Features & specs
Discrete High Current Amplification: The Onkyo TX-SR393 AV receiver utilizes discrete amplification for high instantaneous current that enhances speaker control and delivers accurate, dynamic audio reproduction. The H.C.P.S. (High Current Power Supply) allows the receiver to deliver large amounts of power necessary for reproducing the wide dynamics of movie soundtracks, plus the detail and clarity of your music. The TX-SR393's 4-channel amplifier is rated at 80 watts (into 8-ohms, at 20Hz-20kHz, with 0.08%, driving 2 channels). The Onkyo AV receiver is capable of driving 4 to 16-ohm loudspeakers.
Amplifier Assignment: The 5-channel amplifier can be configured in several ways to match your type of speaker setup.
- 5.1ch (Rear Surround): The receiver's 5 channel amplifier can be configured to create a 5.1ch Dolby Digital/DTS home theater setup with Front, Center, and Rear Surround speakers; plus a powered subwoofer.
- 5.1ch (Front Height): The receiver's 5 channel amplifier can also be configured to create a 5.1ch Dolby Digital/DTS home theater setup with Front, Center, and Front Height speakers; plus a powered subwoofer. In this application, there are no rear surround speakers.
- 3.1.2ch (Dolby Atmos/DTS:X): In addition, the receiver's 5 channel amplifier can be configured to create a 3.1.2ch Dolby Atmos/DTS:X home theater setup with Front, Center, and Overhead or Elevation speakers; plus a powered subwoofer. In this application, there are no rear surround speakers.
32-Bit Architecture: The Onkyo TX-SR393 AV receiver utilizes 32-Bit architecture with Dual 32-Bit DSP Engines and a 384kHz/32-Bit Hi-Grade DAC for exceptional sound quality. The Onkyo TX-SR393 employs powerful and highly accurate 32-bit DSP (Digital Signal Processor) engines for better surround sound reproduction. The AV receiver also incorporates a premium-quality AK4458 digital-to-analog converter from Asahi Kasei for all channels. This 384kHz/32-bit DAC implements unique low-distortion filtering technologies for clear sound, and unlocks the full potential of of your high resolution multichannel audio formats, including Dolby TrueHD and DTS-HD.
AccuEQ Speaker & Room Calibration: The TX-SR393 incorporates AccuEQ calibration technology and comes with an auto calibration microphone. Simply plug the microphone into the front-panel of the receiver and then place the mic at the main listening position. The receiver' will then automatically measure the test tones output from each speaker, and set the optimum volume level for each speaker, the crossover frequencies, and the distance from the listening position. AccuEQ also automatically adjusts the equalization of each speaker and enables correction of sound distortion caused by the acoustic environment of the room.
- It takes between 3 and 12 minutes for calibration to be completed. Each speaker outputs the test tone at high volume during measurement, so be careful of your surroundings. Also, keep the room as quiet as possible during measurement.
- You can also choose to bypass the AccuEQ auto speaker & room calibration setup and manually set the distance, crossover, EQ, and level of each speaker.
Compatible Digital Audio Formats: The AV receiver supports the following stereo & multichannel digital audio formats through its HDMI jacks and optical/coax digital inputs.
|Digital Audio Connector||Audio Signal Type||Audio Signal Format|
|HDMI (4 Inputs/1 Output)||Bitstream|| |
Dolby Atmos, Dolby Digital Plus, Dolby TrueHD, Dolby Digital
|PCM||2ch to 8ch (32-192kHz, 16/20/24-bit)|
|DSD||2ch (2.8/5.6MHz, 1-bit)|
|Optical (1 Input)/Coaxial (1 Input)||Bitstream||Dolby Digital, DTS, DTS ES, DTS 96/24|
|PCM||2ch to 6ch, (32-96kHz, 16/20/24-bit)|
Note: Even though the AV receiver will decode 7.1channel surround sound (via HDMI), it will only output 5.1ch surround because it lacks Surround Back channel speaker outputs. The receiver only supports up to 3.1.2 ch surround for Dolby Atmos and DTS:X.
