- This is a simple two chip Audio Digitizer for the Amiga (specifically the
- 500, but the DB25 pinouts can be changed for the other models). The parts
- list is:
-
- Qty Item/Desc Value
- 1 Resistor 1k
- 1 Pot 100k
- 3 Caps .1uF,47pF,10uF
- 1 Mini Plug or RCA plug
- 1 Connector DB25
- 1 A/D converter ADC0804 (Heathkit usually has these)
- 1 Audio Amp LM386N (Radio Shack)
-
- This circuit will work with the program from the Perfect Sound digitizer
- with one small exception--it won't digitize in stereo.
-
- All the Vcc's (Pin 20 on the ADC0804 and Pin 6 on the LM386N) can be
- powered from the printer port (at least it is working for mine with no
- power supply problems!).
-
- Use the monitor signal level option in the Perfect Sound program to adjust
- the pot to the correct level (NOTE: If the circuit is hooked to a line
- level--e.g. to the Audio Out of a VCR or stereo--the pot should be turned
- WAY down, just listen to the "monitor" and you'll see what I mean).
-
- I do have this circuit built and running on my Amiga so I know it works.
- (I just hope you can read the diagram!)
