Because the biggest weakness of LCD flat-panel TVs is television sound, it is difficult to listen to loud sounds, and there are still popping sounds. It has been using the earthen cannon 2.0 amplifiers and home-made bookshelf speakers that were not satisfied with elimination from Dad’s house to replace TVs. With a sound speaker.
Absolutely hand-built, shell selection of 18 years ago, Kim Jung-VCD's titanium and iron shell, and later dad think the orange panel is too difficult to see embarrassed, just the subwoofer part of the amplifier tube burned when our young couple to Thailand honeymoon when secretly changed A piece of aluminum panel.
The father's love is like this, probably means something like this. Specially wipe the dust before taking photos.
Recently, this home-built amplifier subwoofer has been partially burned by the amplifier circuit, and the subwoofer sounds the same as the wind.
As a result, when I moved out of the amplifier chassis and tried to take a closer look, I accidentally broke the subwoofer's power switch.
Open the power amplifier chassis and watch it. Dad didn't actually design the heat sink for the operational amplifier tube on the subwoofer power amplifier circuit board with the highest transient power.
This is obviously the design flaw of my dad's wild road power amplifier.
Turning on the sound has always been a matter of wind, and the output crossover designed by Dad has led to no subwoofer for subwoofers without power amplifiers. It is really not useful. Dad's recent purchase of full-size SLRs has recently been addicted to bird photography. At the time it was last month (April) on the 14th and 22nd, it was Mangatai's annual heavyweight singing program 2017 "Singer" program finals and the "singer 2017 summit" live broadcast, consider using another Source speaker to emergency.
Generally speaking, the price range of 2300~2500 active speakers is regarded as an entry-level monitor. In fact, there are many models available for selection. The most famous are the Swansea T200C, H5, and then the acoustic engine A5+, BEHRINGER TRUTH B2030A, and acoustic Q5, Eris E5.
HiVi (HiVi) T200C 2.0-channel active monitor speakers Bluetooth speakers audio fashion home speakers 2980 yuan Jingdong direct link This is bad - electricity supplier to buy speakers can not personally audition, but fortunately these are more than a few speakers are more popular, there are more users compared consulting advice and user evaluation.
The comments on the online website “H5 is better than the T200C. The H5 is omnivorous. It is not the monitor box. Please try to please the ear. However, since 2013, many components of the H series have shrunk, but the sound has not changed much and the durability may be compromised. In terms of quality, from the online pictures, the H5 material should be better than the E5, but the H5 tuning is not much more than the E5. However, the H5 with the price of Puri Sonar, Yamaha small white basin, BEHRINGER is much better than the H5."
However, the BEHRINGER TRUTH B2030 has been bought in the study three years ago, and the upgraded version B2031 has not moved. Relatively speaking, the reputation of acoustic engine A5 + active bookshelf listening white piano paint appearance is more eye-catching.
BEHRINGER (behringer) TRUTH B2030A monitor speaker German brand (a pair of equipment) response speed fast resolution dynamic wide sound reproduction without modification 2980 yuan Jingdong direct link Contrast the price of the United States and Asia, the domestic LSR305 that is quite expensive, LSR305 Meiya is 149 US dollars a knife, but also often special 129 knives. BEHRINGER B2030A is also a 149 knife Meyer, Jingdong one to sell 2880RMB, when I bought the audio coupon 2000-500 to 2380 to start. E5, domestic and foreign prices are basically flat.
And BEHRINGER B2030A has a very unsuitable place to use in the living room is its interface, XLR balance port is rarely the output of the organic top box is this specification, the set-top box common Lotus mouth RCA and HDMI and SPDIF.
The picture shows the BEHRINGER XLR interface used in my study. Special custom wire must be used.
Also see the sound engine A5 +, this speaker interface is RCA, basically do not care about using the original set-top box line on the line, acoustic engine A5 + Meiya price is 400 knives, the domestic price is actually even cheaper than Meiya, Jingdong directly cheaper than B2030 four hundred .
