Model 1398B distributes HDMI audio and video signals from one source to eight HDMI displays. Use the unique CEC Auto-Reset feature if you want to be sure that all connected video displays remain on input 1. This feature is especially useful in the retail demo environment, where customers can change inputs or turn TVs off. The 1398B sends a CEC reset command every 10 minutes to keep all TVs showing the intended content. The 1398B passes 3D signals, and indicates 3D content by an LED on each 1398B. Bitstream audio is also supported - including LPCM 7.1 channel uncompressed audio, Dolby Digital TrueHD (7.1), and DTS HD: Master Audio (7.1). Legacy codecs such as Dolby Digital and DTS core are also supported.
