"The current equipment is different from the original testing machine," Liu Xiaowen added a little embarrassedly: "Now they are all customized by factories in Guangdong Province and then shipped here. Not to mention the quality of the equipment has gone up, and the freight is very expensive.

of."

"That is to realize factoryization, and the cost must be low." Zhou Zhi said with a smile: "Just find a factory to cooperate with OEM. As long as the materials used are not bad and the profit is enough, it will be almost the same."

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

"Okay, okay, sister Liu, don't worry, I'll just take your word for it, okay?"

"That's pretty much it." Liu Xiaowen smiled and brought the coffee and put it in front of them. Then she realized, a little embarrassed: "What do you mean you can get a letter according to my words! You are too bullying!"

While the two were chatting and laughing, someone poked his head at the door and said, "Excuse me... can we renovate the karaoke hall?"

"Yes, our Wuse Audio Equipment Company specializes in this, and we are also the pioneers of ac solutions for karaoke halls. You can trust us. Sister Liu pours a cup of coffee for the guests." Zhou Zhi looked at Liu Xiaowen as not being professional.

As for the technical ones, they directly pretended to be technicians.

The customer who came was a fat man, wearing a floral T-shirt and carrying a large wallet: "What...ac...solution?"

"Come on, come on, please take a seat." Zhou Zhi invited the fat man to sit in front of another small coffee table: "Let me introduce it to you. Currently, 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 amplifier is mainly designed to create a sound field, emphasizing the directionality of the sound and simulating the atmosphere of the listening environment, such as cinemas, halls, churches, stadiums, studios, etc."

"Hi-fi amplifiers are mostly designed for high fidelity in terms of sound amplification methods. They focus on amplifying the signal from the signal source. They are mainly used to enjoy music, human voices, etc., and pursue the true effect of sound."

"From the perspective of the number of playback channels, AV amplifiers have four to nine channels, which drive multiple speakers to form a surround sound field. For example, the 5.1 channel of Dolby ac-3 is the first one we designed and it is also a classic

The perfect karaoke solution.”

"The hi-fi amplifier has two channels when playing sound, that is, it amplifies the signals of the left and right channels, and drives the left and right sets of speakers to form a stereo sound field, such as the place we are now.

, the music you hear is produced by the hi-fi amplifier.”

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

"Ah, do you still need architectural drawings?"

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

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

"Our Five Color Audio Equipment Company will never let customers spend a penny more. Every design plan is absolutely tailor-made."

"It's so complicated..." Fatty started to get confused: "I thought I could just buy a set of equipment and put it up..."

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

And excellent service is not enough.”

"Because a karaoke hall is a relatively professional place, consumers' experience 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 entertain themselves with a few songs, right?

"

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

"This is similar to professional concert hall design. From equipment to venue, everything is particular, so we call it a 'solution'. The final sound field effect can definitely surpass the average karaoke performance."

The OK restaurant is several blocks away.”

"If you already have a karaoke hall in your local area, you can inquire and ask them if they are looking for professionals and if they have considered professional sound field design. By the way, even if you don't bring drawings, you can roughly draw them.

What does the place look like? This way I can draw and explain it, and your feelings should be more direct."

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

The fat man recalled it and drew a rough pattern: "Actually, my place is not too complicated. It is square and square, with a few pillars in the middle, almost at these positions."

"Oh, brother, this place is really well chosen." Zhou Zhi took the pen and said: "Where is the entrance? Here, right? Where is the window? Oh, here... this place is just right. Look, brother, we

In this way, this pillar is used to separate a DJ sound control room, 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 teahouses and bars, which are roughly in this circle. If you need private rooms and partitions, you can adjust them separately."

"The next thing is the key point. We are going to use Dolby 5.1 surround sound, with independent speakers for low, mid and high frequencies. 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 she was watching how you perform.

"Brother, look, our subwoofer should be placed here. This is the sound field range of the speaker; here is the midrange, the sound field is such a fan shape, these are...these are the treble, and the treble is

Like this... brother, do you see anything?"

"I can't understand the many layers of your paintings..."

"Oh brother, you are so right, you hit the key point in one sentence!" Zhou Zhi looked as if he admired the other party to the point of admiration: "It's just overlap! You see, the circle around the teahouse basically has the three tones of high, high and low.

The overlapping of fields and coming from different directions is called surround sound!"

"If you look at it now, are every sound range clear? We still say the same thing, every penny must be implemented, and you must see it clearly."

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

"Well, young man, you are really good. It turns out there are so many ideas here! I have looked for two or three companies before, let alone drawing drawings, and none of them can explain clearly. They just want me to 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 just like building a house. We know the parameters of each piece of equipment.

You have to have a solid grasp of it before you dare to give me such a vote."

"Brother, look at this." Zhou Zhi took out the manual that Liu Xiaowen had planned to hide before: "For your large venue of 300 square meters, we need such a set of equipment."

"Are the things I bought at your house a bit expensive?"

"Is it expensive?" Zhou Zhi looked as if he was frightened by the fat man's argument.
