What we have to figure out is that the sound effect is described by characteristics. It can't be simply used or not. The KTV sound has a big difference with the stage sound, home audio, and fever audio: a KTV sound in a designated area. To get the biggest recognition of the target consumer group, it is necessary to form a consumption habit that conforms to the regional culture and conforms to a certain consumer group. KTV audio designers and investors need to make rational decisions, and the so-called successful experience cannot be completely copied.
Due to regional differences and the characteristics of consumer groups, the requirements for sound effects are also different. Some require the effect of HIGH, and the effect is quite shocking; others require the perfect combination of vocals and music. But no matter what, the design of the KTV sound effect is the basis for all the effects.
KTV sound effect design includes audio equipment configuration, private room decoration, private room furniture selection, audio equipment installation, audio equipment parameter settings and other aspects. Here we mainly discuss the configuration of the KTV audio equipment.
There are many kinds of KTV audio equipment, and there are many configuration and combination schemes. It is a technical and complicated project to select the best combination among many equipments. KTV audio equipment configuration pays attention to eight words: the singer is comfortable, the listener is comfortable, or say, singing comfortably and listening comfortably. This 8-word mantra is simple to say, and it is impossible to achieve it without any effort.
The selection of KTV room speakers is divided into main speakers and auxiliary speakers. The main evaluation of the room speakers is that the performance of the vocals should be outstanding, and the sound phase should be right. (Listen to see if the vocals can be sent out, and some speakers will feel The vocals are behind the box. The music frequency is wide and dynamic enough. The choice of private room speakers should be decided according to the consumption pattern of the target consumer group. The karaoke consumer consumption concept in big cities is relatively mature, and the entertainment venues are classified finely. Basically, K and HI can be considered or less. Compatible, look at the investor's market positioning, pure K's main consideration of vocal expressiveness, 8" woofer speaker vocal performance is best, 10" woofer speaker music will be much better, vocals are slightly worse.
The choice of microphones in KTV audio configuration is very important. Early engineers like to use stage professional microphones such as SHURE. Until recently, they realized the professional attributes of karaoke microphones. Karaoke microphones require long-term resistance to the net, anti-wear, and switch. Durable, tough to the lead, this is the most basic requirement. The most important thing is that the karaoke microphone must not be so easy to give back the whistle (flying cockroach), and it is necessary to optimize and enhance the vocal, and attenuate the low frequency and vocal excess. Ultra-high frequency makes the middle and high frequency of the human voice more prominent, so-called easy to sound.
DC Cable is the Cable used for the products with DC (direct current) output like all AC/DC adapters including laptop Adapter , desktop adapter, wall plug adapter, Printer Adapter, and Linear Adapter and so on. The one end of dc cord is 2 or 3 open wires to connect with adapters or chargers, the other end of DC Power Cable is different dc jack, standard dc jacks for laptop adapter are 5.5*2.5, 5.5*2.1, 5.5*1.7, 4.8*1.7, 4.0*1.7, 3.5*1.35, , 3.0*1.0, 2.5*0.7, 2.0*0.6, 4.0*1.35, 6.3*3.0, 5.5*3.0 with pin, 7.4*5.0 with pin, 6.5*4.4 with pin, 4.5*3.0 with pin, 4 pin, 4 hole, 5 hole oval, 3 pin, 3 hole, etc, and standard dc jacks for tablet are 2.5*0.7, 3.0*1.0, 2.0*0.6, micro usb, and mini usb, etc.
Except dc jack, three main specifications are OD of cable, length of cable and materials specifications inside of cable. OD means outer diameter, it is normally 3.5mm for wall plug adapter, 4.0mm, 4.5mm, 5.0mm, 5.5mm for big power laptop adapter and other ac/dc adapter. Length is normally 1.2m, 1.5m, and 1.8m, also 2m, 3m, 5m are customized produce. The materials inside are pure copper, CCA ( copper and Aluminum) and CCS (copper and steel), pure copper is the best, CCA is second, CCS is the lowest, yidashun never uses CCS; And the thickness for the materials inside are normally 0.15mm2, 0.19mm2, 0.2mm2, 0.33mm2, 0.41mm2, 0.5mm2, 0.75mm2, 1mm2, 1.25mm2, 1.5mm2, 2mm2 and so on. Normally we use 0.15mm2 and 0.2mm2 for below 30W adapter, 0.41mm2 and 0.5mm2 for below 90W adapter, and 0.75mm2 and more thickness for above 90W adapter.
