Riding the wind of rebirth

Chapter 925

"The current equipment is different from the original testing machine," Liu Xiaowen said a little embarrassedly: "Now it is customized by the factory in Guangdong Province, and then shipped over. Not to mention the higher grade of equipment, the shipping fee is very expensive. of."

"That is to achieve factoryization, and the cost must be low." Zhou Zhi said with a smile: "It's fine to find a factory to cooperate with OEM. As long as the materials are not bad and the profits are enough, it will be made with almost the same quality."

Liu Xiaowen stomped her feet in embarrassment: "That's not the case. Now the silver-plated wires we use for wiring, as well as the boards and covering materials of the speakers, and the paint water have all been upgraded."

"Okay, okay, sister Liu, don't worry, I'll just follow what you said, okay?"

"That's about the same." Liu Xiaowen brought the coffee over with a smile and put it in front of them, and then realized that she was a little embarrassed: "What do you mean by letter according to my words! You are too bullying!"

While the two were chatting and laughing, someone poked his head at the door: "Excuse me...can you pack up and repair the karaoke hall here?"

"That's right. Our five-color audio equipment company is specialized in this. We are also the pioneer of AC solutions for karaoke halls. You can trust us. Sister Liu pours a cup of coffee for the guests." Zhou Zhi didn't seem to understand Liu Xiaowen professionally. Those who are technical, directly pretend to be technicians.

The customer who came was a fat man, wearing a floral t-shirt and carrying a big wallet: "What... AC... solution?"

"Come here, please take a seat." Zhou Zhi invited Fatty to sit in front of another small coffee table: "Let me introduce to you, the power amplifiers we use are mainly divided into two types, AV power amplifiers and Hi-Fi power amplifiers."

"The sound playback method of the AV power amplifier is mainly designed to create a sound field, emphasizing the sense of direction of the sound, and simulating the atmosphere of the listening environment, such as cinemas, halls, churches, stadiums, studios, etc."

"Hi-Fi power amplifiers are mostly designed with high fidelity in the way of sound reproduction, and pay attention to amplifying the signal from the signal source. They are mainly used to appreciate music, human voice, etc., and pursue the real effect of sound."

"From the perspective of the number of playback channels, the AV power amplifier has four to nine channels to drive multiple speakers to form a surround sound field. For example, the 3 channel of Dolby AC-5.1 is the first one we designed, and it is also a classic. The best karaoke solution."

"The Hi-Fi power amplifier has two channels when playing sound, that is, amplifies the signals of the left and right channels, and drives the left and right speakers to form a stereo sound field, such as the place we are in now. , The music you hear is from the Hi-Fi amplifier.”

"Excuse me, for the karaoke hall we are going to renovate, have you brought the architectural drawings?"

"Ah, do you still need architectural drawings?"

"Uh... yes, because in line with the principle of being responsible for the customer, we need to design the sound field and power design, choose the appropriate two-stage amplification equipment, and arrange the appropriate speaker equipment according to the area of ​​the karaoke hall."

"Theoretically, the higher the power of the equipment, the better the effect, but there is a premise that the speakers will be subject to the echo interference of the venue, and the power amplifier will be subject to the price."

"Our five-color audio equipment company will never let customers spend more money, and every design plan is absolutely tailor-made."

"It's so complicated..." The fat man became confused: "I thought it would be enough to buy a set of equipment and go back and put it on..."

"Brother, you are right. It is indeed possible to buy a set of equipment and put it back home." Zhou Zhi said with a smile: "But to become an excellent place that embodies professionalism, highlights strength, and is not afraid of competition, it only depends on luxurious decoration. And excellent service is not enough.”

"Because the karaoke hall is a relatively professional place, the experience of consumers here is different from other places. Even if they go to discuss business or drink, as long as they choose to go there, they will inevitably have to socialize a few songs, right? "

"But they are not professional singers, so they need to use equipment to modify their voices."

"This is similar to the design of a professional concert hall. Everything from the equipment to the venue is exquisite, so we call it the 'solution'. The final sound field effect can definitely throw out the general Karaoke The OK Hall is several streets away."

"If you already have a karaoke hall in your local area, you can inquire about it and ask them if they are looking for professionals and have they considered professional sound field design. By the way, even if you don't bring a blueprint, you can roughly draw it What does the place look like? In this way, I will explain while drawing, and your feelings should be more direct."

After speaking, she winked at Liu Xiaowen, who immediately handed over the pen and paper.

The fat man recalled it for a while, and drew a rough pattern: "Actually, my place is not too complicated. It is square and straight, but there are a few pillars in the middle, which are almost in these positions."

"Oh, that brother chose this place really well." Zhou Zhi took over the pen and said, "Where is the entrance? Here? Where is the window? Oh here... this place is just right. Look, brother, let's In this way, here is a DJ sound control room separated by this pillar, which is arranged as a stage, here is a large projection screen, here is a small screen for singers to watch, and there is also a..."

"There are also tea seats and bar counters, which are roughly in this circle. Boxes and partitions can be adjusted additionally."

"The next thing is the key point. We will use Dolby 5.1 surround sound, and the low, medium and high pitch speakers are matched independently. Sister Xiaowen, do you have a red pen? Let me mark the sound field layout for my brother..."

Liu Xiaowen brought a red pen with a smile, as if I was watching you perform.

"Brother, look, our subwoofer should be placed here, this is the sound field range of the speaker; here is the midrange, and the sound field is such a fan-shaped, these are all... These are the treble, and the treble is Like this...brother, do you see anything?"

"You draw so many layers, I can't understand it..."

"My brother, you are so right, you hit the key point in one sentence!" Zhou Zhi looked admiring the other party and said, "It's overlapping! Look, the circle around the teahouse basically got the three tones of high, middle and low." Field overlap, but also from different directions, this is called surround sound!"

"If you look at it now, is every sound range clear? We still have the same sentence, every penny must be put into practice, and it must be clearly seen by you."

"You see, in each sound zone, the width and depth of the range of high, middle and bass are different. How to match them together can produce the best effect. Do you understand now?"

"Well, young man, you are really nice, so there are so many talks here! I have looked for two or three companies before, let alone drawing blueprints, and none of them can explain clearly, just know to let me pile up money!"

"Of course, because I haven't seen your architectural drawings yet, what I drew is just a first draft." Zhou Zhi said with a smile: "Building a sound field is the same as repairing a house. We have the parameters of each piece of equipment You have to have a solid grasp before you dare to make such a report for brother."

"Brother, look at this." Zhou Zhi took out the manual that Liu Xiaowen was going to hide before: "Your big place of [-] square meters, we have to use such a set of equipment."

"Is it a bit expensive for me to go to your house?"

"Is it expensive?" Zhou Zhi looked shocked by the fat man's argument.
