Dolby Atmos & DTS:X

Dolby Atmos & DTS:X

The HT-S3910 supercharges your Dolby Atmos and DTS:X experience. Object-based audio is mixed in 3D space and lets individual sounds play through any speaker, tracking the action and placing sounds all around you. Dolby Surround® and DTS® Neural:X complement 3D audio playback. These technologies find localisation cues in legacy stereo or multichannel soundtracks and upmix these elements to create immersive top-to-bottom dimensionality.

DTS Virtual:X

DTS Virtual:X

DTS Virtual:X is a new sound virtualisation technology that creates an immersive 3D soundfield from any speaker layout, such as 2.1, 3.1, and 5.1 setups with no need for height, surround, or rear surround speaker connection. It uses DSP-based algorithms to place the audience at the centre of a multidimensional soundfield with height and surround spatiality, and is effective in large or small spaces. DTS Virtual:X works with DTS:X, DTS formats, and non-encoded stereo.

Height Virtualiser

Height Virtualiser

When playing any Dolby format, engaging Dolby Atmos Height Virtualiser enables a more immersive listening experience, creating a virtual surround and height effect from traditional speaker layouts without employing additional surround or height speakers.

Space Saving Speakers That Pack A Punch

Space Saving Speakers That Pack A Punch

Want space-filling sound without speakers dominating the room? The supplied Onkyo system is factory-matched to harmonise with the amp’s unique sound signature. These compact units are pleasingly heavy thanks to large magnets and full-range drivers. Neat size makes for easy placement, even on the wall, while cloth-wrapped baffles protect against curious young fingers. With a small footprint and down-firing 16 cm cone, the powerful 120 W sub can be placed wherever you want—deep bass adds impact to LFEs in games and movies.

High Current, Great Sound

High Current, Great Sound

Watts seem like the most important number on an amp’s spec sheet. However, they only indicate loudness, not audio quality. Amperes current are the secret to good sound. More current gives a tighter grip on the speaker cones, helping to control their travel with greater precision. Speaker control means faster dynamics, clearer detail, and more life. The HT-S3910 features a High-Current Low-Noise Power Transformer, large custom audio capacitors, and discrete high-current amps that deliver the highest flows of current in their class. Expect rhythmically exciting, energetic sound from any source.

Supports 4K HDR Video Formats

Supports 4K HDR Video Formats

This receiver has four HDMI inputs and one ARC-enabled output that support 4K/60p video, HDR formats (HLG, HDR10, Dolby Vision, and BT.2020), and the ultra-large 4:4:4 color-space. Video passes from player to your 4K HDR-ready TV, while the receiver decodes and amplifies the audio. It’s easy to check your player, receiver, and TV are working in harmony by calling up a new media input-output on-screen display using the remote control.

Fix Inaudible Dialog By Touching A Button

Fix Inaudible Dialog By Touching A Button

We include a quick and effective function to solve the problem of inaudible dialog in TV programs and movies. DSP-controlled Vocal Enhancer identifies vocal frequencies and allows you to raise or lower them to taste using keys on the remote or via the tone controls on the receiver’s front panel.

Share Sound Or Enjoy Privately

Share Sound Or Enjoy Privately

Any hi-fi system with an analog RCA input can be connected to the A/V receiver’s Zone B line output. Now you can share audio (including SPDIF and HDMI) to the hi-fi in Zone B, or play in both Main Room and Zone B simultaneously. Alternatively, connect a compatible transmitter and enjoy audio from any A/V source on your wireless headphones.

Simple Steps To Sweet Surround

Simple Steps To Sweet Surround

The HT-S3910 simplifies your home entertainment setup. Conceal the receiver and players in an entertainment unit. A single HDMI cable links TV to receiver for a super-clean look. Check the easy-to-follow diagram on the rear panel to hook up the speakers. The process takes moments, enjoyment is limitless.

Bluetooth Wireless Technology With Advanced Music Optimiser

Bluetooth Wireless Technology With Advanced Music Optimiser

Whatever audio is playing on your phone, tablet, or PC app can be streamed to the receiver with Bluetooth wireless technology. Compressed audio commonly stored on or streamed from smartphones, such as MP3 or AAC, is enhanced by Advanced Music Optimizer, a DSP technology that restores high-frequency bit data for rich, clear sound.

USB Power For Streaming Dongles

USB Power For Streaming Dongles

A USB terminal on the rear panel powers any media streaming stick plugged into an adjacent HDMI input—great if you don’t have enough power-points.
