Commodore Amiga 1200 Internal Audio Paula CD mixer HI-FI
A very small circuit that allows a volume-perfect mix between CD audio and Paula.
A great trade-off between soundtracks and effects.
The potentiometer is not required.
Crystal clear stereo audio!
Order the PCB with a thickness of 0.8mm or 1.0mm, 1oz.
Tested on Amiga 1200 (PAL) M/B revisions 1D.1 and 2B with CD-ROM Toshiba Samsung TS-L462.
Use shielded cable for headphones/mic or speakers.
Make connections as much shorter as possible.
The following passives must be removed from the motherboard:
R327, R337
C324, C334
Wires should be connected to:
POWER SECTION
-AV to C304 negative
+AV to C303 positive
GND to C303 negative OR C304 positive
INPUT SECTION
LEFT AUDIO input to the pad 1-2 of U15
