Yamaha RX-V775WA AV Receiver Test Bench
Test Bench
Audio: The graph shows the RX-V775WA’s left channel, from Audio1 input to speaker output with two channels driving 8-ohm loads. Measurements for THD+noise, crosstalk, signal-to-noise ratio, and analog/digital frequency response were all within expected performance parameters.
0.1% THD | 1.0% THD | |
2 Channels Continuously Driven, 8 ohm loads | 122.8 watts | 147.5 watts |
2 Channels Continuously Driven, 4 ohm loads | 149.7 watts | 181.9 watts |
5 Channels Continuously Driven, 8 ohm loads | 38.2 watts | 55.2 watts |
7 Channels Continuously Driven, 8 ohm loads | 32.2 watts | 41.3 watts |
Video: The Yamaha failed our standard 2:2 HD and 3:2 HD video processing tests with excessive moire (the 2:2 HD failure is not unusual among the sets we’ve tested, but most sets pass 3:2 HD). While this inevitably reduces its video performance score, viewing a wide range of normal 1080i program material over cable revealed no significant visible artifacts.—TJN
