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
ampliers, 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 sufcient 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 conguration. 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. Amplier 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 ampliers. Then, the power amplier send the
signaldirectlytothehighorlowfrequencyspeakersdirectlywithout
the passive crossover inserted. The benet are:
 More solid bass for lower resistance between speaker and
amplier 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 efciency for less composite signal that
will demand lower voltage swing of power ampliers, and
still provide the same sound pressure level.
 Save the high frequency drivers from damage by large
low frequency signal clipping the power ampliers
which generate high level harmonic signal. This is the
phenomenon that underpower amplier 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.

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 conguration, 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 conguration and recommended crossover
frequency:
Figure 1: Typical Active 2-way System

PCR2213 3
English
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 conguration and recommended crossover frequency:
Figure 2:Typical Active 3-way System

PCR22134
English
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 conguration:
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.

English
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 conguration 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 conguration benet the summed sub-woofer output from both channels, and thus better than pure 3 way conguration. No matter
which conguration, you need two PCR2213 Plus for this system.
Figure 4:Typical Active 2-way + Subwoofer

PCR22136
English
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 conguration 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 conguration benet 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 conguration.
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 conguration:

3.0 INSTALLATION
3.1 RACK MOUNTING
The Phonic PCR2213 Plus ts into standard rack, and takes one
unitheightofspace(1 3/4”).Additional4”depthfor the connectors
onthebackpanelisneeded.Besurethatthereisenoughairspace
around the unit for cooling and please do not place the PCR2213
Plus in contact to or directly on top of high temperature devices
such as power ampliers etc. to avoid overheating.
3.2 CONNECTORS
ThePCR2213Plushasto be connectedwithXLRplugs.Although
theinputsandoutputsarefullybalanced,theactiveservocircuitry
can be wired with unbalanced sources and loads as well.
3.2.1 Impedance
Both of the inputs impedance are 20k Ohms and can be driven by
most sources. If a device’s output requires a match load of 600
Ohms(mostlyfromoutputtransformers),600Ohmsresistorshould
be tied across pin 2 and 3 on the input connectors. As standard,
the outputs of the PCR2213 Plus are electronically balanced and
have an output impedance lower than 100 Ohms. When driving
transformer coupled loads, it may be necessary to create a 600-
Ohm source impedance. For this purpose, install two 247 Ohms
resistors in series with pin 2 and 3.
3.2.2 Unbalanced/Balanced Connection
Mostofthemistakesinaudioinstallationsareincorrectanddefec-
tive audio connections. In order to perfectly complete your instal-
lation, please pay special attention to the following section unless
you are already familiar with balanced/unbalanced operation.
What is an unbalanced system?
You can nd this system in most of home audio-video system. It
got one conductor to carry the signal, and the other conductor for
ground. Normally for lower level signal, the signal conductor is
shielded by the ground conductor.
What is a balanced system?
Balanced system transmits the signal via 2 conductors plus one
ground shielding conductor. The 2 signal conductors carry the
same signal but out of phase. For the balanced input stage, the
amplier will boost the difference of the 2 signal conductors and
remove the identical part (known as common mode signal.) of the
2 signal conductors. Because of the real signal is carried by the
2 conductors out of phase, so it is perfectly carry to the input. At
thesame time,the interference occursduring transmissionwill be
identicalpart(commonmode),because the signalconductorsare
run together, there is no chance they can be different, and all the
interference will be removed by the balanced input amplier.
The difference in between 2 operations:
Because the common mode interference immunity of balanced
system, and at the same time, the ground conductor doesn’t
need to carry any electrical current so that it means the ground
of the 2 connected units has identical ground level which is vital
to interference free system.
Let’slookback to unbalancedsystem, the signal electrical current
is from signal conductor to ground conductor, and that means the
groundlevelof2connectedunits are not identical.Thismeansthe
system is much more easier to be interfered with noise.
Running long cables is easy for balanced system but difcult for
unbalanced system, and lower noise is always characterized in
balanced system.
Because balanced system needs 2 conductors for signal and
1 conductor for ground, minimum 3 conductors are needed for
wiring balanced system. So dedicated system separates ground
and shield as 2 conductors.
Please read following section for proper wiring balanced and
unbalanced system:
3.2.3 The Correct Wiring for Balanced Operation
Always connect the main power with 3-prong plug. Make sure the
powersystemgroundisproperlydone.Don’tusegroundinsulator
plugadapterwithoutproperlyconnectthe groundindividually.This
is vital to a successful audio system connection. Always connect
the ground pin (PIN 1 in XLR) to the source unit, and disconnect
thispinatthe destinationunit.Thisconnectiontopologyis toavoid
grounding loop created by both connection of signal and power
ground. To utilize only the power ground, is because it always
has lower resistance and better distribution than signal ground. If
there is hum, a very possible cause is bad grounding connection
in the system. In case you can not nd the cause, try to connect
the ground pin of the input connectors. If the hum is reduced or
eliminated, check your power grounding system. Special atten-
tion while distant equipment racks, and/or large quantity of power
ampliers are used. Check the power ground between the racks
and power distribution strips with your electricity engineer. Do
make sure there is one and only one proper ground point in the
audio system (or connected video system.)
3.2.4 Unbalanced Operation