Immersive Surround Sound: The Onkyo TX-SR393 AV receiver goes beyond regular surround with the latest immersive surround sound formats, including Dolby Atmos and DTS:X. The Onkyo AV receiver also supports Dolby Surround & DTS Neural:X to enhance 2-channel and multichannel decoding formats. In addition, it supports Dolby Atmos Height Virtualization (future firmware update) and DTS Virtual:X for multi-dimensional sound from a standard 5.1ch setup.
- Dolby Atmos: Dolby Atmos surround sound technology dispenses with channel-based coding in favor of more advanced object-based coding, giving the soundtrack designer the ability to precisely place sounds anywhere in the 3-dimensional space. Now you can enjoy this same award-winning technology at home with the TX-S393 that lets you connect a 3.1ch surround sound speaker system and two additional overhead speakers or two Dolby Atmos elevation speakers for a 3.1.2ch surround sound experience (there are no rear speakers in this setup).
- Dolby Surround: Dolby Surround offers an enhanced cinema experience to your 2ch or multichannel movie soundtracks using your existing 5.1ch or 3.1.2ch speaker setup. Dolby Surround enhances audio definition by improving the spatial dimension and overall audio definition of movie soundtracks. It does this by using four distinct surround zones that provide greater control over the exact placement of each detail in a movie sound track, so audio can be matched more accurately to the video on screen; this means more depth and greater realism for your movies. As a result, individual sounds are clearer and more distinct. It also improves the surround sound experience across the entire theater by widening the listening "sweet spot".
- Dolby Atmos Height Virtualization (via future firmware update): Dolby Atmos Height Virtualization provides immersive audio without height-channel or overhead speakers, creating virtual height effects in a 5.1ch or 2.1ch speaker arrangement. Dolby Atmos Height Virtualization applies carefully designed "height-cue" filters to the overhead audio components of your content's soundtrack before they are mixed into your loudspeakers to create the sensation of sound above you.
- DTS:X: The latest immersive surround sound system, DTS:X features object-based audio coding that lets the soundtrack designer place sonic elements anywhere in the 3D acoustic soundspace, and provides for overhead speakers to deliver a stunning surround sound experience. The TX-SR393 supports up to a 3.1.2ch DTS:X home theater setup (there are no rear speakers in this application).
- DTS Neural:X: DTS Neural:X is an advanced spatial remapping technology from DTS, which provides a fully immersive output for all types of source content; this includes DTS bitstreams and non-encoded (PCM) data. DTS Neural:X delivers a thrilling sense of immersive sound to your speaker layout regardless of the original source format.
- DTS Virtual:X (via future firmware update): DTS Virtual:X bridges the gap between DTS:X and the reality of so many consumers' homes that cannot accommodate overhead speakers, allowing you to enjoy multi-dimensional sound regardless of room size, layout, or speaker configuration. DTS Virtual:X can be used with any content (from 2ch to 7.1.4ch soundtracks), while delivering virtual height & virtual surround processing based on psychoacoustics (not reflective surfaces).
Onkyo Original DSP Modes: Onkyo's Original DSP Modes, combined with Dolby Digital & DTS processing, produce more realistic, powerful sound effects for your movie and music sound tracks based on the type of content and your home theater setup. You can choose from the following:
- Orchestra: Suitable for classical or operatic music. This mode emphasizes the surround channels in order to widen the sound image, and simulates the natural reverberation of a large hall.
- Studio-Mix: Suitable for rock or pop music. Listening to music in this mode creates a lively sound field with a powerful acoustic image, like being at a club or rock concert.
- TV Logic: Suitable for TV shows produced in a TV studio. This mode enhances the surround effects to the entire sound to give clarity to voices and create a realistic acoustic image.
- Unplugged: Suitable for acoustic instruments, vocals and jazz. This mode emphasizes the front stereo image, giving the impression of being right in front of the stage.
- Multichannel (Multich)/Game: Multichannel mode is suitable for playing sources recorded in multichannel PCM. The receiver also offers four different Gaming modes - RPG, Action, Rock, and Sports.
- Stereo/All Channel Stereo (AllCh Stereo): In Stereo mode, sound is output from the front left and right speakers and subwoofer. In All Channel Stereo Mode, stereo sound is output from all speakers - ideal for background music.
