1.0 PREFACE
In most of the professional audio applications, multiple speakers
are employed for covering the whole audience area as well as
frequency band. When sound waves are generated with multiple
speakers, proper arrangement is a standard and recommended
practice by audio design engineers and installation technicians.
Phonic provides this active crossover as part of the speaker sys-
tem, which work together with speaker drivers, highs or lows, and
ampliers, big or small. This crossover will be successful if you
carefully design and align the whole speaker system according to
the following explanation and recommended practice.
1.1
MULTIPLE-WAY SPEAKER SYSTEMS
Full bandwidth covering 20Hz to 20KHz as human audible band,
no single speaker driver can cover this range with wave length
differ by 1000 times with good quality and sufcient sound pressure
level. To deal with this limit, audio engineers need to use multiple
speaker drivers for different frequency band, and we call these
designs as multiple-way system. Multiple-way means different
speakerscoveringdifferentfrequencyband,andmultiplespeakers
could be in the same band. For professional applications, 2-way
and 3-way designs are most popular conguration. To build a 2-way
or 3way speaker system, crossover network is needed to divide
the frequency band into high and low (or high, mid, low) section.
Crossover can be passive or active. Passive crossover can be
foundin smaller speakersystemthat isassembledwith inductors,
capacitors, and resistors. Amplier send in the signal to the passive
crossover network and then to the high and low frequency speak-
ersaccordingly.Activecrossoverdid thisdifferently, it ispositioned
before the power ampliers. Then, the power amplier send the
signaldirectlytothehighorlowfrequencyspeakersdirectlywithout
the passive crossover inserted. The benet are:
More solid bass for lower resistance between speaker and
amplier that maintain effective damping factor.
Lower inter-modulation distortion (IMD).
Save the insertion loss, normally in the range of 1 to 3 dB.
That means save the lost from 20% to 50%.
Increase power efciency for less composite signal that
will demand lower voltage swing of power ampliers, and
still provide the same sound pressure level.
Save the high frequency drivers from damage by large
low frequency signal clipping the power ampliers
which generate high level harmonic signal. This is the
phenomenon that underpower amplier will burn tweeter
when clipping.
Iftheuserdoesn’tfollowtheexactproceduretoset-upthespeaker
system with active crossover, the result is always very bad and
worst than passive crossover speakers. Because the passive
crossover was already properly adjusted by the designer and
maker.
OK, let’s see how we can get the best of the system performance
with Phonic PCR2213 Plus.
1.2 PCR2213 Plus THE ULTIMATE
CROSSOVER FOR ADVANCED
SPEAKER SYSTEM
The PCR2213 Plus is a very high quality active crossover. It is
designed with 2, 3 or more way speaker systems in
mindwith 1,2 ormore PCR2213Plus toachieve it.ThePCR2213
Plus may be used with large sound systems in
auditoriums,theaters,pubs,amusementparks,ortouringconcerts.
Also for high quality bi-amp stage monitors,
or adding a mono sub-woofer for studio monitors in a control
room.
The Phonic PCR2213 Plus is a high precision tool with a lot of
advanced features:
Stereo 2-way or mono 3-way operation.
Reasonable ways speaker system with multiple PCR2213
Plus.
Industrial standard state variable 24 dB/octave
Linkwitz-Riley lters with zero phase error at crossover
frequencies.
Perfect at summed amplitude response at all Crossover
frequencies.
Independent limiters on all outputs with pre-dened time
parameters.
Latching mute push buttons on all outputs. It is a vital
function during setting up and troubleshooting.
LED indication on all important switching functions for
easy status identication.
Crossover frequencies continuously variable from 80 -
8000 Hz
Time/phase alignment via polarity switches and 4 msec
time delay controls
Switchable horn EQ curve to compensate the HF roll-off.
RF and Subsonic input lters.
High precision components and potentiometers ensure
excellent quality and accuracy of settings

2.0 DESIGN YOUR SPEAKER SYSTEM WITH PCR2213 Plus
When designing the speaker system, rst determine the frequency bandwidth you want to cover and the maximum sound pressure level
you want to achieve. Select those components that meet your demand. Carefully note the frequency range each driver covered. Following
are some most popular conguration, PCR2213 Plus is not limited within the listed application. Multiple PCR2213 Plus can form even more
than10-wayspeakersystem, although it is not practical.The recommendedcrossoverpointsare listed foryour reference, your components
will fall in the recommended range mostly, but exception exists!
2.1 2-WAY SYSTEM (Ref:Figure 1)
PCR2213 Plus is capable of dual 2-way system in stereo mode. The crossover frequency can be anywhere between 80 to 8000Hz. Most
2-way system crossover between 500 to 5000Hz. Following are the table of popular 2-way conguration and recommended crossover
frequency:

2.2 3-WAY SYSTEM (Ref:Figure 2)
PCR2213 Plus is capable of single 3-way speaker system with one unit. The low/mid and mid/high crossover frequency can be set between
80 to 8000Hz. Most 3-way system have low/mid crossover point at 200~2000Hz, and mid/high at 800~8000Hz. Following are the table of
popular 3-way conguration and recommended crossover frequency:

2.3 PASSIVE FULL RANGE WITH ACTIVE-CROSSOVER SUB-WOOFER (Ref:Figure 3)
PCR 2213 is very suitable for sub-woofer application and is capable of this system with one unit. The crossover frequency is always low
at 80~200Hz. Following a table to list some popular conguration:
Figure 3:Typical Passive 2-way + Subwoofer
PCR 2213 has a sub-switch in the rear panel. This switch will sum the low frequency part of both channels and send it out from both low
outputs. When you are using this type of speaker system with one or more sub-woofer boxes, it is recommended to engage the switch and
put all the woofer boxes together in the center line between the stereo speakers.

2.4 STEREO ACTIVE 2-WAY WITH SUB-WOOFER (Ref:Figure 4)
Some people will regard this as 3-way, and it really is. There are 2 conguration you can achieve:(1)Treat it as 3-way and do it as the same
as 2.2. (2)Treat it as 2-way plus sub-woofer as the same as 2.1 + 2.3.
The later conguration benet the summed sub-woofer output from both channels, and thus better than pure 3 way conguration. No matter
which conguration, you need two PCR2213 Plus for this system.

2.5 STEREO ACTIVE 3-WAY WITH SUB-WOOFER
Some people will regard this as 4-way. But most 4-way system is actually 3-way plus sub-woofer. There are 2 conguration you can
achieve: (1)Treat it as 4-way and put two PCR 2213 in each channel, you will need four PCR 2213. (2)Treat it as 3-way plus sub-woofer
as the same as 2.2 + 2.3, and you are using three PCR 2213 for the whole system. The later conguration benet the summed sub-woofer
output with both channel, and saves you one PCR 2213. Although we appreciate if you would like to buy more unit, but technically we
don’t suggest this conguration.
2.6 4-WAY, 5-WAY ......
You can always achieve multiple ways system with multiple PCR2213 Plus, always send the next PCR2213 Plus with low frequency output
for easiest time alignment. Following the table for various ways conguration:
