I asked about the sound card, how to use the sound card

It's 4 satellite speakers + 1 subwoofer (CH is channel, yes channel) is 5 satellite speakers + 1 subwoofer.

It's 7 satellite speakers + 1 subwoofer.

I use Creative Gigaworkss750 (surround speakers and.

X-Fi Fatal1ty sound card.

With Creative MediaSource 5, you can convert CD2ch physical audio tracks into surround digital audio files (200MB-700MB...).Liuhan. But it's by no means a regular CD that can match, especially the effect of non-pop **!

It's amazing. For example, Titanic CD or something).

I highly recommend!!

Excuse me. I don't know what a good sound card is under 300.

A sound card with a 5MB amplifier chip, which can adjust the volume on the sound card. There are functions of exciters and effects. It's an ISA slot, so it can't be expensive. About 200 yuan.

If you only listen to songs, I suggest you buy cheaper

With the innovation bar, the channels are all the same, and the function is stronger!

Sound card (sound card) is also called audio card (Hong Kong and Taiwan call it sound effect card): sound card is the most basic component of multi-technology and is a kind of hardware that realizes the mutual conversion of sound wave digital signals.

The main function of the sound card is to convert the original sound signal such as microphones, tapes, discs, etc., and output them to sound devices such as headphones, speakers, amplifiers, tape recorders, etc., or to make musical instruments produce wonderful sound through MIDI.

At the same time, the sound card can obtain the sound analog signal from the microphone, and through the hardware analog-to-digital converter, the sound amplitude signal is sampled and converted into a series of digital signals and stored in the computer.

How it works:

The sound card obtains the sound analog signal from the microphone, and through an analog-to-digital converter (ADC), the sound wave amplitude signal is sampled and converted into a string of digital signals, which is stored in a computer.

During playback, these digital signals are sent to a digital-to-analog converter (DAC), which is reduced to an analog waveform at the same sampling speed, amplified and sent to the speaker to emit sound, a technique known as Pulse Code Modulation (PCM).

Sound card (soundcard), also called audio card (Hong Kong and Taiwan called sound effect card), is the most basic component of the computer multi-** system, is a kind of hardware to realize the mutual conversion of sound wave digital signals.

The basic function of the sound card is to convert the original sound signal from the microphone, tape, and CD, and output it to the sound equipment such as headphones, speakers, amplifiers, and tape recorders, or to send out the sound of a synthesized instrument through the ** device digital interface (MIDI).

The world's first sound card is called Adlib Magic Sound Card, which was born in 1984 in the British company AdlibAudio. It can be said that Adlib is a veritable "father of sound cards". Of course, the technology at that time was still very backward, there were many deficiencies in performance, take this sound card as an example, it was mono, and the sound quality was simply rotten, but there is no doubt that its birth created a precedent for computer audio technology.

The main role of the sound card:

1. Digital sound files. Through the control of the sound card and the corresponding driver, the signal from the microphone, receiver recorder and other audio sources is collected, compressed and stored in the memory or hard disk of the computer system.

2. The digital sound file compressed by the laser disc is restored into a high-quality sound signal, which is amplified and released through the speaker.

3. Digitize the sound file to achieve a specific audio effect.

4. Volume, combine various sound sources to realize the function of reverberator.

5. Synthesis technology, reading text information through sound card. Such as reading English words and sentences, playing **, etc.

6. Audio recognition function, allowing the operator to command the computer with passwords.

7. Electronic musical instruments. In addition, with the help of the driver, the sound card can output files stored in MIDI format to the corresponding electronic musical instrument and produce the corresponding sound. Make electronic musical instruments under the command of sound cards.

Sound card, also known as audio card, is the most basic component of multi-technology and is a kind of hardware that realizes the mutual conversion of sound wave digital signals. Its basic function is to convert the original sound signal from microphones, tapes, and discs, and output them to earphones, speakers, amplifiers, tape recorders and other sound devices, or to make musical instruments sound beautiful through the digital interface of the equipment.

The connectors of the sound card generally have two types: socket and round jack, which are used to connect input and output signals. At the same time, all computers need to have a sound card, and the sound card is generally compatible, so there is no need to worry about configuration compatibility.

The above is an introduction to what a sound card is, I hope it can be helpful to you.

Prepare materials: sound card, screwdriver.

Specific steps: The first step: first shut down, disconnect the power supply, and face the front panel of the machine;

Step 2: Remove the screws by hand or with a screwdriver and open the left bezel;

Step 3: Find the PC slot (the two white ones are both PC slots) and remove the bezel behind the machine that is aligned with the PC slot.

Step 4: Align the gold finger of the sound card with the PC slot, insert the sound card in parallel and forcefully, fix it, remember: be sure to plug it in tightly, and tighten the screws at the panel. The sound card is installed.
