- The audio chip in your 64/128 generates an audio output; this can be separated
- form the video signal using the right cable. This audio output can be plugged
- into anything that'll accept it; you can plug it into the audio jack of an
- appropriate monitor, or into a channel of a stereo system. The second SID
- chip would generate another audio output, and you would have to find another
- channel to play it. If you have a 1084S monitor, your 64/128 as it is only
- uses one audio channel, so you can use the other channel for the SID from the
- setereo cartraidge (and thus you really do have stereo). If your built-in
- SID's audio output goes to one channel of a stereo, you can put the second
- SID's audio output to the other. A number of other combinations are possible.
- Whether or not you get true stereo will depend on how you hook it up; if you
- have a mono audio system that will accept two input channels then, no, you
- won't have stereo output, just 6 voices.
-
- Question: does anybody know how well in tune the SID chips in the stereo
- cartraidges tend to be with the SID's inside 64's, 128's, and 128D's?
