RODE NTG2 SHORT SHOTGUN MICROPHONE

Product Information

USB allows direct connection to PCs. Electronics in these microphones powered over the USB connection performs preamplification and ADC before the digital audio data is transferred via the USB interface. RF condenser microphones use a comparatively low RF voltage, generated by a low-noise oscillator. The signal from the oscillator may either be amplitude modulated by the capacitance changes produced by the sound waves moving the capsule diaphragm, or the capsule may be part of a resonant circuit that modulates the frequency of the oscillator signal. Demodulation yields a low-noise audio frequency signal with a very low source impedance. The absence of a high bias voltage permits the use of a diaphragm with looser tension, which may be used to achieve wider frequency response due to higher compliance. The RF biasing process results in a lower electrical impedance capsule, a useful by-product of which is that RF condenser microphones can be operated in damp weather conditions that could create problems in DC-biased microphones with contaminated insulating surfaces. The Sennheiser "MKH" series of microphones use the RF biasing technique. A covert, remotely energised application of the same physical principle was devised by Soviet Russian inventor Leon Theremin and used to bug the US Ambassador's Residence in Moscow between 1945 and 1952.

During operation, light from a laser source travels through an optical fiber to illuminate the surface of a reflective diaphragm. Sound vibrations of the diaphragm modulate the intensity of light reflecting off the diaphragm in a specific direction. The modulated light is then transmitted over a second optical fiber to a photodetector, which transforms the intensity-modulated light into analog or digital audio for transmission or recording. Fiber-optic microphones possess high dynamic and frequency range, similar to the best high fidelity conventional microphones. Plenty of times, you’re on the street or live streaming and don’t have the luxury of individually miking people, or you’re filming a scene where you can’t have a visible lavalier mic. That’s why you’ll find top-notch shotgun mics throughout the professional world—often accompanied by professional-level prices. But shotguns have been around for a while, and these ubiquitous tools of the trade are often inexpensive enough that even beginners and budget-minded users can add quality equipment to their kit bags.

However, Schoeps mics are some of the most sensitive to environmental issues like humidity. You don’t want to bring the CMIT 5 into the jungle or shoot down in Florida outside of an environmentally controlled building. This microphone is for the studio, concert hall, or closed set.The Audio-Technica AT8035 is a long shotgun microphone, measuring over 14.5 inches (369 mm) in length. In simple terms, the extra length of the interference tube means that the AT8035 will reject more off-axis sounds and be more directionally focused. You can also get good audio when further from your subject with a long shotgun microphone than one with a shorter tube. Shotgun mics have surged in recent years, thanks to the boom in independent productions and affordable technology in the fields of music, film, and broadcasting. A little bulkier and heavier than the Rode VideoMic Go is Rode's VideoMic Pro. This hotshoe shotgun mic shares a similar size and design, but adds extra features for those seeking more flexibility and higher quality recordings. Frequency response for mics is the range of frequencies that a microphone can reproduce accurately. In other words, determines how much sound a mic can capture, from low to high pitches.

But thanks to its wide, natural 40-20,000 Hz frequency response and excellent build quality, it’s also the last stop for many pro and semi-pro indie filmmakers, documentarians, broadcast journalists, podcasters, and in-house audio-video teams. a b Benesty, Jacob; Jingdong, Chen (October 23, 2012).

A hyper-cardioid microphone is similar to cardioid, but with a slightly larger figure-8 contribution, leading to a tighter area of front sensitivity and a smaller lobe of rear sensitivity. It is produced by combining the two components in a 3:1 ratio, producing nulls at 109.5°. This ratio maximizes the directivity factor (or directivity index). [50] [51] a b Robjohns, Hugh (2001).

Because of differences in their construction, microphones have their own characteristic responses to sound. This difference in response produces non-uniform phase and frequency responses. Additionally, microphones are not uniformly sensitive to sound pressure and can accept differing levels without distorting. Although for scientific applications microphones with a more uniform response are desirable, this is often not the case for music recording, as the non-uniform response of a microphone can produce a desirable coloration of the sound. There is an international standard for microphone specifications, [62] but few manufacturers adhere to it. As a result, comparison of published data from different manufacturers is difficult because different measurement techniques are used. Caution should be used in drawing any solid conclusions from this or any other published data, however, unless it is known that the manufacturer has supplied specifications in accordance with IEC60268-4. However, if you aren’t familiar with shotgun specifics, it is better to follow our guide, which narrows it down further: Some microphones are intended for testing speakers, measuring noise levels and otherwise quantifying an acoustic experience. These are calibrated transducers and are usually supplied with a calibration certificate that states absolute sensitivity against frequency. The quality of measurement microphones is often referred to using the designations "Class 1," "Type 2," etc., which are references not to microphone specifications but to sound level meters. [63] A more comprehensive standard [64] for the description of measurement microphone performance was recently adopted. Various standard techniques are used with microphones used in sound reinforcement at live performances, or for recording in a studio or on a motion picture set. By suitable arrangement of one or more microphones, desirable features of the sound to be collected can be kept, while rejecting unwanted sounds.
