5 channel Amplifier
Onkyo TX-SR353 features 5 channel power amplifier. It is rated at 80 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven).
Onkyo TX-SR353's 5 channel amplifier can be assigned for different speaker configurations.
- Configurations: Available configurations are:
- 5.1 with internal amplifier.
- Advanced Music Optimizer: Compressed music enhancement in Onkyo TX-SR353 is done by Onkyo’s Advanced Music Optimizer. While MP3 or AAC files may sound fine through the headphones of your portable digital player, the limitations of these files can be exposed when played back through a quality home entertainment system. This is because a significant amount of high-frequency bit information is lost during the file-compression process. To counter this, Onkyo has designed the Advanced Music Optimizer to compensate for lost bit information and improve the quality of compressed audio signals. This results in a clearer and more expansive sound. Also included in this technology is a loudness correction feature that further improves the audio character of compressed files.
Onkyo TX-SR353 comes with AccuEQ room correction system and includes the calibration microphone.
- AccuEQ: First, AccuEQ detects the presence of speakers and evaluates the impedance of each. Next, it pinpoints their distance relative to the main listening position using the mic and sets suitable sound-pressure levels. Then it selects the optimal crossover frequency so that deeper bass rolls smoothly off to the subwoofer. Finally, AccuEQ performs frequency response equalization based on room-acoustic and speaker data collected via microphone. The sound-field is now tailored around the listening position, resulting in a more immersive and realistic in-film experience.
Onkyo TX-SR353 features 4 HDMI inputs. It has 1 output.
- 4K/60Hz Passthrough: All inputs pass up to 4K/60p (4:4:4) video signal.
- BT.2020 Color Space: BT.2020 or Rec. 2020 is a color standard which delivers a wider color gamut compared to Rec. 709. It covers approximately 75% of the total visual spectrum while the Rec. 709 covers only 35%.
- HDCP 2.2 Copy Protection: All inputs and outputs are HDCP 2.2 compliant which is a requirement for 4K/HDR copy-protected content transmission.
- 3D Ready: Onkyo TX-SR353 is able to pass 3D video through HDMI.
Onkyo TX-SR353 supports HDR (high dynamic range) video formats such as HDR10. High dynamic range video has greater dynamic range than standard dynamic range (SDR) video with brighter whites and deeper blacks. The result is greater contrast and more details in dark and bright areas, better color and depth.
- HDR10: HDR10 uses the wide-gamut Rec. 2020 color space. It sends static metadata via video stream to the TV which calibrates its screen brightness and color according to that. HDR10 supports 10-bit color which corresponds to 1024 shades of the primary RGB colors. It is technically limited to a maximum of 10,000 nits peak brightness, however common HDR10 contents are mastered with peak brightness from 1,000 to 4,000 nits.
Inputs and Outputs
- Analog Line Inputs: There are 3 line inputs for analog audio connection.
- Digital Inputs: 1 optical input and 1 coaxial input are available for digital audio connection.
- Headphone Output: There is a 6.3 mm (1/4") headphone output jack on the front panel.
- Inputs: 4 Outputs: 1
8K Inputs: 0
- Composite Video: Connect you VCR, Laserdisc player and other old video equipment with composite video cables.
- Inputs: 2 Outputs: 1
