LOL! I meant the miggy audio is real hot as in LOUD at low volume.
Noted
I don't think it's loud at low volume however, it's a line level output of about 0.75V RMS, which is pretty standard. The software volume control works normally and gives expected levels out. I have an audio tone generator
here if you want to play around with it. Keys 1-9 set the audio output level. If low volumes are still too loud, then whatever you have receiving the audio is probably expecting a different range of audio.
Makes a guy wonder why C> didn't add a small circuit and input pins like that on the MB (they thought of everything else!).
Mainly due to the fact the A1200 was never intended to have an internal CDROM drive. Would have been cost related as well. By the time you put in all of these little extras "just in case" into the design, the final price ends up being higher. It's not just the cost of the components, but also it's another thing that needs to be tested during production.
I mean, did the A3K/A4K have a proper on moherboard preamp to mix CD audio with? If so, maybe an A3K/A4K schematic, or even a CD32 schematic, would provide proper circuit values.
The audio stage in the A4000 is quite different as it has a dual op-amp following essentially a copy of the A1200 audio stage. This was added as a summing amplifier to essentially do what I described in the first post. You can't really make your A1200 do this without modifying the hell out of it and having nasty add-on bits, which would be especially ugly. But the information I gave you is probably the easiest, tidiest solution. Don't get hung up on the resistor values, if my estimated value ends up with audio way too loud, just increase the resistor by a factor of two or four and keep going until you're happy. It's a summing amplifier, not rocket science. Or you could use 10k pots instead, but personally I wouldn't bother.
Ian's mixer will work, but from a quick glance at the design, it's intended to *replace* the Amiga audio output and probably be mounted in a desktop or tower case. What you want is to mix put audio from CDROM drive onto the A1200 standard RCA connectors, right? In this case, this isn't what you want.