Audioengine A5+W Advanced Bookshelf Active Speaker Gao Guangbai 2499 yuan In addition to the “What Hi-Fi?†five-star recommended by the world-famous audio field evaluation institution, it also won the annual awards issued by major professional audio websites. In a few cases, the acoustic engine A5+ was unanimously approved by the audio industry experts. Jingdong direct link Acoustic engine A5+ speaker comes with a non-woven storage bag.
There is also a small storage bag that can accommodate oxygen-free copper speaker cable, 3.5mm audio cable, power cord and remote control.
The acoustic engine A5+ speaker weighs 10.8kg. The BEHRINGER B2030A speaker is a 2-channel independent power supply + amplifier and weighs 18kg.
The regulated power supply and amplifier unit are in the left speaker. Behind it is a black anodized power amplifier aluminum heat sink.
The white piano paint has a stepless volume knob on the front panel of the main box, but according to manufacturer's data, the sound engine A5+ adjusts the volume to use a digital circuit for internal volume control. This can avoid the irritating and purring noises caused by the contact oxidation when the analog volume potentiometer is used for a long time. The volume knob is also a thin film micro switch that can be immediately muted by pressing it directly, and can be restored by pressing it again. The user interaction design is still very intimate.
You can see the opposite side of the volume button is two black dots, in fact there is a white power LED and infrared remote control receiving window.
The acoustic engine A5+ speaker comes with a small and exquisite remote control, which can easily adjust the volume, mute and sleep can be easily done with a single key.
It turns out that the home artillery power amplifier in my home has no remote control, and switches and volume adjustments have to go to the front of the TV cabinet for operation. Through the sound engine A5+ infrared remote controller, you can easily adjust the sound volume of the sound engine A5+ speaker playback TV, like other set-top boxes and TVs, do not need to move around.
The acoustic engine A5+ adopts a 20mm silk dome tweeter. The tweeter of the silk membrane is soft and delicate, with good extensibility and suitable for expressing vocal and string effects. The unit uses neodymium magnets, which have a larger magnetic flux and energy product, enabling the tweeter to have better high-frequency resolution and control. The asymmetrical black plastic material around the tweeter is designed as a waveguide horn, allowing the tweeter to have better horizontal radiance, allowing the sound waves to focus on the user's central area, enabling the user to achieve better sound field positioning.
The low-frequency unit uses a 5-inch Kevlar woofer. The woofer of the speaker is always an inch larger and the 5-inch is the size of the woofer that most bookshelf boxes are designed for. Kevlar is actually a high-strength military nylon material. The diaphragm of this material has the characteristics of light weight and strong rigidity. It has a large frequency response range, low distortion, and a warm and mellow midrange frequency on the sound of hearing, deep and deep low frequency, strong and powerful. The speed and hearing resistance of medium and low frequencies can be well balanced. The speaker's material and structure are robust enough to withstand some of the larger shocks and vibrations, so there is no need to use speaker grilles that affect the sound quality, and sound and shape can still be excellent for many years.
Most circular inverting tubes have poor control of wind noise, so it's clear that the BEHRINGER B2030A and the acoustic engine A5+ have chosen slotted inverters, but only one is a dual-tube design on the front panel, and one is The single tube is designed behind the cabinet. Manufacturers claim that this design can effectively eliminate wind noise, and help the speaker to release the low-frequency energy to further enhance the sound transparency and purity.
The acoustic engine A5+ has RCA and 3.5mm input interfaces on the left side of the main loudspeaker to facilitate the connection of different devices. Through the computer's headphone jack to connect the computer and speakers, behind the interface panel also has a unique USB power supply interface and USB decoder (sound card) with a better sound quality. Both inputs are permanently activated and do not require manual switching. A set of RCA signal outputs allows you to easily pair with other audio devices, such as an active subwoofer, so that you can upgrade to a 2.1 HIFI sound system.
All the connection ports behind the speaker are gold-plated. The speaker cable is also made of high-purity oxygen-free copper wire, which effectively improves the port's anti-jamming capability and ensures that it will not be affected for a long time even in a humid environment. Oxidation prevents audio signal attenuation and distortion.
