The JTECH-8KSW21AE offers three methods for switching between HDMI inputs:
- Manual Switching: Press the "SELECT" button on the front panel of the switch to cycle between Input 1 and Input 2. The corresponding LED will illuminate.
- Remote Control: Use the included remote control to directly select Input 1 or Input 2, or use the "Select" button on the remote.
- Auto Switching: The switch can automatically detect and switch to a newly active HDMI source. If both inputs are active, it will remain on the currently selected input until one is powered off or disconnected.

Audio Extraction:
The switch can extract audio from the HDMI signal and output it via the Optical (SPDIF) or 3.5mm analog ports. This allows you to send audio to external sound systems independently of your display's audio.
- Supports Dolby TrueHD, DTS-HD Master Audio, Dolby Digital, and uncompressed LPCM.
- Ideal for connecting to soundbars, AV receivers, or stereo speakers.
