RS-HD2HDA-8K 8K Compatible HDMI Audio Extractor 4K120Hz VRR Support Used with PS5. I bought this to try because I didn't like the low volume when using a USB-connected DAC/DDC with the PS5. I was using the optical digital output, but the volume didn't decrease, and connecting to the DAC via this method resulted in higher sound quality than USB connection. There was no delay or image quality degradation, and the operation was stable. I think it's rare to find a product that supports 4K120Hz VRR and has an optical digital output, and furthermore, operates stably. - Model: HDMI AUDIO EXTRACTOR 8K - Output Terminals: HDMI, RCA (red/white), Optical Digital - Manufacturer: RATOC Systems, Inc. - Accessories: HDMI cable - Color: Black Thank you for viewing.
