−where the devices are exposed to strong vibrations and dust.
Power Supply
Before connecting the AC power cable of the SP speaker, please check if the available
voltage is compatible with the operating voltage as indicated on the unit. If this is not
the case, then the unit needs to be adapted by the manufacturer or an authorized ser-
vice centre. If the unit is not compatible with the available voltage, it should never be
connected! This could irreparably ruin the SP speaker.
Make sure that the power outlet supplies a ground connector, which must be con-
nected to the unit via the PE conductor of the power cord!
All equipment, which is connected together using signal cables and has a connection to
protect ground, must be connected to a common protective earth. If not, there is a risk
of an electric shock or the destruction of the connected equipment.
The power plug must always be used to disconnect from the power supply. Further-
more, the power plug must be easily accessible for use at all times.
Protection of Electrical Cables
Power cords should be laid in such a way that they are protected against footstep dam-
ages, tensile strain and against being trapped.
Transportation
When transporting the equipment, make sure that it is protected from vibrations.
Cleaning
The equipment should only be cleaned with a damp cloth when it is not plugged in.
Pauses in Use

The user should not perform any maintenance work on the equipment other than that
which is described in this manual. Repairs should be executed by a qualified service
technician only.
In the following cases, the unit should be serviced by an authorized technician only if:
−the power cord or the mains connectors have been damaged.
−objects or liquids have gotten into it.
−it was exposed to rain.
−it doesn't appear to be functioning properly.
−it has fallen down or the enclosure is damaged.
Mounting the speakers
If the weight of the speaker exceeds 25 kg then it is necessary for two people to carry it.
To prevent injury, this equipment must be securely placed on the floor or secured to the
wall according to the assembly 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 cables or power cords 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.
Unwanted interference
RF interference on the power cord or on the line signal cables may lead to unwanted
sound interference.
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.
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 SP speaker is connected 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.

2. Introduction SP Loudspeakers
'SP' denotes a new option for selected models in the K&F range of loudspeakers.
Based on selected K&F speaker systems, the ‘SP’ models are equipped with state-of-
the-art integrated driver circuits and Class D power amplifier technology. The ex-
tremely lightweight system electronics replace ponderous racks, power amplifiers,
controllers, and speaker cables.
Aside from the integrated power amplifier and input modules with controller func-
tions, the full-range systems possess a passive crossover so that the advantageous
features provided by the K&F passive technology (all-pass filter, protection circuits)
remain usable. The frequency separation for the subwoofers is controlled by an active
110 Hz low pass filter.
Integrated phase optimisation allows for all systems in the ‘SP Series’ to be combin-
able with one another. With this, the ‘SP’ speakers, when the filter section is switched
off, have a completely comparable sound to the corresponding versions without inte-
grated power amplifier technology. Operations using the K&F C2 Controller are also
possible, which is, for example, appropriate for combined applications with equivalent
passive systems or for the use of C2 Presets (clustering = Top Low-Cut, Bass-Boost
etc.).
Operating the ‘SP Series’ is incredibly easy: The full range systems transmit the com-
plete frequency spectrum. If necessary, the ‘SP’ subwoofers in parallel operations can
provide an additional bass boost.
The Input Module
−Line signal input
−Limiter section (feed-forward RMS-limiter and peak limiter in feed-back design).
−High pass filter, 45 Hz tops, and 32 Hz subwoofers
−Low pass filter 110 Hz (subwoofer systems only)
−System specific, switchable frequency equalisation (‘FILTERS ON/ OFF’) controllable
by a covered switch on the connecting terminal
−Phase correction
−Level adjustment (countersunk level control on the connecting terminal)
The Amplifier Module
−1 x, or 2 x 1 kW Class D state-of-the-art power amplifier
−Minimal dimensions (speaker dimensions of the models without the ‘SP’ module are
retained)
−Low weight (weight increase of 2.5 / 4 kg as compared to systems without the ‘SP’
module; and with the Line 212 --- SP, the weight even stays identical)
−High efficiency enables convection cooling, because of which bothersome fans are
unnecessary
−High fidelity (even in high frequency range) and a large power band width resulting
from impedance optimisation

