About

Pay for the features you need and none 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.

Connect all your gear (from network players to vintage consoles) to the TV via one HDMI® cable for a clutter-free install. Easy to use and with heaps of muscle, the TX-SR373 is an affordable way to get cinema sound at home.

Product Features

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

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. 

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

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.

Bluetooth® Wireless Technology 

• Bluetooth® wireless technology can stream whatever’s playing on your mobile device, laptop, or PC to the home cinema. 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 the sound to suit different kinds of music. 

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.
