entranceWhat is l spk. Wiring diagram for front panel connectors (F_PANEL, F_AUDIO and F_USB)
If you decide to assemble or disassemble your computer, this article will be very relevant to you. It will talk about how to properly connect the panel of front buttons and USB ports on the system unit to motherboard... Here, I will consider not only general form ports to which they need to be connected, as well as the correct order in which they are connected.
In fact, it seems, there is nothing complicated about it. But in my practice, even specialists who are quite well versed in computer technology, sometimes they stand in front of the system unit, with a bunch of cables and think what and where to connect.
Therefore, further I will show in detail what and in which connector you need to connect, this or that wire for the correct operation of the connected front panel system unit... That in the future, at the next cleaning of the computer or possibly replacing the motherboard, you will have no difficulty in correctly connecting all the elements of the system unit to the motherboard.
It is also very important if your front panel with USB ports and headphone and microphone outputs does not work.... Then, be sure to read it to the end in order to find out how to fix this whole thing and return the working state to our front USB ports. Because, the malfunction may be that they are simply not physically connected to the motherboard.
Connecting the front panel, block of buttons and indicators
The block of buttons and lights for turning on and restarting is connected to the motherboard using four connectors, which are connected into one continuous loop. You can see how they look at me below. They should have approximately the same appearance in your case. Most importantly, you are looking for those connectors on which similar phrases are written: Power SW, Power LED, HDD LED. RESTART SW.
Let's take a look at each connector separately:
- POWER SW(PWRBTN) - responsible for the computer power button;
- H.D.D.LED(+ HDLED) - light bulb hard disk that constantly blinks when the computer is running;
- POWER LED - and + (PLED) - an indicator indicating the state of the computer ( enabled or disabled);
- RESTART SW(RESET) - the connector responsible for the reset button;
- - the buzzer speaker is sometimes also present in the cable panel;
Where do you need to connect all this? All connectors will connect to one port 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 you need to insert what. But still, below I will give you some examples of what to attach to what.
Also, sometimes an additional small speaker is connected, which notifies with a squeak about turning on the computer, as well as about various errors of the BIOS and computer hardware. Sometimes it connects with all the other connectors, but as a rule, a separate four pion connector is allocated for it.
Everything, with the block of buttons finished, now you can go to the front USB and audio outputs.
System unit front panel connections
The audio and USB connectors are very similar to the ones we connected for the buttons and indicators. But the most important difference between them is that they are immediately connected into one, and you do not need to take it and connect one pin at a time when connecting.
You can also find the place for connection at the bottom of the motherboard with the signatures (F_USB1, 2). There can be two or more of them on the motherboard, but it doesn't matter which one you connect to, they will work the same way. The main thing that you need to do is take a connector with the signature “ F_USB”And put it in the corresponding socket. You cannot make a mistake, because if you try to insert it on the wrong side, you simply will not succeed and turning it over with the other side, I think that everything should fall into place.
Be sure to pay attention if you have a USB 3.0, then you 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 for USB 2.0.
Connecting the front audio panel to the motherboard
The sound situation 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 USB ports and is indicated by the following abbreviations; AAFP, AUDIO, А_AUDIO.
Taking the connector with the inscription " HD Audio" or " AC 97"We plug into 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 in BIOS it is worth checking the settings of the front audio panel. Sometimes it happens that the system uses the "AC97" driver, and the BIOS specifies "HD Audio" that, due to a mismatch, make our audio outputs inoperative.
Connecting additional fans
I think that information about how and where you can connect additional fans will not be superfluous for you. I mean those coolers that can be located on the back of the case or stand in the bottom of it. The procedure is the same as before, we 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 somewhere 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 also want to note that there is a small wall on the connector itself, which serves as a hint for correct connection... The connector itself should sit easily, if this is not the case for you, most likely you are trying to connect it on the wrong side. I do not recommend pushing it there by force; there is a possibility that you will simply break it off.
Well, it seems that everything, additional elements, cases 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 for the sake of completeness.
Connecting the computer's front panel to the motherboard
As is often the case, we began the review of a new stereo pair with a study (or rather, with a repetition - the company is not a beginner) of all SVEN products in this segment. We load the official website www.sven.ru, section " Catalog / multimedia acoustics 2.0 ".
We counted about 20 models - potential buyers-fans of "the only correct 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 - columns marked with as many as six quality marks from various reputable publications and, by the way, who once visited our laboratory.
