Well if you look at the block diagram of the DJM850 file (which applies to the DJM900 & 850 btw) the limiter is only on the master output after the attenuation select. http://www.pioneer.eu/files/support/DJ/DJM-850/PEAK_LIMITER_E.pdf so yeah only the RCA & XLR outputs have the limiter chained through- attached a screenshot for ya.
