Product Description
Hardware K&F CD 44 Digital System Controller
The signal processor CD 44 is a digital 4 in 4-way speaker controller that can process both analogue and digital signals in the AES/EBU format up to 192 kHz.
The controller is equipped with the finest AD and DA state-of-the-art converters as well as 3 micro-controllers and 8! integrated signal processors (DSP). It not only offers excellent audio results, but also a multitude of special features and novel functions:
Multi-level memory concept for parameter management
The parameter sets for almost all K&F speaker systems are saved in the form of macros in the device (the so-called ‘LSBlocks’). They can be copied as a complete set of data and independently of one another into each of the 4 output channels.
The specification of one K&F phase reference for multi-way operations is advantageous because of its high level of compatibility. Without requiring phase adjustments, the various K&F tops can be combined with all K&F subwoofers.
Additional LSBlocks ‘Flat’ facilitate the integration of third-party products (with limitations) or the processing and linking of signals to speakers with integrated filters and amplifier electronics.
14 pre-configured routings allow every reasonable configuration from up to 4 different input signals to the 4 output channels.
Frequently used combinations of routings and ‘LSBlocks’ can be saved along with further parameters (such as Gain / Delay / PEQ) in up to 64 set-ups.
Two-step limiter concept
Two limiters work in each of the 4 output channels. A quick reacting “peak limiter” limits the peak level and, thus, the cone excursion of the connected speakers is kept at non-critical levels.
A slow reacting ‘RMS Limiter’ reduces the level when there is a risk that the permissible average power will be exceeded, thus resulting in the voice coils overheating.
The pre-set values have been established in extensive series of tests. With excellent sound qualities, they provide an outstanding compromise with regard to the peak levels and protection of the speaker systems.
Automatic determination of gain using sense technology
The CD 44 calculates the gain of the connected amplifiers in real-time and automatically corrects the limiters’ thresholds as soon as the gain of the connected amplifier should be changed (i.e. by using the input potentiometer or similar). Compared to conventional devices this results in a clearly improved reliability when adjusting the limiter thresholds.
Limiter reduction
The preset limiter thresholds can be reduced in fine increments for specific purposes. This function is advantageous when the connected speakers are to be subjected to a particularly long-lasting high load. In this case, the reduction of the limiter thresholds reduces the maximal thermal and mechanical stress, thus significantly extending the product life of the speakers.
Furthermore, these functions can also be used to limit the sound levels of the speakers.
The integrated limiters and the function ‘Limiter Reduction’ can also be used for speakers with integrated amplifier electronics. For this, the gain values of the utilised power amplifiers can be edited manually in the CD 44.
Operating with 'Shortcut' buttons
Four buttons with ‘Shortcut’ functions make it possible to directly jump to often-used functions without having to navigate through the menu. By pushing these buttons repeatedly, you access the functions of all input and output channels.
In doing so, the functions ‘Gain’, ‘Delay’, ‘Filter’ and ‘PEQ’ can be quickly and easily adjusted.
Additionally, the LEDs which are integrated into the respective buttons indicate if these functions have been changed as compared to the original settings.
31 Band One-Third Octave EQs
A separate 31 band one-third-octave EQ is assigned to each of the CD 44’s four input channels. Up to 16 different EQ setups can be saved and administrated in an individual EQ setup library. These EQ setups can be loaded in addition to the setups.

