What to pay attention to when using professional audio equipment.Bar speakers Vendor

　　1. Put the device in the cabinet. Some people put the components in a custom-made cabinet for decoration and maintenance. This will make the tone muddy due to the latent vibration caused by the space in the cabinet. The power amplifier and other components are prone to overheating and aging due to insufficient circulating air. If the speaker is installed on the wall, the sound effect will become blunt.

　　2. Stacking devices. Many people like to place video disc players, amplifiers, tuners, digital-to-analog converters and other machines on top of each other, which will cause mutual interference, especially radium camcorders and power amplifiers, which will cause the sound to become harder and depressive. The correct way is to put the device on the professional audio rack planned by the factory.

　　3. The power plug is irrelevant. A good system for the positive and negative processing of the power plug has a clear tone and naturally smooth; the positive and negative are inconsistent or uneven, and the tone will be hard and rough.

　　Fourth, the wiring is not firm and unclean. If the sound of the system is dry and hard, one of the reasons may be poor contact, such as a weak plug, oxidation of the contact surface, dust or oil stains, etc., so you should always check and keep the contact surface clean.

　　5. Use marble or glass to carry the device. The low density of marble and high resonance will affect the function of professional audio. The density of glass is higher than that of marble, but it is not thick and the resonance is more severe. Granite or granite can be used, especially granite, which has the highest density and the load-bearing device is more ideal, but the thickness should be more than 3 cm.

　　Sixth, the placement of speakers is "adapted to local conditions." Some people have other furniture in the room, so they put the speakers in place to tolerate the furniture. The correct one is to determine the listening interval first, and then place the speakers at 1/3 between the seat and the opposite wall. The interval between the speakers is 0.7 times the direct distance between the listener and the speakers, and the height should be equal to the listener’s ears and the tweeter. .
