Chapter 926 The main focus is on professionalism
“The current equipment is different from the original testing machine,” Liu Xiaowen apologized with some embarrassment: “Now they are all customized by factories in Guangdong Province and then shipped here. Not only the quality of the equipment has improved, but the shipping costs are also very expensive.”
“Then it’s factory-based, and the cost has to be lower.” Zhou Zhi said with a smile: “Find a factory. OEM cooperation is enough, as long as the materials used are good and the profit is enough, it will be almost the same."
Liu Xiaowen stomped her feet in embarrassment: "That's not the case. Now we all use plating for wiring. The silver wire, the board and cover of the speaker, and the paint have all been upgraded."
"Okay, sister Liu, don't worry, can't I just follow your orders?"< br>
"That's pretty much it." Liu Xiaowen smiled and brought the coffee and put it in front of them. Then she realized it and was 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: "Excuse me... can you renovate the karaoke room?" "
"Yes, our Wuse Audio Equipment Company is specialized in this and is also the pioneer of AC solutions for karaoke halls. You can trust us to pour a cup of coffee for the guests." Zhou Zhi. Seeing that Liu Xiaowen didn't look like a professional and technical person, she immediately pretended to be a technician.
The customer who came was a fat man, wearing a floral T-shirt and holding a big wallet: "What...AC...solution?"
"Come, come, please sit down." Zhou Zhi invited Fatty 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 main design purpose of the AV amplifier's sound playback method is 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 have many sound amplification methods. Designed for high fidelity, it pays attention to amplifying the signal from the signal source. It is mainly used to enjoy music, vocals, etc., and pursue the true effect of the sound."
"From the perspective of the number of playback channels, AV amplifiers have Four to nine channels, push multiple speakers to form a surround sound field, For example, the 5.1 channel of Dolby AC-3 is the first and classic karaoke solution we designed. "
"The Hi-Fi amplifier has two channels when playing sound. channel, that is, amplifying the signals of the left and right channels, and pushing the left and right Set up speakers to form a stereo sound field. For example, in the place we are now, the music we hear is produced by the Hi-Fi amplifier."
"Please tell me about 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 carry out sound field design, power design, and choose the appropriate one according to the area of the karaoke hall. Two-stage amplification equipment and 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 affected. Limited by the echo interference of the venue, the power amplifier will be limited by the price. ”
“Our Five Color Audio Equipment Company will never let customers spend a penny more. Every design plan is absolute. Tailor-made. "
"It's so complicated..." Fatty became confused: "I thought I could just buy a set of equipment and put it on..."
"Brother, you are right. It is indeed possible to just buy a set of equipment and put it on display." Zhou Zhi smiled: "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 the karaoke hall is a relatively specialized one. As a 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 have a few songs, right?” “But they are not professionals, right?” Singers need to use equipment to modify their voices. ”
< br>“This is similar to professional concert hall design. From equipment to venue, every aspect is meticulous, so we call it a ‘solution’. The final sound field effect can definitely surpass the ordinary. There are several karaoke parlors in your area.”
“If you already have one locally. If you go to a karaoke room, 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 a drawing, can you draw a rough sketch of what the place will look like? I will explain it while drawing, 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, but there are a few pillars in the middle, almost in these positions."
“Oh , Brother, this place is really well chosen." Zhou Zhi took the pen and said, "Where is the entrance? Where is the window? Oh, this place is just right. Look, let's do this. This pillar is used here to separate a DJ sound control room , here is arranged as a stage, here is a large projection screen, here is a small screen for the singers to watch, and there is also a..."
"There are also teahouses and bars, roughly this circle, requiring boxes and The partitions can be adjusted additionally."
“The next thing is the key point. We are going to use Dolby 5.1 surround sound, and the low, mid and high sound speakers are independently matched. Sister Xiaowen, do you have a red pen? I will mark the sound field layout for my brother. …”
Liu Xiaowen took a red pen with a smile and looked like I'm 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, and the sound field is such a fan shape. These are...these It's a high note, the high note is like this...Brother, do you see anything?"
"I can't understand your overlapping paintings..."
"Oh brother, you are so right, you hit the key point in just one sentence! Zhou Zhi looked admiring the other person and said: "It's overlap! You see, the circle around the teahouse basically has the overlap of three sound fields, high, medium and low, and they come from different directions. This is called surround sound. ! ”
“Look now, are every sound area clear? We still say that every penny must be implemented clearly and 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 things to say here! I have looked for two or three companies before, not to mention drawing drawings, but no one can explain it clearly, just asking me to pile up money!"
"Of course, Because I haven’t seen your architectural drawings yet, so what I drew is It's just a first draft." Zhou Zhi smiled and said: "Building a sound field is just like building a house. We must have a solid grasp of the parameters of each piece of equipment before we dare to make such a request."
"Brother, look at this." Zhou Finally, she 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."
"The things I went to your house are a bit expensive. Yeah? ”
"Is it expensive?" Zhou Zhi looked as if he was frightened by the fat man's argument.
