All Power, No Frills

Get the features you need, without paying for the ones that you don’t, with the TX-SR373, a future-ready AV hub that delivers powerful reproduction of popular multichannel soundtracks, including DTS-HD Master Audio™ and Dolby® TrueHD, with surround calibration included. Discrete high-current amps love music: use Bluetooth® wireless technology to stream any music playing on your phone, tablet, or laptop in moments. The TX-SR373 allows you to connect your HDMI® equipped gear (DVD player, cable box/satellite TV receiver, streaming box, or game console) to the TV via one HDMI cable for a clutter-free installation. Easy to use and with heaps of muscle, the TX-SR373 is an affordable way to get theater sound at home.


Perfect Movie Soundtracks at Studio Resolution
The TX-SR373 is ready to decode Dolby® TrueHD and DTS-HD Master Audio™—the most popular lossless multichannel soundtrack formats common to Blu-ray Disc™. Experience authentic movie sound as the director intended.


Amp Power Adds Thrills to Music, Movies, Gaming, and TV Programs
Discrete analog amps (not an all-in-one integrated circuit) deliver high instantaneous current to the speakers for dynamic audio reproduction. Controlled power is the cornerstone of Onkyo’s amplification philosophy.



Easy Connection Guide Simplifies Setup

Connections to speakers and external devices are clearly labeled and illustrated on the rear panel—the connection diagram is readable upside down to make things easy when you’re leaning over the top of the receiver.
Supports 4K HDR and BT.2020 Video Pass-Through.

HDMI Connects You to the Future

Connect your players with just one cable linking to the TV for clean AV unit installation. HDMI terminals pass the latest video formats to your display, including those supporting 4K/60 Hz, HDR, BT.2020, and HDCP 2.2. There’s also an Audio Return Channel (ARC) for amplifying TV broadcasts. 


Bluetooth Wireless Technology
Bluetooth® wireless technology can stream whatever’s playing on your mobile device, laptop, or PC to the home theater. Use Onkyo-original Advanced Music Optimizer mode to enrich any compressed audio for a more satisfying musical experience.

(Streaming device not included)

Enjoy Music via USB Input
Connect a compatible USB memory device filled with MP3, WMA, or AAC audio files to enjoy clear and powerful reproduction of your music. Quality D/A conversion and a selection of DSP listening programs further enhance sound to suit different kinds of music.


AccuEQ Room Acoustic Calibration
AccuEQ sets essential speaker conditions such as distance, output, and crossover, and EQs for a clear and balanced audio image that’s free from distortion caused by the acoustics of your listening space.

Very good entry level receiver Review by Flippage
Been using this for a couple of weeks now. It does a great job with the sound, and the AccuEQ calibration works well.

Very happy with it overall. It's a great looking receiver, and has plenty of HDMI ports and lots of sound options.

Some of the options can be a bit confusing, but it may be more my lack of experience with AVR's than anything.

Definitely recommend this if you're looking at getting a receiver, and don't need anything expensive. I don't think I'd be able to tell the difference between this and a more expensive unit.

Note: I use Plex Media Player to serve media, so the AVR doesn't decode any audio. All the audio arrives in PCM and the AVR is set to Direct mode. (Posted on 28 August 2017)
