High and Low Pass Filters: These 4 dif-
ferent filter types allow you to quickly
choose a design for your system,
either to set up protection from low
and high frequencies, set up a 2-way
crossover with a subwoofer and mids/
highs, or set up a bandpass filter. The
filters can also be chosen slowly, with
considerable forethought and care,
possibly while mulling things over in
your favorite comfy chair, with a cup
of tea and a plate of delicious buttered
crumpets. As each filter type is chosen,
the current high pass and low pass fre-
quencies are shown in the adjustable
boxes just below.
To prevent over-stress of speakers by
sending frequencies lower than they
are physically able to handle, use the
subsonic filter. For most inwall speak-
ers, we recommend a setting of 40 Hz
or higher. Contrary to popular thought,
higher often sounds better for this low
frequency filter. Similarly, to save the
tweeters, be conservative with the
setting of the tweeter protection filter.
It could save you a service call.
As there is a plethora of power
available (do not be fooled by The
Director’s lightweight appearance)
you can set up a 2-way crossover with
a subwoofer playing the lows, and a
pair of speakers paying the mids and
highs. Enable the Low Pass Mode filter
and bridge-mono the output from one
zone for your subwoofer. It will just
receive the low frequencies (in mono)
and receive the combined power
from both channels. Then use another
zone’s channel pair in stereo with
the High Pass mode selected for that
zone, to power the speakers playing
the mids and highs. Select the same
input channel for both zones. See the
system diagrams for a picture of this,
or see the video on our website of our
technical support engineers perform-
ing an interpretive dance.
Loudness: Select this for the zone for a
low frequency boost at lower listening
levels
Signal Sense: Select this, and the zone
will turn on automatically when it
senses a signal present at its selected
input.
Once you have the EQ settings just the
way you like them, you must save the
settings. Please see the details on the
next page.