outputs which also function unbalanced inputs and outputs. The
cross-feedbackcircuitryrecognizestheconnectionof unbalanced
loads and compensates 6 dB level difference when one of the
signal is shorted to the ground.For connecting with unbalanced
source to the input of PCR2213 Plus, connect PIN 2 of XLR con-
nector to the source signal and the PIN 1 and 3 of XLR connector
ofPCR2213Plus to thesourceground. For connectedwithunbal-
ancedloadtoPCR2213Plus,thereare2possiblewiringmethods:

PIN 1 of XLR connector to the load ground. (2): Connect PIN 2 of
XLR connector to the load input, and connect PIN 1 and 3 of XLR
connector to the load ground.
3.2.5 Balanced Operation
The electrically balanced connections have the benet of Common
Mode Rejection which eliminates externally induced interference,
such as mains hum etc. Balancing is especially useful when long
cablerunsareusedbetweenpiecesof equipment.Forconnecting
with balanced source to the input of PCR 2213, connect PIN 2 of

3.3 MAINS CONNECTION
The mains connection of the PCR2213 Plus is made by using a
standard IEC receptacle and an universal mains cable. It meets
all the requirements of the international safety certication.
Makesureallthe units in thesoundsystemareproperlygrounded
with good connection. For your own safety, do not to remove the
ground connection within the units or at the supply, or fail to make
this connection at all.
The audio ground of the PCR2213 Plus is capacitor de-coupled
and isolate it from the power ground. Do not attempt to solve
ground loop problem by disconnecting the power ground.
3.3.1 Safety Fuse Replacement
Asafety fuse protects the unit from serious malfunction. The fuse
will blows in case of power problem or loading short circuits.After
removing. the cause, and the identical specication fuse blows
right after a new one replaced, there must be something wrong in
the unit. NEVER use fuses higher or lower ratings fuses or other
metal material. This can cause re and electric shocks and will
threaten your life and the lives of others.

