I have a number of records with that legend on the cover.  RIAA stands for
Recording Industry Association of America.  I found a basic article about
it at:

A friend used to own a Pope-Motorola system which had an RIAA setting on
one of the controls.  Using that setting made no apparent difference.
The original cover of Monteux's Berlioz Romeo and Juliet on Westminster
had a diagram showing the positions of the various sections of the
orchestra.  There may well have been others.
