Figure 6. RMS Power (-3 dB Pink Noise) and SPL (unweighted, 1 sec averaging) versus volume setting. At about 97 dB, the power consumption is about 250 Wrms, scarcely above Class A operation. The Magic Bus is capable (at a volume setting of 46) of 4307 Wrms into 4.22 Ω, thus the peak power output is 8614 W !!
