      Audio Section

      Amplifier

      Onkyo TX-NR525 Onkyo TX-NR515

      5 channel Amplifier: Onkyo TX-NR525 features 5 channel power amplifier. It is rated at 80 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven).

      7 channel Amplifier: Onkyo TX-NR515 features 7 channel power amplifier. It is rated at 80 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven).
      • WRAT (Wide Range Amp Technology): Onkyo TX-NR525 and Onkyo TX-NR515 feature 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.

      Speaker Configurations

      Onkyo TX-NR525's and Onkyo TX-NR515's amplifiers can be assigned for different speaker configurations.

      • Configurations: Available configurations are:
      • Onkyo TX-NR525: 5.2 with internal amplifier.
      • Onkyo TX-NR515: 5.2, 7.2 with internal amplifier.
      • Bi-Amp: Onkyo TX-NR515 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.

        • Sound Processing

        • Audyssey: Both receivers come with Audyssey Dynamic EQ and Dynamic Volume.
        • Dynamic EQ: selects the best possible frequency response and surround volume levels moment-by-moment. This ensures that the bass response, tonal balance and surround impression remain constant despite changes in volume. This is the first technology that carefully combines information from incoming source levels with actual output sound levels in the room, a pre-requisite for delivering a dynamic volume solution.
        • Dynamic Volume: Your Listening experience can be greatly diminished when there are significant shifts in volume between television programs, commercials and within the program material itself. When this happens you must constantly adjust the volume to maintain your desired listening level. Audyssey Dynamic Volume monitors the volume of program material moment-by-moment and automatically adjusts it, maintaining the desired listening level for all content while optimizing the dynamic range to preserve impact.
        • Compressed Music Enhancer: Onkyo TX-NR525 and Onkyo TX-NR515 feature Compressed Music Enhancer which enhances the quality of the music files with lossy compression.
        • Advanced Music Optimizer: Compressed music enhancement in Onkyo TX-NR525 and Onkyo TX-NR515 is done by Onkyo’s Advanced Music Optimizer. While MP3 or AAC files may sound fine through the headphones of your portable digital player, the limitations of these files can be exposed when played back through a quality home entertainment system. This is because a significant amount of high-frequency bit information is lost during the file-compression process. To counter this, Onkyo has designed the Advanced Music Optimizer to compensate for lost bit information and improve the quality of compressed audio signals. This results in a clearer and more expansive sound. Also included in this technology is a loudness correction feature that further improves the audio character of compressed files.

        Room Calibration

        Onkyo TX-NR525 comes with Audyssey MultEQ and Onkyo TX-NR515 comes with Audyssey 2EQ room correction system.

        • Audyssey Room Calibration: Audyssey is an acoustic measurement technology which automatically restores the acoustic distortion caused by the acoustic behaviour of a room with only a push on a button. Audyssey equalization provides an clear, accurate, natural sound with voices and dialog that become focused and intelligible, restoring the musical balance. Musical instruments and sound effects become precisely localized and the surround soundstage is made seamless and enveloping.

      Video Section

      HDMI

      Onkyo TX-NR525 comes with 6 HDMI inputs. It has 1 output.

      Onkyo TX-NR515 comes with 8 HDMI inputs. It has 2 outputs which work parallelly and output the same signal.

      • 4K/30Hz Passthrough on Onkyo TX-NR525: All inputs pass up to 4K/30p video signal.
        1080/60p Passthrough on Onkyo TX-NR515: All inputs pass up to 1080p video signal.
      • 4K Upscaling on Onkyo TX-NR515: It can upscale up to 4K/30p (Marvell Qdeo) from HDMI and analog sources.
      • Analog To HDMI Upconversion: Onkyo TX-NR515 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.
      • HDCP 2.2.0 Copy Protection: Both receivers are HDCP 2.2.0 compliant which is a requirement for 4K/HDR copy-protected content transmission.
      • 3D Ready: Both receivers are able to pass 3D video through HDMI.

      Inputs and Outputs

      Audio

      • Analog Line Inputs: There are 6 pair of line inputs on Onkyo TX-NR525 and 5 pair of line inputs on Onkyo TX-NR515 for connecting sources with analog outputs.
