Power Handling

This home theater receiver has a power output of 80 watts per channel when using 8-ohm speakers, and about 100 watts for 6-ohm speakers. The output on one channel for a 6-ohm speaker is 170 watts, and the total power consumption is 560 watts. In other words, the amplifiers in this receiver are easily capable of powering seven speakers. The two subwoofer pre-outs mean you can also add a lot of foundation-rumbling bass to the mix.

The TX-NR575 has a total harmonic distortion of .08 percent. This is one of the lowest ratings among receivers we reviewed, which means you'll listen to clean, undistorted audio. It also has a signal-to-noise ratio of 106 dB, which is the best ratio we've seen in these units. Not many manufacturers include these power-handling ratings with their specifications, because they often don’t reflect well on the receiver. So when you see ratings like this, it’s a good sign. Onkyo receivers are known for good audio quality, and the TX-NR575 is no exception. It scored well in several published listening tests.

Audio Formats

The TX-NR575 has some but not all of the audio decoders that are critically important in giving you the best surround sound system possible. Like all receivers at this price point, it has the Dolby TrueHD and DTS-HD decoders, which are the most common high-definition soundtrack formats for Blu-ray movies. This is the format that most movies are mixed to. It also includes the Dolby Atmos and DTS:X decoders, which are newer and less common but likely to become more popular. These decoders have overhead channels that add more depth the soundtrack – when Superman flies over the heads of onlookers, it’ll sound like he’s flying over your head as well.

However, this home theater receiver lacks other audio formats. Most notably, it only has one upmixing decoder – DTS:Neural:X. These are necessary for converting stereo signals from standard sources like TV or video games to a surround sound signal.


The connectivity options of the Onkyo TX-NR575 are excellent. Like most AV receivers around $500, it has a bevy of wireless options – Wi-Fi, Bluetooth, AirPlay, DLNA. These all allow you to stream music and video directly from your mobile devices. You can play music from any of your favorite internet radio stations. One of the best things about this receiver is that it automatically switches to the correct input when you connect to it via Bluetooth.

This being a 7.2 surround sound receiver, you can connect seven speakers to it – front center, front left, front right, middle left, middle right, back surround left and back surround right. You can use two of those speakers for the overhead speakers if you’re watching movies with Dolby Atmos or DTS:X. The 0.2 part of the channel is the pre-outs for two subwoofers, which are self-powered. This means that it sends the low frequencies to your subwoofers, but the subs need to be self-powered, which is usually the case.

It has six HDMI inputs, allowing you to plug in a host of devices – your cable, satellite, gaming console, online media streaming device and more. Then you can simply connect the receiver to the television using a single connection.

It also has two optical outputs, which allow you to connect it to an older television that does not have HDMI ports. One of the rarest features of this receiver is its phonograph input. If you're a vinyl aficionado, you can connect your turntable to the TX-NR575 and listen to music over your surround sound speakers.