- Mono/Full Mono: In Mono mode, when the input signal is analog or PCM, the left and right front speakers output the sound in monaural. In Full Mono mode, all speakers output the same sound in mono, so the sound you hear is the same regardless of where you are within the listening room.
- Theater-Dimensional (T-D): In this mode, you can enjoy a virtual playback of multichannel surround sound even with only two or three speakers. This works by controlling how sounds reach the listener's left and right ears
Direct Mode: The Direct listening mode can be selected for all input signals. In this mode, processing that affects sound quality is shut down, and sound closer to the original is reproduced. The sound is reproduced with the soundfield based on the number of channels in the input signal. For example, a 2ch signal is output only from the front speakers. Note that other sound adjustments are not available when this mode is selected.
Audio Enhancements: The Onkyo TX-SR393 receiver provides various audio enhancements to deliver a high-quality listening experience every time.
- CinemaFilter: The CinemaFilter softens overly bright movie soundtracks. Movie soundtracks are typically mixed for a large theater (relative to your home theater) with lots of soft seats and thick curtains on the walls. Home theater settings often lack these high frequency absorbing wall treatments, making the soundtrack sound too bright. CinemaFilter accounts for this and for many movies sounds more natural at home.
- Music Optimizer: The Music Optimizer function enhances
the sound quality of compressed music files. The Music Optimizer function
only works with PCM digital audio input signals with a sampling rate below
48kHz, analog input signals, and Bluetooth audio.
- Late Night: The Late Night feature limits the dynamic range of Dolby Digital recordings. Limiting the dynamic range makes it easier to find a volume that ensures the quiet sounds are not too quiet and the loud sounds are not too loud for night time listening. This allows you to comfortably listen to without the need to constantly adjust the volume to keep from waking family/neighbors. The choices are: Off, Low, and High. This feature only works with Dolby Digital Encoded software and the depth of the feature will vary based on the individual software package.
- Vocal Mode: The Vocal mode emphasizes movie dialog and music vocals, so you can hear them more easily amongst the movie effects and musical instruments. The Vocal mode can be set from 1 (low) to 5 (high).
Bass Management: The Onkyo AV receiver offers Tone Control and Double Bass feature to get the most bass impact out of your system. You can independently adjust the Bass (20Hz) and Treble (20kHz) of the receiver's Front L/R channels from -10 to +10 dB. You can also activate the Double Bass function in order to boost bass output even more by feeding bass sounds to the front left/right speakers, center-channel, and powered subwoofer.
Volume & Level Setup: The Onkyo AV receiver provides the following volume & level settings.
- IntelliVolume: With IntelliVolume, you can set the input level for each input (-12 to +12dB) selector individually. This is useful if one of your source components is louder or quieter than the others.
- Maximum Volume: Use this feature to set the receiver's maximum volume level for the Main Zone. This feature is useful to avoid turning the volume too loud by mistake. You can set the Max Volume from 50-99, or Off (disabled).
- Power On Volume: Use this feature to set the volume level when the power is turned on in the Main Zone. You can choose between Last (same as the volume when the unit was turned off), Min, or 1-99, or Max.
- Mute Level: Set the volume lowered from the listening volume when "Mute" is selected. Choose from 0, -40dB, or -20 dB.
- Headphone Level: With this setting, you can specify the headphone volume (-12 to +12dB) relative to the main volume. This is useful if there's a volume difference between your speakers and your headphones.
Analog Audio Outputs: The Onkyo TX-SR393 is outfitted with the following analog audio outputs.
- Speaker Terminals: The front main speaker outputs consist of binding post terminals that will accept bare wire (up to 10AWG), pin-connectors, and banana plugs (single only). The center and surround speaker outputs consist of spring-clip terminals that will accept bare wire (up to 10 AWG) or pin-connectors. The receiver will support connection of 4-ohm to 16-ohm speakers (there is an impedance setting in the receiver's on-screen menu).
- Dual Subwoofer Outputs: The receiver is fitted with two subwoofer outputs to connect dual powered subs for extra bass. The dual outputs are wired in parallel and share the same input signal (they are not discrete).
