您搞混了~電阻跟阻抗是不一樣的~阻抗代表施力端跟負載的一種關係
有時候並不直接等於電阻的能量損耗
接下來看規格:(出自音悅)
Burson HA-160
規格
輸入阻抗: 36.5 KOhms
頻率響應: ± 1 dB 0 - 20Khz
訊噪比: 110dB
總諧波失真: <0.12% at 150mW , 0.06% at 100mW
聲道分離度: <54dB
輸出電源: 250mW (less than 1% distortion)
輸出阻抗: phones out 5.6 Ohms
功率消耗: >25W, 內部穩定電源
GRAHAM SLEE NOVO
規格
輸入阻抗: greater than 39 kilo Ohms
輸出: 150mW rms into 32 Ohms, 40mW rms into 600 Ohms (both channels fully driven - 0.05% THD)
建議輸入範圍: 200mV - 1V rms (2.8V p-p)
頻率響應(worst case): Flat: 43Hz to 16kHz (-1dB), 22Hz to 30kHz (-3dB) (volume control at 3 o'clock position)
Hum & Noise: -80dB CCIR Q-pk 20Hz-20kHz (into 30 Ohms)
Distortion (THD+Noise): 0.02% at 1 kHz into 30 Ohms, and 12 o'clock volume control position
喔~我說錯了~應該是高達數"十"K歐姆~不就難推到爆爆
事實剛好相反~好推到爆爆
