EQ Settings on popular DJ mixers

Do popular DJ mixers publish the center bands and bandwidth/Q factor on their channel EQs, on a spec sheet or similar? I know the band gains are often listed right on the panel (and tend toward the -26/+6 or -infinity/+6 as standards), but I’d love to avoid having to get my hands on a mixer and testing it with a spectrum analyzer to know the EQ settings on that particular mixer.