4-pin Speakon connectors. All Kling & Freitag speakers that are, by default, connected with 1+ / 1- can be plugged into these connectors.
Caution: The connectors with the position numbers 1 and 3 are connected differently than the connectors with the position numbers 2 and 4.
Interchanging the speaker channels may ruin the speakers in some cases
(Example: high frequency speaker on bass output).
(1) This output connector supplies the signal for the speaker channel 1. In this connector, the pin 1+ is bridged with 2+, the pin 1- with 2-. The signal for channel
1 is, therefore, applied to 1+ / 1- as well as 2+ / 2-.
(2) This output connector transmits signals for 2 speaker channels:
The signal for the speaker channel 2 is applied to 1+ / 1-.
The signal for the speaker channel 1 is applied to 2+ / 2-.
(3) This output connector supplies the signal for the speaker channel 3. On this connector, the pin 1+ is bridged with 2+ and pin 1- with 2-. The signal for channel
3 is, therefore, applied to 1+ / 1- as well as 2+ / 2-.
(4) This output connector supplies signals for 2 speaker channels:
The signal for the speaker channel 4 is applied to 1+ / 1-.
The signal for the speaker channel 3 is applied to 2+ / 2-.
(1) + (3) If you want to use the CD 44 to operate bass speakers whose 2 chassis are controlled by separate supply lines (ACCESS B5 and ACCESS B10), then you should use these connectors for these bass systems in order to control the speakers via a common channel without an adapter (CH1 or CH3). Fore more
information see configuration example on page 46.
(2) + (4) If you want to use the CD 44 to operate ACCESS tops T5 and T9 or Sequenza
10 N / W with separate high- and mid-range controls, you should use these connectors for the tops because these systems must be controlled using 2 channels.
In order to implement a one-cable system (control of a top and bass via a 4core supply cable), you must use these connectors, because the top and bass must be controlled using 2 different channels.

(5) Signal input connectors: INPUT 1 through INPUT 4, 3-pin XLR female connectors.
These signal input connectors can be used both for analogue and for digital signals, in accordance with the AES / EBU specifications. You must make the selection in the device about the type of signals it is being supplied with: digital or analogue. (Further
information on pages 26 and 61). Select the type of signal source before
connecting the signals!
Important

Upon delivery, the controller is pre-programmed for the use of analogue input signals.
These inputs correspond to the connectors on the rear panel and are wired in parallel with them.
Do not assign the inputs on the front and rear panel simultaneously. This may lead to malfunction or damage of other appliances!

Analog (Default, Flipped or 1&2 Mix):
Pin configuration: 1 = ground / 2 = + / 3 = - . The LINE inputs are electronically balanced.
The nominal input level is +6dBu (1.55Vrms).
The maximum input level is +18dBu, that is, the peaks in the signal must not exceed
+18dBu (6V). b)

(Default, Flipped or 1&2 Mix)
The input connectors 'INPUT 3' and 'INPUT 4' are not used in this setup!
Pin configuration: 1 = ground / 2 and 3 = digital signal.
To avoid unexpectedly high volume levels, reduce the controller’s input gains to a value of approx. ---40 dBu before supplying these connectors with a digital signal directly from an audio source, and then adjust the level to your needs!

SIGNAL PRESENT, LIMIT
a)
SIGNAL PRESENT:
These LEDs light up green when a signal with a level higher than ---45 dBu is present at the XLR output connectors on the rear of the unit (Out 1 through Out 4). b)
LIMIT:
The output level of the controller is limited. As a result, the controller avoids an output level of the power amplifiers which is too high for the connected speaker.
These LEDs light up red as soon as the output level of the relevant channel comes under the influence of the controller’s limiters. A gently engaging RMS limiter and a fast peak limiter limit the output of the power amplifiers virtually inaudibly to the maximum permitted level. If the red limiter LEDs light up frequently, the level of the input signal should be reduced on the signal source preferably (i.e. on the mixing console).

AMP RETURN / SENSE
1+ / 1- = CH 1
2+ / 2- = CH 2 and
1+ / 1- = CH 3
2+ / 2- = CH 4
You must plug the amplified output signals of the power amplifiers into these connectors (speaker signal).
The amplified output signals which are connected here are required by the limiters in the controller (sense signal). The signal is routed to the Speakon connectors CH 1, CH 2, CH
3 and CH 4 on the front, so that the speakers can be connected.
If the connectors 'AMP RETURN / SENSE' are not connected to the power amplifiers, then there is a risk that the speakers will be ruined. Exception: When using the CD 44 with SP speakers, the AMP RETURN / SENSE inputs are not used, as the SP speakers are equipped with their own limiters. More about this in
chapter SP Speakers on the CD 44 on page 55.

