各位師兄, 請問damping factor 有冇條數可計出來呢? 因為個 spec 矛寫

Output power (both channel drive)
CD->SP OUT 80W+80W (8 ohms, 20Hz - 20kHz, THD 0.07%)
160W+160W (4 ohms, 1kHz, THD 0.7%)
THD 0.01% (Output-power-3dB o'clock, 1kHz, 8ohms)
Speaker output terminal Speaker AorB: 4ohms - 16ohms
Speaker A+B: 8ohm-16ohm
Bi-wiring load: 4ohms - 16ohms
<Preamplifier part>
Equalizer amplifier output Rec out:150mV
Input sensitivity/impedance Phono MM: 2.5mV/47kohm
Phono MC: 0.2mV/100 ohms
