Frequency
Frequency offers a selectable frequency range from 20.0 Hz to 20,000Hz.
Hi-Pass/Lo Pass
The DC-One Hi-Pass and Lo-Pass filters are determined by selecting the
Type
from the list of parameters,
(see list above) and by choosing a frequency range between 20.0 Hz to 20,000Hz. (See above)
The crossover filter generally consists of a low pass filter in one channel and a high pass filter in the
adjacent channel. This is where the frequency x-over filter’s Hi-Pass parameters are set. The Hi-Pass
frequency parameters are linked to the corresponding Lo-Pass frequency parameter unless in Full Edit
Mode or using the Configuration option. Please refer to the Configuration section of this manual for details
on the effect different Configurations have on channel linking.
The Type parameter defines the filter characteristics of the crossover Hi-Pass filter. Different slopes and filter
responses (6dB, 12dB with different
Q
values, Bessel, Butterworth, Linkwitz-Riley) are available and the filter
can be bypassed. Again, the Hi-Pass frequency parameters are linked to the corresponding Lo-Pass
frequency parameter depending on the Configuration that is currently being used. High pass frequencies are
set with a pre-determined frequency that attenuates frequencies below (the crossover point). On the contrary,
a Low Pass filter passes frequencies below the crossover point and attenuates those above.
Crossover Alignment Delay
To access the Crossover Delay screen, press the
X-Over
button
found on the output processing menu. Subsequent button presses
will toggle the display between OUT1 to OUT6. Use the <SELECT>
button to navigate between the Crossover parameters
.
Adjust the
values of each parameter using the up/down VALUE arrows.
•
Delay
- Use this parameter to compensate for physical offsets of the acoustic centers of transducers
within a loudspeaker cabinet. For example, due to cabinet construction, the acoustic center of a high
frequency transducer may be mounted behind or in front of the acoustic center of the low frequency
transducer. The Delay parameter can align the audio signal between the multiple transducers within
the loudspeaker.
•
Polarity
- The polarity of the audio signal can be inverted using this control.

60.0Hz
