Yamaha Aventage RX-A4A AV Receiver


The A4A delivers realistic sound and video that transports you out of your home and into your favorite movie.
Whether you’re watching, listening or gaming, you’ll feel completely immersed.

With Surround:AI™ technology that instantaneously analyses scenes by focusing on distinct sound elements such as dialogue, background music, ambient sounds and sound effects, and automatically optimizes the surround effect in real time.

For those without in-ceiling or upward firing speakers in their system, Dolby Atmos with Height Virtualization Technology simulates the Atmos experience with forward facing-drivers. Configure up to five speakers to replicate the effect of two in-ceiling speakers, or utilize all seven channels to simulate the powerful effect of four overhead speakers.

Feel every dimension in Dolby Atmos. Enjoy a 5.1 surround speaker system and two additional overhead speakers or two Dolby Atmos elevation speakers, delivering dramatic overhead effects for truly enveloping audio – including Dolby Surround upmixer for legacy content.

Compatible with wireless rear speakers, combine this AV receiver with the MusicCast 50 or MusicCast 20 wireless streaming speaker and enjoy the amazing convenience of creating a home theatre with wireless surround sound.
What’s more, you get stunningly realistic sound with a clean, clutter-free setup.

Easily turn your current living room into a special entertainment environment where you can fully enjoy movies and music.

Once you apply the update you’ll be able to pass a 4K/120 (up to 24Gbps) or a 8K/60 signal (up to 40Gbps) through the AVR.  On top of this, there is now support for HDR10+ and more.

If you are running a 4K/120 or 8K/60 capable device with correctly spec’d HDMI cabling and a display that supports the 4K/120+8K/60 formats, you will need to make a change in the AVR settings in order to pass the signal through.

Simply navigate through the AVR menu and select ‘Video/HDMI’.
Then choose ‘HDMI Video Format’.
For the HDMI port(s) that the applicable sources are connected to, ensure the video format is changed to ‘8K Mode’.
