In this section we present pros and cons of Sony STR-DH770.

7 channel Amplifier

Sony STR-DH770 features 7 channel power amplifier. It is rated at 90 W (6 Ω, 20 Hz - 20 kHz, 2 channel driven).

Speaker Configurations

Sony STR-DH770's 7 channel amplifier can be assigned for different speaker configurations.

• Configurations: Available configurations are:
5.2, 7.2 with internal amplifier.
• 2-ch Bi-Amp: Sony STR-DH770 allows you 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.

Sound Processing

Room Calibration

Sony STR-DH770 comes with D.C.A.C. room correction system and includes the calibration microphone.

HDMI

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

• 4K/60Hz Passthrough: All inputs pass up to 4K/60p (YCbCr4:4:4) video signal.
• 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%.
• HDCP 2.2 Copy Protection: All inputs and outputs are HDCP 2.2 compliant which is a requirement for 4K/HDR copy-protected content transmission.
• 3D Ready: Sony STR-DH770 is able to pass 3D video through HDMI.

andh3>HDR (High Dynamic Range)

Sony STR-DH770 supports HDR (high dynamic range) video formats such as 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.

• HDR10: HDR10 uses the wide-gamut Rec. 2020 color space. It sends static metadata via video stream to the TV which calibrates its screen brightness and color according to that. HDR10 supports 10-bit color which corresponds to 1024 shades of the primary RGB colors. It is technically limited to a maximum of 10,000 nits peak brightness, however common HDR10 contents are mastered with peak brightness from 1,000 to 4,000 nits.

Audio

• Analog Line Inputs: There are 4 line inputs for analog audio connection.
• Digital Inputs and Outputs: 0 optical input, 1 optical output and 1 coaxial input are available for digital audio connection.
• Headphone Output: There is a 6.3 mm (1/4") headphone output jack on the front panel.

Video

• HDMI:
Inputs: 4   Outputs: 1
8K Inputs: 0
• Composite Video: Connect you VCR, Laserdisc player and other old video equipment with composite video cables.
Inputs: 2   Outputs: 1
