      6. Amplifier

      Denon AVR-S540BT Onkyo TX-NR709

      5 channel Amplifier: Denon AVR-S540BT features 5 channel power amplifier. It is rated at 70 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven).

      7 channel Amplifier: Onkyo TX-NR709 features 7 channel power amplifier. It is rated at 110 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven) and is able to drive 4 ohm speakers.
      • WRAT (Wide Range Amp Technology): Onkyo TX-NR709 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.
      • 3-Stage Inverted Darlington Circuitry: Onkyo TX-NR709 features 3-Stage Inverted Darlington Circuitry. Standard amplifiers employ a negative feedback (NFB) design that counters distortion by feeding back the opposite phase of the output signal into the input stage. Unfortunately, NFB is easily affected by inverse electromotive forces from the speakers, leading to an increase in circuit noise. Three-Stage Inverted Darlington Circuitry is a core Onkyo technology incorporating a low-NFB design that makes the sound more natural. Sensitive to oscillations, this circuitry requires very advanced control technology in order to be incorporated into the amplifier.

      THX™ Select™2 Plus certification

      Onkyo TX-NR709 is THX™ Select™2 Plus certified. This means that it is ideally suited for a room where the screen-to-seat viewing distance is approximately 3 to 4 meters, and the room size is approximately 56 cubic meters.

      7. Speaker Configurations

      Denon AVR-S540BT's and Onkyo TX-NR709's amplifiers can be assigned for different speaker configurations.

      • Configurations: Available configurations are:
      • Denon AVR-S540BT: 5.2 with internal amplifier.
      • Onkyo TX-NR709: 5.2, 7.2 with internal amplifier.
      • Front Wide Channel support: With the presence of two front wide speakers you can enhance the front surround stage. The following speaker configurations are available for front wide channels:
      • Denon AVR-S540BT: Does not support.
      • Onkyo TX-NR709: 7.2.
      • Bi-Amp: Onkyo TX-NR709 is able to bi-amp up to 2 main channels simultaneously. During bi-amplification two amplifiers are used for one speaker. One amplifier powers the midrange and tweeter section of the speaker and another amplifier powers the low frequency woofers. Each amplifier is less loaded and performs better. In order to use this feature speakers must have 2 pairs of connectors.

      8. Immersive Audio Formats

      Audyssey DSX

      Onkyo TX-NR709 supports Audyssey DSX which allows you to augment a standard five-channel home theater with either two Front Wide or two Front High speakers. The Wide channels create an expansive soundstage and bring out convincing directional effects. Alternatively, Height channels can add a vertical dimension to movie and game soundtracks.

      9. HDMI

      Denon AVR-S540BT comes with 5 HDMI inputs. It has 1 output.

      Onkyo TX-NR709 comes with 8 HDMI inputs. It has 2 outputs which work parallelly and output the same signal.

      • 4K/60Hz Passthrough on Denon AVR-S540BT: All inputs pass up to 4K 50/60Hz 4:4:4 video signal.
        1080/60p Passthrough on Onkyo TX-NR709: All inputs pass up to 1080p video signal.
      • 4K Upscaling on Onkyo TX-NR709: It can upscale up to 4K/30p (Marvell Qdeo) from HDMI and analog sources.
      • Analog To HDMI Upconversion: Onkyo TX-NR709 supports analog to HDMI Upconversion, so you can input your analog video sources and output them digitally via HDMI. This means that you will need only one HDMI cable to connect to your TV.
      • 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 Denon AVR-S540BT only).
      • HDCP 2.2 Copy Protection: Denon AVR-S540BT is HDCP 2.2 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)

      Denon AVR-S540BT supports HDR10, Dolby Vision and Hybrid Log-Gamma.

      Onkyo TX-NR709 does not support HDR. 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.
