AUDIO: This graph shows that the RX-A2040’s left channel, from Audio 4 input to speaker output with two channels driving 8-ohm loads, reaches 0.1% distortion at 169.7 watts and 1% distortion at 195.9 watts. Into 4 ohms, the left channel reaches 0.1% distortion at 259.8 watts and 1% distortion at 317.1 watts.

Response from the multichannel input to the speaker output measures –0.01 dB at 10 Hz, –0.01 dB at 20 Hz, –0.07 dB at 20 kHz, and –2.81 dB at 50 kHz. THD+N from the Audio 4 input to the speaker output was less than 0.012% 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 –80.68 dB left to right and –80.36 dB right to left. The signal-to-noise ratio with an 8-ohm load from 10 Hz to 24 kHz with “A” weighting was –101.56 dBrA.

From the Dolby Digital input to the loudspeaker output, the left channel measures +0.01dB at 20 Hz and –0.34 dB at 20 kHz. The center channel measures +0.01 dB at 20 Hz and –0.34 dB at 20 kHz, and the left surround channel measures +0.01 dB at 20 Hz and –0.36 dB at 20 kHz. From the Dolby Digital input to the line-level output, the LFE channel is +0.17 dB at 20 Hz when referenced to the level at 40 Hz and reaches the upper 3-dB down point at 94 Hz and the upper 6-dB down point at 116 Hz.—Mark J.

VIDEO: The Yamaha passed all of our standard video tests. It was a fraction of a second later in locking onto 2:2 than the very best AVRs we’ve seen, but this was minor enough to not affect its rating.—TJN
