48Gbps 4x1 Switcher with ARC/eARC Function

The 48Gbps 4x1 HDMI Switcher is a high-performance device designed to route up to four HDMI source signals to a single high-definition display (p. 3). It is fully compliant with HDMI 2.1 and HDCP 2.3 standards, supporting a massive video bandwidth that ensures compatibility with the latest technology (pp. 3-4). Users can enjoy ultra-high resolutions up to 8K@60Hz or 4K@120Hz, along with advanced features like VRR, ALLM, and various HDR formats, including Dolby Vision and HDR10+ (pp. 3-4).

A standout feature of this HDMI Switcher is its comprehensive audio management, which includes ARC/eARC functionality (pp. 1, 3). It can de-embed audio from both HDMI inputs and TV return signals, outputting high-quality sound through dedicated optical (S/PDIF) and analog (L/R) ports (pp. 3, 7). The device supports a wide array of premium audio formats such as Dolby Atmos, DTS:X, and LPCM 7.1CH, and it is specifically designed to work seamlessly with eARC sound systems like Sonos ARC & Beam (pp. 3-4).

Encased in a sturdy black metal enclosure, the HDMI Switcher is built for both durability and ease of use (p. 5). Users can switch between sources using a front-panel button or the included IR remote, and the device also features an auto-switching mode for hands-free operation (pp. 6-7). For technical optimization, it includes an integrated EDID DIP switch that allows for manual control over audio and video configurations, ensuring maximum compatibility between various source devices and displays.
