Product Description

Onkyo TX-SR373 5.2-Channel HDR Compatible A/V Home Theatre Receiver

The Onkyo TX-SR373 decodes 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.

The Onkyo TX-SR373 doesn’t include an ethernet connection or WiFi, but that doesn’t mean you can’t send your music to it wirelessly. The receiver includes Bluetooth with aptX. This allows you to easily sync your phone or smart device with the unit and stream audio to the amp without a wired connection.

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/60Hz, HDR, BT.202, and HDCP 2.2. There’s also an Audio Return Channel for amplifying TV broadcasts.

Add 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. This gives the TX-SR373 155W/ch (6 ohms, 1kHz, 10% THD, 1 channel driven) 80W/Ch (8 ohms, 20Hz–20kHz, 0.08% THD, 2 channels driven, FTC).

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.

Bluetooth Wireless Technology Featuring Qualcomm aptX Audio

Bluetooth wireless technology mirrors whatever’s playing on your mobile device, laptop, or PC on the home theater. Devices supporting Qualcomm aptX codec deliver virtually lossless low-latency playback, while original Advanced Music Optimizer mode enriches any compressed audio for a more satisfying musical experience.

Room Calibration Made Easy

AccuEQ measures and corrects speaker distances, output levels, crossover frequencies, and frequency response from one quick and easy listening position to ensure clear and balanced surround-sound.

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.
