Definitions
- the invention relates to a method for operating a sound system with at least one loudspeaker box and with at least one amplifier, the via a preferably detachable cable connection is connected to the speaker box.
- the invention is therefore based on the object Method of operating a mobile or fixed Public address system to indicate that despite different Combinations of amplifiers and speakers always to an optimized system leads without complex measures being taken have to.
- the amplifier in a first process step data supplied by the loudspeaker box about acoustic and / or electrical parameters the loudspeaker box by querying the loudspeaker box receives and in a second process step considering the amplifier the data / parameters automatically before operation and / or during operation with the connected one Speaker is configured.
- the Invention is therefore based on the principle that -je after connected loudspeaker - an independent one Configuration is done, that is, by automatic parameterization the properties of the sound system are preferred in electrical as well as in electroacoustic Area optimized in such a way that the best possible Results can be achieved.
- Under "amplifier” is a device in the above sense, that not only enables reinforcement, but by means of signal processing electronics can influence the transmission behavior.
- the configuration is optimized in terms of Transmission behavior, in particular in terms of frequency response and phase response.
- the speakers data supplied by the amplifier evaluated with regard to an optimized frequency response and then the amplifier through the Means familiar to those skilled in the art on the parameters the speaker box adjusted so that each desired frequency response is achieved.
- the configuration is dependent of itself as the loudspeaker ages changing properties and / or individual properties the speaker box takes place. Therefore in such a case there is a time-dependent Configuration before, that is, it will Connection of the loudspeaker box to the amplifier via the cable connection will transfer data to the Age or on the operating time of the Give information to the loudspeaker box.
- the parameters for example the sound behavior of the loudspeaker can change in the course of aging thus about the configuration of the amplifier Compensation.
- time-dependent For example, parameters Changes in acoustic reproduction properties, the electrical properties and / or the magnetic properties.
- the amplifier is merely by manually entering whether it is a parallel connection or a series connection or around is a mixed circuit, for example the parallel connection of two boxes to which one third box in a row.
- a mixed circuit for example the parallel connection of two boxes to which one third box in a row.
- one such recognition also take place automatically when for example, an impedance test on the amplifier side takes place and data is available at the same time, on the speakers used Clues. Knowing the specifically used Loudspeakers in connection with the impedance then lets the amplifier decide automatically whether there is a parallel or series connection.
- the invention further relates to a device for Operation of a sound system that at least has a loudspeaker box and an amplifier, the via a detachable cable connection and / or a non-wired connection to the loudspeaker is connected, for carrying out the above method is provided that the amplifier has an electrical configuration circuit assigned by the loudspeaker Data about your acoustic and / or electrical parameters preferably by means of the cable connection are fed, the loudspeaker box has a storage unit which Provides data, and being the configuration circuit the sound system taking into account the data / parameters automatically before operation and / or during operation with the connected one Loudspeaker configured.
- the cable connection has a speaker cable and a data cable. Therefore, the low frequency cable for the control the speaker is electrically isolated from the data cable. This doesn't mean two separate ones Cables are to be laid, but it is quite also possible that the electrical conductor of speaker wire and data cables from a common Coat are surrounded. Alternatively, however, can also be provided that the cable connection is a speaker cable over which the data is also transmitted become. Hence, for data transmission uses the same electrical cables which are also used to control the speaker. Preferably in in the last case a time sharing operation was carried out, that is, it is configured at a time if no control data for the speaker be transferred and vice versa. By appropriate Switching devices that are electromechanical or can also be electronic in nature, can this required switching, namely from the operation of the speaker to the sound system Operation to transfer the data or vice versa make.
- the data can be electrical or optical Cable (the latter is called fiber) or transmitted wirelessly.
- wireless Transmission is particularly suitable for infrared, Radio or ultrasound transmission.
- the speaker box has an electrical storage unit which Provides data.
- the storage unit contains information about the characteristics of the loudspeaker, about the type of speaker, about the Serial number of the loudspeaker box, over the operating hours the speaker box, about electrotechnical and / or acoustic parameters of the Loudspeaker and / or via possible service comments and so on, the operator's instructions can give to the operation of the speaker box.
- the above list is not complete, but there can also be further data in the be stored.
- the memory content is speaker-specific Has information that - after Query by the amplifier or by the configuration circuit - cause the Configuration can be done so the amplifier on the connected loudspeaker box is voted.
- the amplifier can preferably designed as a power amplifier his. Additionally or alternatively, it is also possible that an audio processor is assigned to it.
- FIG. 4 illustrates what has been said above a flow chart. Switching on takes place in field 11 of the amplifier 1.
- the field 12 clarifies that from amplifier 1 of the identification unit 5 the loudspeaker 4 a supply voltage is fed.
- the field 13 shows that the Identification unit 5 is in stand-by mode, that is, it is waiting for a communication request through the configuration circuit 3.
- the Field 14 corresponds to the measure that communication takes place, that is, the identification unit 5 the communication request of the Configuration circuit 3 receives. Then be then - according to field 15 - due to the communication request Data from the storage unit 6 for Transfer configuration circuit 3.
- the decision field 16 there is a check whether one or whether several speakers 4 connected to the amplifier 1 are.
- j stands for yes and n for no.
- the invention thus relates to an automatic ongoing parameterization of the parameters of a Public address system, for example with regard to the Transmission behavior of this system.
- Overall is a sequence control for testing and configuration provided certain, the speaker box characterizing data from a non-volatile Storage medium, namely the one mentioned above Storage unit 6, read out and over the Data transmission path 9 of the configuration circuit 3 are supplied.
- the speaker box characterizing data from a non-volatile Storage medium, namely the one mentioned above Storage unit 6, read out and over the Data transmission path 9 of the configuration circuit 3 are supplied.
- the speaker box characterizing data from a non-volatile Storage medium, namely the one mentioned above Storage unit 6, read out and over the Data transmission path 9 of the configuration circuit 3 are supplied.
- there is an adjustment to different Type classes of power amplifier-audio processor combinations and / or loudspeaker combinations with the data exchange mentioned above transfer different records , for example consisting of type and serial number.
- the storage unit 6 a type and / or serial number for Transfer configuration circuit 3, so can of those stored in
