[RESOLUTION & COMPATIBILITY] Supports up to 4K@60Hz (4:2:0) and 4K@30Hz (4:4:4). If your source device does not output 4K@60Hz (4:2:0), lower the resolution to 4K@30Hz or 1080P for proper signal processing. Compatible with HDMI 1.4 and HDCP 1.4. Note: Does not support eARC.
[DUAL AUDIO EXTRACTION] Extracts audio from an incoming HDMI signal and routes it to an external sound system via Analog RCA and/or Optical (SPDIF) outputs. Important Note on RCA: Analog RCA outputs support standard 2CH PCM stereo only (does not downmix 5.1Ch to RCA) and do not support TV remote volume/CEC control.
[ARC AUDIO EXTRACTION & ROUTING] Takes audio from a smart display via HDMI ARC and routes it strictly through the Optical port to external audio systems. Please note: ARC mode requires manual engagement via the physical button on the unit, and settings must be re-applied if power is completely disconnected.
[DIRECT CONNECTION & COMPATIBILITY] Designed for straightforward point-to-point setups
