Electronic Crossovers
Electronic crossovers are designed to pass only
a certain range of frequencies through a circuit.
There are two types of eletronic crossovers: High-
Pass and Low-Pass.
A High-Pass crossover will allow only those
frequencies above (higher than) the crossover
point to pass through. This type of crossover is
used on tweeters to protect them from low and
midrange frequencies and on midrange drivers to
protect them from low frequencies.
A Low-Pass crossover will only allow those
frequencies below (lower than) the crossover
point to pass through. This type of crossover is
used on subwoofers to keep midrange and high
frequencies from being reproduced.
A combination of High- and Low-Pass crossovers
may be used to fliter both and low frequencies
passed to a device such as a midrange or
mid-bass driver. This is called a Band-Pass
crossover.
There are two important numbers to consider when
considering a crossover - the cutoff frequency - fc
and the crossover slope.
The crossover frequency determines the point at
which the filter will start to work. For example, a
High-Pass crossover set to 100Hz will attenuate
the frequencies below 100Hz and pass frequencies
above 100Hz.Crossover slope describes the
rate at which the crossover attenuates those
frequencies.
Speakers are designed to operate within a specific
range of frequencies. Sending frequencies to
a speaker that it was not designed to handle
reduces its performance and could result in
poor sound quality. For 2009, Clarion includes
electronic Low-Pass and High-Pass crossovers
on the CZ309, CZ509, FZ409, FZ709, CX609,
NX509, VX709, and VZ709 source units.
The electronic crossovers found in Clarion source
units not only affects the pre-amp outputs, but the
signal being sent to the internal amplifier as well.
This means you can use a high-power source
unit to run your speakers, while an amplifier and
subwoofer can handle low frequency output.
Clarion electronic crossovers are all adjustable for
frequency and are easy to implement.
The following chart outlines the crossover
functionality in each unit.
