0.6 square meter ultra-small desk audio system upgrade

In fact, the reformation has been going on for quite some time. When the room was sorted out this weekend, I thought I could share it with you (by coinciding with the coins) and I had this article.

Pit background

After hitting the children and starting elementary school, he gave up his own study to his son. So, the once spacious computer desk became a small table that is now less than a square meter. This is the “0.6 square meter” in the title of the article. The origins. Although I am not a music fancier and do not pursue Hi-Fi, there are still some requirements for the quality of audio equipment. After listening to the set of desktop stereos on Lao Zhang’s hands, I always feel the music from the computer + active speakers. It is very light and lacks a sense of fullness and fullness. The “taste” is also a lot worse. I think maybe this is the difference between a professional audio amplifier and a small amplifier built into an active speaker. So cheeky borrowed from the old wife Zhang audio amplifier part and a pair of speakers, connected to the computer, the effect is suddenly very different! However, the problem also followed. First of all, this is only a temporary borrowing and it needs to be returned. Second, a square meter of the table is already very crowded, and it is really awkward to use a power amplifier and speaker. Thus, the idea of ​​giving yourself a compact desktop power amplifier was born.

Desktop situation before the transformation

As I said earlier, it has been transformed for some time. Therefore, before the reconstruction, I did not want to mention it. I had to briefly describe it. I drew a sketch to facilitate understanding. . . . Since I prefer photography, I often need PS photos, but I'm poor, so the monitor bought a 27-inch 2K resolution display that is the same as the iMac (old version). Due to the early buy, the display border is very thick. Placed on the table almost fills the width of the entire table 3/4, the right side barely squeezed into a desktop computer host. In this way, the horizontal width is all used. Before using a pair of innovative T20 desktop active speakers, the slim shape, barely can be placed behind the monitor, but the two speakers can not let go.

Transformation + purchase process

The first problem of the transformation was to solve the problem of no place for the horn. A small table would not be expected to be put down. After much deliberation, it had to develop on the wall and finally decided to put a shelf on the wall. Naturally, Ikea went to the front door to buy, pick and choose, and finally did not choose the general wooden shelf, but chose a metal shelf with mesh, called ALGOT, but be careful that this is not a thing, put Plates, hanging strips, and brackets are sold separately, and three things are called ALGOT. When you buy them, you have to look at them. You have to calculate and measure them in advance and choose the appropriate width, depth, and number of layers.

After returning home for a crazy drill with a hammer, after the dust was flying, the shelf was finally put on. Due to the good size, the speaker was perfect on the wall!

Then I would like to reduce the space occupied by the display by the way. Because the display itself is heavy, the base is particularly large and occupies a large area, causing the surrounding to be unable to put things. So choose to simply throw away the base, replaced by iQunix aluminum display bracket, not only allow the display to maintain its height, you can also put the original no place to put the keyboard to the monitor down, all of a sudden a lot of fresh desktop! And the monitor can also move forward to give more space behind. Here I put a storage box by the way, put all kinds of cables, transformers into it, the back space can also be used as a mobile hard disk storage.

It was previously known on Jingdong and other crowdfunding platforms. The series of products of the audio teacher Zeng Dexuan, all with the appearance of an old-fashioned radio, combined with a purely hand-made wooden shell, the whole is very retro, and it is full of memories. This time is the smallest and smallest version of the mini-prince. Elvis MAOKING Little Prince Walnut Wood Portable Bluetooth Speaker YYJJPP | Likes 5 Comments 15 Collections 25 View Details

Aunt Bluetooth audio I wrote out of the box

The space problem is solved. The following is the question of which of the key power amplifiers to buy. Originally, I would like to simply buy a stereo sound, but I feel that using some egg pains is not only expensive, but also the bulky problem is still not resolved, and in order to save money I wanted to use the set of Philips stereo speakers I bought when I was married (the host was obsolete), so I wanted to buy a pure power amplifier. A compact power amplifier could easily be placed next to my monitor. In addition, because he will usually play some other audio equipment, such as electronic synthesizer, you need to connect iPad, and then output sound from the iPad headphone jack, so you also need this amplifier can simultaneously connect at least two devices, that is, there are two Audio input interface.

