SYSTEM LAYOUT
The primary function of the crossover is to filter the audio signal. Basically, the
PLXR3B
divides the audio signal into three separate pars..... Subwoofer, Mid and
High. (See Figure #1).
Although the
PLXR3B
has rather simple connections, it is important for you to
have a general understanding of the operating range of your system to properly
setup the system as well as to make the final adjustments.

FULL RANGE VS. THREE-WAY OUTPUT
In order to reproduce the music in which it was recorded, your audio system
should have the ability to recreate all audio information from 20Hz up to 20KHz
(This is known as human audible range). One of the most important factors in
sound quality is the overall balance of the frequency response, better known as
the linearity of the sound. In a perfectly balance system, the low to high frequen-
cies are reproduced without missing information. Unfortunately there are many
factors that can cause loss of frequencies in your system. Some loss may be
caused due your speaker's frequency response, crossover points, and level
adjustment.
Before you set up the system it is best to first layout your system maintaining the
speakers operating range. The following graph will give a general idea of the
Subwoofer, Midrange and High operating range for the PLXR3B crossovers.
