PROS / It has exceptional connectivity – both wired and wireless.
CONS / It doesn't support HDMI 2.0.
VERDICT / The Yamaha RX-V577 offers plenty of inputs and wireless connectivity, but it won't support the 4K content of the future.
The Yamaha RX-V577 is an AV receiver that can handle all your home theater audio needs. It has everything you need in a home theater receiver today, but tomorrow you might wish for a bit more functionality.
This receiver can't upscale video to higher resolutions like some of the best AV receivers can, but it can pass through 1080p video, so you can connect your 1080p media players and gaming consoles to it and then connect the receiver to your television. It can also pass through 4K video, but only with a frame rate of 30 fps.
That's fine for today's 4K content, because almost all 4K content is at 24 fps. However, in the near future, some 4K content will have a higher frame rate, so you'll need a receiver that supports HDMI 2.0, which will enable it pass through 4K video at higher frame rates. It also lacks support for HDCP 2.2. This is an encryption that will be placed on the 4K content of the future. This could cripple the RX-V577's future functionality.
It can, however, pass through 3D video. These pass-through capabilities are important because you'll want to use a receiver as a hub by connecting all your input devices to it. This simplifies input switching on your television setup.
The RX-V577 can power up to seven speakers and two subwoofers. This is on par with the most speakers supported by any receiver we reviewed. The 7.2 speaker experience gives your movies a cinematic feel.
This receiver does not have built-in Bluetooth, but Yamaha sells a modestly priced Bluetooth adapter that adds that functionality. This gives you the ability to stream music wirelessly to the RX-V577 from any Bluetooth-enabled device.
It does have built-in Wi-Fi capabilities. Apple users can send music to it through AirPlay, and Android users can use DLNA for the same purpose.
It also has a large number inputs and outputs. It features six HDMI inputs, one optical input and four analog audio inputs. The HDMI inputs let you connect modern devices, and the other inputs allow you to connect your older devices.
Yamaha offers phone, email and social media support options. It also supplies a two-year warranty, which is standard for the industry.
The Yamaha RX-V577 is a well-featured AV receiver with plenty of connectivity. However, its lack of support for HDMI 2.0 and HDCP 2.2 is a flaw that could become more inconvenient with time.
