http://www.eu.onkyo.com/en/products/tx-nr3030-117903.html The following is Onkyo TX-NR3030: Power Output All Channels 185 W/Ch (6 Ω, 1 kHz, 1% THD, 1 Channel Driven, IEC) 230 W/Ch (6 Ω, 1 kHz, 1 Channel Driven, JEITA) Dynamic Power 300 W (3 Ω, Front) 250 W (4 Ω, Front) 150 W (8 Ω, Front) ============================== 1) exactly WHAT is the output wattage per channel? What do they mean by 185W at 1% THD 1 chnl. driven, IEC and yet 230W / ch. with some JEITA? 2) what is mean by dynamic power 300W Front at 3 Ohm? Are they giving 300W per speaker at Left , Center and Right? that would mean 3 x 300W at 3 Ohm 3) the power consumption of this receiver is 1105W. But since ea. chnl. 185W, and this is a 11 chnl. unit, should the power consumption be 185W x 11 = 2035W 4) IF the center speaker is 600W, but left / right speaker is 200W say, what wattage would this receiver sends out to the center, left, and right?
