Arcam AVR21	Onkyo TX-NR727
7 channel Class A/B Amplifier: Arcam AVR21 features 7 channel power amplifier with Class A/B design. It is rated at 110 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven) and is able to drive 4 ohm speakers.	7 channel Amplifier: Onkyo TX-NR727 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-NR727 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.
• Toroidal Transformer: Arcam AVR21 has a toroidal transformer which in general costs several times more than a regular C-core transformer and radiates less electromagnetic noise outside its donut shaped core.

THX™ Select™2 Plus certification

Onkyo TX-NR727 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.

Arcam AVR21's and Onkyo TX-NR727's amplifiers can be assigned for different speaker configurations.

• Dolby Atmos Configurations: The following speaker configurations are supported for Dolby Atmos:
Arcam AVR21: 5.2.2 with internal amplifier and 5.2.4, 7.2.2 with addition of external 2 channel amplifier and 5.2.6, 7.2.4, 9.2.2 with addition of external 4 channel amplifier and 7.2.6, 9.2.4 with addition of external 6 channel amplifier and 9.2.6 with addition of external 8 channel amplifier.
Onkyo TX-NR727: Not supported.
• DTS:X Configurations: The following speaker configurations are supported for DTS:X:
Arcam AVR21: This model supports DTS:X but not DTS:X Pro. Since DTS:X is limited with 11 channel processing some of the speaker configurations for Dolby Atmos are not supported here. The supported configurations are 5.2.2 with internal amplifier and 5.2.4, 7.2.2 with addition of external 2 channel amplifier and 5.2.6, 7.2.4, 9.2.2 with addition of external 4 channel amplifier.
Onkyo TX-NR727: Not supported.
• Configurations without height channels: There are also other speaker configurations available which do not include height channels:
Arcam AVR21: 5.2, 7.2 with internal amplifier and 9.2 with addition of external 2 channel amplifier.
Onkyo TX-NR727: 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:
Arcam AVR21: 9.2, 9.2.2, 9.2.4, 9.2.6.
Onkyo TX-NR727: Does not support.
• 2-ch Bi-Amp: Both models are 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.

Dolby Atmos

Arcam AVR21 supports Dolby Atmos.

• Dolby Surround Upmixer: Arcam AVR21 supports Dolby Surround Upmixer. If the content is not mixed in Dolby Atmos then the Dolby surround upmixer will expand the audio to all channels including ceiling speakers. The upmixer has replaced the Dolby Pro Logic II family with improved upmixing algorithms.
• Dolby Atmos Height Virtualization: Arcam AVR21 supports Dolby Atmos Height Virtualization which is a digital signal processing solution that leverages Dolby's deep understanding of human audio perception to create the sensation of overhead sound from the listener-level speakers.

DTS:X

Arcam AVR21 supports DTS:X.

• DTS Neural:X: Arcam AVR21 supports DTS Neural:X which is an advanced upmixer that can take non DTS:X content and upmix it to the DTS:X speaker layout. It has replaced the DTS Neo family with improved flexibility.
• DTS Virtual:X: Arcam AVR21 supports DTS Virtual:X which bridges the gap between DTS:X codec and the reality of so many consumers' homes, allowing you to enjoy multi-dimensional sound regardless of room size, layout, or speaker configuration. If you have a limited speaker setup you will miss a full immersive potential of your entertainment system. DTS Virtual:X adds height and surround audio effect to your system without adding height speakers. It works with multiple configurations and delivers immersive sound experience out of 5.1 or even 2.1 speaker layouts.
• DTS Dialog Control: Arcam AVR21 supports DTS Dialog Control. This function adjusts the dialog levels during playback of the DTS:X stream. It allows you to separately increase the dialog levels in contrast with the background sound and hear dialog easily even under noisy circumstances.

Auro-3D

Arcam AVR21 supports Auro-3D.

• Auro-Matic upmixer: Auro-Matic upmixer takes non Auro-3D sound and upmixes to the current speaker configuration.

Audyssey DSX

Onkyo TX-NR727 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.

IMAX Enhanced

Arcam AVR21 is IMAX Enhanced certified. To qualify for IMAX Enhanced certification, 4K HDR televisions, projectors, sound bars, a/v receivers, loudspeakers, powered subwoofers and other premium home entertainment devices must meet carefully prescribed performance requirements established by IMAX, DTS and Hollywood's leading experts.

• What makes an IMAX Enhanced A/V receiver different from an A/V receiver with DTS:X technology? DTS:X technology is commonly found in most multi-channel A/V receivers on the market today. All IMAX Enhanced A/V receivers include DTS:X technology and deliver additional features, such as auto-sensing of IMAX Enhanced content, via IMAX Mode. IMAX Mode indicates that your A/V receiver supports fully immersive IMAX signature sound.

Arcam AVR21 comes with 7 HDMI 2.1 inputs with 8K support. It has 3 outputs - 2 x 8K for MAIN and 1 x 4K for ZONE2.

Onkyo TX-NR727 comes with 8 HDMI inputs. It has 2 outputs which work parallelly and output the same signal.

• 8K/60Hz and 4K/120Hz Passthrough on Arcam AVR21: All inputs pass up to 8K 50/60Hz and 4K 100/120Hz 4:4:4 video signal.
  4K/30Hz Passthrough on Onkyo TX-NR727: All inputs pass up to 4K/30p video signal.
• 4K Upscaling on Onkyo TX-NR727: It can upscale up to 4K/30p (Marvell Qdeo) from HDMI and analog sources.
• Analog To HDMI Upconversion: Onkyo TX-NR727 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 Arcam AVR21 only).
• HDCP Copy Protection: Arcam AVR21 is HDCP 2.3 and Onkyo TX-NR727 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)

Arcam AVR21 supports HDR10, HDR10+, Dolby Vision and Hybrid Log-Gamma.

Onkyo TX-NR727 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.

Enhanced Audio Return Channel (eARC)

Arcam AVR21 supports Audio Return Channel (ARC) which allows the compatible TV to send audio signal to the a/v receiver through the same HDMI cable which is used to send audio and video signals to the TV. So one HDMI cable is used to transfer audio signal in both directions. New Enhanced ARC will support uncompressed audio formats such as Dolby Atmos, DTS:X, Dolby TrueHD and DTS HD Master Audio whereas the previous ARC could support only Dolby Digital, Dolby Digital Plus, DTS, DTS HD, and PCM.

Gaming Features

Arcam AVR21 supports Auto Low Latency Mode (ALLM) and Variable Refresh Rate (VRR) for lag-free and smooth gaming.
