Could you read specificat ion thus as below.Performance

Output Power 50 watts into 8Ω 70 watts into 4ΩMusic Power 77 watts into 8Ω ;105 watts into 4ΩFrequency response -1dB at 14Hz and 70kHz (at 1W- see Fig.1)Input sensit ivity 0.875V for 50Ω into 8ΩHarmonic distort ion <.05% from 20Hz to 20kHz; typically <.003%Signal-to-Noise Rat io -114dB unweighted (22Hz to 22kHz); -119dBA-weighted, both with respect to 50W into 8ΩDamping factor >140dB at 100Hz & 1kHz, with respect to 8Ω and withoutPTC thermistorProtect ion fuses plus “Polyswitch” PTC thermistor .
