Condenser microphone maintenance skills and advantages
Condenser microphone maintenance skills
Moisture-proof
If your area may have high seasonal humidity, try to find a closed condenser microphone if you open it.-style boxes, such as custom-made small shockproof boxes.,inside again.putonesome moisture beads, if the desiccant is wetDescriptionit is too wet, open the microphonecover, check the metal inner wall for moisture. If the metal inner wall of the microphone is wet, blow it dry with a hair dryer and then connect it to the device for 10 minutes before testing..use the microphone,recommend the use of the main table,Avoid holding hands for a long timethe wheat,produces sweat, which affects the microphone.
Rain-proof and dust-proof
Rain is the natural enemy of condenser microphone. The diaphragm of condenser microphone will accelerate the corrosion of metal materials due to water, and will cause short circuit of internal circuit wires. Don't put it in a box in a hurry after the end. Use a blower to dry it before putting it in.
Anti-fall
Special attention should be paid not to trip over the microphone holder when the wire is pulled, as the impact may cause the sensitivity of the condenser microphone to be reduced or even damaged.
Preheating
For many vacuum tube microphones, a period of warm-up is required before optimum operating conditions are achieved.
recommended to warm up the microphone from 2, 3 minutes to 15 minutes, so that after turning on the microphone, keep it in a working state until the recording is over.
Pay attention to the use of Cannon plug
The correct use of the Cannon plug, sometimes temporarily add or replace the microphone, pick up the head of the Cannon jerk and plug, easy to twist or break the three male feet.
Avoid hot-plug operations
Market are powered by phantom power supply, that is, most of the power supply is realized by connecting the microphone cable to the mixer. Therefore, you should try to avoid hot-swapping the microphone. Frequent large voltage fluctuations will greatly reduce the service life of the microphone. So try to connect the microphone to the mixer before starting a channel, and then turn on the power. If your vacuum tube microphone can be connected directly to the power supply, it is equally important to avoid hot plugging. Do not turn on the power switch of the microphone until you connect it to the mixer.
Condenser microphone
Converts sound directly into electrical signals
Condenser microphone is designed by using the principle of capacitive charging and discharging between conductors, using ultra-thin metal or gold-plated plastic film as the vibration film to induce sound pressure, so as to change the electrostatic voltage between conductors and directly convert it into electrical energy signals, and obtain practical output impedance and sensitivity through electronic circuit coupling.
Can show the characteristics of the original sound reproduction
Sound experts to the pursuit of "original sound reproduction" for the highest level of sound!from the analysis of the basic design principle of the microphone, it is not difficult to find that the condenser microphone not only relies on the precision mechanism manufacturing technology, but also combines the complex electronic circuit, which can directly convert the sound into electrical energy signal, which has extremely superior characteristics in nature, so it has become the best choice for those who pursue the "original sound reproduction.
Has an extremely broad frequency response
Diaphragm is the main component of the microphone that senses sound and converts it into electrical energy signals.diaphragmdesign, is to determine the microphone sound quality.duecondenser microphone can be made of extremely thin and light materials, and the induced sound pressure is directly converted into audio signals, so the frequency response bass can beextends to 10Hzbelow the ultra-low frequency, treble can easilyto reach10KHz ultrasound, show verywidewide frequency response characteristics.
With ultra-high sensitivity
Diaphragm, it can be extremely thin and light design,so not only the frequency response is extremely superior, and hasexcellent sensitivity, yes.senses extremely weak sound waves and outputs the clearest, most delicate and precise original sound.
Fast transient response characteristics
diaphragm, the ability to respond quickly to sound waves, the so-called "instantaneous response" characteristics, is one of the most important factors affecting the tone of the microphone. Microphonethe speed of transient response characteristicsdecisionthe weight of the whole diaphragm, the lighter the diaphragm, the responsespeed. Capacitive sound head extremely thin diaphragm, with very fast instantaneous response characteristics, can show clear, bright and strong timbre and accurate audio and video. In particular, the middle and bass are completely free of tone dye.and box, Trebledelicate and crisp, is the most significant characteristics of capacitive tone.
Has the characteristics of ultra-low touch noise
The touch noise generated by the contact with the palm when using the hand-held microphone, the original sound is mixed with additional noise, which has a great impact on the sound quality, especially for wireless microphones with preamplifier circuits, so the touch noise becomes an important item for judging the merits of the microphone. From the physical phenomenon, goose feather and copper plate also fell to the floor, goose feather can hardly hear the sound of falling, while copper plate is very loud, showing that lighter materials are smaller than heavier impact sound. Similarly, the diaphragm of the condenser microphone is relatively light, and it has the excellent feature of "ultra-low touch noise.
Has the characteristics of resistance to fall and impact
The use of the microphone is inevitable due to inadvertent drop collision caused by malfunction or abnormal. Since the capacitive sound head is composed of lighter plastic parts and a strong light metal shell, the impact force of falling to the ground is small, and the failure rate of damage is low.
Small size and light weight
Condenser microphone has the characteristics of small size, light weight, high sensitivity and superior frequency response due to its ultra-thin diaphragm,
Best fit on wireless microphones
Condenser microphone has the above excellent characteristics and has become the favorite of sound engineering experts and singing. However, wireless microphone singing on the stage or singing karaoke at home has become the trend in today's world. Wireless microphone has all the advantages of condenser microphone because it can provide the bias voltage required by condenser sound head. It has become the best microphone that professional sound experts dream of in the digital sound era.
