ART Pro Audio 311 - 2way Crossover w/ Subwoofer Out - Manual (Page 8)

OPERATION
The following guideline refers to a P.A. system, but the same basic
ideas apply to a home recording setup or a Hi-Fi system.
A stereo 2-way sound system is typically set up as follows: Separate
high frequency (horn or tweeter) and low frequency (bass) cabinets are
used for each side (left and right) of the sound system. The crossover
is used to split each side of the stereo signal into two frequency bands,
which will feed separate power amplifiers. This arrangement
accomplishes two things: it allows the proper frequencies to be routed
to the proper speaker cabinets and it allows the amplifier to produce
power more efficiently to the speakers it is driving.
It is very important that you use caution when selecting the
crossover points for any system. Refer to the documentation that
came with your speaker cabinets for information on their proper
frequency ranges. This is especially important for high frequency
horns; damage may occur from sending lower frequencies than
specified into the drivers!
Signal Flow
In most situations, the crossover is the last piece of equipment in the
signal chain before the power amplifiers. Signal flow is as follows:
From the output of the mixer to an equalizer (Sometimes, for system
protection, a limiter is placed between the mixer outputs and the
equalizer, or after the equalizer.) From the equalizer to the crossover.
From the crossover to the power amplifiers. From the power amplifiers
to the speaker cabinets.
Here are some tips to help you with your initial setup.
1. Set all level controls to their full counter-clockwise position (-30dB.)
2. Connect the outputs of your mixer (or equalizer) to the inputs of the
311
. If stereo, Channel One is Left.
