How Do I Choose the Best Home Subwoofer Amplifier?

Home theater audio refers to the sound that is specifically configured for movie playback. As the name implies, its style should be close to that of the theater, so the minimum configuration should be 5.1, decoding Dolby, and DTS to achieve surround sound.

Home theater audio

AV speaker speakers

Mainly used for home hi-fi

People often say that the playback system mainly includes three major components, namely audio and video players, AV amplifiers,

Clean contacts every six months

Soon after the metal is exposed to the air, the surface will oxidize. Even if the surface of the signal cable plug is gold-plated and in close contact with the body plug, over time, there will still be a certain degree of oxidation leading to poor contact, so it must be cleaned at most every six months. As long as the contacts are coated with cotton and alcohol, the contacts will be restored to the best contact after the heavy work, and the sound will be clear and transparent.

Try to avoid stacking machines

As far as possible, the most important CD source and sound reinforcement should be placed independently, because overlapping placement will cause resonance and affect the machine. When the speaker is playing music, the vibration of the air causes the equipment to follow the vibration, and the two machines will harmonize with each other when they are stacked, making the subtle information in the music blurred, and disturbing the transmission of various frequency bands, causing a sound pollution For example, if one of them is a CD player, the continuous rotation of the motor during the playback of the disc intensifies the amplitude of the harmonic vibration, and the impact is even greater. Therefore, the equipment should be placed on a stable rack independently.

Less interference, more beautiful sound

Household appliances and computers in the room should avoid sharing a set of power with the audio, and even if they are put together, they should get power from elsewhere. Secondly, tangling the wires will also cause the wires to absorb noise from each other and damage the sound quality. Regardless of equipment or connection lines, they should be kept free from interference from other electrical appliances or power lines.

Speaker placement

The placement of the speakers is an important part of the use of the audio. If not placed properly, the playback effect will be greatly reduced. How to find the best placement in the room is quite difficult. In addition to constantly listening to the effects of different placements, you can also ask relevant experts to give guidance.

Dim environment helps listening

Turning off the lights and listening to music is a habitual problem, but it has nothing to do with playback, but in a dark environment, the ears will be particularly sensitive, and it will reduce visual obstacles, reorganize the sound picture and the sense of position of the instrument It will feel particularly clear and clear, the atmosphere is far better than when it is turned on, and some other dim lights can be used to create a listening atmosphere.

Sound absorption should be appropriate

In the general home environment, furniture and debris are already good

China can independently develop and manufacture a full set of theater audio (

Myth 1: Good products equal good results.

Good quality equals good results. This is the understanding of most users, but for home theater, this is not applicable. Good effects require not only good products, but also good installation and debugging.

Myth 2: Ignore the impact of the environment on the effect.

A set of high-quality home theater equipment is placed in an inappropriate environment, and the effect is not as good as a set of ordinary quality home theater equipment in a suitable ring, so the overall environmental layout and location are decisive for the effect of the home theater effect.

Myth 3: All products of superstition brand are good.

It is undeniable that many brand-name products do have their own unique advantages and technical advantages. However, each brand has certain technical limitations. That is to say, some products of some brand-name products are very good, but some products are average. The superior products are the key to building a home theater.

Misunderstanding 4: Do not pay attention to installation and commissioning.

Good products, good environmental design, do nt forget that good installation and commissioning are equally important. Place the right equipment in the right place, and debug the appropriate effect to some extent according to the environment and user s preferences, main purposes Say it's more important than buying a good product.
