This is untrue.  Mac II's have TWO 44.1Khz output channels.  That is,
the built-in hardware can produce stereo, 8-bit, 44.1 K samples/sec.

When digitizing, the MacRecorder is limited to 22 K samples/sec.  A
Mac II (because of it's speed, probably) can simultaneously accept input
from two MacRecorders at 22 K, giving stereo, 8-bit, 22 K samples/sec.
