HT Labs Measures: Yamaha RX-V2700 A/V Receiver

Five channels driven continuously into
8-ohm loads:
0.1 percent distortion at 63.8 watts
1 percent distortion at 70.9 watts

Seven channels driven continuously into
8-ohm loads:
0.1 percent distortion at 47.9 watts
1 percent distortion at 62.6 watts

Analog frequency response in Pure Direct mode:
–0.97 dB at 10 Hz; –0.28 dB at 20 Hz
–0.00 dB at 20 kHz; –0.13 dB at 50 kHz

Analog frequency response with signal processing:
–2.20 dB at 10 Hz; –0.65 dB at 20 Hz
+0.11 dB at 20 kHz; –25.10 dB at 50 kHz

This graph shows that the RX-V2700's left channel, from CD input to speaker output with two channels driving 8-ohm loads, reaches 0.1 percent distortion at 171.4 watts and 1 percent distortion at 199.3 watts. Into 4 ohms, the amplifier reaches 0.1 percent distortion at 312.8 watts and 1 percent distortion at 354.4 watts.

Response from the multichannel input to the speaker output measures –0.97 dB at 10 Hz, –0.29 dB at 20 Hz, +0.01 dB at 20 kHz, and –0.13 dB at 50 kHz. THD+N from the CD input to the speaker output was less than 0.008 percent 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 –88.94 dB left to right and –86.91 dB right to left. The signal-to-noise ratio with 2.83 volts driving an 8-ohm load from 10 Hz to 24 kHz with "A" weighting was –103.06 dBrA.

From the Dolby Digital input to the loudspeaker output, the left channel measures –0.22 dB at 20 Hz and –0.03 dB at 20 kHz. The center channel measures –0.03 dB at 20 Hz and +0.04 dB at 20 kHz, and the left surround channel measures –0.03 dB at 20 Hz and –0.06 dB at 20 kHz. From the Dolby Digital input to the line-level output, the LFE channel is +0.09 dB at 20 Hz when referenced to the level at 40 Hz and reaches the upper 3-dB down point at 115 Hz and the upper 6-dB down point at 118 Hz.—MJP
