also be used to insure that low-frequency energy is not accidently routed to the mid-range or tweeter
drivers that may result in potential damage.
Available DSP 260 crossover parameters are Type and Frequency.
To access the Crossover 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 Low Pass/parameters. Adjust the values of each parameter using
the up/down VALUE arrows.
The DSP 260 Crossover offers a variety of HiPass and LoPass filters depending on the configuration
output selected along with a variety of selectable filters and frequency ranges that are adjustable using the
up/down VALUE arrows.
Type
Type offers list of selectable slopes/response Q’s
•Thru
•6dB
• 12dB/ 0.5Q - 2.0Q
• Bessel: 12 dB, 18 dB or 24 dB
• Butterworth: 12dB, 18dB or 24 dB
• Linkwitz-Riley: 12dB or 24 dB
Frequency
Frequency offers a selectable frequency range from 20.0 Hz to 20,000Hz.
Hi-Pass/Lo Pass
The DSP 260 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.

60.0Hz