Since I didn't understand this kind of thing, I first consulted a friend about it. My friend's idea is not to buy homemade no-name products and the quality is worrying. The rest can be selected according to their own budget and functional requirements, friends first help me from a simple search a few brands, Nuforce, NAD, Denon, let me pick from inside. This was not heard except for Denon Denon. After a brief search, I found that the other two are still well-known in the professional field. Didn't expect the brand of this category to be so small? I do not give up, go to Taobao search yourself, first try the keyword "desktop amplifier", arranged by sales, the results are as follows:

The first few dozens of products are domestic brands (I may not know), from more than 200 to more than 600, the first foreign brand is NAD's D3020, prices ranging from 3100 to 3999, followed by Tianlong PMA-50, price 4380, Nuforce basically did not see. Try changing the keywords again, "2.0 amplifier", arranged by sales, hey! There is a more famous Yamaha, and as long as more than 1200! ! ? There are more than 1,600 Bluetooth versions. Isn't this very good? The results are tapped into the details page. . . Was crying in size by size, and the size of the home theater's big amplifier was just a little thin. . . My desk is completely out of place. . . The function is basically in line with my requirements, but unfortunately, had to give up.

As for the Nuforce that I haven't seen yet, I had no choice but to search directly for the “Nuforce Amplifier.” Finally I found it, and there was a Tmall shop. Look, there is only one model called Icon HDP for the amplifier model. The other is a small amp. , or tens of thousands of big amps. Saying that this basically meets my needs, computers and amplifiers can be connected using a USB sound card, you can also use the motherboard's own fiber connection, and iPad devices use a red and white lotus head line 3.5mm connection.

But in the end I chose the N30 D3020 because the D3020 interface is more plentiful, supporting fiber, coaxial digital input, subwoofer output excuse, Bluetooth, and a remote control. Although there is a small Bluetooth speaker, the effect is not comparable to that of a large speaker. In this case, the bedroom is equivalent to a wireless audio system. You can use your mobile phone to play high-quality music in your room through Bluetooth. Now.

Official website of the NAD brand, read a long time do not know which country's brand, their online search for a bit to know that the United Kingdom.

Purchase process

In fact, the procurement process need not say more, online orders, and then courier sent to just fine. However, I was not buying it on Taobao, Tmall, or Jingdong. Instead, it was introduced through that friend and purchased on NAD's official website. It was wrong. It could not be said to be the official website. It was their own domestic e-commerce platform. , and bought a D3020 and a pair of Klipsch Reference On-ear headsets (see website, guess they should also be Klipsch's agent), because friends just want to buy this headset, the official website of a single product price and Taobao no difference, However, the total price of the package is cheaper than buying it from Taobao alone, and the headset is only worth half the original price. Of course, the two are divided equally. So the final price I got was 2,800.

There is no difference between the website and Taobao, but I am too lazy to sign up for an account and let my friends help me to place an order. He is an audiophile, and some of the audio equipment that Jingdong/Taobao cannot buy will be bought from other internet platforms. So more accounts. After the order was placed, SF was able to send the product home.

Unpacking & Installation

Simple to open a box, the appearance is very plain, green cardboard packaging, which in addition to the host, there is a remote control, a power cord, a fiber optic adapter, instructions and 4 step stickers, a little simple, As a decoder that can connect to a computer, send at least one USB cable, and it is still not very common USB Type-B port, but fortunately I have a 3.5-inch mobile hard disk line can be used.

The headset inside the suit was not removed. It was taken to a friend the next day.

Take out the mainframe after opening the box, the first feeling, all plastic, texture is generally like ~ Both sides use a rubber-like coating, while the middle one is a smooth and bright surface. The glossy surface was protected with a film, but the foil was actually lifted when it was packaged. This package level...there is a lot of interfaces on the back. In addition to those commonly used interfaces, there is actually a separate subwoofer output, a stranger. The 12V Triger interface, checked on the Internet, was originally used as a dedicated interface for connection to the smart home. In addition, the AUX 2 audio input looks like a 3.5mm jack, but it is written Optical 2 and is estimated to be the fiber interface. It is necessary to use an ordinary square fiber head with a random converter to 3.5mm. Random remote control design is very cute, above the thin thick shape, pinch in his hands very comfortable.

