Well, by deduction:
- it says it uses the PSB-1U which is 9V at 2 Amps (2000 mA)
- it also says it draws 400mA
We can do some ROUGH calcs based purely on the power draw.
So... highest power case is 9V at 2000 mA. Assume a couple of hundred milliamps goes for the electronics, leaving 1800 mA. At an efficiency of (guessing) 50%, that would give 9 x 1.8/2 = 8.1W or 4W each channel peak. Call it 2W RMS per channel.
Same logic and calcs if it is 400mA... gives about 1/4 of a Watt per channel RMS.
Any way you cut it - not much.
