How to audition the sound effects 50 tips that novices must know about sound effects
In the process of sound installation, there are often difficulties After a long time, the sound effect is not very ideal, which makes people very depressed. How can I get the best sound effects? Below, I’ll give you some tips to make the sound even better.
1. RTFM is the abbreviation of “Read the Maruel”. Although it seems that all the steps from wiring to speaker placement can be done by yourself, unless you read the manual, your approach may reduce the performance of the sound, or even make it worse. bad equipment. Whether the manual is dry or glowing, it should be read first.
2. A suitable rack is necessary. One box per machine. The racks ensure that the machines are protected from vibration, and the distance between each machine is particularly good for heat dissipation.
3. If you have to stack the machines one by one, put the power amplifier on top, because the power amplifier generates the most heat and needs to be dissipated the most.
4. Consider that you may have to buy other equipment in the future. When buying a rack, you should buy one with more layers to avoid repeated investment.
5. If the rack has wheels, it is very convenient to clean the floor under the rack, but if the rack has feet, it can be fixed, and the sound effect will be better. Choosing the right rack, it is best to have both advantages.
6. Check whether the rack can bear weight, so that sand or special metal is added to increase the weight to prevent shocks, and sand is poured into the hollow structure of the rack (such as pillars) to prevent noise when the volume is loud.
7. Also pay attention to the choice of the rack, glass is very beautiful, but MDF is better, preferably with nails or damping glue, but if you use a glass rack and have children, you need to Fix it a little more firmly.
8. There are other ways to benefit your device. Placing the CD player on foot pegs (such as those produced by Audioquest), a special platform, or a board made of wood chips or even marble can help reduce vibration.
9. Turntables are more prone to vibration. If it’s a wood-floored room, and the floor also conducts vibrations, consider fixing the rack to the wall, especially if you wake up in the morning and want to listen to rock in the morning.
10. The speaker stand is also very particular. If it is a small hall, bookshelf speakers are generally used. The bracket is very important. You should buy the best shelf. The more stable and rigid the better.
11. The level of the feet should be adjusted well, and then fixed with a wrench (usually attached to the equipment). Be careful not to overtighten the screws. For some screws of poor quality, overtightening will cause slippage.
12. Some audio cables are directional, pay attention to the plug in the direction indicated by the arrow on the plug, for example: the signal of the CD player is input to the power amplifier, and the signal of the power amplifier is input to the speaker.
13. You can screw in the Phillips screw on the wooden floor first, and then insert the foot nail on the screw, pay attention to adjusting the level.
14. Many speakers, whether installed on the floor or on a shelf, benefit from a solid floor.
15. Whether the small speaker is mounted on the shelf with foot nails or damping glue, it is best to do it according to the manufacturer’s suggestion, but you can test it first.
16. If the speaker is to be mounted on a wall, the wall must be stable, and the tweeter should be positioned as high as your ears would normally be when listening.
17. Do not place potted plants, table lamps or porcelain figurines etc. on the speaker. Some of them may vibrate with the music and be distracting.
18. If the speakers are too close to the wall, the bass will be insufficient if indoors, and the bass will be too heavy if outdoors. In any case, don’t place the speakers in angled areas, which will muddy the bass.
19. A general rule is that speakers should not be farther apart than they are from the listener. However, most speakers require a distance of at least 1.5-2 meters to produce a good sound image position. If the distance is too far, a hollow effect will occur.
20. Adjust the orientation of the speakers until the sound image is three-dimensional. The vertical lines from the front panels of the two speakers should cross where you are listening.
21. Check that both speakers are tilted the same way, you should be able to see the same amount of surface area for the left and right speakers.
22. Power is important. The ideal is that each machine has its own separate socket, and it is not better to use a good quality extension board than to plug it into a wobbly three-pin socket.
23. Some people think that a special power cord for the hi-fi audio from the electric box will make the audio power supply purer than other machine power supplies. In fact, it is not. affect the power supply.
24. Connect the cable first and then turn it on, so as to prevent the “flashing” sound of the speaker. Note that before turning on the amplifier, turn the volume down to the minimum.
25. A “burn-in” before power on is necessary. It helps the components reach the operating point temperature and makes the mechanical parts operate flexibly. The power amplifier will not reach the top position until at least 24 hours after the power is turned on, and the CD should also be played repeatedly and randomly for about the same time.
