Thanks to them, electrical impulses are converted into sounds in the acoustic range of different frequencies. For some, the pure sound of musical instruments that is as close as possible to the original is important, but for others, the voice of the vocalist, film actors, or teacher from educational video courses comes first.

How important is the sound system?

It is the basis for the entire audio system.

It is preferable to start selecting a suitable audio system with acoustics.

Moreover, different equipment options will be a priority for each. The choice is influenced by such factors as the “tailoredness” of such a system to those genres that the future owner likes and the price category.

For lovers of the most accurate sound, hi-fi speaker systems are suitable.
Despite the myths, not every expensive audio equipment offers the mentioned capabilities.

When exclusivity comes first, the audio market provides fans of high-quality sound with Hi-End audio equipment.

Reference! High End is a marketing term that refers to the elite quality of software and hardware that enhances sound. Accordingly, the price of such audio systems does not scare only ardent music fans or lovers of non-serial audio equipment who have a good financial condition.

Speaker types

There are several categories of speaker systems, each of which is capable of satisfying specific customer needs. Based on basic differences, there are 5 basic classification groups.

• The principle of equipment installation. Acoustic systems are divided into floor-standing and bookshelf depending on their size. The former are preferable for large premises such as cinemas. Using them at home for a TV or computer is unprofitable. It is best to use bookshelf speakers.
• Number of speakers. Otherwise, this is called division by the number of sound bands. The manufacturer may include from 1 to 7 speakers. The most optimal option for the budget is 3 speakers, where one band is responsible for low frequencies, another for middle frequencies and a third for high frequencies.

• The presence or absence of a sound amplifier in the speakers. In the first case they are called active, in the second - passive. Passive options are much more common. They are preferred by audiophiles due to the crossover filter and, accordingly, higher sound quality due to frequency separation.
• By design, speakers are divided into planar, dynamic, electrostatic and other types, and in some cases the equipment does not fall into any category.
• Design. Speakers can have a closed or open body; a good addition would be a bass inverter - a pipe in the speaker tuned to a certain frequency and amplifying sounds within its limits. Thanks to this hole, lower frequencies are reproduced than with conventional equipment. If the pipe is bent inside the housing, increasing its length, power and range of reproduced low frequencies, you will get speakers with an acoustic labyrinth. They are more expensive and require greater precision in manufacturing.

Areas of use of acoustic systems

The first and main area of ​​application is home use.

This includes the need for high-quality sound for greater immersion in video games, power and strength of sound for watching TV, clarity and proximity to the original sound for music lovers of various genres.

Fans of high-quality music in the car are recommended to purchase multi-band audio systems.

Moreover, for better sound, high-frequency and mid-frequency elements of the Car system are located in the front of the car. Low-frequency speakers are often assigned to the rear of the car.

Concert versions of acoustic systems are designed not only to provide sound access to any point in a large room or hall, but also to satisfy the sound quality requirements of many listeners. The most common concert audio packages include monitors for nuanced sound, front speakers for high-density direct sound, and center speakers for vocals.

L spk on speakers

A separate category is recording studios. They prefer studio monitors that are capable of reproducing sound with all its pros and cons, which ultimately contributes to the creation of a purer and more authentic-sounding track.

Regardless of where the speaker system will be used, it is recommended to first determine the criteria by which suitable equipment will be selected.

With their help, you will be able to get equipment that will bring you as close as possible to the sound of your dreams.

This picture shows the motherboard connectors for connecting connectors.

In general (there are exceptions), under the connectors the order of connecting the connectors and polarity are written in small print. In my case it says:

PWR_LED (three connectors) - indication of the computer being turned on;

PW- (PWRSW) - PC power button;

RES+ (RESET) - button to restart the PC;

HD- (IDE_LED, HDD_LED) - hard disk access LED;

SPEAKER (SPEAKER) is the same signal(s) that the computer emits when turned on if an error is detected.

The connectors look like this (see screenshots)

Each connector has two wires:

POWER LED (green, white);

H.D.D. LED (yellow, white);

POWER SW (black, white);

RESET SW (orange, white);

SPEAKER (black, red).

In this case, white is minus “-” or Ground, and colored is “+”. The SPEAKER connector (black, red) has a black “+” and a red “-”. To determine the polarity of the connectors, just turn it over to the back side - we see a small black triangle on the opposite side of one wire - this is “+”.

We move on to the next stage, connecting the front additional USB connectors and the card reader to the F_USB2 and F_USB1 connectors (there is no difference, but it’s better to start in order). If the connector is already “soldered”, i.e. All wiring is collected in one block - the process is greatly simplified.

We simply connect this “big” connector consisting of: eight wires, one empty and one sealed connector (ten in total) so that the EMPTY connector coincides with the SEALED socket in the connector. (see screenshots)

Well, if you have a bundle of wires like in the picture, I’ll draw a visual diagram :)

Here we see: POWER (Power - 2 pcs.), GND (Ground - "ground" 2 pcs.), D3+ (plus), D3- (minus) for one usb port and D2+ (plus), D2- (minus) for different port. As you may have guessed, the two POWER connectors are identical and can be swapped with each other, just like GND. The main thing is not to confuse POWER and GND.

