ข้อมูลเครื่อง :
110 watts per channel minimum continuous power (both channels operating) at 16 ohms from 20Hz to 20kHz with less than .4% total harmonic distortion (typically below .005% at 1 watt) Approximate actual power available per channel at "clipping" (both ch. op., 1kHz): 115 Watts. (Note that the actual power output is dependent upon both line voltage and "condition" ie: if power line has high distortion, maximum power will be affected adversely, although from a listening standpoint this is not very critical.)
