1. General Safety Instructions for Using Speakers
Mounting the speakers
To prevent injury, this equipment must be securely placed on the floor or secured to the
wall according to the mounting instructions. Speakers, which are stacked, must be se-
cured with securing straps. Please note that speakers can move as a result of vibrations.
To prevent them from falling from their mounted position, they must be secured prop-
erly.
Speakers may only be suspended by qualified personnel.
Never use signal or power cables for suspending, aligning or securing the systems.
When laying the connecting cables, make sure that nobody can trip.
The speakers must be hung by using at least two of the designated flying points. The
same applies when lifting and aligning the speakers.
Never hang more than two speakers under one another without using the designated
Kling & Freitag mounting devices.
Ensure that all installation connections comply with the applicable safety guidelines and
that the size and strength are sufficient. Further instructions are in our user's manual for
assembly equipment and in the general safety instructions for speakers and assembly
equipment.
For mobile and fixed installations, use only assembly equipment from KLING & FREITAG.
Make sure to observe the included safety and mounting instructions for loudspeakers
and accessories.
Do not install speakers in any of the following places:
−where the speakers are permanently exposed to direct sunlight
−where the speakers are exposed to high moisture
−where the speakers are exposed to strong vibrations and dust.
Damage caused by the speakers' magnetic fields
Speakers are permanently surrounded by a magnetic field, even when they are not op-
erating. Therefore, during transport and placement of the speakers, it is important to
ensure that there is always approx. 1 m between the speakers and magnetic data media
and computer/video monitors.
Protecting the Speakers
When selecting power amplifiers, ensure that they have a sufficient power level. Power
amplifiers with an output level, which is too low, can cause the speakers to overload
(clipping).
Power amplifiers should never be overloaded. When the nominal power of the power
amplifiers is higher than that of the speaker, overload may ruin the speaker.
The input section of a power amplifier may be overloaded without displaying a clipping
signal, e.g. if the headroom of this circuit is too low. We recommend turning the level
controls to the maximum position and to adjust the level before the amplifiers.
The following signals may damage the speakers
−permanent high-pitched signals with high frequency and continuous noise from
feedback
−permanently distorted signals with high power.
−noises, which occur when the amplifier is on while equipment is being connected,
disconnected or switched on.
Preventing hearing damage
To prevent the risk of hearing damage, avoid being too close to operating speakers,
even if the volume level seems to be low enough. In general, volume levels over 90 dB
can cause hearing damage.

3. Instructions for Suspending the Speakers
The speakers may only be mounted by trained specialised personnel.
Please follow the accompanying instructions for speakers and assembly
equip-ment.
Speaker systems, whether single or connected to one another, must always be secured
to a second separate point, even if two rigging points are used for suspending the
speaker system!
Ensure that all connections are secured to prevent their detaching on their own and that
only admissible statically tested and sufficiently sized connecting devices, ropes and
chains are used.
Pay attention to the required safety factors. Please follow the accompanying safety and
assembly instructions carefully as well as the corresponding national safety regulations.
We recommend using the M8 threads only for mounting stand adapters and TV-spigot
adapters. The M10 threads should be used for mounting the CA 1001 tilt brackets only.
Eyebolts can be attached to the M8 and M10 threads in order to suspend the speakers,
if they are dimensioned sufficiently (safety factor 12) and are used as described by the
manufacturer.
Pease note:
The M10 thread inserts can only support weights up to 50 kg each.
The M8 thread inserts can only support weights up to 12.5 kg each.

4. Coverage Angles of the CA Speakers
The CA 1001 can be operated in a vertical or horizontal (i.e. as a stage monitor) posi-
tion. The coverage pattern of the speaker can be adapted to special needs by a 90°
rotatable horn.
The table below shows the coverage angles of a standing speaker: To determine the
coverage pattern of the high frequency horn, shine a flashlight through the front cov-
ering at the level of the horn. You will find a silver stripe that determines the position
and thus the coverage angles of the horn.
DEFINITION:
Standing speaker:
Horn not rotated
85° h x 55° v
Horn rotated
55° h x 85° v
4.1 Changing the Coverage Angles
To turn the horn, follow these steps:
1) Remove the four grille mounting screws on the top and bottom of the speaker with
a 3 mm allen key and remove the grille from the speaker enclosure.
2) Remove the 4 screws securing the high-frequency horn (also 3 mm allen key). Ex-
tract the horn from the top. Should the horn adhere to the foam rubber attached
below, release it using a screwdriver or something similar to gently lever it up.
3) Rotate the horn 90° and screw the horn on tightly again (do not force it!).
4) Screw the grille on tightly.
If the coverage angle needs to be changed often, make sure that the horn is not always
rotated in the same direction, as the connecting cables, when twisted, may causing the
contacts of the driver to become loose.

