Abstract
Provided is a digital audio matrix which comprises a master control device, a switchboard, a computer, CD players, and loudspeakers. The switchboard and the CD players are connected with the master control device. The computer is connected with the switchboard. The loudspeakers are connected with the CD players. Using digital audio processing and having a local audio signal self-checking function, the digital audio matrix has a good effect on subarea volume debugging and audio signal intensity determination, saves a lot of device debugging time, and provides effective basis for fault determination timely. The access manner of the digital audio matrix is control signal RJ45 access, so the digital audio matrix has a large extending space and can be accessed where network is present. And the network is not required to be reconstructed. The built-in short circuit input interface and short circuit output interface of the digital audio matrix may achieve multiple expansion functions such as an infrared sensing probe and an electronic switch or the like.
Description
Technical field
The utility model relates to audio frequency apparatus, is specially a kind of digital audio matrix.
Background technology
At present, used audio frequency and video integrated system mainly carries out transfer of data with analog signal in the Public Address system, common power amplifier output volume is unified, but zones of different is inconsistent for the sound pressure level size requirement, and function is comparatively single and the analog signal time-delay is bigger, can't satisfy growing multiaspect and broadcast demand to type.
The utility model content
The technical problem that the utility model solves is to provide a kind of digital audio matrix, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of digital audio matrix comprises master control set, switch, computer, CD player and loud speaker, and described switch and CD player are connected on the described master control set, and described computer is connected on the described switch, and described loud speaker is connected on the described CD player.
In the utility model, also be provided with network interface, circuit output interface, circuit input interface, short circuit input type selector switch, short circuit input interface, short circuit output interface and power input interface on the described master control set.
These novel occasions such as school, factory, commerce, meeting that are widely used in; Different occasion demand sound pressure level sizes are all handled by digital audio processing system, satisfy on-the-spot volume demand, reach the integrated target of multinomial function.
Beneficial effect
The utility model adopts digital audio processing, carries the local audio signal self-checking function, to each subregion volume debugging and judge that the audio signal power plays good effect, saves a large amount of commissioning device times, judges for fault timely and effective foundation is provided; Originally novel is that control signal RJ45 inserts for access way, and wider space is very big, as long as there is the place of network just can insert, does not need to set up again network; The short circuit input, the output interface that carry can be realized more expanded functions, as: infrared induction probe, electronic switch etc.
Description of drawings
Fig. 1 is a kind of digital audio matrix schematic diagram.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
A kind of digital audio matrix, comprise master control set 1, switch 2, computer 3, CD player 4 and loud speaker 5, described switch 2 and CD player 4 are connected on the described master control set 1, and described computer 3 is connected on the described switch 2, and described loud speaker 5 is connected on the described CD player 4.
In the utility model, also be provided with network interface 6, circuit output interface 7, circuit input interface 8, short circuit input type selector switch 9, short circuit input interface 10, short circuit output interface 11 and power input interface 12 on the described master control set 1.
In the utility model, can broadcast subregion to the sound pressure level size requirement according to difference by arranging, the different big small volumes of output, thus it is undistorted to reach the audio signal high-fidelity; Thereby avoided common power amplifier output volume to fix, can't satisfy different broadcasting subregions to the inconsistent drawback of sound pressure level demand; And then satisfy various occasions to the demand of broadcast singal.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model; the technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall in claimed the utility model scope, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
