4.8.- PEQS - Output Parametric Equalization.
After the Crossover section we find the PEQS (Parametric Equalizer) for outputs..
By pressing either of these icons the Equalizer window will appear from where you can adjust these

4 - EDITING WITH DSX
The ideal total electricity response will be in case of 4th+4th LinkWitz-Riley or 2nd+2nd with phase
inverted on one of the channels. In other cases, you will be creating an enhancement of about 3dB for Butterworth
and a ripple of approximately ± 2dB on Bessel . However, you get a better response in the crossing area of both
ways, and that is because you solved phase problems, typical in these cases. Even so, we must never forget
the final response of the transducer itself connected to this configuration, because it will influence the final
phase response.
It is posible to obtain almost a flat response on the crossover area with a little ripple using the same type
of filter and order but by changing the frequency cuts, going down on Low pass, and up in High pass.
Linking channels
When you can adjust both independently, upper and lower crossover
filters, you will have the freedom to create asymmetrical crossovers with
different frequencies, slopes and types of filters. Necessary in many real
cases, where the use of these asymmetric crossovers, electrically speaking,
provides electroacoustic perfect crossover area.
