Post subject:  REAL basics question from an non tecnical person...

OK, as most of you that have read my posts know, I am not very technically inclined. I don't know all the jargon either, but if explained in simple terms, I catch on quick.

Here's my question, on my Mackie DFX12 mixer, there is a 5 band graphic EQ. I am just not sure what each band does. The bands (from left to right) are 60Hz, 250Hz, 1KHz, 31.5kHz, 12khz. What type of sound does each of these represent?(ex: 1KHz controls the highs, while 250 controls the bass, etc.)

Right now I have them all zero'dout and hit the eq bypass button. I hate having features and not using them. If I know what they control, I can adjust semi- intelligently.

Thanks in advance.

Having them set at zero is in effect turning them to bypass but..... I keep mine set to zero, to start. when you are settin up, set the volume where you will probably be playing it. go to the middle of the room and listen. If you hear too many highs the back down the highs starting at 12 khz and work your way back. now this is for the overall out. you also can set your highs and lows separate for the line in, and each mic, so if you have mics that are too tinny.... the use the control for that mic channel and adjust the highs out of it there. remember the "eq" is for the main overall out to the amp. so it gets set after you have already set all the other channels to your liking. I used highs as an example the same would apply to lows etc. If you are using the reverb for the mics, make sure the efx 2 knob is turned counter clock on the "music in" channel, you dont want reverb etc in the music, only the vocals.

hope this helps

Gotcha Dr. D. I figured out the effects and the mix OK, but what I was looking for, was what each frequency represented. Kinda like on each channel there is the Hi/Low knob- I know what those mean.

So if 12khz is high, do they go down from there, or are rest highs, mids, or lows in order, or is there more to it??

12khz will probably be heard in like cymbals and very highs.
6khz will possibly be high horns and sax and such
1khz +or - is about the range of the human voice.
500 hz mids or low pitch vocals.
160 hz is lows & bass
80 on down is sub bass..
is this what you were looking for?

60 hz = low frequency (low bass)
250 hz = mid bass (can be a muddy frequency if overused)
1khz = midrange frequency (where most vocal frequencies reside)
3.5 khz = mid/high frequency (can brighten up a muddy mix)
12 khz = high frequency (crisp frequency)

Don't be afraid to play with your mixer. Read the manual & get to know it. Mackie is pretty good at explaining things in terms that anyone can understand.

Thank you both! That is what I was looking for!!!

And yes, the Mackie instructions are very helpful, but they didn't explain this particular thing.

Thanks again.

dbk,
If you get feedback, try cutting differant bands on your eq to remove it.
