Abstract
The invention discloses a professional power amplifier with a DSP (digital signal processor) digital speaker processor. The professional power amplifier comprises a case, a front panel and a rear seal plate and is characterized in that a power steady-pressure plate, a power transformer, a power amplifier and a fan are arranged in the case, a DSP digital speaker processor, a signal input module, a computer interface module and a loudspeaker output module are fixed on the inner side of the rear seal plate, and the computer interface module is provided with an RS485 or USB (universal serial bus) port; the rear seal plate is provided with a power input socket, a power insurance tube socket and a radiating hole thereon; the front panel is provided with a DSP liquid crystal displayer, a volume control knobs, function selection keys and a power switch thereon. Compared with the prior art, the professional power amplifier has the advantages that installation space can be effectively reduced, funds for purchasing singular peripheral audio equipment are effectively saved, troublesome installation and debugging are omitted, convenience in management is achieved, the professional power amplifier can be connected with a computer, and the power amplifier can be better managed.
Description
Technical field
The present invention relates to apparatus for processing audio, relate in particular to a kind of professional power amplifier with DSP digital sound box processor.
Background technology
In sound system design, stage specialty public address, in Installation and Debugging and other application, everybody is more or less for some reason (as: due to the sound field defect of building, is utilized equalizer to compensate in public address environment, reached the object of sound frequency equilibrium; In public address environment, often need many group audio amplifiers to carry out public address, just having there is the time difference in the sound-reducing of this compensation audio amplifier and main sound box, causes the asynchronous of sound, by the calculating to sound, time delay can address this problem, so adopted delayer; It when microphone pickup, can not be all the audio signal of standard, signal gets too small or excessively big city affect public address effect, so just adopted compressor) and adopted electronic frequency divider, electronic equalizing device, audio frequency compressor, audio delay device, these peripheral equipments become the assistant who improves public address quality, and they become one in public address the visual plant configuring according to need.See that to a certain extent these equipment have been the indispensable parts of sound reinforcement system.Owing to having added these equipment, system is closely linked, the connection of these equipment needs a lot of wire rods and connector, the index of some equipment does not reach requirement, will cause overall technology index to decline, also can cause debugging problem (simulation is there is no memory function, is misoperation once there be people, will change overall effect).
Summary of the invention
The present invention is in order to solve above-mentioned deficiency, and a kind of professional power amplifier with DSP digital sound box processor is provided.
Above-mentioned purpose of the present invention realizes by following technical scheme: a kind of professional power amplifier with DSP digital sound box processor, comprise cabinet, front panel and rear shrouding, it is characterized in that: in described cabinet, be provided with power supply voltage stabilizing plate, power transformer, power amplifier and fan, described rear shrouding inner side is fixed with DSP digital sound box processor, signal input module, computer interfaceJi Suanjijiekou module and loudspeaker output module, and described computer interfaceJi Suanjijiekou module is provided with RS485 or USB port; Described rear shrouding is provided with power input socket, power safety base and louvre; Described front panel is provided with DSP liquid crystal display, volume control knob, function selection key and mains switch.
Described cabinet both sides are provided with handle.
The present invention's advantage is compared with prior art:
1, it effectively reduces installing space, has also effectively saved the fund of buying these single periphery stereo set equipment, has removed loaded down with trivial details installation and debugging from, and Comparison of Management is convenient, also can be connected with computer, manages better power amplifier.
2, use the DSP digital processing chip of vast capacity, its set electron frequency divider, electronic equalizing device, audio frequency compressor, audio delay device technology, module is incorporated in amplifier and is harmonious with the young pipe power amplifier of the metal cap movement of inventor's independent research, doing easily Active crossover, delay process, balanced instruction, audio frequency presses limit etc. allow the correction that is improved of complicated audio curve environment, allow the sound of sound system more resistance to listen purer, thereby improve the project quality of sound equipment.
3, connect control by RS485 or USB port, the software on PC can be controlled multiple machines, accomplishes that man-machine interface is integrated.
4, the outward appearance of product fashion, front panel and handle are autonomous from wound Design of Dies.
