OPERATION NOTESOPERATION NOTES
Because of the Maag Audio EQ4’s unique design, phase
shift is very minimal. This helps the user maintain the
integrity of the original sound and enhance the “Airy”
frequencies, while tonally shaping the sound from the top
to the bottom. The lack of phase shift and the AIR BAND®
make theEQ4® great on anything that needs EQ shaping.
The EQ4’s band passes all interact with each other.
Increasing the AIR BAND® gain will also increase the overall
gain to a small extent. This is normal and is a necessary
by product of the design. This happens because of the
interaction (summing) of the AIR BAND® with all of the other
band passes. This interaction is a necessary part of the design
toensuretheintegrityofthesoundismaintained. Tocompen-
sate for the added overall gain, simply turn down each of
the 5 band pass knobs equal amounts. An example would
be two clicks down on all 5 knobs. The EQ will remain the same
shape, but the overall gain will be lowered. This compensates
for the extra gain added from the interaction of the boosted
band passes. This is the correct way to get the desired results
from the Maag Audio EQ4®. Here is another way to look at it:
If lifting a desired frequency, you may want to consider
bringing down the level of the other band passes above
and or below; always remembering the band passes inter-
act with each other. This is a dierent approach from other
typical equalizers.
OVERVIEW & OPERATION NOTES