However, today we will talk about something else. We have to evaluate the acoustics SvenSPS-700- a classic active full-size stereo pair. Go.

Design, ergonomics, functionality
So, both speakers with a set of wires are taken out into the light. Let's start our inspection.
There is only one wire for connecting to a sound source, 2RCA mini Jack - more suitable for connecting the speaker to a PC. To reproduce sound, for example from DVD, you need a wire with two pairs of "tulips".
The passive speaker is connected to an active connecting wire RCA mini Jack, the length of which is 130 cm is enough to conveniently place the system on a table or shelf.
The power cable for connecting the amplifier built into the AC to a 230 V, 50 Hz network, as is often the case, is not detachable. Its length is also sufficient with a margin.
Let's go directly to the columns. A classic black copy came to our test, 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 liking.
Down with the plastic - the speaker cases are wooden, made of 8 mm MDF boards and covered with decorative foil. There are no frills in the form of rounded corners or ribs - the speakers should sound good first of all, and design elements are a secondary matter, although such strict classics have always been held in high esteem.
As has already become evident from technical description and photo speakers, two-way speakers, with standard layout speakers: treble over bass / midrange. The broadband has soft rubber suspensions and a diffuser made of impregnated fabric, the magnetic system is shielded. The dome tweeter (also fabric) is acoustically loaded onto a small horn.
To protect them from dust, the speakers are covered with a black grill made of acoustic fabric stretched over a wooden frame. The protective mesh is removable; it is attached to the case by means of four plastic pins.
Conveniently, this model implements control functions. A small panel with controls is located on the right side of the active speaker. It is slightly recessed, which will additionally help when orienting by hand. The idea of the engineers to place the toggle switch for turning on the system (made in the form of a regulator with two positions) also on this panel turned out to be successful - now there is no need to reach for the back wall at all.
In addition to the switch, the panel contains standard volume and tone controls. All handles are provided with explanatory inscriptions, have a pleasant taut stroke, and there are also indicators of the current and end positions.
Let's move on to the rear walls of the speakers. In the passive one, it is solid wood, with a single RCA jack for the connecting cable.
A similar wall of the active column is hybrid - half of the area is occupied by a metal panel, which also serves as a radiator. It houses the AUDIO IN input connectors, a mini Jack output for the L-SPK connecting cable, and a "mini jack" audio output for possible connection subwoofer SUB OUT (selectable). The red LED indicator will indicate whether the speaker is connected to the network.
At the end, let us note with a couple of phrases the type of acoustic design of the acoustics. The loudspeaker cases are bass-reflex, with a slotted FI port located on the bottom of the front panel. Such an 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 in some way, perhaps listening will show.
Listening
So what to expect (or not to expect) from the system in terms of sound? Here it should be admitted that it is unlikely that it will be possible to sound a large speaker room with high quality. Rather, its purpose is direct sound accompaniment of the workplace (films, music, games). Convenient control will always allow you to quickly adjust to the right moment, and the quality of the design will not make you regret the perfect purchase.
What do we mean by speaking in this way? Firstly, the speakers do not trite wheeze at maximum volume. At an average (comfortable) volume, the sound is quite musical. Yes, some tones change, slightly hysterical notes appear, but the sound remains a little cold, with a slightly squeezed middle, dry, but with sufficient attack bass and crumbly, airy highs.
Secondly, the tonal balance is not disturbed by ear, so there is no strong need to experiment with the settings. We set HF to "one or two", and LF - "to an hour".
And thirdly, this is a fact. Sometimes, for greater objectivity, we study the statements of happy users about the described product, and then we try to verify their conclusions. So, on the Internet, we were greeted with the judgment that these speakers, due to the slotted port of the FI, sin with directivity, and the sound in a meter or two has a different color. Well, the opinion is subjective, but surely it is 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 possibility to connect a separate subwoofer to good speakers looks really sober.
Conclusion
So the model SPS-700 the SVEN company has proved itself worthy in our synopsis... A well-made, inexpensive stereo pair is perfect for full-fledged sounding of a workplace at a computer or a small room in general.

This picture shows the motherboard connectors for connecting connectors.