After reaching the hand, first try to connect the notebook computer and Lao Zhangren's horn to see how the connection is better. After the test, put it on the computer desk to install. When the problem is solved, it will be reworked in such a small space.

Suddenly found that a full set of things are black, computers, decoders, speakers, mobile phones, remote controls, wire...

The picture above is the same as before it was connected. Looking at it is quite refreshing, but I can imagine it is not so beautiful after connecting. ~~ Look at the picture below:

Because of its small size and its many rear interfaces, it's more cramped when connecting various cables. The above picture shows the connection method in the case where all my requirements are met, including the USB cable connecting the computer and the speaker cable connecting the speaker. Connect the red and white head input port of the second audio source (iPad or mobile phone), and then the lower power cord. Speaking of power, this machine has a built-in power supply. This is good, and it won't drag a big transformer outside. Here, it is found that the design of the two speaker terminals is somewhat unreasonable. The two pairs of terminals are in close proximity, and the fingers are not easily screwed. After a hard twist, the copper wire holes on the terminals are straight up and down, making it particularly difficult to install. Lao Zhang’s old stereo design is inclined at 45 degrees, which is very convenient.

It was only after the arrival that the goods except the volume control was the knob mode operation, and other such as the power switch and the audio source switching were operated through the top two touch buttons. Although stylish, but. . . If I put it behind the monitor, I need to stretch my neck to see where the button is and then press it. I can't do it blindly. If the touch button can have a bump or a stamp that can be touched, this problem can be solved perfectly.

Connected to the computer, actually do not need to drive, Windows 10 directly recognized, and even "is looking for installation driver" tips did not jump out, the horn sounded directly, but it saves a lot of things, yes. The sound is better than the sound quality of the original PC motherboard integrated sound card plus active trumpet. I do not know how many times, the sound is full, the sound field is wide, and the three-dimensional feel is a lot stronger. It is the kind of sound that closes your eyes like a band. In front of the feeling of performance. Obviously can feel a lot of resolving power of the sound, but the bass is a little weaker, for me like this only listen to "move times hit" pop music, the taste is a bit light. After looking at the instructions, I found that there was a super-small Bass EQ button behind it. I didn't notice it at first. Click once, and the bass sounded out. The sound was good and the sound was satisfactory.

Switch the sound source through the top S button (Source), the front panel will have a corresponding letter to display the current status, try Bluetooth connectivity, switch to BT, search and connect the phone, you can immediately enjoy the wireless sound effects, compared to The little prince customized speaker on the table sounds much better~

The next step is to clear the table, remove the original sound, and replace the D3020 decoder. The following figure is the original old sound, in addition to a big point, the other is very good, all the physical buttons, and the size, shape, location are different, the dark night of fire to operate without error.

Put on D3020, the effect is as follows, the desktop feels more comfortable, behind the storage box can also put two 3.5-inch mobile hard disk box. However, there is a problem that cannot be solved for the time being, because the horn is on the wall, so it is bound to drag down the two horn lines. However, fortunately the monitor is large enough to barely drag it.

A summary of several advantages and disadvantages of this NAD D3020:

advantage:

1. Rich interface, can connect multiple devices, wide application;

2. Small size, flexible arrangement, and space saving;

3. The sound effect satisfied me;

4. The subwoofer can be extended (although I think that is not HiFi).

Disadvantages:

1. General workmanship, material quality;

2. The speaker terminal design is not reasonable;

3. Touch design is not suitable for closed-eye operation;

4. Randomly missing the necessary USB cable.

Oh yeah, I forgot to say how the monitor dropped the pedestal. Because the monitor is particularly heavy, it has 10KG! ! The general brackets can not withstand, the price of affordable brackets on the sky. Since there was no room for adjustment, the base of the iQunix below was chosen, and the cheapest display stand was chosen to support the display from behind, and the display stood directly on the base.

The above is the transformation of my 0.6 square meter writing desk, mainly for audio, now the computer's sound effects on several grades, I have been very satisfied, and because the decoder with Bluetooth, the whole room is equal to more than a wireless Bluetooth audio . By the way, shelves are installed on the wall of the desk, which improves the base of the monitor and expands the storage space of the desktop. At present, we are satisfied with the function, that is, the wire is still a bit messy and we need to continue to work hard. Of course... The king is still changing big houses. . .
