Denon AVR-S750H AV Receiver

The Denon AVR-S750H AV receiver is a 7-channel network receiver designed to manage a home cinema system and music sources. Six HDMI inputs bring connections for a television, players and gaming devices together in one system. Surround sound processing includes Dolby Atmos, DTS:X and DTS Virtual:X. Operation of Dolby Atmos Height Virtualization may depend on the installed firmware version.

The discrete 7-channel amplifier powers each channel separately. Its stated maximum output is 140 W per channel. As the measurement conditions are not provided, this figure should not be compared directly with power ratings for other amplifiers that have been measured under fully specified conditions.

Video and television connections

Six HDMI inputs accommodate systems with several video sources. One HDMI output connects a television or projector. This connection set does not provide a separate second HDMI video zone.

The HDMI section supports HDCP 2.3 and 4K Ultra HD video transmission at up to 60 Hz. It also supports 4:4:4 colour resolution, BT.2020, HDR10, Dolby Vision and Hybrid Log-Gamma.

eARC carries compatible surround sound from a television through the same HDMI cable. This is useful for television apps and sources connected directly to the TV. HDMI-CEC allows basic functions to be controlled with many compatible television remote controls.

Music playback and network features

Built-in HEOS technology enables music streaming over Wi-Fi and can form part of a compatible multi-room audio system. Audio can also be streamed through Bluetooth or Apple AirPlay 2.

The HEOS ecosystem was designed to offer Spotify, Tidal, TuneIn and Deezer services, controlled through the HEOS app. Online service availability may change according to the app, region and service provider decisions.

The model was designed for control through Amazon Alexa, Google Assistant and Apple Siri. Siri is used through a compatible Apple ecosystem. Current voice-feature operation depends on continuing support from the relevant platforms.

Initial setup

The graphical Denon Setup Assistant guides users through the initial connection and system options step by step.

This feature is described only as a graphical initial setup environment. The supplied information does not confirm automatic room measurement, sound correction functions or the inclusion of measurement accessories. These capabilities should therefore not be assumed from this description alone. If they are important to a particular system, check the documentation supplied with the unit being offered.

The available material also does not identify the regional variant, finish or hardware revision. Check these details against the markings on the specific unit, particularly when integrating it with existing equipment or when a required feature may depend on firmware.

Placement and cable planning

Place the receiver on a stable, open shelf with enough room for air circulation. Do not cover its ventilation openings with other equipment. Free heat dissipation is important while the seven-channel amplifier is operating.

Allow room behind the unit for HDMI and speaker cables so that the connections are not bent sharply. Plan the system position with the single HDMI output in mind.

FAQ

Can I connect a television and projector at the same time?

The receiver has one HDMI output, so one display device can be connected directly. A two-screen system would require additional external equipment.

How can I send sound from television apps to the receiver?

Use the compatible eARC HDMI connection on the television. It can carry supported surround sound to the receiver through the same HDMI cable.

Will Dolby Atmos Height Virtualization work without further checks?

Operation may depend on the installed firmware version. If this capability is important, check the firmware version of the specific unit before choosing it, as the required version is not stated in the supplied material.

Can the 140 W rating be compared directly with other amplifiers?

Not always. The impedance, frequency range, distortion level and number of channels driven simultaneously are not specified. These conditions are necessary for an accurate power comparison.

Where should I place the receiver?

Choose a stable, well-ventilated shelf and leave space for routing the rear cables. Because the dimensions and weight are not provided, confirm that the shelf is suitable for the specific unit.

Do the online music and voice services still work?

These functions depend on the region, apps and external service providers. Their availability may change independently of the receiver hardware.
