While designing the Pcd for my Sid-Synth, ArSid, I came to the next bump. And that is (as the title say) the next.
When studying the FpgaSid, I read about a Raw Audio signal, which is a thru-hole soldering island on the Fpga-Pcd.
In the image, in the upper-right corner, it is the gold-coloured circle, which I named "Audio 2 Raw".
But there is also an End-amp on the PCB. That End-amp is directly used in the replacements in all Cbm-computers.
1) How is the sound-quality of the audio from the Sid2 (so thru the End-Amp), compared to the Sid 1 (the Trans-Amp on the Computer-Pcb)?
2) The End-amp on the FpgaSid, is it the same as used in the schematics of the Cbm64?
Or is there a new amp designed?
3) The sound of this Audio 2 Raw, has it (about) the same specs as the Audio Out of the Sid 1 (which is on pin 27)?
