Affected by the epidemic, people's outdoor leisure activities have been greatly reduced, and through the 4K home private theater to enhance the entertainment experience, relaxation is more and more liked and accepted by everyone.
Compared with public cinemas, private home theaters not only provide a quiet and relaxing environment, but also do not lose the sense of atmosphere of the theater, but also meet the diverse viewing needs of family members.
So, how do you build a home theater? What are the precautions for choosing audio-visual equipment? Let's take a look!
First, 4K home theater program selection
The home theater system includes parts such as signal source input, display, sound system, wiring engineering and space layout. At present, there are three main options for home theater construction solutions on the market:
Rental party simple matching plan: connect intelligent projection screen/projection equipment through laptop/mobile phone to achieve large-screen movie viewing effect.
Living room theater transformation plan: while retaining the function of the living room, the living room will be transformed into a video and audio space;
Professional-grade av room program: with sufficient space and budget, build a separate audio-visual room in the home;
For most people, setting up a private theater is still quite difficult. After all, whether it is the addition of projection, audio and other audio and video equipment, or embedded wiring projects, the cost required is not a small amount, it is recommended that you choose according to the indoor space environment and budget.
Second, what are the precautions for purchasing audio-visual equipment and cables?
1. 4K input device
The 4K input device is the signal source of the 4K home theater. At present, there are more and more choices of input devices that support 4K content, such as: Xiaomi box, Tencent Aurora box and Sony Blu-ray disc player, etc., these flagship devices are configured to support the playback of 4K quality content.
Trivia 1: At present, the main ways to obtain 4K content in China are: TV 4K live broadcast, 4K UHD Blu-ray disc, 4K hard disk copy film source and network online 4K video source.
2. 4K display device
A 4K ultra-clear display device is the focus of the home theater system, after all, 4K +HDR+3D+surround sound + ultra-high refresh rate and other technologies directly affect the audiovisual effects of epic war movies, superheroes and other movies!
Nowadays, with the continuous advancement of 4K audio-visual technology, the market penetration rate of 4K audio-visual terminals continues to increase, and more and more flagship-level configurations of 4K TVs, 4K intelligent projection and other equipment have begun to be delegated to the thousand-yuan market, which allows users to have more choices.
Of course, for the sake of cost performance, we can also choose to buy second-hand 4K display devices at low prices from formal channels.
3. 4K ultra-clear HDMI cable
In order to completely present the 4K film source, in addition to the audio and video equipment to reach the 4K level, it is also very important to choose the right HDMI video line. At present, the common HDMI video lines on the market are mainly version 1.4, version 2.0 and version 2.1.
Among them, the theoretical bandwidth of HDMI version 2.0 is 18 Gbps, which supports 4K@60Hz lossless transmission; the theoretical bandwidth of HDMI version 2.1 is 48 Gbps, which supports lossless video with resolutions and refresh rates such as 4K/120Hz, 8K/60Hz, and 10K, which is a new video output scheme for the future.
4. 4K power amplifier and sound system
For movie enthusiasts, the visual shock is important, but the auditory experience cannot be ignored. The audio sound reinforcement equipment that usually constitutes a home theater sound system mainly includes power amplifiers, speakers (left and right channels/surround, etc.) and subwoofers.
Little knowledge 2: The amplifier can be understood as the "horsepower" device that drives the speaker, which amplifies, mixes, splits and fronts the signal output by the sound source, so that it generates a large enough current to drive the speaker to work.
Little knowledge 3: The terminal equipment of the sound system is generally divided into active speakers and passive speakers.
Among them, the amplifier is the processing center of the entire home theater, and the signal source must be processed and sent to different back-end output devices, such as: TV, projection, speaker, etc. That is to say, the quality of a power amplifier directly affects the sound and painting expression of the entire home theater system. So, what aspects do you need to pay attention to when buying a 4K home theater power amplifier?
In terms of configuration and functions, in addition to the HDMI2.0 standard interface and 4K ultra-clear video decoding capabilities, home theater power amplifiers and audio equipment also need to support cinema-level 5.1+7.1 channel combinations, Dolby Atmos, Hi-Res HD audio certification, etc. In addition, we should also pay attention to the power output of the amplifier and the speaker to be reasonably matched!
