This graph shows that the T758v3’s left channel, from Audio1 input to speaker output with two channels driving 8-ohm loads, reaches 0.1% distortion at 100.6 watts and 1% distortion at 113.6 watts. Into 4 ohms, the amplifier reaches 0.1% distortion at 139.9 watts and 1% distortion at 164.3 watts.

Response from the multichannel input to the speaker output measures –0.18 dB at 10 Hz, –0.05 dB at 20 Hz, +0.00 dB at 20 kHz, and –2.95 dB at 50 kHz. THD+N from the Audio1 input to the speaker output was less than 0.094% at 1 kHz when driving 2.83 volts into an 8-ohm load. Crosstalk at 1 kHz driving 2.83 volts into an 8-ohm load was –83.27 dB left to right and –84.88 dB right to left. The signal-to-noise ratio with an 8-ohm load from 10 Hz to 24 kHz with “A” weighting was –93.81 dBrA.

From the Dolby Digital input to the loudspeaker output, the left channel measures –0.42 dB at 20 Hz and –0.70 dB at 20 kHz. The center channel measures –0.39 dB at 20 Hz and –0.73 dB at 20 kHz, and the left surround channel measures –0.40 dB at 20 Hz and –0.83 dB at 20 kHz. From the Dolby Digital input to the line-level output, the LFE channel is –0.37 dB at 20 Hz when referenced to the level at 40 Hz and reaches the upper 3-dB down point at 118 Hz and the upper 6-dB down point at 121 Hz.—MJP