The acoustic engine A5+ speakers are arranged at both ends of the TV cabinet. The distance between the left and right channel speakers is about 1.8 meters. The seat of the emperor is 3.6 meters from the speaker.
Just hadn't had time to set up and had a good time for Fort Kai, and that night he started the "Singer 2017 Summit".
"Golden Code new upgrade", this year to see "singer" my home speakers are also upgraded it!
After the singer's signature heartbeat before the start of the singer's heartbeat kicked off, he held his breath for five seconds. His moving voice poured out like a sliver of water. Before the earliest speaker was not available, it was a fake TV at home!
"Importing younger brother Dima Xi", can raise 10key across 5 octaves! Go against the sky! On the same day, Dimahi brought the same “Kiveme loveâ€, a Kazakhstani native song that had never been published. Unfortunately, he didn’t understand much.
Last week, he joined the mango table, "Singer" "I want to sing with you" program, and then ran out a Spiderman with him to treble, be sure to change a pair of good speakers, and remember the digital high-definition set-top box to see High-definition version of the Mango Channel program can appreciate this strength showdown.
Listening to the song will make you cry. This time, the performance of the auditorium is not normal. At least 800 horses will be spent tonight!
Why did the host of this year's Summit not be Mr. He’s teacher or Wang Han and became Zhang Da’s daughter?
The thick line of advertisement was so sudden that I was completely unable to resist.
Zhang Bichen sang by "stand by"
This year the typhoon was a little weird - it was actually a week after the finals, wrestling and sitting on the couch!
This shot has a wooden special iron king feeling?
The lion choir is basically a monologue of rain gods. "Swing Together", the spirit of rock and rock to carry out the end, the atmosphere was quickly hot!
Rain God's rock style than Zhang Jieqiang!
I was not satisfied with the wall and I served Han Hong aunt. At the summit, she returned to her arrogance and chose a work that Lee Jong-sung had brewed for a full ten years - "Mountain." In order to be able to freely decide which program to host the program, she actually hosted the program on the TV station. After she retired from the army, she took a qualification certificate for broadcasting.
The inspirational model for achieving life's ideals: A veteran who does not want to be a host is not a good singer!
Sandy Lam called for "Glory King" glory this year. On the day of the summit, the new song king returned to the truth and chose the healing line “Little Love Song†to reinterpret the classics in the style of forest singing. But if she could pull Li Zongsheng to help sing it on the day of the finals, then it would be even more beautiful!
All over, this year's singer program finally came to an end.
Then the question is - Isn't TV sound suitable for monitor speakers?
I want to say not only watching TV, watching 1080p and 4K Blu-ray high-definition movies is also a very good sound transient performance monitor speakers, 5-inch low-frequency unit's dive enough, if not the effect of floor vibration, can completely without independent subwoofer .
Compared with the BEHRINGER B2030A, the acoustic engine A5+ has a warmer tuning and warmer vocals due to different materials for the bass and bass units, but the bass component is not comparable to the 5.20-inch B2030A. The bass performance is indeed an inch by inch, but listening to the B2030A's bass in the next room is obvious, but it feels like it.
But really, no matter if it is A or B, they do the living room speakers to the PO owner. This kind of user feels very painful to use - because the monitor speakers completely do not consider the function without multi-source input and switching. After all, TV cabinets generally have an Android network STB/HD player and a telecom/mobile IPTV/TV HD digital set-top box, so monitor speakers are completely anti-human unless you only look at the contents of a set-top box or use TV HDMI. The decoded audio output port is connected to the speaker input, so what the TV puts on, the speaker can really synchronize the sound automatically - but the audio output circuit of the TV is very poor in material and effect!
I enjoyed repeated insertions for more than 2 weeks. After the drawing, I waited for my dad to repair the earth artillery. However, after passing through, I continued to grow up with the AV amplifier in the second era! This is a later story, after all, this suite has completely failed in the renovation of weak electricity, and there is no embedded surround speaker cable. Therefore, the period of AV amplifiers has to be considered long-term.
