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-NR515 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.

Speaker Configurations

Onkyo TX-NR515's 7 channel amplifier can be assigned for different speaker configurations.

• Configurations: Available configurations are:
5.2, 7.2 with internal amplifier.
• 2-ch Bi-Amp: Onkyo TX-NR515 allows you 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: Onkyo TX-NR515 comes 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.
• Advanced Music Optimizer: Compressed music enhancement in 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-NR515 comes with Audyssey 2EQ room correction system and includes the calibration microphone.

• 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.

HDMI

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

• 1080/60p Passthrough: All inputs pass up to 1080p video signal.
• 4K Upscaling: Onkyo TX-NR515 can upscale up to 4K/30p (Marvell Qdeo) from HDMI and analog sources.
• Analog To HDMI Upconversion: The a/v receiver supports video upconversion, so you can connect your analog Component and Composite video sources and Onkyo TX-NR515 will output them via HDMI. This means that you will need only one HDMI cable to connect to your TV.
• HDCP 2.2 Copy Protection: All inputs and outputs are HDCP 2.2 compliant which is a requirement for 4K/HDR copy-protected content transmission.
• 3D Ready: Onkyo TX-NR515 is able to pass 3D video through HDMI.

Onkyo TX-NR515 offers multi-zone playback which allows you to play different input sources in 2 different rooms.

Zone 2

• Powered Zone 2: You can use the unit's 2 amplifier channels by connecting Zone 2 speakers directly to the speaker terminals. The remaining 5 channels will be left for main zone amplification.
• Audio Line Output: If you have a dedicated integrated amplifier for Zone 2 you can connect it to the a/v receiver via line outs by sending fixed signal and then control volume on the Zone 2 amplifier.

Audio

• Analog Line Inputs: There are 5 line inputs for analog audio connection.
• Digital Inputs and Outputs: 0 optical input, 2 optical outputs and 2 coaxial inputs are available for digital audio connection.
• Headphone Output: There is a 6.3 mm (1/4") headphone output jack on the front panel.

Video

• HDMI:
Inputs: 8 (1 front)   Outputs: 2 (simultaneous)
8K Inputs: 0
• Composite Video: Connect you VCR, Laserdisc player and other old video equipment with composite video cables.
Inputs: 5   Outputs: 1
• Component Video: Component video connection gives you the higher quality video compared to the composite video connection. So in case your old DVD player and other equipment do not have an HDMI output but have Component video output use this connection over the composite one. Onkyo TX-NR515 supports up to 1080p resolution on Component video connectors.
Inputs: 1   Outputs: 1