So now all that remains is to figure out how to connect the F_AUDIO connectors for the microphone and headphones.

Again, if you are lucky and there is a large block with 10 sockets coming from the front panel, just insert it (you definitely can’t go wrong here). I have a more interesting case... :) Ah, these are the connectors: SPK R (right channel output to the front panel), SPK L (left channel output to the front panel), MIC (microphone output to the front panel) and GND.

As often happens, we began our review of a new stereo pair by studying (or rather, repeating - the company is not a newcomer) all SVEN products in this segment. Loading the official website www.sven.ru, chapter " Catalog/multimedia acoustics 2.0".

We counted about 20 models - potential buyers who are fans of the “only true format” will have plenty to choose from. Some sets are less well known here, others have already gained some public attention. At the very end of the proposed list are Sven Royal 2 - speakers marked with as many as six quality marks from various authoritative publications and, by the way, which were once in our laboratory.

However, today we will talk about something else. We have to evaluate the acoustics SvenSPS-700- classic active full-size stereo pair. Go.

Design, ergonomics, functionality

So, both speakers with a set of wires are brought out into the light. Let's start the inspection.

There is only one wire for connecting to the sound source, 2RCA mini Jack - more suitable for connecting speakers to a PC. To play sound, for example from a DVD, you will need a wire with two pairs of “tulips”.

The passive speaker is connected to the active speaker via an RCA mini Jack, the length of which is 130 cm and is enough to conveniently place the system on a table or shelf.

The power cable for connecting the amplifier built into the speaker to a 230 V, 50 Hz network, as is often the case, cannot be disconnected. Its length is also sufficient to spare.

Let's move directly to the columns. A classic black specimen came to us for testing, although there are others: walnut, silver. As you can see, the choice is varied, and surely everyone will be able to choose a color to their taste.

Down with plastic - the speaker bodies are wooden, made of 8 mm thick MDF boards and covered with decorative film. There are no frills in the form of rounded corners or ribs - the speakers should first of all sound good, and design elements are a secondary matter, although such strict classics have always been held in high esteem.

As has already become noticeable from the technical description and photo of the speakers, the speakers are two-way, with a standard arrangement of speakers: HF above LF/MF. The broadband speaker has soft rubber suspensions and a diffuser made of impregnated fabric; the magnetic system is shielded. A dome-type tweeter (also fabric) is acoustically loaded onto a small horn.

To protect against dust, the speakers are covered with a black grill made of acoustic fabric stretched over a wooden frame. The protective mesh is removable and is attached to the body using four plastic pins.

Control functions are conveniently implemented in this model. A small panel with controls is located on the right wall of the active speaker. It is slightly recessed, which will additionally help with hand orientation. The engineers' idea to place a toggle switch for turning on the system (made in the form of a regulator with two positions) also turned out to be successful - now there is no need to reach the back wall at all.

In addition to the switch, the panel contains standard volume and tone controls. All handles are equipped with explanatory inscriptions, have a pleasant taut action, and also have indicators for the current and extreme positions.

Let's move on to the rear walls of the speakers. The passive one is made entirely of wood, with a single RCA socket for the connecting cable.

A similar wall of the active speaker is hybrid - half of the area is occupied by a metal panel, which simultaneously functions as a radiator. It houses AUDIO IN input connectors, a mini Jack output for the L-SPK connecting cable, as well as a “mini-jack” audio output for possible connection of a SUB OUT subwoofer (you can select). A red LED indicator will indicate whether the speaker is connected to the network.

At the end, let us note in a couple of phrases the type of acoustic design of the acoustics. The speaker housings are bass reflex, with a slotted FI port located on the bottom front panel. This arrangement will allow you to place the speakers close to the wall, without fear of distorting the sound of the system, but such a special shape of the bass reflex port will affect it in some way, perhaps showing listening.

Listening

So, what can you expect (or not expect) from the system in terms of sound? Here it should be admitted that it is unlikely that it will be possible to provide high-quality sound in a large speaker room. Rather, its purpose is direct sound accompaniment of the workplace (movies, music, games). Convenient controls will always allow you to quickly adjust at the right moment, and the good quality of the design will not make you regret your purchase.

What do we mean by saying this? Firstly, the speakers do not simply wheeze at maximum volume. At medium (comfortable) volume the sound is quite musical. Yes, some tones change, slightly hysterical notes appear, but the sound remains the sound - slightly cold, with somewhat compressed mids, dry, but with sufficient attack in the bass and crumbly, airy highs.

Secondly, the timbral balance is not disturbed by ear, so there is no strong need to experiment with the settings. We set the HF for “an hour or two”, and the LF for “an hour”.

Well, thirdly, this is a fact. Sometimes, for greater objectivity, we study the statements of happy users about the product being described, and then try to verify their conclusions. So, on the Internet we came across a judgment that these speakers, due to the forward slotted FI port, suffer from directivity, and the sound within a meter or two has a different color. Well, the opinion is subjective, but it’s probably based on something, and therefore we have no right to refute it. Let's just say that this was not noticed with our specimen. By the way, stereo pairs are not always “friendly” with soft, deep bass, and therefore the provided opportunity to connect a separate subwoofer to good speakers looks really sober.

