The unit also includes Bluetooth capability allowing wireless streaming from compatible devices such as smartphones or tablets while its audio return channel (ARC) allows users to send audio signals back through their TV’s HDMI connection for enhanced sound quality when watching movies or shows on Netflix etc. Ultimately, two subwoofer outputs provide extra low frequency power giving more depth in bass response which is perfect if you have large speakers that need some extra oomph!

The Onkyo TX-NR555 offers excellent audio quality, with a signal-to-noise ratio of 106 dB and total harmonic distortion of 0.08%. It has an extraordinary frequency response range from 20 Hz to 20 kHz, allowing for accurate sound reproduction across the entire spectrum.

Along with that, it supports all major digital music formats such as AAC, AIFF Apple Lossless FLAC MP3 and WAV files so you can enjoy your favorite tunes in high fidelity without any loss in sound quality. Moreover, its 32bit/384kHz Audio D/A converter ensures that every detail is accurately reproduced when playing back content through this device.
Number Of Channels
The Onkyo TX-NR555 is a 7.2 channel AV receiver, offering seven channels of amplification for surround sound systems and two subwoofer outputs to provide extra bass power. Each of the main channels can output up to 140 watts per channel at 6 ohms or 80 watts per channel at 8 ohms, while each subwoofer output provides an additional 560 total wattage with 0.08% Total Harmonic Distortion (THD). This enables users to create powerful home theater experiences that are sure to impress any audience.
Setup Ease
The Onkyo TX-NR555 is designed for easy setup. It has a total output power of 560 W, with 140 W and 80 W per channel respectively.

Moreover, it supports upscaling via HDMI up to 4K resolution as well as 3D pass-through technology so that you can enjoy the latest content in high definition quality on your TV screen. However, this device comes equipped with dual zone capability which allows two separate audio sources (such as an AV Receiver) connected simultaneously while still being able to control both independently from one remote controller - making it ideal for multiroom setups! Eventually, its Smartphone Remote Control feature makes controlling the system even easier by enabling users access all settings directly from their phones or tablets through Wi-Fi connection.
