        7. Speaker Configurations

        Sony STR-DH770's and Sony STR-ZA3000ES's amplifiers can be assigned for different speaker configurations.

        • Configurations: Available configurations are:
        • Sony STR-DH770: 5.2, 7.2 with internal amplifier.
        • Sony STR-ZA3000ES: 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.

        8. HDMI

        Sony STR-DH770 comes with 4 HDMI inputs. It has 1 output.

        Sony STR-ZA3000ES comes with 6 HDMI inputs. It has 2 outputs - 1 Main and 1 Sub/Zone2.

        • 4K/60Hz Passthrough: On both receivers all inputs pass up to 4K/60p (YCbCr4:4:4) video signal.
        • 4K Upscaling on Sony STR-ZA3000ES: It can upscale up to 4K/60p from HDMI sources.
        • BT.2020 Color Space: BT.2020 or Rec. 2020 is a color standard which delivers a wider color gamut compared to Rec. 709. It covers approximately 75% of the total visual spectrum while the Rec. 709 covers only 35% (available on Sony STR-DH770 only).
        • 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)

        Sony STR-DH770 supports HDR10

        Sony STR-ZA3000ES does not support HDR. 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

        • Analog Pre-Outs: Sony STR-ZA3000ES 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 4 pair of line inputs on both receivers for connecting sources with analog outputs.
        • Digital Inputs: 1 optical input and 1 coaxial input are available on Sony STR-DH770 and 2 optical inputs and 1 coaxial input are available on Sony STR-ZA3000ES for digital audio connections.
        • Headphone Output: There is a 6.3 mm (1/4") output jack on Sony STR-DH770 for headphones.
