Selected Features
Amplifier
Denon AVR-X540BT has 5 channel and Onkyo TX-NR626 has 7 channel amplifiers. Denon AVR-X540BT delivers 70 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven) and Onkyo TX-NR626 delivers 95 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven)
Video Features
Denon AVR-X540BT supports 4K passthrough up to 60p and Onkyo TX-NR626 supports 4K passthrough up to 30p. Onkyo TX-NR626 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-NR626 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-NR626 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.
Phase-Matching Bass Boost
Onkyo TX-NR626 features Phase-Matching Bass Boost. The negative effects of phase-shift or the timing difference between sound waves of different frequencies can sometimes be heard in audio players when corners are cut in order to increase bass response. While most audio systems have some form of low-frequency enhancement system, often a bigger bass sound comes at the expense of mid-range clarity, and results in a smeared or muddy sound. Onkyo’s Phase-Matching Bass Boost technology avoids this problem by improving the phase timing to preserve the natural clarity of the mid-range allowing vocals and strings to shine while maintaining a smooth, powerful bass response at all volume levels.