Modes of Operation
−Operations without external controller:
with activated filters (FILTERS ‘ON’), all K&F models in the ‘SP Series’ are combin-
able with one another by simply linking the signal from one speaker to the next.
−With optional K&F system controller*:
with system plug-in cards via the K&F Controller C2 or an Audio DSP*:
−if used with BSS Soundweb, FDS 366, 336, 334, and XTA DP 226, 224, K&F sys-
tem parameters are available upon request
* The operation of the K&F 'SP' models with Controller C2 or Audio DSP is recom-
mended for uses in which special filter pre-sets are advisable, i.e. in combination with
passive systems of the 'CA Series', in cluster operations (top low cut), when bass and
high boost are necessary, adjustment to the room acoustics (EQ), etc.
The following K&F 'SP' speakers are available:
Full-range systems: CA 1001 - SP,
CA 1201 - SP,
CA1215-6 - SP, CA 1215-9 - SP
CA 1515-6 - SP, CA 1515-9 - SP
LINE 212-6 - SP, LINE 212-9 --- SP
Subwoofers: SW 112 - SP, SWi 112 - SP,
SW 115E - SP, SWi 115E - SP,
SW 118E - SP, SWi 118E - SP,
SW 215E - SP, SW 215E - SP ‘Suspension’

1) LINE IN and LINE OUT (+6 dB)
Electronically balanced input and output connectors. Use the XLR female connector
(marked 'IN') as input. The parallel-wired XLR male connector (OUT) is for connec-
tions to further 'SP' loudspeakers.
2) GROUND LIFT
When the ‘Ground Lift’ switch is set to LIFT, pin 1 of the LINE IN connector (ground)
is not connected to the chassis ground of the integrated amplifier module. The
ground connection between LINE IN (XLR male) and LINE OUT (XLR female) is main-
tained. The use of the 'Ground Lift' switch is sometimes necessary in dealing with
hum problems (see chapter 7.1 )
Never tape over the protective earth on the plug --- danger to life!
3) PROTECTIVE COVER
The protective cover prevents unwanted adjustment of the gain control and filter
ON / OFF switch. The cover has a snap-in lock. In order to reach the controls be-
neath, turn the cover sharply in the direction of the arrow.

4) GAIN CONTROL (± 6 dB)
a) The gain control can be used to adjust the input level of the amplifier module
by ± 6dB. It serves to balance the volume levels of the various systems. In or-
der to avoid overloading the input circuit or the mixer’s output circuit, it
should normally be set in the case of K&F full-range systems at 0 dB (centre
notch setting).
b) When operating with C2 Controller, set the input level of the amplifier mod-
ule on the C2 Controller (Input Gain). The gain control on the SP speaker
should be set at 0 dB (centre notch setting). One exception to this rule is a
cluster arrangement, in which the inner speakers should be set at a lower
level than the outer ones. In this case the level of the gain control on the in-
ner SP speakers can be adjusted downwards accordingly.
When operating with additional bass systems it is very important that the respec-
tive volume levels between the top speakers and the bass systems are correctly
balanced. To this end the sound engineer should check the volume levels during
the set-up and adjust them accordingly. When setting up a system without C2
Controller this adjustment should be carried out using the gain control of the SP
subwoofer (use gain control of the top speaker if not sufficient); in the case of a
system with C2 Controller use the 'Sub Gain' control on the C2 Controller.
Please note that the position of a bass speaker is crucial for its actual sound level. A
bass speaker, which is on the floor, can be a few decibels louder than a flown bass
system because of the floor reflections. Because of this, a sound engineer must al-
ways fine-tune the system using the corresponding level controls.
5) FILTERS ON / OFF (High Pass / Low Pass / Equalizer)
This switch turns the filter in the SP module on ('ON'), or off ('OFF').
a) The switch should always be in the 'ON' position when the speakers are being
driven without C2 Controller.
b) The switch should always be in the ‘OFF’ position when the speakers are being
driven with C2 Controller.
The filters consist of:
−high-pass: protects the speakers against mechanical stress due to frequen-
cies outside the speaker's frequency range (protection against subsonic
frequencies)
−low-pass (subwoofers with SP-module only): Only frequencies below 110
Hz can pass the low pass filter. In this way, the bass speaker only repro-
duces the intended frequencies.
−EQ: filter for basic equalization, optimizing the frequency response of the
speaker systems.
Furthermore the SP filter module has a phase alignment, which prevents loss of
certain frequencies due to phase shift between mid-high and bass systems.
Thus the combination of all available K&F mid-high SP systems with all K&F
bass SP systems is possible, and 100% phase compatibility with all K&F speak-
ers operating in conjunction with the K&F C2 Controller in the '2-way active'
mode is guaranteed.