Making Adjustments and Navigating Through the Menus
In this chapter, we will give a detailed description of how to make adjustments or to save or cancel changes and how to navigate through the menus.
9.1 The Use of the Shortcut Buttons
The shortcut buttons help you to make quick adjustments without having to navigate through the menu. We therefore recommend that you solely use the shortcut buttons and not the menu navigation when making adjustments to the parametric filters (PEQs), the input and output gains, as well as to the input and output delays.
Adjustments that are made using the shortcut buttons do not have to be confirmed by pushing the exit button. After approx.10 seconds, the adjustments made to the device are confirmed automatically.
9.1.1
Parametric Filters 'PEQ' + SEQ LShelv (Filter A Button)
By pushing the Filter A button, you access the parametric Filters (PEQ).
Using the menu navigation, the PEQs can be accessed at In
→
Filter 4.
Up to 4 parametric filters per input channel serve to equalise the system, i.e. to adjust the speaker frequencies to the room conditions. They can also be used to eliminate the feedback during monitor uses. The PEQs are saved with the setup.
In the PEQs, the parameters for filter type, gain, frequency, and Q-factor can be adjusted.
If a filter is activated (not set at BYP = bypass in the editing mode), then the blue LED of the filter A button will light up.
If you change to another type of filter, the Q-factor automatically sets itself to a value of 0.707. This safeguards against unexpectedly high levels which might be caused by a Q-factor that is too high. When you have changed the type of filter, always make sure if a Q-factor of 0.707 meets your needs and correct it, if necessary.
Explanation of the filter types of the PEQ:
The parameter "Gain" is adjustable in steps of 0.1, from -96 to +24 dB (independent of the input and output gains). The parameter ‘Gain’ has no effect on the filter types 'LowP',
'HighP' and 'AP.
The parameter "Freq" is adjustable in 1Hz steps, from 10Hz to 20kHz.
1.
Bell = Bell Filter
This filter increases certain frequency ranges (positive gain) or attenuates them
(negative gain).
The gain determines the maximum or minimum level increase or attenuation of the filter (in the graph: increase of

This ‘bell’ is logarithmically symmetrical relative to the selected frequency (in the example: 1000 Hz).
The Q-factor defines the quality of the filter. In doing so, it determines the width of the frequency range which is to be increased or attenuated. The higher the Q-factor, the narrower the frequency range. A lower Q-factor thus has a wider range.
"Q" is adjustable in steps of 0.001 from 0.2 to 20.

The Q-factor determines the slope of the filter.
Normally, shelving filters are used with a Q-factor of up to 0.707.
With Q-factors higher than 0.707, the selected frequency is increased and an area above this frequency range is attenuated correspondingly. The shelving filter is, thus, normally only used up to Q
0.707.
A Q higher than 0.707 may result in unwanted sound changes (see graph).

SEQ LShelv setting for exemplary speaker arrays (recommended values):
Depending on the spatial geometry and other application-specific factors, the values that must actually be set in practice may vary from the below-mentioned recommended values.
This is why the sound engineer should always fine tune the output gains when setting up the system.
The filter depth and the cut-off frequency of the low shelving filter depend on the amount of speakers. The larger the number of speakers
th e stronger the attenuation off frequency
The attenuation can be set from 0 to -14 dB, the cut-off frequency from 250 Hz --- 1.2 kHz,

