Description

Sound-effect amplifier special for sound and dance hall

The utility model relates to a kind of stereophonic effect amplifier of dancing hall special use.

The stereo set of using in all kinds of dancing halls at present all is the form that multichannel is imported the output of two sound channels, though many high-grade stereo sets, the output of two sound channels about also having only.So perfect stereophonic effect just can not be given full play of.

The purpose of this utility model is the acoustics that a kind of stereophonic effect of strengthening in the music of design is experienced the people to enrich more surround sound effect true to nature.

Scheme of the present utility model is as follows: in order to strengthen the stereophonic effect of music, device is designed to the form that multichannel input, multichannel output and the output of two sound channels combine.Each input sound channel of multichannel input has two input interfaces; One of them is that pickup is amplified interface after preposition amplification, sneaks into the electrophonic musical instrument interface.Two input signals mix after tone circuit is input to the inverting input that mixes amplifying stage, export to final-stage power amplifier again.The pick-up interface of each sound channel is the special purpose interface of jazz's drum, and interface is fixed to all kinds of jazz's drums as in army's drum, bass drum, port drum and the small cymbals with microphone or pick-up.The electrophonic musical instrument interface respectively inserts the plug of No. one electronic musical instrument, as electricity doubly department, electric guitar, electronic organ etc.The sound equipment that output connect of each sound channel can be put into each corner in dance hall.Simultaneously, and the output of two sound channels that connect be two-way combined power amplifying stage, promptly general stereo set is had.

The power of each sound channel is exported each corner that the sound equipment that is connect is put into the dance hall, and two output audio amplifiers that play proportionality action are placed on the band both sides.Like this, make the people in dance hall can not only hear the whole structure of band, also can enjoy the solo effect of every musical instrument.When music sounds, make people feel that every musical instrument in the band all plays at diverse location, be that jazz drum, army's drum, bass in the jazz band amplifies the sounds that all interlock in each corner in dance hall such as drum, upright small cymbals, especially after melody enters climax, the performance that port is bulging fast, continuous, more can make the people feel that the sound of drum is in dance hall different corners non-stop running, give the fresh and new impression that rouses oneself, really make the people feel the effect in " stereophonic " border, reach real stereo.

The drawings and Examples explanation:

Fig. 1, Fig. 2 are the utility model embodiment, and Fig. 1 is global design figure, and Fig. 2 is the circuit pack details drawing.

Present embodiment is established the input of eight sound channels altogether, the output of the output of eight sound channels and two balanced sound channels.Eight pickups that comprise the Eight-channel input are amplified interface PUIN1 ...
