of Astra and other satellite signals.
Table 3 FM satellite sound
Notes
1. For other satellite systems, frequencies of, for example, 5.80, 6.60 or 6.65 MHz can also be received.
2. A de-emphasis of 60 s, or in accordance with J17, is available.
3. m/st/d = mono, stereo or dual language sound.
4. Adaptive de-emphasis is compatible to transmitter specification.
