13515 SETUP TARGET CURVESThe SDP-75 implements Target Curves as a powerful tool for achieving the requiredfrequency response from your system. For every speaker in the room, a target curvecan be defined in terms of:Amplitude only / Amplitude and Phase / Amplitude and Group DelayOne or more channels can be linked in order to share the same target curve for several speakers.15.1 OVERVIEW OF THIS PROCEDUREIn the SDP-75, setting target curves is a very straightforward procedure:• Decide if you want to apply the same target curve to all the speakers (except subwoofers), or if you want toapply a different target curve depending on the type of speaker.• Link/unlink the speakers that will share the same target curve.• Setup the target curve for each group of speakers.• Press the Apply Change button.15.2 SETTING UP ONE OR MORE TARGET CURVESTo edit the target curve for one or more speakers, go to the Optimizer Settings/Target Curve page in the AdvancedSettings user interface:The most usual case is to link all the speakers except the subwoofer(s). Therefore, by default, the Link button is activatedfor all the speakers except for the subwoofer(s). If this is not the case, you can press the Link all but Sub button.Use the arrow keys of your keyboard or you mouse to edit the target curve:• The green dots correspond to the required values for each frequency,• The yellow line displays the expected result, taking into account the behavior of the filter.Press the Apply Changes button. This button becomes orange as soon as you change some setting that requires a newcomputation of the optimization filters.Save as a new preset. This will allow you to compare the sound with and without the target curve.
