Sony STR-DH790: A 7.2 Channel 4K/60p Home Theater Amplifier

The Sony STR-DH790 is a 7.2 channel AV receiver designed to transform your living room into a true cinema experience. It supports immersive audio technologies Dolby Atmos and DTS:X, providing a three-dimensional sound experience. These surround sound formats precisely place sound effects in space, including above the listener, creating an enveloping and realistic sound bubble.

The amplifier features 7 channels of amplification, allowing for a 5.1.2 system configuration with two height speakers or a classic 7.1 system. Its output power of 145 W per channel (at 6 ohms, 1 kHz, THD 0.9%, 1 channel driven) ensures dynamic and powerful sound reproduction, capable of effectively filling medium to large-sized rooms.

Exceptional Image Quality

The STR-DH790 excels not only in audio but also in image quality. It is compatible with the latest 4K HDR video standards, ensuring lossless pass-through for Ultra HD content. The amplifier supports HDR10, HLG (Hybrid Log-Gamma), and Dolby Vision formats, guaranteeing vibrant colors, striking contrasts, and deep blacks.

HDCP 2.2 compatibility allows for seamless playback of protected 4K content, while BT.2020 support ensures faithful reproduction of extended color spaces. 3D enthusiasts will also be pleased, as the amplifier can transmit 3D signals via HDMI.

Connectivity and Flexibility

The Sony STR-DH790 offers connectivity suited to modern needs. It features 4 HDMI inputs and 1 HDMI output, all compatible with 4K/60p and 4:4:4. The eARC (Enhanced Audio Return Channel) function on the HDMI output allows for receiving high-resolution audio formats from a compatible TV.

For audio sources, the amplifier offers 4 analog RCA inputs, 1 optical input, and 1 digital coaxial input. A front USB port allows you to charge your mobile devices. Speaker connections are made via spring terminals, except for the front channels which benefit from screw terminals.

Wireless connectivity is also present with Bluetooth, allowing easy music streaming from a smartphone or tablet. The Bluetooth Standby function even allows you to turn on the amplifier remotely from a paired device.

Ease of Use and Calibration

Sony has focused on ease of use with an intuitive graphical interface accessible via the HDMI output. The main menu provides quick access to the amplifier’s various functions and settings.

System calibration is simplified with Advanced Auto Calibration technology. Using the supplied microphone, the amplifier analyzes the room’s acoustics and automatically adjusts the speaker settings for the best possible sound. The automatic phase matching function ensures optimal coherence between the left and right front speakers.

Sound Modes and Customization

The STR-DH790 offers a variety of sound modes to suit different types of content. In addition to classic surround modes, there are options like “Front Surround,” which simulates an enveloping sound with only two front speakers, ideal for confined spaces.

The amplifier also includes an audio optimizer that enhances the sound quality of compressed sources, as well as a Pure Direct mode that bypasses digital processing for the most faithful reproduction of stereo sources.