Conclusion

So the model SPS-700 SVEN company proved itself worthy in our brief review. A well-made, inexpensive stereo pair is perfect for full-fledged sound recording of a computer workplace or a small room as a whole.

If you decide to assemble or disassemble a computer, this article will be very relevant for you. It will discuss how to properly connect the panel of front buttons and USB ports on the system unit to the motherboard. Here, I will consider not only the general appearance of the ports to which they need to be connected, but also the correct order when connecting them.

In fact, there seems to be nothing complicated about this. But in my practice, even specialists who are fairly well versed in computer technology sometimes stand in front of a system unit with a bunch of cables and think about what needs to be connected and where.

Therefore, below I will show in detail what and in what connector this or that wire needs to be connected for the correct operation of the connected front panel of the system unit. That in the future, the next time you clean your computer or perhaps replace the motherboard, it will not be difficult for you to correctly connect all the elements of the system unit to the motherboard.

It is also very important if the front panel with USB ports and outputs for headphones and microphone does not work.. Then, be sure to read it to the end to find out how to fix this whole thing and return our front USB ports to working condition. Because the problem may lie in the fact that they are simply not physically connected to the motherboard.

Connecting the front panel, button block and indicators

The block of buttons and light bulbs for turning on and rebooting is connected to the motherboard using four connectors, which are connected into one continuous cable. You can see what they look like for me below. They should have approximately the same appearance for you. The main thing is to look for those connectors that have similar phrases written on them: Power SW, Power LED, HDD LED. RESTART S.W.

Let's look at each connector separately:

• POWER SW(PWRBTN) - is responsible for the computer power button;
• H.D.D.LED(+ HDLED) - hard drive light that constantly blinks when the computer is running;
• POWER LED - And + (PLED) - indicator indicating the state of the computer ( enabled or disabled);
• RESTART SW(RESET) - connector responsible for the reset button;
• - the tweeter speaker is sometimes also present in the cable panel;

Where should all this be connected? All connectors will connect to one port, which is located in the lower right corner of the motherboard. Manufacturers usually sign them with such designations as: “ F_PANEL" or simply " PANEL" On each motherboard, near such a panel, there are small signatures where what needs to be inserted. But still, below I will give you several examples of what to add to what.

Also, sometimes an additional small speaker is connected which notifies with a squeak that the computer is turned on, as well as about various BIOS and computer hardware errors. Sometimes it is connected with all the other connectors, but as a rule, a separate four-pion connector is allocated for it.

That's it, we're done with the button block, now we can move on to the front USB and audio outputs.

System unit front panel connections

The audio and USB connectors are very similar to those we connected for buttons and indicators. But their most important difference is that they are already immediately connected into one, and when connecting you do not need to take it and connect it one pin at a time.

You can also find the place for connection at the bottom of the motherboard with labels (F_USB1, 2). There may be two or more of them on the motherboard, but it doesn’t matter which one you connect to, they will work the same. The main thing you need to do is take a connector labeled “ F_USB"and put it in the appropriate connector. You can’t make a mistake, because if you try to insert it the wrong way, you simply won’t succeed, and turning it over to the other side, I think everything should fall into place.

Be sure to pay attention if you have on the front panel of your computer USB 3.0, then you will need to connect it to the appropriate connector. You can find out where it is located in the manual for your motherboard. Also, I want to draw your attention to the fact that if USB 3.0 is connected to a standard connector, it will work, just the transfer speed will be the same as on USB 2.0.

Connecting the front audio panel to the motherboard

The situation with sound is similar to USB. Here, too, the connectors are connected into one, which will allow you to easily and without errors connect it to the motherboard. The connector itself is usually located next to the USB ports and is designated by the following abbreviations; AAFP, AUDIO, A_AUDIO.

Taking the connector with the inscription “ HD Audio" or " AC 97"We connect to the connector with one of the signatures, an example of which I indicated above. If after connecting the headphones and microphone still do not respond, then you should check the settings of the front audio panel in the BIOS. Sometimes it happens that the system uses the “AC97” driver, but the BIOS indicates “HD Audio”, which, due to mismatch, renders our audio outputs inoperative.

Connecting additional fans

I think that information on how and where you can connect additional fans will not be superfluous for you. This means those coolers that can be located on the back wall of the case or stand in its lower part. The procedure is the same as before, take the connector and plug it into the connector. True, the location of the connectors is different from all the others. In most motherboards it is located somewhere approximately in the middle and looks like this.

Also, as in all other cases, each connection point has its own signature (SYS_FAN, CHA_FAN). I would also like to note that there is a small wall on the connector itself, which serves as a hint for correct connection. The connector itself should fit easily; if this is not the case, most likely you are trying to connect it on the wrong side. I don’t recommend pushing it there by force; there is a possibility that you will simply break it off.

Well, it seems like everything, additional elements, housings that will need to be connected, I remembered. But if I forgot something, you will remind me in the comments and I will add this information to this article to complete the picture.