- Zone B: The receiver provides a Zone B preamp output that lets you connect a separate amplifier and pair of speakers in a second room so you can enjoy the same source of your Main Zone in another room, or turn the Main Zone off and only listen to an audio source in Zone B. When the Main Zone and Zone B are played at the same time, you are limited to 2ch Stereo or All-Channel Stereo in the Main Zone. The volume level of Zone B can be controlled from the Onkyo receiver (shared with Main Zone) or your Zone B amplifier. *Zone B does not allow you to play a different source than the main zone.
- Headphones: When headphones are plugged into the full-size 1/4" jack on the front panel, all the speakers are automatically muted. The receiver supports headphones with impedances of 8 to 600-ohm.
ARC (Audio Return Channel): The receiver's HDMI monitor output features ARC (Audio Return Channel). This feature allows audio to be sent from your compatible TV to your receiver through the same HDMI cable already being used to send audio and video to your television. This eliminates the need for extra cables connected to your TV.
HDMI 2.0b: The Onkyo TX-SR393 has four HDMI 2.0b inputs and one HDMI 2.0b output. Thanks to the its HDMI 2.0b specification, the receiver can support 4K/60 Hz Ultra-HD video, HDCP 2.3 compatibility, 4:4:4 color sub-sampling, High Dynamic Range (HDR), and BT.2020 Wide Color Gamut.
- 4K/60Hz w/ Upscaling: The TX-SR393 supports up to 4K (3840x2160 or 4096x2160 pixels) video @ 60 frames per second on all of its HDMI inputs and output. It will also pass a 480p, 720p, 1080i, or 1080p video signals via HDMI (not compatible with 480i video signals).The receiver can even upscale 1080p HDMI video sources to 4K Ultra HD (3840x2160 pixels).
- HDCP 2.2 Compliance: The receivers HDMI inputs and HDMI monitor output support the latest HDCP 2.2 certification, which fully complies with the latest copyright protection standard for 4K video transmission. The unit will offer HDCP 2.3 support via a future firmware update (no ETA).
- 4:4:4 Color Subsampling: The receiver's HDMI inputs and HDMI monitor output support RGB/YCbCr 4:4:4 (8-bit), YCbCr 4:2:2 (12-bit), and YCbCr 4:2:0 (8/10/12-bit) color subsampling (@ 60Hz or 50Hz). With 4:4:4 color subsampling, luminance (brightness) and chroma (color) are sampled at the same rate; resulting in an RGB color palette as big as the video sampling rate for a video image with more colors, plus greater color accuracy and detail.
- Wide Color Gamut (BT.2020): The BT.2020 color standard delivers a much wider color gamut and represents about 75% of the total visual color spectrum, while the current Rec. 709 color standard selected as the color space for HDTVs and early generation 4K Ultra HDTVs covers only 35% of the total visual color spectrum.
Note: This receiver does not contain any analog video inputs or outputs.
HDR (High Dynamic Range): HDR (High Dynamic Range) video provides enhanced picture quality by simultaneously enabling greater detail for both the dark and bright parts of an image. HDR reproduces a greater dynamic range of luminosity or brightness levels, creating greater contrast. This increased contrast reveals the subtle nuances of the image, from detailed blacks and shadows to the brightest whites and colors, plus greater depth. This receiver supports two HDR formats - HDR 10, Hybrid Log-Gamma (HLG), & Dolby Vision.
- HDR 10: HDR 10 is an open standard and currently the most popular HDR format on the market. It uses static metadata at the start of a movie to tell the receiver and your TV that the video content is encoded using HDR.
- Hybrid-Log Gamma: HLG (Hybrid-Log Gamma) is primarily designed for live video feed and over-the-air broadcasts. It uses no pre-encoded metadata and is backwards compatible with SDR. HLG's native compatibility allows much of today's existing SDR infrastructure to be re-used for HDR in the future.
- Dolby Vision: Unlike HDR 10 which contains static metadata and HLG which uses no metadata, Dolby Vision uses dynamic metadata technology which sets individual color and brightness levels for each and every scene. Dolby works directly with filmmakers at major Hollywood studios to create superior HDR video masters of blockbuster movies.
Note: Use a premium high-speed 18Gbps HDMI cable for the best 4K/HDR performance.
Other HDMI Features: The TX-SR393 AV receiver's HDMI connectivity also offers 3D video pass-through, Deep Color & x.v. Color support, as well as an auto LipSync function.