Explanations for the speaker-specific filters:
−
Presence: Mid boost. To achieve sound compatibility with the SONA 5 without the CD
44, switch on this filter along with the High Boost Filter.
−
High Boost SONA 5: slight increase using a Shelving Filter. To achieve sound compatibility with the SONA 5 without the CD 44, switch on this filter along with the
Presence filter.
−
High Boost: To compensate high-range attenuation over long distances for tops.
Sequenza 10 N / W: The high boost filter should only be switched on for speakers whose main beam is directed towards audience sections that are approx. 40 m or further away. Normally, this only applies to a few of the upper speakers.
−
Cluster: To compensate undesired frequency additions in the low-mid range for monitor and cluster usage (cluster = several speakers placed directly next to one another). o
Switch on the Cluster Filter for tops if you wish to operate several tops (cluster) next to one another or if you place the top on the floor as a monitor. This reduces the frequency additions in the low/mid range that result from clustering the speakers
(with one another or on the floor). o
If you operate several tops aligned next to one another (cluster), then there is an addition of certain frequencies that can interfere with the sound results. This frequency addition is compensated by the cluster filter. If these clusters are positioned on a subwoofer, then the phasing between the tops and the subwoofer can be improved when both ways run through the same filter, in other words: when the cluster filter is also switched on for the subwoofer.
−
Bass Boost: To boost the bass for usages with the ACCESS B10 speakers.
−
Straight (Sequenza 10 N / W only): The straight filter serves to harmonise the balance of the upper-mid range between shorter and larger listening distances. It is preferably used for speakers whose angle to the other speakers is 0°, 1° or 2.
The Straight-Filter must be switched in both paths of the speaker, so in the SEQ 10LF/HF
(FR or LCut) and the SEQ 10LF (FR or LCut) to 'ON'.
−
Combi Mode: Switch on this filter if you want to use the subwoofer SEQUENZA 10 B with K&F tops other than the SEQUENZA 10 N or SEQUENZA 10 W.

Input and Output Gains (Gain Button)
Hardware K&F CD 44 Digital System Controller
Pushing the GAIN button allows you to directly access the input and output gains without having to navigate through the menu.
After you push the GAIN button, the first possible setting is for signal input (input gains). If you push it repeatedly, you access the output gain.
If one of these gain values is not zero, the red LED on the GAIN button lights up.
How high a gain can actually be set depends on, among other things, if and how high an output gain is already preset in an LSBlock. The output gains saved in the LSBlock are neither visible nor adjustable. Depending on the LSBlock, these output gains have values between
0dB and +5.3 dB. It is, therefore, possible that the user can set the gains accordingly lower than the otherwise possible +24 dB. We generally advise against selecting such high gain values.
a) The Input Gains
Using the menu navigation, the input gains can be accessed at
In
→
Input1 through Input4
→
Gain.
Depending on the output gain and the previously used gain in the LSBlock, the input gains can be set between -96 dB and +24. The sum of the input gain, the output gain, and the LSBlock's gain can not exceed +24 dB.
Adjustments to the input gains may be necessary if, for example, the limiter LEDs light up often. In this case, the input gains can be reduced.
If the input signal is too weak, use the input gains to increase it.
You can find an overview of the input gain settings on a prompt, subsequently referred pushed the EXIT button several times.
You can find more detailed information about this in the chapter I beginning on page 19
b)
The Output Gains regulate the level of the individual signal outputs (OUT 1 through OUT 4).
You can access the output gains at
Out
→
Depending on the input gain and the gain previously used in the LSBlock, the output gains can be set up between -96 dB and +24. The sum of the input gain, the output gain, and the LSBLock's gain can not exceed +24 dB.
The output gains are used for, for example:
− level adjustments for different zones of sound coverage.
− level adjustments between top speakers and bass systems. When the number of arrayed bass speakers is doubled, the level increases by up to + 6 dB (+3 dB efficiency and +3 dB by doubling the power amplifier output). Due to their directivity, the level of the top speakers does not increase correspondingly.
Furthermore, a flown bass speaker can be several decibels quieter than a bass system which is standing on the floor (because of floor reflections)).
The output gain functions offer the possibility to adjust this level balance, depending on the configuration and use.
According to the room geometry, the actual level balance which needs to be adjusted may differ from the aforementioned reference values. It is, therefore, always necessary for a sound technician to carry through fine adjustments of the output gains when the system is set up.

