Definitions
- the invention relates to a method for configuring a Public address system with at least one loudspeaker and an audio signal supplying the speaker box, an amplifier comprising DSP in the audio signal path. Further The invention relates to a configurable public address system as well as a loudspeaker and an amplifier, which in of such a configurable public address system are.
- the constantly changing structure of the sound system has Consequence that optimal acoustic results are not always achieved become.
- the invention has for its object a method for Configure a PA system to specify which one Optimization of the system with any combination of amplifiers and loudspeaker box. Furthermore, a corresponding Public address system, a loudspeaker box and a correspondingly configurable amplifiers can be created.
- data is stored in the loudspeaker box, which a certain, desired signal processing in Affect amplifiers.
- the loudspeaker gives these data the signal processing in the amplifier before that leads to the best possible sound result. So the data can as a "regulation for optimized amplifier operation" be understood.
- the data are in one both amplifier hardware / software non-specific as well in a loudspeaker-unspecific data format.
- the data in a by universal Rules which are independent of the specific one used Amplifiers and the specific loudspeaker used predetermined form are stored in the speaker box and be transmitted.
- data format the whole of these rules or conventions.
- the data is transferred from the speaker box to the amplifier transferred and interpreted there.
- the interpretation data contain the required information about the digital signal processing section used, especially DSP, and therefore enable the Calculation or generation of the settings for the digital Signal processing section required specific Parameter data.
- the interpretation data specify which signal processing steps from the specific Case DSP implemented in the amplifier are executable, for which signal processing steps other components in the amplifier and on the other hand, which signal processing steps of the specific amplifier hardware / software not be supported.
- the interpretation data So put the exact knowledge of what is used in the amplifier DSP ahead and contain the hardware-specific Information with which the transmitted from the loudspeaker box Data in DSP-specific setting or parameter data can be implemented.
- the invention between the speakers data and the amplifier hardware / software a new level of translation or interpretation introduced, which allows loudspeakers and amplifiers in a self-configuring public address system Operate and mix across types and generations to be able to.
- the presentation of the data in the loudspeaker box should be next to the required generality as low as possible Computational effort when interpreting the data and Support the shortest possible data transfer times. This requires optimization of the form of presentation of the data (i.e. the data format) especially with regard to avoidance of redundancy in the records.
- At least some of the data records are preferably each one assigned functional element known in amplifier technology, the respective functional element by means of a functional element identification data field unique in the data set is identifiable.
- the functional element identification data field facilitates the interpretation of the received Data.
- the term functional element is too broad understand and can be both a hardware component (either hybrid or integrated in the DSP) as well as a software module in the denote digital signal processing section of the amplifier.
- a first data record of a filter sequence For example, a first data record of a filter sequence, a second record a peak limiter (so-called peak limiter) to avoid a short-term Speaker overload, a third record of a diaphragm deflection limiter to limit the membrane deflection, a fourth record of a continuous power limiter (sometimes also known as a thermal limiter) to limit the Continuous output power of the amplifier, a fifth record a relative time lag of the audio signal other outputs of the amplifier and a sixth record the total gain and phase of that from the amplifier output audio signal must be assigned (the numbering does not imply any particular sequence of records in the data format).
- peak limiter peak limiter
- a diaphragm deflection limiter to limit the membrane deflection
- a fourth record of a continuous power limiter sometimes also known as a thermal limiter
- the first record (which is assigned to a filter sequence is) can furthermore have a filter identification data field, which is used to identify different filter types serves.
- a filter identification data field which is used to identify different filter types serves.
- a data record has a data record identification data field.
- This data field is, for example, with a continuous Number assignable and enables the Differentiation also of such data sets, the identical functional elements assigned (i.e. identical functional element identification data fields exhibit). This will achieved that several versions for one and the same component of a data record can be created.
- the provision of a record identification data field in the record takes into account the fact that it is for a speaker possibly not just a valid setting of the amplifier, especially the DSP. Because for different Operating modes and installation options etc. of the loudspeaker different optimized parameter data result for the amplifier. That is why the data format offers in the way indicated the possibility of different Specify versions of records which (after data interpretation) to different settings of the amplifier or DSP. The setting options can then selected on the amplifier or on the respective amplifier channel become.
- the interpretation data is also required for the data conversion, which are held in the amplifier.
- This Data relate exclusively to information relating to the Amplifiers used hardware and possibly software (Firmware) and are therefore also before downloading the data from the loudspeaker box is available in the amplifier.
- the interpretation data are independent of the straight one connected loudspeaker, i.e. it is not necessary, the interpretation data at the launch of update new speakers.
- An update of the However, interpretation data can be used when converting the Amplifier (e.g. replacement of the DSP or a new programming of the DSP) become necessary. It can therefore be beneficial be the interpretation data in a programmable Keep memory, which is written via an interface can be.
- the interpretation data can be freely selected (i.e. device-specific) data format held in the amplifier become.
- the interpretation data preferably contain data which are assigned to the channel structure of the amplifier, for example Information about the number and structure of each Channels; Data on the sampling frequency used in the DSP; an indication of the gain factor of a power amplifier stage the amplifier; an indication of the Short-term output voltage, e.g. as the sine mean, one Power amplifier stage of the amplifier; and information about the internal delay times of an analog-to-digital converter or a digital-to-analog converter in the audio signal path of the amplifier in front of and behind the DSP.
- An advantageous measure of the method according to the invention is that before converting the data obtained into Parameter data for the digital signal processing section it is checked whether this is the requested signal processing provides at all.
- a simple form of one Verification is, for example, checking whether sufficient amplifier channels available in the amplifier and whether enough output power from the amplifier is available stands.
- it can be checked, for example, whether the digital signal processing section, in particular DSP or the DSP software (firmware), requested signal processing steps supported. If the review leads to the result that for the digital signal processing section a requested signal processing cannot be carried out the user can do this by issuing a Warning notice will be communicated.
- a warning can be issued in an advantageous manner if, when implementing the data, the occurrence of a Error is detected.
- the amplifier works without corresponding data from the loudspeaker in a preset standard operating mode. If a connected speaker data transmitted, which is only a part of the digital signal processing section, especially DSP Signal processing functions are preferred provided that the other signal processing functions Define according to the default.
- this is a data storage includes in which the desired signal processing data in an amplifier in a predetermined, data format independent of the type of the loudspeaker are. These can then in the manner already explained by an amplifier that has the data interpretation functionality described above exhibits, evaluated and used.
- An essential aspect of the amplifier according to the invention consists in the fact that it comprises an interpretation unit, which is based on the interpretation data from the Loudspeaker received data calculated the parameter data to configure the digital signal processing section, especially suitable and necessary DSP.

