5.5.9 Nucleus 908: System Audio Loop Scart (Europe)
Nucleus for testing the components on the audio signal path:
• The hostdecoder
• The analogue board
• The audio encoder
• The VSM
On the analogue board, audio is passed to the SCART
connector, where a SCART cable needs to be used to loop
back the audio signal to the digital board
