TX-SR393DAB: 5.2ch AV Receiver with Dolby Atmos and DTS:X

Experience Dolby Atmos and DTS:X sound at home with the TX-SR393DAB. Choose a speaker layout that suits your room, whether it’s a space-saving 2.1-channel setup enhanced with 3D surround sound courtesy of Dolby Atmos or DTS Virtual:X, or a 3.2.2-channel system for native object-based audio playback. However you play, dynamic power is ready to thrill you with authentic high-current analog amps backed by a high-efficiency power supply.

Ready for 4K HDR Entertainment

Enjoy full support for 4K/60p and HDR (High Dynamic Range) video formats such as HDR10, HLG, Dolby Vision, and BT.2020, including support for 4:4:4 sub-sampling. Four HDMI ports and ARC-ready output enable you to pass video from your player to a compatible TV, allowing you to enjoy everything that recent movies and games have to offer. The OSD dialog window lets you easily check the status of A/V inputs and outputs.

Enhanced Spatial Sound with DTS Virtual:X

DTS Virtual:X technology delivers an immersive 3D surround sound experience from any speaker configuration, whether 2.1, 3.1, or 5.1 setups. This innovation doesn’t require the installation of surround or rear speakers, instead using sophisticated DSP algorithms to create a multidimensional sound field with impressive surround height and spatiality. Whether you’re in a large or small space, this technology’s performance is equally convincing. Importantly, DTS Virtual:X is compatible with DTS:X soundtracks, DTS formats, and unencrypted stereo, thus operating in the 3D domain.

Enhance Dialogue at the Touch of a Button

The TX-SR393DAB amplifier is the ideal solution for quickly and effectively resolving inaudible dialogue issues in TV programs and movies. It features a DSP-controlled Vocal Enhancer Function capable of identifying vocal frequencies and boosting or lowering them as needed. This function is accessible via remote control keys or tone controls on the receiver’s front panel. With this innovation, you can finally enjoy clear, audible sound without missing any important information.

AccuEQ Calibration with Subwoofer Volume Calibration and AccuReflex Technology

Sound adjustment with AccuEQ creates a harmonious sonic experience in your space. By detecting each speaker’s size, distance, and position, AccuEQ adjusts sound pressure levels to ensure balanced sound. It also selects the optimal crossover filter for the subwoofer and equalizes all speakers for optimal sound quality. AccuReflex technology optimizes sound reproduction based on object movement thanks to Dolby Atmos compatibility. It corrects phase mismatches between directional and non-directional sounds for enhanced localization. With this technology, you can enjoy a 3D sound field with vertical movement and a new height dimension.
