      Amplifier

      Onkyo TX-SR373 Onkyo TX-SR353

      5 channel Amplifier: Onkyo TX-SR373 features 5 channel power amplifier. It is rated at 80 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven).

      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).

        Speaker Configurations

        Onkyo TX-SR373's and Onkyo TX-SR353's amplifiers can be assigned for different speaker configurations.

        • Configurations: Available configurations are:
        • Onkyo TX-SR373: 5.2 with internal amplifier.
        • Onkyo TX-SR353: 5.1 with internal amplifier.

          • Sound Processing

          • Compressed Music Enhancer: Onkyo TX-SR373 and Onkyo TX-SR353 feature Compressed Music Enhancer which enhances the quality of the music files with lossy compression.
          • Advanced Music Optimizer: Compressed music enhancement in Onkyo TX-SR373 and 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.

          Room Calibration

          Onkyo TX-SR373 and Onkyo TX-SR353 come with AccuEQ room correction system.

          • 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.

        Video Section

        HDMI

        Onkyo TX-SR373 and Onkyo TX-SR353 come with 4 HDMI inputs. It has 1 output.

        • 4K/60Hz Passthrough: On both receivers 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% (available on both models).
        • HDCP 2.2.0 Copy Protection: Both receivers are HDCP 2.2.0 compliant which is a requirement for 4K/HDR copy-protected content transmission.
        • 3D Ready: Both receivers are able to pass 3D video through HDMI.

        HDR (High Dynamic Range)

        Onkyo TX-SR373 supports HDR10 and Dolby Vision.

        Onkyo TX-SR353 supports 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.
        • Dolby Vision: Dolby Vision is a set of technologies developed by Dolby Laboratories for high dynamic range (HDR) video. It covers content creation, distribution, and playback. Like HDR10+, it includes dynamic metadata that are used to adjust and optimize each frame of the HDR video to the consumer display's capabilities in a way specified by the content creator. Dolby Vision allows for a maximum resolution of 8K up to 12-bit color depth, maximum peak brightness of 10,000 nits and a color gamut up to Rec. 2020. It uses Dolby's proprietary dynamic metadata defined in SMPTE ST 2094-10.

        Inputs and Outputs

        Audio

        • Analog Line Inputs: There are 3 pair of line inputs on both receivers for connecting sources with analog outputs.
