The NEOS215PX doesn’t contain a built-in crossover
fi
lter so the two loudspeaker are directly connected to the ampli
fi
er outputs. For this reason,
an external crossover is required in order to
fi
lter properly the sub-woofer and to combine it with top units.
The crossover can be either analog or digital, however we recommend the PROEL ASO25 as analog processor or the PROEL PC240/260 as digital
processor.
In the following table PROEL suggest the PROCESSOR parameters for PC240/260; these parameters could be used to set also other equipment
obtaining similar acous
