Do not open the units!

Warning: To avoid electric shock hazard, do not expose this

appliance to rain or moisture. The enclosures may only be

opened by qualified personnel!

Do not install devices in any of the following places:

− where the devices are permanently exposed to direct sunlight.

− near any heat sources and open fire. do not put candles etc. on top of the speaker.

− where the airflow for cooling is blocked. a minimum distance of 10 cm to the heat

sink on the rear of the speaker must be kept.

− where the devices are exposed to high moisture. Objects filled with liquids, such as

a vase, must not be placed on the speaker.

− 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 service 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 connected 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. Furthermore, the power plug must be easily accessible for use at all times.

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 secured 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 properly.

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.

Important

Caution

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 operating 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.

User’s Manual K&F Self Powered Subwoofer Systems ‘SP’

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-ofthe-art integrated driver circuits and Class D power amplifier technology. The extremely lightweight system electronics replace ponderous racks, power amplifiers, controllers, and speaker cables.

Aside from the integrated power amplifier and input modules with controller functions, 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 combinable 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 integrated 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 complete 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

User’s Manual K&F Self Powered Subwoofer Systems ‘SP’

Modes of Operation

− Operations without external controller:

with activated filters (FILTERS ‘ON’), all K&F models in the ‘SP Series’ are combinable 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 recommended 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’

User’s Manual K&F Self Powered Subwoofer Systems ‘SP’

3. Connectors, Controls und Displays

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 connections 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 maintained. 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

Warning

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 beneath, turn the cover sharply in the direction of the arrow.

User’s Manual K&F Self Powered Subwoofer Systems ‘SP’

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 order 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 inner SP speakers can be adjusted downwards accordingly.

When operating with additional bass systems it is very important that the respective 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 always 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 reproduces 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 speakers operating in conjunction with the K&F C2 Controller in the '2-way active' mode is guaranteed.

User’s Manual K&F Self Powered Subwoofer Systems ‘SP’

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 becomes 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:
