Positioned as an ‘ideal starter component’, the newly announced Onkyo TX-SR383 ($399 USD and $499 CAD) available later this month, will include discrete high-current 7-channel analog amplification, plus a host of ‘world-class’ features. While it provides native 7.2-channel reproduction, it can also support a 5.2-channel surround sound configuration with powered audio to a pair of Zone 2 stereo speakers.
The unit is claimed to be a ‘future-ready’ hub for connecting HDR-ready media players and displays, and features four HDMI inputs and one output supporting 4K/60p, HDR10, HLG, 4:4:4 color space, and BT2020 color-standard video pass-through, as well as HDCP 2.2. The HDMI output also includes ARC (Audio Return Channel) for ARC-ready displays.
With 155W/ch (6 ohms, 1 kHz, 10% THD, 1 channel driven) and supporting DTS-HD Master Audio™ and Dolby® TrueHD movie soundtracks – with either Surround Back or Front Height speakers to enhance theater-grade immersion – the easy-to-use TX-SR383 is clearly suited for 4K source material.
With plug-in microphone and screen-prompted AccuEQ Room Acoustic Calibration, surround audio can be tailored to any room, and of course speaker parameters are measured in the customary way for such an in-built system i.e. distance, output level, crossover and EQs. Bluetooth® Version 3.0 wireless technology supports the AAC codec for high-quality audio transmission, while compliance with Qualcomm® aptX™ audio enables CD-like music playback with compatible smartphones, tablets, and personal computers. Audio can be streamed with pairing via a key on the front panel or remote controller.
Onkyo claims its own DSP algorithm Music Optimizer improves audio playback with compressed files, and the TX SR-383 includes a 5V/1A USB outlet to power devices that require it, enabling ‘premium’ sound with subscription services and streamed media. Furthermore, legacy devices can be connected via composite video and optical/coaxial digital audio inputs.
Quite a feature-rich box for the money then, and a good entry point for newcomers to the home theater world. But note that while there is a generous two line-level sub output, there is no immersive audio included in the form of Dolby Atmos or DTS:X.
