PRODUCT LABEL - In this label are wri en the most important data informa on about the passive loudspeaker, model, impedance, maximum
applicable con nuous power, serial number.
The NEOS218PX doesn’t contain a built-in crossover fi lter so the two loudspeaker are directly connected to the amplifi 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 c result.