6) LED POWER ON (GREEN) and LIMIT / PROTECT (RED)
The LED is dual-purpose:
a) When the LED is green, the speaker is connected to the supply voltage and
ready for operation
b) The LED will turn red if…
…the input signal is so high that the internal limiters reduce its level.
The limiters consist of a peak limiter, which limits the peaks of the signal,
and an RMS / thermal limiter, which continuously regulates excessive levels.
During normal operation the red light may occasionally illuminate briefly. It
does indicate that the level peaks are limited by the limiter circuit. The peak
performance of the speaker has then been reached.
Should the red light come on more frequently or remain illuminated, the
output level of the mixer should be reduced. When speakers with and
without SP module are in operation simultaneously, the gain control on the
SP speaker can be turned down, provided the level is sufficient for the
other power amplifiers. The limiter protects the speaker from damage due
to excessive levels.
c) The LED stays permanently red, if…
…the protection circuitry of the integrated power amplifier cuts in and as a
result no further signal reaches the speaker (Protect Mode).
The protection circuitry switches off the integrated power amplifier,…
−…if the temperature of the amplifier module is too high. As soon as
the temperature falls below the critical value, the amplifier module is
switched on again automatically. Excessive temperatures can be
caused for example by inadequate ventilation of the heat sink. Make
sure that the air vents are not covered or positioned directly against a
wall.
−…if the output impedance is too low or in the case of a short circuit,
caused for example by a defective chassis or a faulty component on
the crossover.
−…if the amplifier has an internal fault. The SP amplifier module checks
that all is functioning correctly during operation. As soon as a fault be-
comes apparent the module switches into protect mode. If only one
module of the SW 215E has a fault, the input signal is attenuated by
70 dB, to prevent damage to the other module.
Measures to be taken when LED is red:
Fault Measure Function
LED remains red or flickers
continually during opera-
tion
Reduce output level on mixer until LED
goes out or flickers only occasionally.
Limiter
No output signal, LED
shows red in spite of re-
duced mixer level.
Allow to cool. The amplifier module
switches itself on after a few minutes.
Provide sufficient ventilation. Provide

6. 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.
Stacked systems may not fall over even if they are inclined by 10° in each direction.Stacked systems may not fall over even if they are inclined by 10° in each direction.
Stacked systems may not fall over even if they are inclined by 10° in each direction.

6.1 Using the Mounting Accessory ‘Distance Rod’
The SP subwoofer is equipped with a threaded flange (M20) on the top of the enclosure
for mounting the optionally available distance rod (not on the SWi versions).
All K&F top speakers with a mounting flange or stand adapter may be mounted on the
distance rod. Only use authentic Kling & Freitag distance rods and stand adapters. We
can only guarantee safe operations when these parts are used.
When a top speaker is mounted on the subwoofer using a distance rod, the stability of
the speakers is reduced. Please follow the stability requirements in chapter 6!
When re-positioning after set-up, remove the upper speaker mounted on the distance
rod first.
Special note for the model SW 112
A top speaker with a maximum weight of 28 kg (i.e. CA 1201) may be mounted on this
speaker using a distance rod. Speakers, which are heavier than 28 kg, may not be
mounted on the distance rod flange and must be mounted on an additional speaker
stand.

7. Wiring
Before connecting your SP system, be sure to switch off all connected appliances and
turn down all level controls.
−We recommend the use of high-quality cables provided by KLING & FREITAG.
−For connections to the line level inputs, please use 2-pin shielded microphone cable
with high-quality connectors.
−Avoid ground loops (see chapter 7.1 )
−Make sure that the pin assignment of the line level connectors is correct (2 + / 3 - / 1 ┴).
7.1 Avoiding Ground Loops
7.1.1 What is a Ground Loop?
Every component of a P.A. or Hi-Fi System has its own internal 0V 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.
7.1.2 Avoiding Ground Loops
If there is a loud humming or buzzing after the 'SP' System has been connected, then
set the "Ground Lift" switches on the rear of the 'SP' speakers to the 'Lift' position
(chapter: 3 / section 2).
If the noise is still audible, check if
1. the noise is caused by a ground loop before the speakers (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 inter-
ference.
Please observe the following basic rules:
−Never !!! try to avoid a ground loop by disconnecting or taping the ground
contact at the 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
other 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.
