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

Hi, I am new to this site and am going through the reviews so that I can select a good AV Receiver.

My question is about the 'Test Bench' scores. Is there a page explaining how to read/interpret these scores?

I believe this model is rated at 90 wpc x2 channels driven. What is the 149.7 watts on this page? Also, does the output drop drastically to 38 and 32 watts respectively when 5 or 7 channels are driven?

How do these numbers relate to the total power consumption of 440 in this model's specs?

I am looking for a receiver within $1000 with good power (not dropping so drastically when all channels are driven). I have seen models with 110 wpc in their specs but their total power consumption is only 220 watts. So, will the output drop to 40 watts when 5 channels are driven?

Based on announced specs, will the performance of the new RX-V777BT be close to this 775 reviewed? The reason I have been looking at Yamaha models more is because their reliability rating is highest on various forums, compared to other brands.

Thanks.
Satyaa
