Evaluate the performance of a microphone, frequency response characteristics, directionality and sensitivity is very important. We'll see GL-400 frequency response curve and point to type figure.
Human can feel the frequency of the voice of the maximum range is 20 Hz-20 kHz. Therefore, an ideal receiver should be able to 20 Hz-20 kHz within the scope of the voice to make the response.
GL-400 frequency response wide, distortion, dynamic range, GL-400 frequency response: 20 Hz-20 kHz, covering the entire band sound becomes to notice the distinctness. The frequency response curve known GL-400 in the range of frequencies of sound to relatively uniform response, although the ideal frequency response curve should be like desktop-sample flat, but by physical structure of the limit, the receiver of the response range of frequencies of the uniformity of the voice response is very difficult, so can say GL-400 frequency response curve is perfect, GL-400 pickup performance will be perfect.
Different recording environment need a microphone directionality and sensitivity is different, such as single people and equipment in a single point to the need to double the tape, radio interview can be used to double, environment and collective recording with the whole point to; Distance audio source high sensitivity to guarantee to pick up an audio source, close audio source available low sensitivity sound pickup and reduces environmental noise. GL-400 can meet all kinds of needs. GL-400 sensitivity:-33 /-39 /-38 dB ± 3 dB (0 dB = 1 V/Pa at 1 kHz) corresponding to the point/heart-shaped/double pointing, plus 10 dB attenuation set sensitivity-switch, in view of the different professional recording occasions need to design, sound pickup more accurate and better effects.
You can see from the graph 110 Hz frequency attenuation and not be effective decay of the two curve, because GL-400 set low frequency attenuation switch, and open to the low frequency attenuation switch after the microphone can effectively filter out the outside noise, vibration, low frequency noise wind, in more noisy bad border to pick up effective pure quality. In the environment is not the low frequency noise environment, can be closed low frequency attenuation switch.
Most worth GL-400 pride or Ø 34 mm latest r&d double-sided gold-plated side the lead after film sound using technology head, in the technology under the moist, completely overcome the shortcomings of the traditional voice microphone nausea, we hear is a fully empty spirit, keep the covent garden, have warm feeling, full of vitality studio level quality effect.
The built-in transistor circuit noise, the noise is small, stable performance and can withstand non-linearity, the most loudly level: 130 dB (THD than 1% at 1 kHz), namely the microphone to admit the highest stability of 130 dB (a voice, and basically all voices and instruments can produce sounds are less than 130 dB (take-off of voice also is 120 decibels), GL-400 equivalent noise levels: 12 dBA microphone itself than that noise circuit to work less than 12 decibels, is not 'perception of the audio section, ensure quality pure, make up the microphone voice more fruity and full, full of vitality
Nets mask use double deck high purity brazing toughened WangTou, outer layer is the thick metal nets, inner lining for thin metal nets, inside and outside laminated and can form a only allow sound waves enter airtight metal space, shielding electromagnetic interference, sound membrane charge from the outside electromagnetic waves interference, pick up sound signal effectively.
Ontology high strength zinc alloy, firm structure, fight broke the gender is good, even if accidental throw, and will not affect sound pickup and microphone head. The paint anticorrosion technology, durable; Ontology surface grinding and anti-wear coating process, is not easy to have Nick; The general appearance of the beautiful blue collocation lubricious gauze nickel, classic refined, beautiful atmosphere, super simple sense, full of modern beauty.
The microphone the tail is plated with gold standard XLR three needle corleone plug, gold conductivity is good, not easy oxidation, moistureproof, ensure plug performance is good, is not easy to corrosion, and to GL-400 added a honour; The microphone by standard thread, can be fixed in a standard thread interface shock on the shelf. GL-400 output impedance low, make the phone and not under the long-distance transmission of electromagnetic field effect, ensure transmission audio signal pure.
GL-400 standard configuration for: high-grade aluminium alloy suitcase, portable bag, specification, ZhiBaoShu, high-grade shock mounts, GL-400 each a microphone.
For GL-400 mainly aimed at the professional recording group engaged in need, such consumers most of 48 V illusion power equipment and wire. In line with the principle of shoes for the consumer, the power source and the illusion wire GL-400 options, has the power source and the illusion of wire friends don't have to buy again, can reduce the cost of buying, Of course friends in need can be selected power and wire victory illusion, winning six models illusion power and all sorts of length to choose to buy corleone line, very human parts the configuration of the processing.
Equipped with a former black high-grade shock mounts, the seamless welding technology, firm structure, beautiful and easy, by high performance elastic leash, flexibility is good strong vibration resistance, Shock mounts the surface of electrophoresis technology processing, prevent oxidation rust. Shock mounts built-in standard conversion nut, can apply to the desktop, hanging, LiDeShi all stents.
Configuration portable bag, in a microphone when not in use, with transparent bag wrapped up the PO them into portable bag can rise to moisture, prevent dirt; Portable bag have lift justice, easy to carry the microphone.
Configuration exquisite portable aluminum alloy boxes.
