Onkyo TX-SR393 5.2-Channel Audio And Video Receiver

The Onkyo TX-SR393 5.2-Channel Audio and Video Receiver produces a room-filling sound with an output of up to 80W per channel at 8 Ohms. AccuEQ sound calibration adjusts the sound to the unique acoustics of your room. You can stream music wirelessly from your preferred Bluetooth-enabled devices with the built-in Bluetooth connectivity.

Four HDMI inputs and one HDMI output are provided by the Onkyo TX-SR393. For the reproduction of display-based audio, such as the built-in streaming applications on your TV, the HDMI output supports ARC. You can quickly and easily connect your receiver using the rear-panel easy connection guide.

TX-SR393 Lifestyle

DTS:X Sound and Dolby Atmos

In order to give the impression that sound is moving all around you, these two sound technologies combine audio in 3D space utilizing object-based encoding rather than channel-based encoding. To create the illusion of 3D audio, Dolby Surround and DTS Neural:X upmix localization cues from vintage stereo or multichannel soundtracks.

HDMI Support for HDR and 4K

Every HDMI terminal on the receiver is capable of 4K/60 Hz, HDR10, HLG, Dolby Vision, BT.2020, and HDCP 2.2. Audio Return Channel (ARC) is supported on the HDMI output for the reproduction of display-based audio, such as that from built-in apps. An OSD window allows you to check the status of the A/V input and output.

Discrete Amps

A high current is delivered to the speakers by the receiver’s discrete amps, high-output transformer, and huge capacitors in order to improve speaker control for quick transient response, a broad dynamic range, and precise, clear sound.

Streaming Bluetooth audio

Whatever is playing on your compatible mobile device, laptop, or computer is sent wirelessly to your home theatre through Bluetooth. The receiver can begin playback automatically the moment it recognizes an incoming Bluetooth audio stream from your device after pairing and remembering it.

AccuReflex and AccuEQ Room Acoustic Calibration

AccuEQ configures the size, placement, and sound pressure levels of speakers. The appropriate subwoofer crossover setting is then chosen, and equalization is applied to all of your speakers. AccuReflex is intended to eliminate phase-shift brought on by the changes in sound route between directional and non-directional sounds during object-based audio reproduction through Dolby Atmos-capable speakers. Together, these components offer a 3D soundstage with overhead dimensionality and vertical movement, which aids in localization.

Optimized Music Player

Lossy files, like MP3s, are practical but have relatively low fidelity due to data lost during compression. With these file types, advanced music optimization technology aids in the restoration of lost information for improved sound quality. Additionally, Bluetooth streaming playback quality is enhanced in this mode.

DTS Virtual:X virtual 3D sound

No matter the speaker layout, including rear, surround, or height speakers, DTS Virtual:X is made to produce an immersive 3D soundfield. It works with large or tiny speakers and employs DSP-based techniques to put you in the centre of a multidimensional soundfield with height and surround effects. DTS Virtual:X supports non-encoded stereo, various DTS formats, and DTS:X soundtracks in the 3D space.

Clear Communication with the Touch of a Button

The DSP-controlled Vocal Enhancer on the Onkyo TX-SR393 allows you to raise or lower vocal frequencies to your preferred levels by using the keys on the remote or the tone controls on the receiver’s front panel.

Zone B Line-Out

You can connect audio sources linked to the Onkyo TX-SR393 receiver, such as digital audio through HDMI, optical, or digital coaxial, to a component with an analogue RCA line input via the Zone B line-out. To enjoy your media without disturbing those around you, attach a transmitter that supports wireless headphones or share sound to a surrounding area.

Connect and Power Your Media Streaming Device

Select HDMI media streaming devices are powered by a rear-panel USB power output, allowing you to improve your home theatre with on-demand network entertainment without adding extra power cords.

Rear-Panel Setup Guide Aids in Connection Simplicity

On the back panel of the Onkyo TX-SR393 has  connections for speakers as well as extra devices shown and identified. Images make it easier to see upside-down diagrams when leaned over the top of the receiver.

A future firmware update will include support for Dolby Atmos Height Virtualizer

Engaging the Dolby Atmos Height Virtualizer while playing any Dolby format enhances the listening experience by simulating the surround and height effects of conventional speaker configurations. Future firmware updates are expected to include this feature.

Polk Audio CSR Centre Channel Speaker

Polk Audio CSR centre channel speaker was created to deliver excellent sound at an affordable cost. With driver innovations from Polk’s higher-end speaker lines, the CSR reproduces fine dialogue and sound effects from motion pictures. For seamless home theatre surround sound, pair it with the R150 bookshelf speakers or the R300 tower speakers.

Smooth, accurate response is provided by Polk’s proprietary Dynamic Balance® drivers for natural and detailed sound. The speaker is prepared for even the most dramatic movie soundtracks thanks to rubber surrounds that boost the speaker’s longevity and power handling. The Polk Audio CSR has a sturdy MDF cabinet that resists vibrations that could muddy the sound, and it has a sleek black appearance that complements many TVs and entertainment centres. A unusual feature for a speaker in this price range, the speaker’s five-way binding posts on the back allow for a safe connection to your receiver or amp.

Dynamic Balance: Dynamic Balance is a proprietary Polk Audio technology using laser imaging to determine what combination of speaker materials create the least amount of resonance. Eliminating resonance in speakers results in a wide, smooth response and low distortion.

Polymer Composite Woofers: The speaker features two lightweight, yet stiff mineral-filled polymer composite woofers with good damping, giving you high efficiency, excellent bass, and low distortion. For high performance durability, each woofer uses a butyl rubber surround and an acoustically inert stamped driver basket.

Silk/Polymer Tweeter: The speaker has a 0.75″ fabric/polymer dome tweeter with a neodymium magnet that provides clear, detailed highs.

Mylar Capacitors: The speaker utilizes Mylar bypass capacitors to extend its high frequency response and improve detail and transparency.

Acoustically Inert Cabinet: The speaker cabinet features all-MDF construction with internal bracings that virtually eliminate sound-muddying resonance.

Port: There is a single critically-tuned port opening on the rear of the speaker that has low port noise for increased and extended bass response.

Grille: The speaker features a removable anti-diffraction cloth grille that minimizes grille diffraction for spacious, three-dimensional imaging.

5-Way Binding Posts: The 5-way binding posts will accept bare wire, pin connectors, spade connectors, banana plugs, and dual banana plugs.

Magnetically Shielded: The speaker is magnetically shielded, allowing you to place it on your television without distorting the picture.

Timbre-Matched: The Polk CSR is designed to be used as a center-channel in any Polk Audio home theater or multi-channel music system for a more realistic seamless surround sound environment.

Mounting: The center-speaker comes with 4 rubber self-adhesive feet to help secure the speaker in place to prevent slippage and vibration. The center-speaker does not come with any type of wall-bracket or key-hole slot for wall-mounting the speakers.
