the setting of the
selected parameter.
Main Speaker Parameters
Type [Sealed or Reflex]
Sealed should be selected if the main speakers are a sealed
or “closed” design. Reflex should be selected if the main
speakers are a ported or passive radiator design.
Low Frequency Limit [in Hz, from 20 to 90]
This parameter should be set to the main speaker’s
“minus 3 dB” bass extension specification. This can usually
be obtained from the speaker’s owner information or from
the manufacturer.
Sensitivity [in dB from 83 to 95]
This parameter should be set to the main speaker’s
sensitivity (or “efficiency”) specification (output level in dB
with a 2.83 volt or 1 watt input and at a 1 meter distance).
This can usually be obtained from the speaker’s owner
information or from the manufacturer.
Damping [from .5 to .9]
This parameter should be set to the main speaker’s “Q”
specification. It is not a critical setting and excellent results
can be obtained by using a setting of .8 for sealed speakers
and .7 for reflex speakers.
To recall a previously stored set of
parameter settings first press this
button, select which preset using
the Increase and Decrease
buttons, and then press again. To store a set of parameter settings
first press this button, select which
number to use with the Increase and
Decrease buttons, and then press
this button again.

Performance Parameters
Low Frequency Extension [-3 dB frequency in Hz, 15 to
40]
In Augment mode only settings at least 5 less than the
Low Frequency Limit setting are available.
This setting determines how extended the left and right
channel bass reproduction will be. The lower the number the
more complete the reproduction will be. However, a very low
number will place somewhat more demand on the subwoofer.
The louder you play and the larger the room the harder it is
for the subwoofer. If the subwoofer cannot play loudly
enough you can either increase this number (to 30 or 35) or
add more subwoofer units to your system.
Low Frequency Level [boost or cut in dB, -6 to +6]
This setting controls how much extra left and right
channel bass will be produced by the main speaker/
subwoofer system. Normally it should be set to zero. It
provides increased or decreased bass energy, in the range
below 80 Hz when in crossover mode, and below the main
speaker’s low frequency limit when in augment mode.
Crossover Frequency [in Hz, 40 to 99]
This parameter is only available if Crossover Mode is
selected. Only settings above the Low Frequency Limit
setting by 10 to 30Hz, depending on speaker type and
damping, are available.
This setting determines the frequency below which
energy is directed away from the main speakers and to the
subwoofer. Unless the main speakers are very small, it is
usually preferable that this setting not be higher than 80.
Lower settings will usually provide better sonic results but
will also place more demands on the main speaker to
reproduce bass.
LFE Level [in dB, 0 to 10]
This setting determines the loudness level of the special
effects channel information. Zero is normal, higher numbers
increase the level.
