What makes the 1398B Unique?

  • When activated, CEC Auto-Reset triggers a command every 10 minutes via the CEC (Consumer Electronics Control) circuit. Use this feature to keep all displays in the distribution network showing content on HDMI input#1. This feature is very useful in retail environments or anywere the public has access to TV controls, turning them off or changing inputs.

  • EDID* SWITCH: In TV mode the 1398B reads the EDID on output 1 and records it, then allows the source to send matching HDMI signals to the other seven HDMI outputs (supports 3D). In STD mode the 1398B uses its built-in EDID, which is set at 1080p@60/12bits for video and LPCM 2Ch for audio (does not support 3D). Use this setting if there is a problem getting the source to send a signal to all of the connected displays.
