X-Over Menu
The “Main Menu” contains controls that allow high-pass and low-pass filter
frequencies to be set and also permit different high pass filtering depending upon
the setting of the “Volume” control. This can compensate for systems that have an
uneven frequency boost applied to make them sound better at low volumes which
does not scale appropriately with increased volume.
•
Enabling the “Volume-based High Pass Filter” enables or disables this feature.
The main high pass and low pass filters on the right half of this screen are still
active unless set to “Off”.
•
The “Volume” control is a duplicate of that found in the “Main” menu placed here
for convenience. Monitor protection limiter activity (described earlier) will be
displayed in this control.
•
Two sets of “@ Volume” and “High pass filter” controls are provided to
customize the threshold and shape of the volume-based high pass filter.
•
The volume-based high pass filter sliders set the lowest frequencies permitted to
pass through the Monitor Output once the thresholds set in the “@ Volume”
sliders are crossed. If the “@ Volume” slider is set to “0”, that volume-based high
pass filter will be active at all volume levels. The default and lowest value (unless
disabled) is 15 Hz.
•
The two sets of volume-based high pass filter controls interact. If, for example,
the first “High pass filter” control is set to 135Hz with the associated “@ Volume”
control set to -35dB and the “Volume” is control set at 0.0dB, the filter will be set
at 15 Hz, which is the default frequency of the 2
nd
volume-based high pass filter
control.
•
As the “Volume” level is decreased you will see the high pass filter frequency
begin to rise. By the time it gets to -35dB – the threshold set by the first “@
Volume” - it will high pass at 135Hz, the frequency set in the first volume-based
high pass filter control.
•
In addition to the volume-based high pass filters, there are also fixed frequency
high and low pass filters for both left and right channels. These can be linked in
the “Channel Coupling” menu described below.
