XETEC 3-KANAL FULL ACTIVE
CROSSOVER TECHNOLOGY F.A.C.T. F-3
With the feature woofer highpass it is possible to adjust the lower woofer
x-over frequency between 45 Hz to 250 Hz.Middle position is 115 Hz.
The option bass highpass defines the lower x-over frequency, that means
the frequency the bass range starts. (22 Hz-160 Hz) center position is 90 Hz.
The option bass lowpass defines the upper frequency, that means the
frequency the bass range ends. Middle position is 90 Hz. All filter
characteristics are 12 dB per octave.
The switch mode front / rear is exclusively for the use of carEQfi module,
and provides selection whether the F-3 is used for a front or rear system,
because the carEQfi modules are always for 4- channel use.
With the features system level , tweeter level and bass level the gain
of each channel can be adjusted in order to match the different efficiencies of
the drivers.
All features of active crossover show the conceptional
advantages of active loudspeaker management :
- All power amps connected to only get the user
defined frequency range, and must not reproduce the whole frequency
range that would be filtered in a passive crossover. This relieves the
power amps and increases the systems efficiency.
- With the you get an open, modular full active
crossover concept, which improves any loudspeaker solution.
If you operate with a carEQfi module, you
get an outstanding performance perfectly adapted to your vehicle·s
acoustical environment.
- The tweeter phase shift range can be adjusted variably and separately
for each channel. This option would be impossible in passive crossover
solutions.

SAFETY
Before you make any connection,the battery must be
disconnected!
A main fuse must be installed into the +12V wire within
+ the first 12" from the + terminal of the battery
(insurance regulation!).
The fuse in the power line only protects the device itself,
not the battery and the car!
2

Always use an in-line fuse in the +12 V power cable in max. 12"from the
battery·s + terminal (value must meet the current requirements of the whole
sound system,minimum value is 60A).
1.5 The last connection is the remote wire.The headunit must always be
turned off during this connection,as it might be damaged when
remote output is shorted to ground!
1.6 Now you can reconnect the battery and insert the main fuse
into the power cable fuse holder.
For safety reasons, the has to be mounted properly
and fixed to the car body. Please fix the device using the screws that come
with your product.
Be careful when drilling holes, there might be wires, fuel lines or the gas tank
behind a wall!
Before you make any connections,always disconnect the battery!
1.1 First of all, connect the RCA cables coming from the radio/headunit
to the respective inputs of your .Always run signal cables
in a distance to power cables and the vehicle·s factory wires to avoid
induction of noise.
1.2 Now connect the signal cables from the outputs of to the
corresponding inputs of your power amplifiers. Make sure that all
power amplifiers are in fullrange or bypass mode , that means
that all filters are off, because otherwise the filter curves of
would be overlapped.
1.3 Next step is the ground connection. Check for a good grounding
point using your vehicle·s chassis. Make sure that this point has good
electrical contact! Some parts of the chassis might only be glued
and have no contact to battery (-). Run all ground cables of the
system to this point to avoid alternator whine and other noise.

1.4 In the next step, the +12 V cable has to be connected to the (+)
terminal of the battery. Always be careful not to run this cable
around sharp edges,the insulation might be damaged. For holes always
use grommets!
1.5 Always use an in-line fuse in the +12 V power cable in max. 12" from
the battery·s + terminal (value must meet the current requirements
of the whole sound system,minimum value is 60A).
1.6 Now you can reconnect the battery and insert the main fuse into the
power cable fuse holder.
2.1 System level / push tweeter
This function adjusts the system volume. If you keep the switch
pressed you can adjust the tweeter level in relation to the woofer
level.
2.2 X-over Freq
Adjusts the x-over frequency between tweeter and woofer.
Center position is 4.1 KHz,adjustment range is 2.3 KHz - 6.5 KHz.
2.3 Phase tweeter left,Phase tweeter right
This feature provides phase delay correction separately for each
channel. Phase correction ensures that tweeter and woofer signals
reach the ear coherently.
This results in a dynamic and spatial sound reproduction.
2.4 Woofer highpass
With this control the upper frequency limit of the bass channel can
be adjusted from 45 Hz to 250 Hz.Center position is 115 Hz.
2.5 Bass level
This feature adjusts the level of the bass channel.
2.6 Bass highpass
The option bass highpass defines the lower x-over frequency, that
means the frequency the bass range starts at. (22 Hz-160 Hz) Center
position is 90 Hz.
Caution:Always replace fuses with same value. Higher values may
cause damage to your amplifier,battery or car!

