For a perfect home theater renovation, the biggest home theater design challenge is to plan the entire audio-visual room into a professional and comfortable experience space. Acoustics and aesthetics must be perfectly combined, especially with all kinds of audio and video equipment. Based on the above premise, we propose a custom private theater renovation project, which is to create a suitable experience space according to different spatial proportions, different series of audio combined with acoustic decoration specifications.
Let's take a look at some of the places in the private theater that need attention.
1. Setting the correct placement of the speaker is the key to good sound reproduction in the room. If you can follow the introduction of the speaker placement in the previous sections of this chapter, it will take a few hours to try to find the proper placement position for the speaker, which will not only achieve good sound reproduction, but also increase the number of sound reproduction effects. Listening to the experience and being able to hear the difference in sound quality. All room acoustics processing is based on the proper placement of the speakers. If the speakers are placed in the wrong position, all the rest of the effort is futile. Welcome to Qiangqiang Home Theater Decoration Network
2. The length, width and height of the room should have a good proportion. Although in most cases, the room is already built. The ratio of length, width and height has already been fixed. However, if there is a chance to select a room for the listening room, it is best to refer to the ratio of the length, width and height of the room listed in section 3.1 of this chapter in order to avoid standing waves as much as possible. Because this is also a selection condition for the audio equipment to obtain good sound reproduction.
3. Try to avoid bare parallel surfaces. If there are bright, face-to-face parallel surfaces without any acoustic treatment in the room, you will hear multiple breaths. Simply apply a sound absorbing material to one of the surfaces, such as sound absorbing foam, ASC's sound absorbing material that eliminates multiple echoes, a small piece of tapestry or carpet-like sound absorbing material, especially ASC's Tube. Special sound absorbing equipment such as Trap can absorb bass at the same time, allowing the reflected sound waves of the side wall to spread and eliminate multiple echoes.
4. Absorb or scatter the reflection of the side wall and the ground. Try to lay a carpet on the smooth ground before the speaker and the speaker. Place some sound-absorbing or scattering sound waves on the side wall between the speaker and the listening position. There are reflective surfaces such as bare walls and windows nearby. American ASC's Tower Trap sound tubes, various sound absorbing foams, and RPG diffuser screens can be effectively used to eliminate side wall reflections. The bookshelves placed on the side of the side wall also spread the sound waves well.
5. Keeping the reflector away from the speaker cabinet, power amplifiers, furniture, and other objects placed near the speakers can degrade the sound and sound fields. Therefore, you have to try to move these objects away. For example, move to the back of the speaker. If they cannot be removed, they should be covered with sound absorbing materials.
6. It is not always possible to get a room with a very high height and a slope, but it would be best if you could choose a room with a higher height and a slope to make a listening room. Such a room not only changes the indoor resonance mode between the floor and the ceiling, but also reduces the early reflection at the listening position, making the bass more round and round, and the space is more spacious. The speaker should be placed at the lower end of the ceiling.
7. Balance the absorption of treble and bass. Most rooms tend to absorb too much of the treble, while the absorption of the bass is not enough. Carpets, curtains, and soft furniture are used in conjunction with some materials that absorb bass to keep the reverberation time constant throughout the entire frequency band. Overweight and slow bass is caused by the imbalance of reverberation.
8. Move the listening position to achieve the best balance of the bass. The standing wave will produce some constant high sound pressure and low sound pressure zone indoors. Try moving the listening position for the best balance. Avoid sitting in the ground near the back wall, because the bass here will be too heavy.

9. Using irregular planes or grotesque objects to disturb the retired graphics Deliberately placing some furniture or objects will help to disturb the standing waves formed in the room. Placing large pieces of furniture behind the listening position will spread the reflections of the back walls behind the listener.
SFP (Small Form-factor Pluggable) can be simply understood as an upgraded version of GBIC. GBIC (abbreviation for Gigabit Interface Converter) is an interface device that converts gigabit electrical signals into optical signals. GBIC is designed to be hot-swappable. GBIC is an interchangeable product that meets international standards. Gigabit switches designed with GBIC interfaces have a large market share due to flexible interchangeability.
GBIC modules are divided into two categories: one is the GBIC module used by ordinary cascade to realize the ordinary connection with other switches; the other is the stack dedicated GBIC module to realize the redundant connection with other switches.
GBIC was basically replaced by SFP for the following reasons:
SFP (Small Form-factor Pluggables) can be simply understood as an upgraded version of GBIC.
SFP module (the volume is reduced by half compared to the GBIC module, and the number of ports can be more than doubled on the same panel.
Because the SFP module is basically the same as GBIC in function, it is also called Mini-GBIC (Mini-GBIC) by some switch manufacturers.
The SFP module further compresses the size and power consumption by putting CDR and electric dispersion compensation outside the module. Used in optical communication applications in telecommunications and data communications. SFP connects the motherboard and optical fiber or UTP cable of network equipment such as switches, routers and other equipment. SFP is an industrial specification supported by some fiber optic component providers.
SFP supports SONET, Gigabit Ethernet, Fiber Channel and some other communication standards. This standard is extended to SFP+, which can support 10.0 Gbit/s transmission rate, including 8 gigabit Fibre Channel and 10GbE. Introduced the optical fiber and copper core version of the SFP+ module version. Compared with the Xenpak, X2 or XFP version of the module, the SFP+ module keeps part of the circuit on the main board instead of the module.
