A: Yes, you can send money directly to us via bank transfer, Alipay or WeChat transfer. Currently, cash on delivery is not supported.

Q: Why do you want to divide the pre-level and the post-level?
A: Popularly speaking: the pre-level voice, the post-level output. After the disc player (or storage device) reads the disc, the data is output to the pre-stage, and the pre-stage decodes the sound signal to the subsequent stage, and the latter stage amplifies the sound signal to the speaker to make a sound.
The domestically popular Japanese power amplifier is an all-in-one machine, that is, the function of decoding and signal amplification is integrated, and the Japanese power amplifier cannot meet the power demand of the speaker because of the well-known power virtual standard problem. Therefore, the research will start with a larger volume to store the pure copper ring of the real material, and more and more heat sinks to ensure the pure output of the stable output of the machine.
It is to fill the short board and maximize the overall effect of the system.


Q: Under what circumstances do you need to add a post-level?
A: If you use the sound system, you feel that the sound effect is not tolerant. When you are in a big dynamic, you will miss the door. The punch will not come to the meat, the sound will be too clear, and there will be a sense of powerlessness. This is likely to show you Need to add a later level.
Most of the combined amplifiers have the problem of insufficient power. You need to add the post-level to meet the needs of the whole system. If you are not sure, please recommend to buy back the audition effect, leave the satisfaction and leave us with dissatisfaction.


Q: Your post-level is only 200-300W. The professional machines sold by others can't move 500-1000W.
Still too cheap, is it better?
A: I don't understand it. In KTV and conference rooms, most of them are professional amplifiers and professional speakers. If this kind of machine is equipped with household speakers, it is very likely that the speakers will be burned when there is great dynamics, and the 'professional equipment' will be More serious distortion, making people feel noisy and unbearable. The L&W sound is specially designed for the private audio-visual room. There is a big difference between the design of the post-stage and the professional amp. The penny is the same as the market. The sky will not fall, and if it is, it is also a trap. Please be sure to look for the strength of the big factory. (Note: The term 'professional' in the audio industry specifically refers to equipment specially configured for KTV and conference rooms, and does not mean a higher level of meaning)


Q: My speaker is marked with a required power of 180W. Your rear output is 250W. Will it burn my speaker?
A: When you receive the device, it is recommended that you test each channel and then use it for normal use. From the tight, cold, hard, and thick sounds, it becomes more mellow, smooth, delicate, and mature. The more heavy-duty, high-powered products, the more pre-heated the longer the time to mature. After connecting our equipment to your system, there is an immediate effect, and I believe that even more surprises are still coming.
(The downtime is a measure to quickly stabilize the equipment. Some components such as transistors, integrated circuits, and capacitors are new when the electrical parameters are unstable. After a period of use, they can be gradually stabilized, and the compliance gradually becomes better. Good state)