5. Mounting Instructions for Speakers
Mount the speakers securely. To avoid injury or damage, always be sure to mount the
speakers securely so that they do not fall. Speakers, which are stacked, must be secured
with securing straps. When laying the connecting cables, make sure that nobody can
trip.
The stability of stacked systems (also valid for the use of stands and distance rods!) is
contingent upon the following stability requirement. These conditions must, therefore,
be guaranteed by the user:
Stacked systems may not fall over even if they are inclined by 10° in each direction.
If this requirement is not fulfilled, then it is necessary to take steps to achieve
compliance. Possible measures include strapping it to an appropriate base struc-
ture or fastening it using safety straps.
5.1 Proper Arrangement of the Loudspeakers
Be aware of the fact that the logical targeted alignment of this high quality speaker
system can lead to a significant qualitative increase in the acoustic result. It is not possi-
ble to make generalities about the alignment of specific systems because the room has
a substantial influence on the signal and the audible result.
As a rule, the mid- and high-transducers of loudspeakers should be mounted above the
audience's face value, so that the sound distribution cannot be shadowed.
In many cases it is advisable to mount a loudspeaker higher, so that the sound will be
distributed throughout the room more evenly. Low standing systems result in a greater
difference in volume between front and back seats than higher standing systems.
Please note that this is only a general guideline and the best possible result may vary
from room to room.
To simulate the correct alignment of the speakers beforehand, there are various pro-
grams such as ‘Ease’ or ‘Ulysses’. The Kling & Freitag speaker system data is available for
download on our website www.kling-freitag.de.
The following graphics will assist in making a rough estimate as to the distance range of
the CA 1001. The graphics only take into consideration the sum of the direct sound and
not the influence of the room. Because of this there can, in some cases, be noticeable
deviation.

5.2 Arrayed Speaker Systems (Cluster)
If the loudspeakers are operated through the optional K&F C2 System Controller, we
recommend to turn on the ‘Top Low Cut’ switch for clustered operation. Thus the fre-
quency response for this application can be optimised (see also K&F C2 User's Manual).
When operating the systems without the K&F C2 System Controller in a clustered con-
figuration, the signal level of frequencies below 300 Hz should be reduced by 3-4 dB.
5.2.1 Horn not rotated
*If several 90° systems are clustered, unwanted interference effects may appear. As a
result, we do not generally recommend clustered configurations of CA 1001 systems.
If wide angles are to be covered, we recommend the use of several systems with ro-
tated horns in one cluster.

6. Wiring
The speaker is equipped with two parallel Speakon connectors.
Make sure that all units are switched off and all controls are turned down before con-
necting your CA 1001 systems.
−We recommend the use of high-quality speaker cables provided by KLING & FREITAG.
−For connections to the power amplifier inputs, please use 2-pin shielded microphone
cable with high-quality connectors.
−Avoid ground loops (see chapter 6.2 )
−Please pay attention to the respective pin diagrams in this manual!
−Make sure that the +/- polarity of the speakers at the amplifier is correct. When simul-
taneously using power amplifiers from different manufacturers, be sure to use the
correct specific pin configuration. It may be necessary to modify the pin configuration
on the power amplifiers or on the connectors leading to them.
−Upon completing the wiring, ensure that the connected speaker channels are work-
ing in phase. To do so, use i.e. a phase checker. A phase error can also be recognized
when the connected channels are used simultaneously. During simultaneous use the
bass frequencies become notably quieter or the mid-frequencies such as voices can-
not be located.
−To avoid loss of power, the cables should have a minimum wire gauge of 2.5 mm² -
more for longer cabled distances. A minimum wire gauge can be easily calculated
with the following formula:
If several loudspeakers are connected, the signal can be linked through from one loud-
speaker to the next. Please make sure that the total impedance of the loudspeakers R (Ω)
is not lower than the minimal impedance indicated on the power amplifier:
1/R1 + 1/R2 + 1/R3 + ... = 1/Rtotal

6.2 Avoiding Ground Loops
6.2.1 What is a Ground Loop?
Every component of a P.A. or Hi-Fi System has its own internal 0 V reference (ground).
This point is often connected to the protective earth connector (PE / Ground). If two or
more units are connected to one another with a line level audio cable, there may be a
ground connection through the ground of the power supply cable (yellow-green) as well
as through the shielding of the audio cable. The voltage difference between these two
ground points causes audible interference to come from the speaker.
6.2.2 Avoiding Ground Loops
If there is a loud humming or buzzing after the CA 1001 System has been connected,
then check that a "ground loop" has not been built into the system. Some power am-
plifiers and system controllers are equipped with a "Ground Lift" switch. Set these swit-
ches to the "Lift" position one after the other. If the noise is still audible, check if,
1. the noise is caused by a ground loop before the power amplifiers / controllers
(e.g. mixing console, effects or equalizers).
2. the system or parts of the system are connected to an "unclean" power supply
- meaning one, which is also running large motors, or lighting systems. An "un-
clean" supply voltage, electrostatic and electromagnetic fields can cause a mal-
function.
Please observe the following basic rules:
−Never!!! try to avoid a ground loop by disconnecting or taping the ground
contact at the power connector! Extremely dangerous!
−If possible, only use high-quality audio appliances with balanced signal outputs and
with power cables with PE connectors.
−Use high-quality cables with good shielding.
−The point of ground for all connected components should merge at one central
point. The power connections should lead out in a radial manner from one point
and not be linked from one unit to the next.
−When installing appliances that create strong electrostatic or electromagnetic fields
(large transformers, switch-mode power supplies), maintain some distance from o-
ther audio appliances. In extreme cases, the only solution is to create a completely
independent "audio ground"; in other cases, it is sufficient to connect a filter in
front of the audio equipment.

