TX-SR393 Amplificador AV 5.2 ONKYO
Dolby Atmos and DTS:X sound is here
The TX-SR393 supercharges your Dolby Atmos and DTS:X experience. Object-based audio is mixed in 3D space and lets any play through any speaker, tracking the action, localizing effects, and moving around you. Dolby Surround and DTS Neural:X complement native 3D audio playback. These technologies find localization cues in legacy stereo or multichannel soundtracks and upmix these elements to create immersive top-to-bottom dimensionality.
Dolby Atmos Height Virtualizer
When playing any Dolby format, engaging Dolby Atmos Height Virtualizer enables a more immersive listening experience, creating a virtual surround and height effect from traditional speaker layouts without employing additional surround or height speakers.
Spatial sound elevated with DTS Virtual:X
DTS Virtual:X is a new surround-sound virtualization technology that creates an immersive 3D soundfield from any speaker layout, such as 2.1, 3.1, and 5.1 configurations without height, surround, or rear surround speakers deployed. It uses sophisticated DSP-based algorithms to place the audience at the center of a multidimensional soundfield with height and surround spatiality, and is equally effective in large or small spaces. DTS Virtual:X works in the 3D domain with DTS:X soundtracks, DTS formats, and non-encoded stereo.
Ready for 4K HDR entertainment
Enjoy comprehensive support for 4K/60p and HDR (High Dynamic Range) video formats including HDR10, HLG, Dolby Vision, and BT.2020. The 4:4:4 color-space is also supported. All four HDMI inputs and ARC-ready output pass video from player to your compatible TV, unlocking everything the latest films and games have to offer. You can easily confirm A/V input-output status via a new OSD window.
More power, more realism, more magic
It´s tempting to see watts as the most important figure on an amp´s spec sheet. However, watts are an indication of loudness, not sound quality. Amperes – electrical current – tell the real story. The more current an amplifier develops, the better it controls the speaker. Better control equals fast transient response, wide dynamic range, and clear, accurate sound. The high-output transformer, large capacitors, and discrete amps inside the TX-SR393 produce discrete amps inside the TX-SR393 produce the most current in its class. And that´s one big reason why it sounds as good as it does.
AccuEQ Room Acoustic Calibration with AccuReflex
AccuEQ creates a harmonious soundfield in your room. It detects speaker presence, size, and distance from a measurement position, and sets sound-pressure levels. It then selects the ideal subwoofer crossover and applies equalization to all speakers. AccuReflex optimizes object-based audio reproduction through Dolby Atmos-enabled speakers. It resolves phase-shift arising from path differences between directional and non-directional sounds. Enjoy improved localization and a 3D field with vertical movement and overhead dimensionality.
Hear dialog clearly at the touch of a button
Finally, a fast and effective solution to inaudible dialog in TV programs and movies. The TX-SR393 features DSP-controlled Vocal Enhance that 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.
Simple steps to sweet sound
The TX-SR393 simplifies your room´s entertainment setup. Components plug into labelled ports while your TV connects via one easy-to-conceal HDMI cable. Hook up your speakers as shown by a friendly diagram next to the numbered speaker terminals. Setup takes moments, enjoyment is limitless.
Smooth and easy Bluetooth streaming
Whatever audio is playing on your phone, tablet, or PC app can be streamed to the TX-SR393 with Bluetooth wireless technology. Once the receiver has paired with and remembered your device, it will start playback automatically whenever it detects an incoming Bluetooth audio stream.
Decompress with Advanced Music Optimizer
When an audio file is squeezed into a small container (such as MP3), high-frequency data is lost. This can affect sound quality. Onkyo´s Advanced Music Optimizer DSP listening mode reconstructs the missing big data. Playback quality is greatly improved, while you enjoy the same convenient file sizes. This mode also optimizes Bluetooth streaming playback quality.
