Hi-Pass/Lo-Pass
The Dx46 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). Additionally the Trim pa-
rameter can be used.
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 Free 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. 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 at-
tenuates 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 X-Over Delay screen, press the X-Over button found on the output processing menu. Subsequent
button presses will toggle the display between OUT 1 to OUT 6. Use the Value Up and Down buttons to select the
X-Over Delay screen.
HINT: The X-Over Delay parameter is used for the alignment of transducers within cabinets. Opti-
mized delay values are included in Electro-Voice Speaker Settings and should not be edited.
Use the <SELECT> button to navigate between the X-Over Delay parameters. Adjust the values of each parameter
using the up/down VALUE arrows.

FIR FILTER
To access the FIR FILTER screen, press the X-Over button found on the output processing menu. Subsequent but-
ton presses will toggle the display between OUT 1 to OUT 6. Use the Value Up and Down buttons to select the FIR
FILTER screen. The FIR FILTER screen shows the Name of the currently used FIR filter.
Use the <SELECT> button to select the Active/Bypass parameter. Activate or Bypass the FIR filter using the up/
down VALUE arrows. Configuration of the FIR filter itself is only possible using the IRIS-Net software.

Description
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.
The user may select betwen time and distance display. Distances are automatically converted into delay times. This calulation also
includes the influence of the environmental temperature based on the Temperature parameter in the Setup Menu.
Setting this to Bypass disables the Crossover Delay.