Input and Output Delays (Delay Button)
After pushing the DELAY button, the first settings you access are for the input delays.
Pushing the button repeatedly will give you access to the output delays.
The units for the delays can be converted from milliseconds (ms) to metres (m) at Util
→
If one of these delay values is not zero, the red LED on the DELAY button lights up. a) Use the Input Delays
Delay lines are speakers which are set up behind one another. The delay times of the speakers’ sound propagation is compensated using delays.
The purpose of delay lines is to ensure that the sound from the speakers near the stage reaches the listeners in the back of the audience simultaneously (preferably) with the sound from the speakers in the rear audience area.
You can separately adjust the delays of up to four input channels, with every channel having a total available delay of 200 ms or 68.6 m. Because a delay of 0.02 ms is already set up in the LSBlock ACCESS High, the available delay time when using this LSBlock is reduced accordingly by this amount. b) Use the Output Delays speakers, for example from flown tops to standing bass speakers, stage edge speakers to the main system, etc. You can separately adjust a total of 4 output channels.
Out 1 and Out 2 share 20 ms or 6.86 m delay time.
Out 3 and Out 4 also share 20 ms or 6.86 m delay time.
These values decrease if there is already a delay set in an LSBlock.
If you select a delay of 5 ms or 1.715 m for Out 1, then there are another 15 ms or
5.145 m available for Out 2. The same also applies for Out 3 and Out 4. The value stated next to ‘Avl =’ indicates how much delay time is still available.

The LSBlock 'Flat' is a distinctive feature. It is intended for special uses such as processing or transmitting line signals, or using third party products or Kling &
Freitag speakers where no LSBlock is available. In this LSBlock, all filters are switched off, and there is also no subsonic filter intended! It is still possible, though, to equalise signals with the help of the PEQs and the EQ 31 band.
When using speakers with the LSBlock 'Flat', the limiter must be set at Out
→ of the speakers. You can find the power ratings of the speakers in the information provided by the speaker manufacturer (no liability for misrepresentation). With the following diagram, you can match the power specifications from the speaker manufacturer with the value for LimReduction that we recommend. We, therefore, recommend initially setting the LimReduction lower than recommended, and then carefully approaching the correct setting for the speaker.
The LSBlock 'Flat' is preset for 500W RMS @ 8
Ω and 2000W Peak @ 8Ω.
Selected values for LimReduction, depending on the power ratings [W] of the speakers:

AmpGain
This is where the CD 44 shows the determined amplifier gain of the power amplifiers connected to the SENSE / RETURN connectors. After switching off the unit the settings always stay at the last plausibly determined value. As soon as a signal that can be analysed by the controller is applied to the Sense connectors, the controller determines the gain of the connected power amplifier. This value helps the controller to automatically adjust the limiter threshold. The controller continually checks this value and re-adjusts the limiter thresholds automatically, for example, when the gain of the power amplifier is changed manually.

If you do not use the connectors ’AMP RETURN / SENSE’, there is imminent danger that the speakers could be destroyed. Exception: When operating the CD
44 with SP speakers, the AMP RETURN / SENSE inputs are not used, since the SP speakers are equipped with their own limiters. See more on this topic in the
chapter SP Speakers on the CD 44 as of page 55.

LimReduction
The limiters have been set during manufacturing so that they provide optimal operating safety and a wide dynamic range when used with adequately sized power amplifiers.
−
If power amplifiers are used that are too small, the limiter threshold can be decreased by up to 20 dB so that the power amplifier does not begin to clip.
−
For events where a reduction of the sound emissions is legally required, you can adjust the limiter so that the maximum permitted sound level is observed.
−
Rental companies can set the limiter lower to protect their speakers from overloads caused by untrained personnel. For example: long-lasting techno events where the speakers can be pushed to their limits.

