Opps, they were for phase recersal switch on C11 and 22, the C24 used
them for headphone output with loading resistors, should have pulled
schematic first before answering.

The McIntosh C11 and C22 preamps have a single speaker connection on the
back. One from the amp's output & one to a single speaker. No impedence
is given and there is only 1 in and 1 out. What is this for and what
does the preamp do with the signal?


Those connections are for the phase reversal switch. One is from the amp and
the other connection is to one speaker. The slide switch reverses the
phase/polarity of the speaker.
