Graphic equalization is by individual zone and with both
channels within that zone paired by default. You can “unlock”
the zone/channel pair by clicking the “Unlock” checkbox
for each respective band. You also have the option of setting
the EQ curve globally for The Director by enabling the “All
Zones” checkbox.
Setting the EQ is done by dragging the EQ slider to the
desired position, by clicking where you want the position/
value to be or by clicking the +/- buttons. Please see a later
section for a discussion of the methods and benefits of equal

ization.
The two bands of parametric equalization are by zone
with both channels locked at all times. Parametric equaliza

tion can be very powerful however it takes some work to
adjust properly, can easily be done wrong, and is much easier
to use if you have some instrumentation/audio analysis gear.
See the later section for more discussion on EQ.
Saving EQ memories and Import/Export:
It is important to save your Signal Processing to a
memory. If you do not need to have multiple EQ memories
for recall, it is still necessary
for the Signal Processing to
be saved should the power go
out. When saving your Signal
Processing, the Save function
saves all 8 zones of Signal Pro

cessing. Once these are saved,
you can export these settings
from the configuration page
for back up purposes or for
making a template that can be
repeatedly used.
To prevent overstress of
speakers by sending frequen

cies lower than they are physi

cally able to handle, use the
subsonic filter. For most in-
wall speakers, we recommend
a setting of 40 Hz or higher.
Contrary to popular thought,
higher often sounds better for this low frequency filter. Simi

larly, to save the tweeters, be conservative with the setting of
the tweeter protection filter. It could save you a service call.
