Basic Installation
Factory default settings allow HDb2380 modulators to broadcast 8 SD sources with composite video and analog audio on 2 RF
channels over coax cabling, for reception at connected HDTVs. HDb2380 supports DVB-C cable format only.
1. Apply power.
2. Connect a Composite Video source to any Composite Video Input of the HDb2380.

directly connected. We recommend you keep the power at each HDTV below +20dBmV.
5. Set the TVs to Cable (not Air or Antenna) and DVB-C, inputs.
Specify Symbol Rate 6750 KS/sec.

to find the channels.
