1. First, take out the prepared computer stereo and observe the interface of the stereo. General stereos have round head interfaces and USB interfaces. Then turn the back of the computer host over and take out the audio interface to compare the interface style of the host. Then plug the round head connector of the stereo into the audio connector of the computer.
2. First, you need to find the "PDIF" output jack on the TV. Next, please prepare a "coaxial line" (coaxial line is usually yellow). Then, connect the coaxial end and the other end of the S/PDIF jack of the TV to the coaxial input jack of the converter.
3. Installation steps to determine the position of the speaker A. If the home 1 system is used, it can be divided into left and right main speakers, center speakers, left and right surround speakers and subwoofer. First, reshape the four wires of the two speakers, peel off the ends of the wires by one centimeter and cut them with scissors. Connect the black lines of two lines marked with L or lines marked with negative sign in the speaker to the terminals marked with negative sign on the left side of the four terminals of the power amplifier.
Find four power lines (positive electrode+positive electrode) respectively, and the other four are grounding lines (negative electrode). Touch four sets of horn wires with one foot of the horn and the other foot of the horn. Four groups of speakers must be connected in a unified way: the plug with red dot or red line is the power cord.
Two trebles and two bass are combined into two groups by frequency divider, and then connected to two channels and power amplifier. Four speakers can be paired in parallel (if more than 8) or in series (if less than 4) and then connected to the power amplifier.
The four terminals and two terminals of a loudspeaker are connected in the same way, and four-terminal loudspeakers are generally equipped with two short-circuit rings.
One: three pins: 1, unplug the non-grounding wire from the horn and connect it to the terminal marked "button" of the relay, and the horn grounding wire will not move. 2. Connect the terminal marked "Battery" of the relay to the positive pole of the battery with wires. 3. Connect the terminal marked "Horn" of the relay to another terminal on the horn with a wire.
In the two frequency dividers inside the sound box, four capacitors are welded in parallel, and then four tweeters are connected respectively. As shown in the figure, the capacitance of C 1~C4 in the figure is 1 ~ 10 microfarads. The larger the capacity, the louder the sound, which can be adjusted according to your own preferences.
How to replace K-song speakers for home floor speakers
The horn is installed from the inside. You need to open the back panel to replace the speaker.
First, determine the caliber of the original speaker and buy the original size. Second, be sure to see clearly the endurance and impedance of the original speaker, and make no mistake. If it is an ordinary speaker, you can buy an ordinary speaker. If you want something better, you can buy a hivi kit. If there is a frequency divider in the speaker, it must be welded correctly.
If you want to match a speaker, just match it according to the size and power of the original speaker. But the effect will not be very good.
It can be completely replaced, and the following points should be paid attention to when replacing: First, the installation hole of the replaced full-range speaker is the same as that of the original speaker. Second, after the change, the wiring cannot be connected to the original speaker, and there is no need to change the frequency divider. Just connect the newly replaced full-range speaker directly to the input point of the speaker without going through the frequency divider.
Speaker power should match the power amplifier. I suggest you change it to 4 euros with the same caliber. As for power, there are many ways to mark it. The sinusoidal power of 6W may be greater than the peak power of 20W. I don't know what your standard is, so I can't talk nonsense. I suggest you have a look at your amplifier and see what the output power is. Just change it to something similar.
How to place the home audio equipment?
The "regular triangle method" can reduce the excessive interference of the reflected sound from the surrounding walls on the speaker direct sound, and can obtain a good sense of positioning and a wide and deep sound field. Therefore, the "regular triangle method" is the most direct and clear arrangement of details.
The listener should sit between the two speakers, and the distance from the speakers should be slightly greater than the distance between the two speakers. Set the distance between the two speakers, and then the distance between the wide sound stage and the clear center audio and video, and finally determine it through repeated audio-visual communication.
Granite or granite, especially granite, has the highest density and is an ideal load-bearing equipment, but its thickness is more than 3 cm. The placement of sound should be adapted to local conditions. Some people moved the position of sound to furniture, because there were other furniture in the room first.
How to place the home audio correctly? PChouse, let's take a look. In-axis method: first place the speaker between one-third and one-half of the length of the room, and then put the speaker as close as possible to the side wall. If the room is too wide, there is no need to be near the side wall.
The rear left and right surround sound should be placed on the back walls on both sides. If possible, frame the surround speakers with an audio tripod, which should be as high as the left and right main speakers. The layout is also in the form of an isosceles triangle, and the distance from the bottom to the main sound box is equal to or slightly longer.
