The cassette converts 12 stereo audio channels from two COFDM and QAM
modulated transponders and the ASI input signal into 12 FM modulated stereo
output channels.
The RDS station code is automatically taken from the station name of the trans-
ponder or can be entered manually.
Via input A and a corresponding CA module scrambled channels can be de-
scrambled.