26. The speakers also need to be “burned in”. Connect one side of the speakers to the front, and the other side reversely (the positive pole of the cable is connected to the negative pole of the speaker), and then put the two speakers face to face, and the sounds they emit will be canceled due to the reverse phase. In this way you can make the speakers reach their best condition faster.
27. Check the wiring on the back of the speakers after “burning in”, they may be loose due to the vibration of the speakers and “sizzle” with the music.
28. Do not power off when not in use. This makes it ready to use and never needs to be warmed up again. There is generally a “Standby (standby) button on the machine. Except for the tube amplifier, other machines only consume very little electricity in this state.
29. The function of the wire is also very important, do not use it casually. The cable that comes with the machine, some brand name machines have a really good cable, but only a few exceptions, most are of poor quality, ?500 or more systems come with ?40 cable , it can be said to be worth the money.
30. If the distance between the power amplifier and the audio source is less than 1 meter, try to buy a short cable, which not only saves money but also improves the sound quality. There is a 0.5-meter crossover cable for sale.
31. If it is connected by bi-wiring, use the exact same two pairs of cables or two pairs of specially allocated cables, 2 to 3 pounds / The meter is already very good. Some people think that using a thinner wire for the treble and a thicker wire for the bass will give better results, we think it is better to use the same wire.
32. If the speaker uses a spring clip For wiring, keep 10-15 cm of speaker wire, cut off the wire at the oxidized connector every 6 months, and re-stripping the wiring.
33. Two speakers, even if one Only 1 meter away from the power amplifier, and the other one is 5 meters away from the power amplifier, and the speaker cable should be the same length. The shorter the better, as the saying goes: “One more incense burner, one more ghost. “The shorter the cable, the less impact it has on the sound quality.
35. Few speakers come with speaker cables, it’s a good idea to buy 2-3 pounds per meter of cable, and retailers can also provide different colors Make sure the connection is correct.
36. If you need a long-distance cable, you should choose the special one.
37. If you use the feet to stand on the concrete floor , stand on the shelf to see if it is shaking, make sure it does not shake.
38. The signal cable is hidden behind the machine, so that the whole set of speakers looks neat and tidy. Separate the signal cable and the power cable to avoid Cause interference, if it cannot be separated, cross at right angles.
39. Some racks have special “cable channels” for fixing cables, but use the power cords attached to the machine. A soft cord is enough.
40. After the cord is connected, it is generally not necessary to maintain it, and it is enough to wipe off the dust at ordinary times. Just remove it.
41. Every few months, unplug all the cables and reconnect them again to clean the connector. If the connector is dirty, you can buy a special one Connector cleaner, be sure to unplug the power before doing all the above.
42. If you plan to have a party, it is best to hide all the machines first. Because some people have more hands and more Test the maximum volume of the sound on the floor, and someone will accidentally spill some wine in the amplifier, which will make you lose money.
43. You want to add other audio sources, but the input of the amplifier is not enough. What should I do? In fact, don’t look at the “CD, TAPE, TUNER” written on the back of the amplifier, except that the phono jack is dedicated, the other is the same line input, and can even accept the audio signal output by the computer.
44. If the power socket is not enough, many manufacturers such as QEDTANDY have extended power supplies to solve this problem.
45. The life of CD is longer than that of LP, but it should be stored carefully. After listening, put it back in the box, Don’t use it as a beverage tray, use a soft cloth to wipe the dust on the surface of the disc, wipe it in a radial direction, do not wipe it in a circle.
46. If you smoke or the surrounding environment is dusty, the laser head of the CD It will get dirty, clean it with a cleaning dish with a small brush, sometimes a special cleaning agent is dripped on the small brush, and some dishes even have a voice indicating the cleaning steps.
47. Almost All speakers will sound better after removing the dust cover. Some speakers have a metal cover to protect the tweeter. Use damping glue to remove the cover without damaging the cover.
48. There is a kind of “special green” “ink” (in a marker-like pen), applied to the edges of a CD disc, a method of reducing light scattering, or by holding the disc abruptly during operation to relax the tension created by the material on its surface during manufacture , try these if you hear anything Different, just right.
49. If a speaker doesn’t ring, it’s probably because the cable is loose. Try swapping the two channels, or try connecting another cable. If you call a professional to repair it, the cost is very high, so you can solve it yourself.
50. Still have ?200 to spend on improving the equipment, don’t know how to spend it? Here’s a global answer – buy a disc and enjoy it yourself.
