12V Ext; the X1 can be remotely turned
on or off when it detects a DC control signal from
another component in your system. The exter-
nal trigger will accept 5 - 24 volt (DC) signals.

Master Gain (Front Panel)
The Master Gain control allows you to adjust the
volume of the subwoofer relative to the moni-
tors. Use the Master Gain judiciously. A prop-
erly calibrated subwoofer blends seamlessly
with the Monitors or satellites without calling
attention to itself. Here are some
general guidelines for setting the
Master Gain control:
Begin by playing some stereo
music you are familiar with. Set
your AV Receiver or Surround Processor vol-
ume to a comfortable listening level.
increase or decrease the Master Gain on the X1
crossover, listening for a natural frequency bal-
ance between the subwoofer (or tower bass
module) and the front left and right monitors.
When properly balanced, you will hear natural
bass extension, without being aware that it is
coming directly from the subwoofer.
Once the Master Gain is set, the volume control
on your AV Receiver or Surround Processor will
control the volume of your entire system, includ-
ing the subwoofer.
LFE Gain Control (Front Panel)
LFE is short for 'Low Frequency Effects'. Low
Frequency Effects originally were low frequency
sounds added to movie soundtracks in order to
increase their impact. For consumer electron-
ics, there is no standard con-
cerning what type of signal
might be present on the LFE
channel.
added an LFE input and gain
control to the X1 so that you can
integrate whatever is present on the LFE chan-
nel with the signal being reproduced by the rest
of the system.
After you have set the Master Gain level as
described above, play a multi-channel signal
through your system (as from a movie).
Sources with lots of bass output will be the most
useful. Adjust the LFE gain control until the
bass produced by the subwoofer reaches the
desired level. Most users initially set the level of
the LFE gain control at too high a level, so be
prepared to adjust the control over a long period
of time. You have reached an appropriate level
setting when movies soundtracks have impact
and music sources have punchy bass, but the
overall character of the bass produced by the
Slowly
subwoofer is not thick and ill defined.
The level of the signal on the LFE channel
varies considerably from source to source, so
you may need to use the LFE level trim featured
in most receivers and processors to adjust the
LFE level on a source-by-source basis.
There is an LFE "Thru" output on the back of the
X1. For more information concerning the use of
