Vision COFDM Modulator 2-programme

The V40-2000 COFDM takes 2 A/V signal sources and modulates them into a single UHF DVB-T channel in standard definition compatible with Freeview set-top boxes and IDTV’s.

The modulator has been designed to be simple to set up by the front panel removing the need to use a computer or handset. A single DTT channel can be created in the VHF or UHF bands for use with larger, more complex commercial SMATV systems. Compatible with the format of the V90-440 Quad single channel filter amplifier.