The current versions of the subwoofer ACCESS B5 and ACCESS B10 have a Speakon connector that is assigned to 1+/1- for both chassis. For these versions, you do not need the following adapter! If you want to connect a 1+/1- assigned ACCESS bass, then connect the ACCESS subwoofer like other 1+/1- assigned K&F subwoofers.
ACCESS B10 with EP -5 connector:
In this example, the B10 is only connected to one channel of the CD 44! A connector is used, though, that supplies 2 channels. When connecting the B10, use a two-core cable with the assignment 1+ and 1-. You should use one of the following adapters at the speaker input of the B10 in order to transmit the signal to both chassis.

When using subwoofers with integrated crossover on the CD 44, set the XO switch on the connecting terminal of the subwoofer to XO ’OFF’.
Important
Switch on the subwoofer’s connecting panel
We do not recommend the passive use of a subwoofer at a top speaker (XO ‘ON’) on the
CD 44.
12.
SP Speakers on the CD 44
The line inputs of the SP speakers are only connected with the desired outputs of the controller (Out 1 through Out 4). Connecting the amplified signal to the connector AMP
RETURN / SENSE of the CD 44 is not possible with an SP speaker. This is not necessary, though, because the SP speaker is equipped with its own limiters guaranteeing the operating safety.
If you do not wish to use the limiter in the CD 44, set up the AmpGain as followed: Out
→
Output 1 through Output 4
→
If you also wish to use the limiter in the CD 44, i.e. for level limiting, then you must set the
AmpGain to +30.0. With this setting, you can select the desired level limit at
Out
→
You can use the SP speakers in two different ways on the CD 44:

Recommendations for Configuration
13.1 Operating several Speakers per CD 44 Channel
The maximum number of speakers which can be operated at one time using the CD 44
Controller is limited by the minimum output impedance of the power amplifiers.
Make sure the power amplifier has sufficient headroom.
No further adjustments need to be made to the CD 44 Controller when operating with several speakers connected to a single controller. There is no need to adjust the limiters.
They receive the necessary information via the voltage applied (not via the current).
SP speakers: Up to 50 SP speakers can be connected to one channel.
Important
13.2 The correct Level Balance between Bass and Top Speakers
When setting up the system it is very important to ensure that the volume levels of the tops and bass systems are correctly balanced.
The sound level of arrayed bass speakers increases by max. +6dB when doubling the number of speakers (+3dB efficiency plus 3dB by doubling the power amplifier level). The loudness of the tops increases in a different manner because of the directivity.
A bass speaker which is on the floor can be a few decibels louder than a flown bass system because of the floor reflections.
With the CD 44, you can adjust this level balance to meet the requirements of different configurations and applications.
In order to intuitively set the output gain, it is important to remember that the output gain must always be set at 0 dB for the following speaker combinations
(applies to systems placed on the floor):
−
1 small top and a subwoofer with one chassis
−
1 large top and a subwoofer with two chassis
−
ACCESS top T5 or T9 with 2 x ACCESS B5 or 2 x ACCESS B10
CA 106 and CA 1001 are regarded as small tops. All other tops with available LSBlock, except the ACCESS, are considered to be large top.
The following tables show how this relationship is to be set for the particular configurations. In doing so, it also considers if the systems are flown or placed on the floor.
The data given apply to bass systems placed on the floor and are valid on the condition that all systems are driven by identical power amplifiers with the signals set at the same level (we recommend maximum level)).
When using power amplifiers with different gain characteristics it can become necessary to adjust the balance between top and bass system using the output gain control of the CD 44.
Depending upon room acoustics and geometry the correct settings may well differ in practice from that given here. For this reason the sound engineer should always carry out a fine adjustment.

