The M series EQ bundle includes the URS Motorcity 7 band Q, the impersonation of the passive 7 band EQ used by the Motown sound engineers at first in 1965. These were the first with proportional Q, small boost/cuts have very broad Q, big boost/cuts the opposite. The second EQ included is the Vintage Cinema Equalizer. This one impersonates the original 6 band passive EQ used in cinema in the 1930's, a seventh band has been added to the plug-in. Both EQs frequencies are overlapping nicely and can be used as a 14 band EQ.
