    5. Amplifier

    7 channel Amplifier

    Onkyo TX-NR545 features 7 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-NR545 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.

    8. HDMI

    Onkyo TX-NR545 features 6 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-NR545 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: 3 inputs and 1 output are HDCP 2.2 compliant which is a requirement for 4K/HDR copy-protected content transmission.
    • 3D Ready: Onkyo TX-NR545 is able to pass 3D video through HDMI.
    andh3>HDR (High Dynamic Range)

    Onkyo TX-NR545 supports HDR (high dynamic range) video formats such as HDR10 via HDMI ports. 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.

    9. Room Calibration

    Onkyo TX-NR545 comes with AccuEQ Advance 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.

    10. Multi-zone Playback

    Onkyo TX-NR545 offers multi-zone playback which allows you to play different input sources in 2 different rooms.


    Zone 2

    • Powered Zone 2: You can use the unit's 2 amplifier channels by connecting Zone 2 speakers directly to the speaker terminals. The remaining 5 channels will be left for main zone amplification.
    • Audio Line Output: If you have a dedicated integrated amplifier for Zone 2 you can connect it to the a/v receiver via line outs by sending fixed signal and then control volume on the Zone 2 amplifier.