Instructions for AES / EBU Data Transmission
14.1 General Instructions
The interface AES / EBU offers the possibility to transmit two digital audio channels via a balanced cable. The sampling rate of the audio signal may be 32 kHz, 44.1 kHz, 48 kHz,
88.2 kHz, 96 kHz or 192 kHz with a resolution of max. 24 bits. The Kling & Freitag CD 44
System Controller supports any type of sampling rates ranging from 44.1 kHz to 192 kHz with a resolution of max. 24 bits.
When using the AES / EBU input, in addition to the system delay of 0.5 ms, a further delay arises from the sample rate converter: With a sample rate of 44.1 kHz = approx. 2.4 ms.
With a sample rate 48 kHz = approx. 2.2 ms. With a sample rate 88.2 kHz = approx. 1.5 ms.
With a sample rate 96 kHz = approx. 1.4 ms.
As the handling of digital audio signals in practice differs from that of analogue signals, you should observe the following suggestions in order to ensure dependable operations:
−
The maximum cable length between two devices is 150 m.
−
Use shielded ‘Twisted Pair’ cables with an impedance of 110 • (80 - 150 • are tolerable). They are available at specialty stores and are called ‘AES/EBU Cables’.
−
Do not mix any cables with different impedance within one transmission line.
−
Do not use any ‘classical’ XLR audio cables!
−
The cable may not be bent too much or pulled over sharp edges. Please observe the permissible minimal bending radius which is provided by your cable’s manufacturer.
−
Ensure the soundness of the connectors.
−
If the AES/EBU signal is to be distributed over several lines, then a special line splitter is necessary.
If no special 110 • AES/EBU cable is available, then data cables for lighting technology (DMX data cable with an impedance of 120 •) can be used.
14.2 Transmissions over long Distances
If transmission distances exceeding 150 m need to be covered, it is necessary to use a repeater.
The interface AES / EBU is the European Broadcasting Union’s implementation of the
Standards AES3 defined by the Audio-Engineering Society.
Further information is available at these organisations: www.aes.org und www.ebu.ch

Wiring
Hardware K&F CD 44 Digital System Controller
Make sure that all units are switched off and all controls are turned down before connecting your system.
−
Only use high-quality speaker cables, (i.e. from KLING & FREITAG).
−
Adapters for connections between the Speakon connecting panel of the CD 44 and EP-5
/ XLR-connectors, as well as for special uses must be professionally constructed.
−
For analogue connections from the mixing console to the power amplifier inputs, please use shielded microphone cable with two conductors. For digital signal transmission you will need shielded twisted pair cables.
−
Please pay attention to the respective pin diagrams in this manual!
−
Avoid ground loops.
−
Make sure that the +/- polarity of the speakers at the amplifier is correct. When simultaneously 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.
−
Ensure that the connected speaker channels are working in phase (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 cannot be located.
−
The cables should have a sufficient wire gauge. A minimum wire gauge can be easily calculated with the following formula:

Operating the Controller
−
Make sure to observe the installation instructions and safety notes shown in the loudspeaker manuals and in the user's manual for loudspeakers and assembly equipment.
−
Switch off all equipment and turn down all level controls on the mixing console and the power amplifiers.
−
Wire the speaker systems according to the instructions in this manual.
−
Now switch on the mixing console first, followed by the CD 44 Controller and, at last, 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.
−
Successively turn up the individual power amplifier channels and send a signal with low volume to the system. Check to see if the desired signals are applied to the intended speakers and make sure there is no interference. Make sure everything works properly, i.e. if the signals come from the correct speaker paths (high signals from the tweeters, bass signals from the bass speaker). The SIGNAL-LEDs of the CD 44 Controller light up if there is an output signal greater than -45 dB. Your system is ready for use.
−
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 signal interruptions caused by protection circuits or damages to the speakers, turn the level controls of the power amplifier to the maximum position, if possible. Only turn up the signal level at the mixing console or on the controller far enough so that the power amplifiers are not overloaded; or
Out1 through Out4

−
When turning off the system, turn down the input controls for the power amplifiers first, then switch off the power amplifiers and all other appliances.
