Televes 553702 T.0X TWIN QPSK/PAL Stereo CI Prof CAM

The 558701 TWIN QPSK-PAL CI modulation conveyor with PROF CAM allows the user to select two (2) TV / radio channels on one transponder (of the same band and polarity) and convert them to two (2) VHF / UHF PAL channels, with stereo configuration. The drive allows access to encrypted services through the use of CAM to decode them. It has two 3.5 mm for frequency input, IF loop-through for passing the signal to other modules and RF loop-through for output and mixing of other channels for further amplification.
