      6. Amplifier

      Onkyo TX-RZ900 Sony STR-AN1000

      7 channel Amplifier: Onkyo TX-RZ900 features 7 channel power amplifier. It is rated at 140 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven) and is able to drive 4 ohm speakers.

      7 channel Amplifier: Sony STR-AN1000 features 7 channel power amplifier. It is rated at 100 W (6 Ω, 20 Hz - 20 kHz, 2 channel driven).
      • WRAT (Wide Range Amp Technology): Onkyo TX-RZ900 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: Onkyo TX-RZ900 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-RZ900 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.

      8. Immersive Audio Formats

      Dolby Atmos

      Onkyo TX-RZ900 and Sony STR-AN1000 support Dolby Atmos.

      • Dolby Surround Upmixer: Both models support 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: Sony STR-AN1000 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

      Onkyo TX-RZ900 and Sony STR-AN1000 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: Onkyo TX-RZ900 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: Onkyo TX-RZ900 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.

      IMAX Enhanced

      Sony STR-AN1000 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.

      Sony STR-AN1000 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

      Sony STR-AN1000 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-RZ900 with built-in phono stage for connecting the moving magnet cartridge output of the turntable directly to the receiver.
      • Analog Pre-Outs: Onkyo TX-RZ900 has 7.2 preamplifier outputs which allows you to connect the receiver to the external power amplifier. 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, Sony STR-AN1000 has 8 channel processing but has only 7 channel amplifier, so it needs external amplifier connected to the analog pre-outs in order to reach its maximum speaker configuration.
      • Analog Line Inputs and Outputs: There are 8 pair of line inputs on Onkyo TX-RZ900 and 4 pair of line inputs on Sony STR-AN1000 for connecting sources with analog outputs. There is also 1 pair of line outputs on Onkyo TX-RZ900.
      • Digital Inputs: 3 optical inputs and 2 coaxial inputs are available on Onkyo TX-RZ900 and 1 optical input and 1 coaxial input are available on Sony STR-AN1000 for digital audio connections.
      • Headphone Output: There is a 6.3 mm (1/4") headphone output jack on the front panel of each receiver.
