Here are the settings I current use for the 3000s Main EQ that are stored under USER1:

EQ1=4
EQ2=3
EQ3=4
EQ4=8
EQ5=10

For the vocal settings I prefer using High Male Qua for harmonies with the following settings:

LOW EQ=80 +2, MID EQ=2.0, 0.0, HIGH EQ=10, +9
NOISE GATE= OFF, -60, COMPRESSOR= ON, -20, 5.0, 110

VOCODER HARMONY CONROL= PLAY, OFF, LOWER, 35, AUTO, XF, OFF, 85

SET TRIM POT FOR MIC AT APPROXIMAELY 10:00 O'Clock position. (much of this will depend on the type and quality of the mic you are using)

NOTE: The vocal settins seem to work particularly well using the Crown CM-311-A headset mic, Sennheiser E-855 and Samson Q7. I have not used the Shure SM57A so I cannot comment on its performance with the above settings, but it should be good to excellent.

Hope this is of some help,

Gary
