The MM7055 power amplifier produces 140 watts of high current output from each of its five channels.  This is "real world” power, too, measured across the full audio bandwidth (20 Hz – 20 kHz) at 8 ohms with 0.08% Total Harmonic Distortion.  Among other attributes, this means the MM7055 is capable of long-term power delivery into low impedance speakers.
