Most PA boards should have a line-level out for each channel - this is
to feed outboard signal processing gear and is usually labeled "insert"
or some such.  It is in the format of a TRS ( Tip-Ring-Sleeve ) 1/4"
phone jack with the signal routed into and back from the processor
through the same jack.  You would still need another mixer to combine
each of the channels into your tape deck.
The other option is that most PA mixers will actually allow for several
different output mixes - you have outputs going to the house speakers
but you also have outputs going to the monitor system and to the effects
system and if there is a spare set of sends, these can be used for a
second mix.  You would have no control over this mix since it would be
done from the PA board entirely but if you can set it up beforehand, it
is a good option!
The thing to do is to contact the sound person first and see what kind
of board they plan to use and let them know what you want to do.
Usually they are more than willing to help.