Basically (there are exceptions) under the connectors, the order of connecting the connectors and the polarity are written in small print. In my case, it says:
PWR_LED (three connectors) - indication of the switched on computer;
PW- (PWRSW) - PC power on button;
RES + (RESET) - button to restart the PC;
HD- (IDE_LED, HDD_LED) - hard disk access LED;
SPEAK- (SPEAKER) - 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, it is enough to turn it over to the back side - we see on opposite one of the wiring a small black triangle - this is "+".
We proceed to the next stage, connecting the front additional USB connectors and a card reader to the F_USB2 and F_USB1 connectors (there is no difference, but it is 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 plug this "big" connector consisting of: eight wires, one empty and one soldered connector (ten in total) so that the EMPTY connector matches the SEALED socket in the connector. (see screenshots)
But, if you have a bundle of wires as in the picture, I will 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) to another port. As you may have guessed, the two POWER connectors are identical and can be swapped, just like GND. The main thing is not to confuse the places of POWER and GND.
So now it remains 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 10-slot connector from the front panel, just insert it (you definitely can't go wrong here). My case is more interesting ... :) 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.
In a high-quality audio system, the main role is assigned to stereo or multichannel speaker systems.

Thanks to them, electrical impulses are converted into sounds of the acoustic range of different frequencies. Someone cares about a clean sound that is as close to the original as possible. musical instruments, but for someone the voice of a vocalist, film actors or a teacher from training video courses is in the first place.
How important is a speaker system?
It is the base for the entire audio system.
It is preferable to start the selection of a suitable audio system with acoustics.
Moreover, for each different equipment options will be a priority. The choice is influenced by such factors as the "sharpening" of such a system for those genres that are to the liking of the future owner and the price category.
For lovers of the most accurate sound, hi-fi speakers are suitable.
Despite the myths, not every expensive audio equipment shows the mentioned possibilities.
In the case where exclusive comes first, the audio systems market provides fans of high-quality sound with Hi-End audio equipment.
Reference! High end Is a marketers' term indicating the elitism of software and hardware to enhance the sound. Accordingly, the price of such audio systems does not scare only ardent fans of music or fans of non-serial audio equipment with a good financial condition.
Speaker types
There are several categories of loudspeaker systems, each of which is capable of meeting specific customer needs. According to the basic differences, there are 5 basic classification groups.
- The principle of installing the equipment. Speaker systems are divided into floor-standing and shelf-based, depending on their size. The former are preferred for large spaces such as cinemas. Using them at home for a TV or computer is unprofitable. It is more optimal to use bookshelf speakers.
- Number of speakers. This is also called dividing by the number of sound strips. The manufacturer can include from 1 to 7 speakers. The most optimal option for a budget is 3 speakers, where one band is responsible for the low frequencies, the other for the middle and the third for the high.
- 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 preferable for audiophiles due to the crossover filter and, accordingly, more High Quality sound due to frequency division.
- By design, the speakers differ into planar, dynamic, electrostatic and other types, and in some cases the equipment does not fall into any category.
- Registration. The speakers can have a closed or open case; a good addition would be a phase inverter - a pipe in a speaker tuned to a certain frequency and amplifying sounds within it. Thanks to this hole, lower frequencies are reproduced than with conventional equipment. If the pipe is bent inside the cabinet, increasing its length, power and the range of reproducible low frequencies, you get speakers with an acoustic labyrinth. They are more expensive and require more precision to manufacture.
Areas of use of speaker systems
The first and main area of application is home use.
This includes the need for quality sound for a more complete immersion in video games, the power and strength of sound for watching TV, clarity and closeness to the original sound for music lovers of various genres.
Lovers of high-quality music in the car are advised to purchase multi-band audio systems.
Moreover, for the best sound in the front of the car there are high-frequency and mid-frequency elements of the Car-system. The low-frequency speakers are often assigned to the rear auto.
Concert versions of speaker systems are designed not only to provide sound access to any point in a large room or hall, but also to meet the requirements of many listeners for sound quality. The most common sets of audio equipment for concerts include monitors for transmitting nuances of sound, front speakers for direct sound with high density, center speakers for transmitting vocals.
L spk on speakers
A separate category is recording studios. For them, studio monitors are preferable, which are able to reproduce sound with all its pluses and minuses, which ultimately contributes to the creation of a cleaner and more reliable track.
Regardless of where the speaker system will be used, it is recommended to preliminarily determine the criteria by which the selection of suitable equipment will take place.
With their help, it will be possible to obtain equipment that can bring you as close as possible to the sound of your dreams.
