    Audio Section

    5 channel Amplifier

    Onkyo TX-SR343 features 5 channel power amplifier. It is rated at 65 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven).

    • WRAT (Wide Range Amp Technology): Onkyo TX-SR343 features Onkyo’s Wide Range Amp Technology (WRAT) circuit layout that prevents phase shifting by pushing the roll-off point higher than the listening-level frequency. Amplifying sound without phase shift creates an uncommonly well-focused and realistic audio image. If phase shift occurs and signal timing is not accurate, then neither is the resulting audio image.

    Sound Processing

    • Advanced Music Optimizer: Compressed music enhancement in Onkyo TX-SR343 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.

    Video Section

    HDMI

    Onkyo TX-SR343 features 4 HDMI inputs. It has 1 output.

    • 4K/60Hz Passthrough: All inputs pass up to 4K/60p (RGB/YCbCr4:4:4/YCbCr4:2:2, 24 bit) video signal.
    • Analog To HDMI Upconversion: The a/v receiver supports video upconversion, so you can connect your analog Component and Composite video sources and Onkyo TX-SR343 will output them via HDMI. This means that you will need only one HDMI cable to connect to your TV.
    • 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-SR343 is able to pass 3D video through HDMI.