7. Configurations and Connecting Diagrams
7.1 Operating the Systems without C2 Controller
The CA 1001 systems can be used alone or in conjunction with a K&F subwoofer with
integrated crossover (e.g. SW 112-XO / SW 115D-XO or SW 118E-XO). In this mode of
operation the integrated crossover limits the subwoofer's frequency range.
7.1.1 CA 1001 Systems in Full-Range Mode
This mode of operation is ideal for speech applications and music applications without
the need for a high bass content. Should more bass be needed, the bass level can be
increased between 50 and 80 Hz at the mixing console.

7.2 Operations with C2 Controller
By using carefully adjusted filters (EQ) on special system cards for the CA systems, the
C2 Controller optimises feedback prevention and the frequency response of the spea-
kers.
The controller provides optional bass boost in full-range mode, optimisation for cluster
operation (Top Low Cut switch), high boost and sub-mono functions.
The C2 Controller optimises the operating safety of the speakers and power amplifiers
by using special peak and RMS limiters in Sense Technology:
With other (universal) controllers, the gain of the selected power amplifiers
must be known. The limiter on the C2 Controller, on the other hand, uses a
special control circuit to determine the actual output voltage of the power
amplifiers. The limiter then reduces the input level only when the power am-
plifier actually provides more power than the speakers can handle. The ampli-
fier's gain and the position of the input level control for the power amplifiers
are insignificant for the limiter function of the C2 Controller.

8. Operating the Speakers
−Switch off all equipment and turn down all level controls.
−Wire the CA 1010 Systems according to the wiring diagrams as shown before.
−Upon completing the wiring, ensure that the connected speaker channels are working in
phase. To do so, use i.e. a phase checker. A phase error can also be recognized when the
connected channels are used simultaneously. During simultaneous use the bass frequen-
cies become notably quieter or the mid-frequencies such as voices cannot be located.
−Now switch on the peripheral equipment first (mixing console, effects etc.), followed by
the C2 Controller, if used, and the power amplifiers. Always use the before mentioned
switching order. Otherwise switching noises may damage the system.
−If there is interference, turn off all appliances in the reverse order and check all cable
connections (see chapter 6.2 ).
−Next, turn on the C2 Controller, if used, and the other peripheral equipment and make
sure there is no interference
−Now put a low level signal into the system and check for the correct function of the
system. In doing so, all amplifier input controls need to be turned off again. Now turn on
the control for the left CA 1001 system and check that the correct signal is coming out of
the CA 1001 system.
−With C2 Controller: The Sense LED for the top speaker (i.e. CH 1 TOP signal) of the C2
Controller will light up green at a level of at ca. -40dB. The other channels of the system
are checked in the same way. If the wrong LED lights up or a wrong (i.e., in 2-way active
mode, low signal from a high frequency speaker) or distorted signal occurs, then there is a
mistake in the wiring.
−Your system should now be ready for operation.
−Turning down the input level controls may not always prevent distortions in the input
section of the power amplifier, especially if this section has a relatively low headroom.
A clipping signal may not be displayed by the clipping indicator then. To prevent sig-
nal interruptions or damages to the speakers, turn the level controls of the power
amplifier to the maximum position, if possible. The output level of the mixing console
or the controller should be set to a level that doesn't overload the power amplifiers.
−When turning off the system, the input controls for the power amplifiers should be
turned down first followed by the power switches of the amplifiers. After that, the
other appliances can be turned off.
−The crossovers of the CA 1001 systems are equipped with protection circuits for the
high frequency driver and the crossover itself. These circuits cut off the signal current
when highly overloaded. If the high speaker turns off, reduce the volume. After a few
seconds, it will turn back on automatically.

10. Touching Up Damage to Paint / Changing the Front Foam
Although the PU structured paint used by KLING & FREITAG is impact proof and ex-
tremely resistant, we recommend using protective coverings or cases to help avoid da-
maging the paint during i.e. continuous mobile use. If paint damage occurs despite
these precautions, it can be touched up by using commercial acrylic paint in the appro-
priate RAL colour of the speaker.
To replace the filter foam, send the front grille incl. foam to KLING & FREITAG GmbH.
Upon payment for expenses, the grille with the new covering will be returned.
