The Onkyo TX-SR383 is the company's first AV receiver to be introduced in 2018. With a list price of $399 ($499 Canadian), it's in the "entry-level" category, but it offers several features that reach beyond that classification.

This AVR provides seven channels of amplification rated at 80 watts per channel (8 ohms, 20 Hz-20 kHz, 0.08% THD, two channels driven) or 155 W/ch (6 ohms, 1 kHz, 10% THD, one channel driven) plus two line-level subwoofer outputs. In addition to 7.2 operation with back-surround or front-height speakers, it can power a 5.2 system as well as a pair of speakers in another room. It fully supports Dolby TrueHD and DTS-HD Master Audio, but not Dolby Atmos or other immersive-audio formats.

Other audio features include a multichannel 192 kHz/24-bit DAC (digital-to-analog converter) and support for 2-channel, 2.8 MHz SACD/DSD content. Also, a direct mode bypasses all processing for high-fidelity 2-channel listening.

The front LR speaker outputs are binding posts, while the other speaker outputs are spring clips. Other inputs include two digital-audio inputs (one coax, one optical), three analog-audio inputs, one headphone output, two composite-video inputs, one composite-video monitor output, one USB port with 5V/1A power, and AM/FM antenna inputs.

On the video side, the Onkyo TX-SR383 offers four HDMI 2.0 inputs and one HDMI 2.0 output that support 4K/60p, 4:4:4 color, HDR10 and HLG high dynamic-range formats (not Dolby Vision), and the BT.2020 color standard. The HDMI output also supports ARC (Audio Return Channel) from the TV's tuner and streaming apps. In addition, the unit passes HDMI data when it's in standby mode.

Onkyo's AccuEQ room correction automatically sets speaker distance, level, crossovers, and EQ using the included setup microphone. The TX-SR383 also supports Bluetooth 3.0 wireless audio with the AAC, MP3, WMA, and aptX codecs. The company's Music Optimizer DSP algorithm is said to restore information lost in compressed digital files received via Bluetooth or the AVR's USB input.
