Hi-Pass/Lo-Pass
The DSP 600 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 parameter
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 link-
ing. The Type parameter defines the filter characteristics of the crossover Hi-Pass filter. Different slopes and filter re-
sponses (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 attenuates frequencies
below (the crossover point). On the contrary, a Low Pass filter passes frequencies below the crossover point and atten-
uates those above.
Crossover Alignment Delay
To access the Crossover Delay 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 X-Over
Delay screen.
HINT: The X-Over Delay parameter is used for the alignment of transducers within cabinets. Optimized delay val-
ues are included in DYNACORD 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.
Parameter Description
Use this parameter to compensate for physical offsets of the acoustic centers of transducers within a loudspeaker cabinet. For example, due to
Delay
cabinet construction, the acoustic center of a high frequency transducer may be mounted behind or in front of the acoustic center of the low fre-
quency transducer. The Delay parameter can align the audio signal between the multiple transducers within the loudspeaker.
Unit 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.
Active/Bypass Setting this to Bypass disables the Crossover Delay.
FIR FILTER
To access the FIR FILTER 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 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.
O DELAY
UTPUT
To access the Output Delay screen, press the SPEAKER Delay button. Subsequent button presses will toggle
the display between OUT 1 to OUT 6.
HINT: The DSP 600's output delays can be used to compensate for the positioning of cabinets or speaker arrays
relative to each other or the original sound source, for example aligning the PA to the stage or aligning the
full-range loudspeakers to the subwoofers. The Output Delay parameter determines the delay time of the
corresponding channel or the distance between different loudspeaker clusters.
