Selected Features

Amplifier

Denon AVR-X540BT has 5 channel and Onkyo TX-NR515 has 7 channel amplifiers. Denon AVR-X540BT delivers 70 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven) and Onkyo TX-NR515 delivers 80 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven)


Video Features

Denon AVR-X540BT supports 4K passthrough up to 60p and Onkyo TX-NR515 supports 1080p passthrough. Onkyo TX-NR515 can do 4K upscaling up to 30p. Denon AVR-X540BT supports HDR10.


HDR10

High-dynamic-range (HDR) video has greater dynamic range than standard-dynamic-range (SDR) video with brigter whites and deeper blacks. HDR10 was announced on August 27, 2015, by the Consumer Technology Association and uses the wide-gamut Rec. 2020 color space. It sends static metadata via video stream to the TV which calibrates its screen brightness and color according to that. HDR10 supports up to 1000 nits of brightness and 10-bit color which corresponds to 1024 shades of the primary RGB colors.


WRAT

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.


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.