2.9 Ground lift
The ground lift jumper on the board near the inputs are normally set
to ground connect (unbalanced).
In case of disturbances, as alternator noise, you take the alternative
position called grond lift (balanced) to eleminate those distur-
bances.
2.10 Woofer EQ jumper (near to woofer highpass (2.4) adjuster)
In delivery status these jumpers are in position Woofer EQ .
This causes a little sinking in the upper middletone range, which is
normally overemphasized by most woofers, because of their voice
coil inductance. In the position EQ off the woofer signal passes as
usual.
2.11 Option carEQfi module carEQfi is a patented signal processing and
comes in a module. carEQfi modules are available for various car
models.Basically they are a pre-adjusted equalizer which compensates
the typical acoustical environment in a car, determined by several
resonances and reflections. Using carEQfi avoids complicated
measurements, and is a plug-and-play improvement for every sound
system.
Who needs crossovers?
The ideal loudspeaker is working Fullrange , that means, it can reproduce
all frequencies with the same quality.A dream.This problem is usually solved
dividing the audio spectrum into frequency ranges that fit specially designed
speakers that are able to reproduce at least a certain part of it:
Woofers for low and tweeters for high frequencies. Together they are
supposed to cover the whole spectrum then
But a tweeter is unable to reproduce low frequencies, as those have high
energy and it will be immediately destroyed, and a woofer is unable to
reproduce high frequencies above a certain limit due to it·s inertia, it simply is
too slow.
Please note:both jumpers must be in the same position!
Please note:both jumpers must be in the same position!
So, a new problem is caused. We must try to feed the woofer and tweeter
with only the frequency spectrum they easily can handle. Thus we use
a crossover network , a frequency divider or separator called crossover.
That causes the third problem: Passive crossovers are used behind the
amplifier and thus need big components to handle the amplifier·s output
power.
Our more intelligent way is, to accomplish the separation of high and low
frequencies BEFORE they pass the amplifier. This way the possibilities of
correction and perfect matching in crease significantly.
This principle is called active mode , and we have re-defined it in our
concept.
Just keep your speakers ! (...and activate them with F.A.C.T.fi F-3!)
Why active ?
Active crossovers offer many options to correct and positively influence the
signal. So, you can increase the performance of your existing passive system
enormously.
1. Passive crossovers cause rather high losses due to their high
impedances compared to the output resistance of the amplifier.
Even the good damping factor of a high quality amplifier that might
be 200 will be reduced by the passive crossover·s losses to ridiculous
4,8 at the woofer and even a damping factor of 1000 will be
reduced to 4,9 finally . and, by the way, 10.000 will also result in
only around 4,9! The damping factor is the measure for the control
of the amplifier on the connected speaker. Minimum requirement is
>100
2. Damping factor is very expensive,save it and use !
3. Passive crossovers never match the speakers sufficiently. Their
component·s tolerances around +/- 10 20% successfully prevent
that. Passive components like resistors, capacitors and inductors are
only available in certain values and have to be used by compromise.
4. The Tweeter Level is only roughly adjustable in passive x-overs
(commonly +3, 0, -3 dB) that·s more than coarse and far away from
the needs or even fine-tuning .
5. The system·s phase relations are fully determined by chance
depending on the mounting locations of the speakers, their distance
and relative angles. That means that phase adjust of woofer and
tweeter cannot be influenced at all using passive x-overs.
6. So called subwoofer- and midbass-crossovers cause the
highest losses caused by component·s impedances and high energy.

The advantages of passive crossovers:
They are free and come with the speaker set.
Simple and comprehensive due to no-features .
No special knowledge required.
Quick installation.
An average result can be accomplished easily.
The advantages of :
Every single speaker, woofer,tweeter,midbass,has it·s own amplifier.
No losses caused by passive components.
The amplifier·s damping factor can take full effect.
The crossover frequency, tweeter-, woofer- and system level can be
adjusted continuously instead of coarse Steps.
Left and right tweeter can independently and individually adjusted
in their phase.This is impossible using passive crossovers.
