RF signal amplitude
This signal is measured at F851 just at the input of the
Furore. When no disc is in the player, we measured 54 mV.
Then a disc is inserted and played, at this moment the RF
signal increases. We measured 1.05 V amplitude and the
level of this input should be between 0.2V and 1.5 V. Then
we can play normally a SACD disc.
DSD outputs
With the diagnostic software, we can partially test the
DSD_PCM bus toward the DAC board. When you play a pink
noise, digital bit stream is coming out of the Furore and is fed
to the DAC board.
