve, even then those 1440 watts will never be available as continuous output power. Class AB amplifiers burn about 25% of those watts in heat, that is why serious (non switched) amps always need plenty of heat sinking (and this Outlaw fortunately has plenty).
0.75 X 1440 Watts divided by 7 boils down to less than 160 Watts per channel, no matter what the load impedance might be. No way that this Outlaw amplifier pushes out 7 X 225 Watts continuously. Let's hope that it shuts down or blows a fuse else it simply burns up it power transformer.
Now at 8 Ohm the power rating is 7 X 140 W= 980 Watts in total. Would it be a coincidence that 980 Watts corresponds with 0.75 (AB efficiency) X 1440 X 0.9 (the minimum power supply safety reserve).
I don't say that this is not a good sounding amplifier. An undersized power supply doesn't affect the sound quality as long as the amp isn't pushed too hard.
But shame on you Outlaw, your specs should say 7 X 140 Watts at 8 Ohm only.
Could it be that this device originally was designed with a 2000 VA transformer that later was replaced with a 1500 VA model to save 200$... 250$ in the retail price?
Or is it designed as a pure 8 Ohm amplifier?
Whatever the answer, I don't like neither of them.
