LF Cutoff Switch
10
This control allows you to engage a high-pass filter that removes low-frequency
sounds from the monitors. This switch can be set in the following ways:
Flat This default setting allows your
monitors to play their entire
frequency spectrum with no low-
frequency filtering.
60Hz This setting engages a second-
order (12dB/octave) filter that rolls
off frequencies below 60Hz.
80Hz This setting engages a second-
order (12dB/octave) filter that rolls
off frequencies below 80Hz.
If you are using your CX monitors with a
subwoofer that does not have a built-in
crossover, set this switch as close as
possible to the low-pass cutoff frequency of
your subwoofer. The low-pass cutoff of the
subwoofer should be listed in the “technical
specifications” section of the subwoofer’s
User Guide.
If your subwoofer has an internal crossover that sends high-frequency signals out
to your main monitors through a pair of outputs, leave the LF Cutoff Switch on
your CX monitors set to “Flat.”
TIP: Many subwoofers feature
a low-pass cutoff frequency of
80Hz. If you are not sure about
your subwoofer, use this setting
as a starting point.
TIP: This switch can also be
engaged if you wish to hear what
your mixes would sound like on
speakers with smaller woofers
(such as those found in most
televisions).
