HDE 8C QAM IP DIN – Overview
The Blonder Tongue HDE-8C-QAM DIN encoder digitizes and MPEG-2 encodes each input into a high-definition stream. The eight (8) program streams are multiplexed and then modulated onto four adjacent QAM channels in the 54-1002 MHz range (CATV 2-158). The HDE-8C-QAM/IP DIN (OPT 2) encoder includes an IP output to provide 8xSPTS. The unit ships with a supply of eight (8) H258C DIN Cables to for eight (8) H25 receiver connections. The H258C DIN to RCA Cable can be ordered separately for Non-H25 receiver sources.
