Description
Technical field
The utility model relates to a kind of multi-functional hall digital camera function audio system switch.
Background technology
At present, the audio system of general multifunctional hall private theatrical view, amusement, performance is divided into following major part: source of sound part, tuning part, peripheral part, public address part; The source of sound part comprises equipment such as video disc player, deck, Mike again; The tuning part mainly comprises this professional audio controller of sound console; Peripheral part comprises equipment such as balanced device, chronotron, frequency divider, effect device; Public address partly comprises power amplifier and audio amplifier, and audio amplifier is divided into main sound box, auxiliary audio amplifier and foldback monitor speaker three parts again, and wherein main sound box can comprise the subwoofer audio amplifier; General digital camera audio system generally includes: source of sound part, digital decoder and power amplifier part, audio amplifier part.The partly existing normal DVD player that adopts of source of sound, the multiple tracks sound signal that output was made through early stage; Digital decoder and power amplifier part generally exist split and two kinds of forms of one, and power amplifier has generally comprised the tuber function of audio frequency periphery again; Audio amplifier partly comprises main sound box, surround speaker, center-channel speaker, subwoofer audio amplifier four parts.Generally use voice band line special-purpose insert row in parallel or carry out the voice band line grafting temporarily for the switching of above-mentioned professional audio public address and digital camera audio decoding technique by operating personnel, the system that finishes is switched, these modes generally exist connection, complicated operation, go wrong easily in the operating process, and to operating personnel's skill level shortcoming such as have relatively high expectations.Because the deficiency of above existence, the function of the digital camera of the multi-functional hall of present major part that makes really do not realize, generally use original public address system to see a film, and make people be without access to real digital camera spot effect true to nature.
Summary of the invention
The purpose of this utility model provide a profit can make between the output of sound console and digital decoder freely switch, simple to operation, convenient, safe multi-functional hall digital camera function audio system switch.
The purpose of this utility model is achieved in that it is made up of switching device shifter and the tuning knob of passage be located on the panel, described switching device shifter is provided with two input ends and an output terminal, two input end is communicated with the audio output of sound console and the audio output of digital decoder respectively, an one input end is electrically connected with the tuning knob of passage, outputs to peripheral equipment and power amplifier and audio amplifier again by the tuning knob of passage then.
Described switching device shifter is made up of 5 binary channels change-over switches of parallel connection, and they are respectively: keynote passage change-over switch, consonant and around 1 passage change-over switch, consonant and around 2 passage change-over switches, monitoring and mid-passage change-over switch, auxiliary and back mid-passage change-over switch.
The technical progress that the utility model is obtained is: the utility model adopts the multiple tracks change-over switch, make more convenient to operate, quick, change original switching mode and the higher drawback of unexpected problem occurred, solved the attenuation problem of signal allocation, make the signal allocation mode possess alternative, stereo commentaries on classics monophone is provided with more convenient and practical; Simultaneously, also make the conferencing function, multimedia teaching function, performance function, Kara OK function etc. of the existing multi-functional hall obtain extension, make it to have possessed the function of digital camera, changed the deficiency of using public address system to show a film in the past, made the digital camera function of the multi-functional hall be able to real realization.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is the front view of the utility model panel.
Fig. 2 is the rear view of the utility model panel.
Fig. 3 is that circuit of the present utility model connects switching principle figure.
Fig. 4 is a user mode synoptic diagram of the present utility model.
Among Fig. 1-4,1. be keynote passage change-over switch, 2. be consonant with around 1 passage change-over switch, 3. be consonant with around 2 passage change-over switches, 4. be the tuning knob of passage, the 5. auxiliary and mid-passage change-over switch in back is 6. for monitoring and mid-passage change-over switch, 7. be multi-functional hall audio input port, 8. being the digital camera audio input port, 9. switching the back output port, 10. is digital decoder, 11. be the source of sound part, 12. be sound console, 13. is switch, 14. is peripheral equipment, 15. be power amplifying device, 16. is audio amplifier; Wherein 1-1,1-2 are first passage, the second channel of keynote passage change-over switch; 2-1,2-2 are consonant and first passage, second channel around 1 passage change-over switch; 3-1,3-2 are consonant and first passage, second channel around 2 passage change-over switches; 6-1,6-2 are first passage, the second channel of monitoring with mid-passage change-over switch; 5-1,5-2 are first passage, second channel auxiliary and the mid-passage change-over switch in back.
Embodiment
Shown in Fig. 1-4, the utility model is made up of switching device shifter and the tuning knob 4 of passage be located on the panel, described switching device shifter is provided with two input ends and an output terminal, two input end is communicated with the audio output of sound console 12 and the audio output of digital decoder 10 respectively, an one input end is electrically connected with the tuning knob of passage, outputs to peripheral equipment 14 and power amplifying device 15 and audio amplifier 16 again by the tuning knob of passage then.Switching device shifter is made up of 5 binary channels change-over switches of parallel connection, and they are respectively: keynote passage change-over switch 1, consonant and around 1 passage change-over switch 2, consonant and around 2 passage change-over switches 3, monitoring and mid-passage change-over switch 6, auxiliary and back mid-passage change-over switch 5; 5 binary channels change-over switches have two passages again respectively, i.e. the first passage 1-1 of keynote passage change-over switch, second channel 1-2; Consonant with around first passage 2-1, the second channel 2-2 of 1 passage change-over switch; Consonant with around first passage 3-1, the second channel 3-2 of 2 passage change-over switches; Monitor first passage 6-1, second channel 6-2 with mid-passage change-over switch; Assist first passage 5-1, second channel 5-2 with the mid-passage change-over switch in back.
Its principle of work is as follows: the signal that the utility model can send source of sound part 11 switches by 5 two channel switch in parallel between 10 outputs of sound console 12 and digital decoder, when switch 13 switches to sound console 12 controls one end, continue to use under the situation that original audio system functions such as meeting, amusement, performance are not affected basically like this; When switching to digital decoder 10 these ends, can fully satisfy multichannel requirement, realize the digital camera function of the multi-functional hall.