- the analog-digital and digital-to-analog converter 2.1, 2.3 are optional because the amplifier 1 is also supplied with a digital input signal can also be a reinforcement in digital Signal range can take place. Further amplifier components can also be used in the audio signal processing circuit 2 be included.
- the amplifier 1 further comprises a configuration circuit 3.
- the configuration circuit 3 is a Data storage 4 assigned.
- the configuration circuit 3 is available via a data transmission medium (e.g. data bus) 5 the audio signal processing circuit 2 in data connection and is capable of 6 data via a data transmission means read out from the data memory 4.
- a storage medium 9 is assigned to a loudspeaker box 8.
- the loudspeaker box 8 is connected via a cable connection 10 connected to the amplifier 1, the cable connection 10 from a speaker cable 11 and a data transmission link 12 exists. It can be seen from the direction of the arrow that corresponding audio signals for operating the loudspeaker box 8 are transmitted from amplifier 1 to loudspeaker box 8.
- the Data transmission path 12 is provided with double arrows, which indicates that bidirectional data exchange between the configuration circuit 3 and the storage medium 9 possible is.
- speaker wire 11 can also be used for data transmission. In this case there is no separate data transmission link 12.
- FIG. 2 shows a further example of a public address system, in which the same or functionally identical parts as in 1 are designated by the same reference numerals.

Data can be retrieved at the same time or individually for each speaker box 8, 8 '.
- the data interpretation which is more closely based on FIGS. 4 and 5 is based on additional information about the hardware and / or software structure in the amplifier, which is available for configuration circuit 3.
- This additional Information is in the form of so-called interpretation data stored in the data memory 4. Access to this data is done as required in the course of data interpretation. For example, it is conceivable that a loudspeaker box 8, 8 'a certain setting of a component (e.g. a specific digital filter). In this case first by calling up the corresponding interpretation data determined whether this filter in the DSP 2.2, 2.2 ' or maybe as a separate component elsewhere in the Signal path of the audio signal processing circuit 2, 2 'or is present at all.
- a component e.g. a specific digital filter
- the interpretation data stored in the data memory 4 concern only information about hardware and / or Software in the amplifier, i.e. via the DSP 2.2, 2.2 'if necessary the other in the audio signal processing circuit 2, 2 'contained functional elements. Because this information is independent of different speaker types, it remains valid for future generations of loudspeakers. It is therefore always possible to calculate parameter values on the basis of the respective loudspeaker boxes 8, 8 ' transferred data taking into account the interpretation data be performed.
- step S5 the calculated parameter values are over the Data transmission means 5 of the audio signal processing circuit 2, 2 'fed. This becomes corresponding in step S6 of the received parameter values configured. If there is of several channels is the calculation of the parameter values performed for each of the channels and a corresponding one Setting of the multi-channel DSP 2.2 'made.

- filter type an identification field
- the following table 2 shows a possible assignment of the field variable filter type to a description of the corresponding filter type using characteristic data.
- the identification fields for the signal processing elements and for the filter types must before the technical realization the public address system according to the invention by convention (for example according to tables 1 and 2) and should then no longer be used for compatibility reasons be changed. By using the identification fields becomes the interpretation of that from the speakers 8, 8 'data obtained considerably simplified.

- The are just those records whose first data field is a Identification field ("Element ID"), i.e. in which in Fig. 4 example shown all data records with the exception the record for the speaker name and the record for the variant definition.
- the four variants differ according to the variant definition by alternatively using the data records with the Element numbers 1 or 2 or 3 or 4 included, whereas the records with item numbers 5 and 6 in all Variants are included.
- the records with the element numbers 1 to 4 describe four different filter sequence versions.
- the first two filter sequence versions (records with element numbers 1 and 2) only contain a filter. In both cases it is the same Filter (filter type 4), the only difference in the Filter setting values for the frequency response fg (50 or 150) find is.
- the specified identification fields, variable and field types as well as the structure of the individual data records and elements can be defined and structured in many other ways become. It is crucial that through the selected data format on the one hand a description as comprehensive as possible all possible signal processing functions in one Amplifier is supported, and that on the other hand short transmission times and a simple one with little computation feasible interpretation of the in this format by the Data delivered to loudspeakers is possible. Furthermore the file format should be like the one shown here Example, be "open", so that future developments in the amplifier area through a "downward compatible" Format expansion can be taken into account.
- the interpretation data held in the data memory 4 of the amplifier 1 contain specific technical information or Numerical values regarding the structure or the specifications the amplifier hardware including firmware, which are necessary are from the data received from the speakers to calculate an "executable" parameter set. In contrast you need for the data supplied by the loudspeaker box not according to a special, generally applicable format convention be structured.
