288w @8欧,一直到两欧是翻倍的,到一欧可能就1200w了
刚才那个是我算的,我刚刚找到了一个第三方测的220pro,地雷官方说220pro的所有功率翻倍就是440pro,其实本来应该翻4倍,但是供电不够所以只能翻倍。根据这篇文章说220pro连续是72@8欧,所以440pro的连续功率应该是144@8欧,电阻降一半翻倍。您说的挺对的。
The Devialet Expert 220 Pro amplifier
has complex output protection circuits
that pull power down after around
0.5 seconds. Within that time, tested
with 0.2 sec sine wave bursts, power
measured 144 Watts (34V) into 8 Ohms
and 290 Watts into 4 Ohms. Driven
continuously the figure fell to 72/144
Watts, due to protection, and the case
became hot. Into 6 Ohms, burst power
is 190 Watts, slightly below the 220W
figure quoted but not a consequential
shortfall.
