SACD Processor/Furore
With the following commands, the access of the Furore and
its SDRAM is checked.
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.
