T-0X - TWIN - Umsetzter QPSK in PAL mit CI

Ref. 5537

The TWIN QPSK-PAL CI allows the user to trasmodulate two channels (TV or radio) selected from those in two satellite transponders (same band and polarisation), into two VHF/UHF PAL channels, with the possibility of stereo modulation.

The unit allows access to scrambled services by using a conditional access module (CAM) that performs the service’s descrambling.
Two 3.5 mm jack connectors that make available in baseband the two audio & video channels of each module.
IF loop-through for the input connectors on the top of its front, in order to enable the passage of the input signal to other modules.
RF loop-through for the output connectors on the bottom of its front, in order to mix the channels for further amplifi cation.
