Power saving states are measured with speakers attached but not worked.
The recovery time from stand by /suspend/off mode to on mode is 3 seconds maximun.
1.2A (max) at 90VAC input and full load ,
0.6A (max) at 264 VAC input and full load.
30A(0-peak)@ 110Vac ,50A(0-peak) @ 220Vac
(measured when switched off for at least 10 mins.)
