        6. Speaker Configurations

        Yamaha RX-A850's and Yamaha RX-A750's amplifiers can be assigned for different speaker configurations.

        • Dolby Atmos Configurations: The following speaker configurations are supported for Dolby Atmos:
        • Yamaha RX-A850: 5.2.2 with internal amplifier.
        • Yamaha RX-A750: Not supported.
        • Configurations without height channels: There are also other speaker configurations available which do not include height channels:
        • Yamaha RX-A850: 5.2, 7.2 with internal amplifier.
        • Yamaha RX-A750: 5.2, 7.2 with internal amplifier.
        • 2-ch Bi-Amp: Both models are able to bi-amp up to 2 main channels simultaneously. During bi-amplification two amplifiers are used for one speaker. One amplifier powers the midrange and tweeter section of the speaker and another amplifier powers the low frequency woofers. Each amplifier is less loaded and performs better. In order to use this feature speakers must have 2 pairs of connectors.

        7. Immersive Audio Formats

        Dolby Atmos

        Yamaha RX-A850 supports Dolby Atmos.

        • Dolby Surround Upmixer: Yamaha RX-A850 supports Dolby Surround Upmixer. If the content is not mixed in Dolby Atmos then the Dolby surround upmixer will expand the audio to all channels including ceiling speakers. The upmixer has replaced the Dolby Pro Logic II family with improved upmixing algorithms.

        8. HDMI

        Yamaha RX-A850 comes with 8 HDMI inputs. It has 2 outputs which work parallelly and output the same signal.

        Yamaha RX-A750 comes with 6 HDMI inputs. It has 1 output.

        • 4K/60Hz Passthrough: On both receivers all inputs pass up to 4K/60p 4:4:4 video signal.
        • 4K Upscaling: Both receivers can upscale up to 4K 60p 4:4:4 from HDMI and analog sources.
        • Analog To HDMI Upconversion: Both receivers support analog to HDMI Upconversion, so you can input your analog video sources and output them digitally via HDMI. This means that you will need only one HDMI cable to connect to your TV.
        • HDCP 2.2 Copy Protection: Both receivers are HDCP 2.2 compliant which is a requirement for 4K/HDR copy-protected content transmission.
        • 3D Ready: Both receivers are able to pass 3D video through HDMI.

        HDR (High Dynamic Range)

        Both receivers support HDR10 High dynamic range video has greater dynamic range than standard dynamic range (SDR) video with brighter whites and deeper blacks. The result is greater contrast and more details in dark and bright areas, better color and depth.

        9. Inputs and Outputs

        Audio

        • Phono Input: There is an MM phono input on Yamaha RX-A850 with built-in phono stage for connecting the moving magnet cartridge output of the turntable directly to the receiver.
        • Analog Pre-Outs: Yamaha RX-A850 has 7.2 preamplifier outputs which allows you to connect the receiver to the external power amplifier. You may want to use a high quality external amplifier for certain channels, usually for front L/R and center, and use the receiver to power the rest. Also, both receivers have 7 channel processing but have only 7 channel amplifiers, so they need external amplifiers connected to the analog pre-outs in order to reach their maximum speaker configurations.
        • Analog Line Inputs: There are 5 pair of line inputs on Yamaha RX-A850 and 4 pair of line inputs on Yamaha RX-A750 for connecting sources with analog outputs.
        • Digital Inputs: 2 optical inputs and 2 coaxial inputs are available for digital audio connections on both receivers.
        • Headphone Output: There is a 6.3 mm (1/4") headphone output jack on the front panel of each receiver.