5.0 HOW TO SET UP A MULTI-WAY
SPEAKER SYSTEM
5.1 EQUIPMENT AND INSTRUMENTS
Properly prepare all necessary equipment and instruments be-
fore hand will help you uently do the job, here are the list we
suggested:
5.1.1 Measurement Microphone (Cali-
brated and matched with RTA or ETF/
TEF)
Alignment should be carried out with a good quality microphone,
with a at response at least from 50 Hz to about 16 kHz. Placed no
less than 1 m (prefer at listening position, multiple measurements
required for larger venue) in front of the speaker system being
set-up, and at a vertical position between the drivers covering
the two or more bands of the system. Only one speaker system
at one time, never turn on multiple speaker system at the same
time, you will never properly tune the system!
5.1.2 Real Time Analyzer (RTA), Energy-
Time-Frequency (ETF or TEF), FFT, or
MLSSA including a Sound Pressure
Level Meter
RTAisa populardevicethatshowsthefrequencyresponsedirectly
on the display. ETF or TEF, FFT, even MLSSA instruments don’
show the frequency response directly, but after the instrument
taking enough samples and nished the calculation.
Precision measurement cannot be done by ordinary RTA, but it
is a handy tool to do some quick job and in near eld measure-
ment. For more precision alignment, ETF/TEF or MLSSA is
recommended.
Please refer to the user guides of the instrument you are using
for proper measurements.
5.1.3 Function Generator with frequency display
This is a sine and square wave generator capable of variable
frequency in the range of audio band. You need to have the
frequency digital display or you need a external counter for the
frequency reading purpose. This unit is needed to send out the
precision frequency signal to the system.
5.1.4 AC voltmeter
A good AC voltmeter (2 channel preferred) that reads in dB as
well as volts is recommended for measuring the input and output
level of each band.
5.1.5 Your familiar CDs
PreparesomeofyourmostfamiliarmusicCDscoveringlowtohigh
frequency. Vocalsingingandspeakingshallbe alwaysincludedas
thisismostsensibleto humanears.Experienceduserputtogether
frequent test reference sound tracks and standard signal such as
pink/white noise into one CD or DAT for convenient trial listening.
The instrument assist alignment will mean nothing without good
listening experience. If you found problem while listening, don’t
try to adjust the system without instrument. In stead, you shall
make use of the instrument to nd out the problem, there must
be something missing!
5.2 2-WAY SYSTEM LEVEL SETTING
Properly setting level guarantee best performing system. Please
follow the recommended procedure for best speaker system.
1. All system power off.
2. Connect the pink noise generator (on RTA or CD), the signal
sourcerequiredbythetestinstrumentandvariablefrequency
signal generator onto the main mixer.
3. Connect the measurement microphone to the instrument.
4. Make sure all the signal wiring is done properly setting on
PCR2213 Plus is done correctly.
5. Graphic equalizer at at setting (or bypass).
6. Compressor/limiter at bypass setting.
7. All level control on power ampliers at minimum.
8. Un-mute all output of PCR2213 Plus.
9. Turn on the system except power ampliers.
10. ConnectACvoltmeteratthelowoutputofthePCR2213Plus
under test.
11. Make sure all mute switches and phase invert switches are
not pressed. The limiter is off, subsonic lter is off and the
horn EQ is not engaged.
12. Set the crossover point [8] as design, send in the sine wave
from function generator at half of the crossover frequency.
Adjust the channel fader and master fader to 0VU on the
mixer.
13. Read theAC volt meter,itshould be around 0dBu depending
on the 0VU reference point of the mixer and the crossover
point.
14. Change the frequency of the function generator to the cross-
over point.
15. Adjust the crossover frequency knob [8] slowly around the
crossover frequency. Read the AC volt meter until it is 3dB
lower than previous step. This is the exact position of the
crossover point. Mark the position with a pencil.
16. Repeat the same procedure from step 10 to 14 with another
channel crossover point.
17. Measure the axis distance between the bass speaker and
high frequency driver (speaker), and calculate the approxi-
mate delay time to compensate the difference. Ref to 5.3 for
detail.
18. Now,shutdownallsignalsource.Makesurethereisnooutput
from the mixer by reading the level meter on the mixer.

11. Make sure all mute switches and phase invert switches are
not pressed. The limiter is off, subsonic lter is off and the
horn EQ is not engaged.
12. Set the LF/MF crossover point [8] as design, send in the
sine wave from function generator at half of the crossover
frequency.Adjust the channel fader and master fader to 0VU
on the mixer.
13. Read the AC voltmeter, it should be around 0dBu depending
on the 0VU reference point of the mixer and the crossover
point.
14. Change the frequency of the function generator to the cross-
over point.
15. AdjusttheLF/MFcrossoverfrequencyknob[8]slowlyaround

32. Un-mute the HF and MF, and turn up the level until the LF,
MF and HF are about balanced.
33. Turn up HF, MF and LF levels until the sound pressure level
reached 10dB below designed operating level. (If you set
the operating at 90dB, you shall reach 80dB. If you set the
operating at 100dB, you shall reach 90dB, so on and so
forth... Our recommendation is 0VU at 90dB SPL for most of
the application.)
34. Press down the low cut if you’re using vented LF speaker
which doesn’t extend to 30Hz or lower.
35. Press down the Horn EQ if you’re using HF horn which is
constant directivity design.

