McIntosh C22 User Manual

the other the only control that is effective is
the TAPE JACK switch. (Note: Some portable
tape machines will drive the C22 even though
the TAPE JACK switch is in the RECORD
position.) This is not a normal circuit use and
a distorted signal usually results. For low-
distortion operation follow the recommended
procedure.
USING THE C22 WITH MICROPHONES FOR STEREO
Microphones in stereo may be used with
the C22. The two MIC channels amplify
microphone signals. They have a sensitivity
of 2 millivolts and an input impedance of 1
megohm. For lower output microphones in-
put transformers should be used to raise the
voltage output to the 2 millivolt range.
When the INPUT SELECTOR is turned to
the MIC position, the COMP control does not
operate. All the other controls operate and
may be used the same as for any other
program source.
