      6. Amplifier

      Arcam AVR31 Onkyo TX-RZ830

      7 channel Class G Amplifier: Arcam AVR31 features 7 channel power amplifier with Class G design. It is rated at 120 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven) and is able to drive 4 ohm speakers.

      9 channel Amplifier: Onkyo TX-RZ830 features 9 channel power amplifier. It is rated at 120 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven) and is able to drive 4 ohm speakers.
      • Dynamic Audio Amplification: Onkyo TX-RZ830 features Dynamic Audio Amplification which is Onkyo’s amplification philosophy that focuses on capturing the energy and dynamism contained in the audio signal and reproducing it without loss. Audio signals are not static like a test tone, but rather a countless collection of constantly moving waves. While static measurements such as S/N ratio and Total Harmonic Distortion are important, Onkyo believes that excellent dynamic and transient response is the key to emotionally involving sound. Dynamism - the “life” in music - is achieved when the amp can respond to changes in the signal instantaneously, so notes start and stop naturally and the nuances in attack, decay, sustain, and release are voiced with conviction. Onkyo home theater receivers represent the culmination of almost 70 years’ experience in amplifier design. The unique elements of their amplification system comprise high-current, low-impedance architecture to accurately control large speaker cones while enabling instantaneous response to dynamic changes, and discrete wide-range amplifier circuit topology to eliminate phase shift for clear and accurate audio imaging.
      • Toroidal Transformer: Arcam AVR31 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™ (previously known as Select2) certification

      Onkyo TX-RZ830 is THX™ Select™ (previously known as Select2) certified. This means that it is for medium sized rooms, up to 2,000 cubic feet in size, with a 10-12 foot viewing distance from the screen.

      • Onkyo TX-RZ830: 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.

      8. Immersive Audio Formats

      Dolby Atmos

      Arcam AVR31 and Onkyo TX-RZ830 support Dolby Atmos.

      • Dolby Surround Upmixer: Both models support Dolby Surround Upmixer.

The upmixer has replaced the Dolby Pro Logic II family with improved upmixing algorithms.
      • Dolby Atmos Height Virtualization: Arcam AVR31 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 AVR31 and Onkyo TX-RZ830 support DTS:X.

      • DTS Neural:X: Both models feature 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 AVR31 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: Both models have 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.

The result is greater contrast and more details in dark and bright areas, better color and depth.


      Enhanced Audio Return Channel (eARC)

      Arcam AVR31 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 AVR31 supports Auto Low Latency Mode (ALLM) and Variable Refresh Rate (VRR) for lag-free and smooth gaming.

      10. Inputs and Outputs

      Audio

      • Phono Input: There is an MM phono input on Onkyo TX-RZ830 with built-in phono stage for connecting the moving magnet cartridge output of the turntable directly to the receiver.
      • Analog Pre-Outs: Arcam AVR31 has 15.2 and Onkyo TX-RZ830 has 11.2 preamplifier outputs which allow you to connect the receivers to the external power amplifiers. You may want to use a high quality external amplifier for certain channels, usually for front L/R and center, and use the receiver to power the rest. Also, Arcam AVR31 has 15 channel processing but has only 7 channel amplifier and Onkyo TX-RZ830 has 11 channel processing but has only 7 channel amplifier, so they need external amplifiers connected to their analog pre-outs in order to reach their maximum speaker configurations.
      • Analog Line Inputs and Outputs: There are 7 pair of line inputs on Arcam AVR31 and 6 pair of line inputs on Onkyo TX-RZ830 for connecting sources with analog outputs. There is also 1 pair of line outputs on Arcam AVR31.
      • Digital Inputs and Outputs: 2 optical inputs, 1 optical output and 4 coaxial inputs are available on Arcam AVR31 and 2 optical inputs and 1 coaxial input are available on Onkyo TX-RZ830 for digital audio connections.
      • Headphone Output: There is a 3.5 mm (1/8") headphone output jack on the front panel of each receiver.