5.4 DELAY TIME
The speed of sound is affected by air temperature. You can cal-
culate the sound speed as following:
C = 49 * (459.4 + °F)1/2 in feet per second.
C = 20.6 * (273 + °C)1/2 in meter per second.
Where C is the speed of sound.
To compensate the offset between the speakers, the time will
equal to the distance divided by speed.
T = D/C
Where T is the delay time in second, and D as distance in meter
or feet between the speakers.
The maximum delay time is 4 msec, which equal to 1.42 meters
at 25°C or 4.52 feet at 72°F. This distance is sufcient for most
speaker installation except those separating the speaker cabinet
far apart. The very large long throw horns usually measure at 1.2
meters.If you have any huge horn to work with direct radiate bass
unit, it is a good idea to move the bass a little back than the horn
mouth. Keep the speaker driver distance within 1.4 meter will be
ne for PCR2213 Plus.
If you want to make a precise delay time adjustment, connect
the PCR2213 Plus with dual channel oscilloscope with PCR2213
Plus input signal measured by one oscilloscope channel and LF
output to the other channel. Send the sine wave into PCR2213
Plusandadjustthedelaytimeuntilthe horizontaltimeoffsetequal
to your design.
5.5 LIMITER SETTING
1. To properly set the limiter threshold. You need to nd out the
capacity of the speaker and associated amplier. Because
the threshold is global setting, we shall make use of the level
control on the PCR2213 Plus as well as those on the power
ampliers, so that it works with all bands.
2. Disconnectonesetofthespeakersandhookupdummyloads
(same value as the speaker loading) to the ampliers (You can
connect only one output of the amplier if you have multiple
for the same band, and turn them off without removing the
speaker connection.
3. Turn the threshold all the way up, and switch on limiters.
4. Let’s start from the HF output.
5. Turn up the mixer master level until the HF power channel
reached the threshold power you want to limit.
6. Turn down the threshold until the HF limiter indicator lighted.
Now you have done the rst limiter point. There are 3 more
(or 2 more ) to go.
7. If you keep all the output levels on PCR2213 Plus at 0 (12
o’clock),theLFoutputofthesamechannelprobablyreached
limitng at the same time. But the power amplier level maybe
higher or lower than the power you wish to limit. If the limiting
point is not yet reached, increase the mixer output level until
the limiter indicator is lighted. If it was too high already, bring
downthe mixer outputlevel until the limiter indicatorjuststart
to light.
8. Mark the output level at this point by measuring with AC
voltmeter.
9. Turn up the level control of the power amplier channel until
it reached the level you wish to limit.
10. Turn down the output level of PCR2213 Plus until the power
amplier output level reduced back to the level marked in
step 8. Now, this output limiter is done.
11. Repeat the same procedure for other output limiter.
12. After all limiter points are set, connect all the speaker loads
back and send in the pink noise via the mixer again at -20dB
(or -30dB) refer to previous level.
13. Measure the HF amplier channel used for previous setup
and write down the value.
14. Measure the other HF amplier channels and adjust them as
the same as the write down value.
15. Measure the LF amplier channel used for previous setup
and write down the value.
16. Measure the other LF amplier channels and adjust them as
the same as the write down value.
5.6 SUB Σ
In case the PCR2213 Plus Plus is used to work with sub-woofer
system, no matter mono or stereo, it is good idea to drive all the
sub-woofer boxes in the same phase with identical signal. Keep
those sub-woofers the identical design with identical boxes and
drivers at all possible. This practice is true regardless of whether
it is a big stage installation or small in studio monitoring.
5.7 HORN EQ
30yearsago,thehorndesignscouldnotreachconstantdispersion
over the frequency range it covers. The higher the frequency, the
narrower the covering area. 20 years ago, the design of constant
directivity can be realized, so that the energy can be distributed
wider area especially in higher frequency. This expose a problem
not noticeable in the past, because the high frequency energy
output from the driver will drop gradually as the frequency goes
higher. It was not a problem on axis before these constant direc-
tivity horns invented, and compensated with the beaming char-
acteristic of older horn. But to take good care of the audience in
various venues, constant directivity design provides much better
performance between on axis versus off axis. To compensate
this roll-off tendency, PCR2213 Plus provides a HORN EQ switch
which will boost +12dB at 15KHz with a 6dB/oct slope. This is a
generic curve and work ne with most constant directivity horns,
however ne tune may be needed with 1/3 octave equalizer.
