1. Speaker: many people think that they should be loud disco, much more on speakers, subwoofer, fact, what things have a degree, it backfired. First of all to ensure sufficient power, subwoofer must be selected 18 inch products, because the driver was bigger, deeper bass elementary, high-power work breaks have trouser leg shaking feeling. The second is enough to guarantee a low frequency, his power ratio should be the entire system is largest, speaker to be selected to reflect the fast, powerful, it is best to use the 12-inch products. Then there is the high frequency of that paragraph, its proportion is not very large, as long as you can hear him clearly, power over Congress makes a person feel very noisy, short time will feel upset, prompted a recent visitor to leave. II. display: this issue should separate the subject for discussion. At the disco, just two display modes, one for decentralized, most are the speakers hanging around in the floor; the second is a centralized, speaker and became a circle, the Horn to hanging above the center of the dance floor, also known as the nacelle. In view of the construction difficult, this approach is less. There are many places will also become extremely low sound child circle around the dance floor, this will reduce the bass power, and you will receive significant wave crest and the trough, bass sounds odd, ambiguous, and some local bass is very small, listen to the voices of flat flat. The best solution, the bass box as close as possible to the dance floor in a row display, such as difficulty can be shaped, but firmly cannot be success circle or two box to drop. Then bass speaker back metres a hard wall brickwork, height to exceed the speaker, so you will find bass power seemed large double and clear and strong. A place for beautiful speaker will be lifting rings hanging above the dance floor, is very beautiful but not practical, after all, we are using sound to playback music, and not for decoration. Simple and effective way: the speaker is divided into four point lifting, the wings and the opposite sides of the stage, the speaker into four groups, so that it can also be adjusted. 3. equipment: 1 speaker: said earlier speaker choice, again: a subwoofer must be selected 18 inch products, hanging box above the dance floor as selected double-12 products, taking into account, theatrical performances in the wings with 15-inch 3-n products. 2 a mixer: this is the entire system is the most relevant links point to be sloppy, disco in the channel are less, but still no marshalling what functionality, you must choose one of the import manufacturers of products, prices were high. But be aware that many brands to * production, quality and quality also sent a lot, choose carefully! 3 surrounding: the room for a little, you can go select high cost performance products, the compressor is required, unless you want to forget it is for the Horn. Essential effects, import and production of price difference * much better quality then, try to choose Import. 4 power amplifier: * production technology has completely cross the border and quality can, should, as far as possible, the selection, unless the money more bite the hand or hard to charge and facade. 4. tuning: the crucial 1 PA, many people think that a more advanced, in stereo loudspeaker is selected the stereo mode, but it is not, in the disco when selected stereo loudspeaker will be having a lot of drawbacks. By disco speaker placed, simply cannot tell which is the left channel, which is the right channel, with stereo sound can only be a mess, no good results. Mono is out, it will lose a lot of music details. I tuned in disco time selected is mixed Mono, two-channel signal transmission into the mixer, single of the button to play the Middle, so that the two input signals at the same time into the mixer left and right channels, four groups of speakers receive the same signal that spread out equally sound. 2 balance adjustment, especially in the bass part, not the larger and more shocking low frequency! instead some environment to attenuation and low frequency band to improve the clarity of the music. Slightly elevated medium frequency band, enabling music feel slightly forward so that strong feeling strong baritone. High-frequency adjustment is important and appropriate decay, high-pitched sounds clear but not harsh, necessary full-frequency boxes of the treble takes a few to try it, will have unexpected results. 3 press the regulation, this is critical, the most simple way: add compression for output to a minimum, the power amplifier volume all the way up, adjust the sound mixer output to 0 DB, adjust the compressor output to listen to the live sound until the speaker full-load work, feeling the scene volume is sufficient, if you can, live output limiter, all amplifier volume knob down 2 DB. If you feel the volume is not enough, you should, where appropriate, additional speakers. 4MIC adjustments, this is also critical, a slight upgrade if a mixer so that sounded strong, powerful, slightly mellow sound effects, best sound with actuator for more penetrating. Let the MIC sound slightly larger than the music to be heard clearly, not too noisy five, this time we talk about how to perform in both disco and dance. 1 to two completely different system. (This is a money didn't place flowers boss plus ** engineer products that are not discussed). 2 said before, to the entire system of Riga 3 frequency box, which is specifically designed to perform preparations. If you have used many model speaker experience friends will have experience, 2 frequency box expand the voice and 3 frequency of simply FABI, inexperienced friends don't have to try it out, because the result is the same. 3: 2 in the main system of Riga, the Ministry the equalizer to concatenation. Will one (assuming equilibrium 1) bypass, with another (assuming equilibrium 2) to adjust the balance curve diqu, fine balanced 2 bypass after, and then balanced balanced 1 adjustment performance curve. Note that it should switch off the loudspeaker on the other side of the stage, as the case off the subwoofer, this step is critical! performed with 4: 1, when you use the equilibrium and the gateway box off, balanced 2 bypass; dancing with balanced 2, box full open, balanced 1 bypass. Action 5: according to this method of adjustment, such as singing, and no treble, screech, and other illnesses disappeared, and the work became very easily.
