RODE NTG2 SHORT SHOTGUN MICROPHONE

Product Information

There are two main categories of condenser microphones, depending on the method of extracting the audio signal from the transducer: DC-biased microphones, and radio frequency (RF) or high frequency (HF) condenser microphones. To get the best sound quality using your shotgun microphone, you need to understand the basics of how it works. What is a shotgun microphone? Shotgun principle — showing how off-axis sound arrives at the capsule diaphragm via different path lengths, and thus different phases. The 'industry standard' MKH416 shotgun mic. Physically longer designs such as this may seem unwieldy but their frequency response extends lower than shorter models. SOS Technical Editor Hugh Robjohns replies: Shotgun or rifle mics are more properly called 'Interference Tube' microphones, and they are often assumed to have magically tight polar patterns that simply don't exist in reality. Shotgun mics do have their uses, of course, but have to be used intelligently to avoid the significant compromises associated with them. 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.

The 10″ long MKE 600 uses an interference tube and a super-cardioid/lobar polar pattern to provide noticeable directivity on-axis along with significant attenuation of sound entering at the sides and rear. The wavelength of sound at 10kHz is 1.4" (3.5cm). The smallest measuring microphones are often 1/4" (6mm) in diameter, which practically eliminates directionality even up to the highest frequencies. Omnidirectional microphones, unlike cardioids, do not employ resonant cavities as delays, and so can be considered the "purest" microphones in terms of low coloration; they add very little to the original sound. Being pressure-sensitive they can also have a very flat low-frequency response down to 20Hz or below. Pressure-sensitive microphones also respond much less to wind noise and plosives than directional (velocity sensitive) microphones.

Additionally, shotgun mics aren’t the best choice for small rooms, especially those with lots of hard surfaces. They are more ideal for outdoors and large spaces with balanced acoustics. Should you buy? When paired with devices that don’t feature phantom power, the MKE 600 can be powered for up to 150 hours by a single AA battery, with approximately 8 hours of operation from the point when the low-battery indicator lights up red.

The additional length of the Audio-Technica AT8035 can make it unsuitable for on-camera use, as it will get in a shot with some lenses. Longer shotgun microphones are also more susceptible to the distortion of off-axis sounds that can occur in rooms with a lot of reverb.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.

Cardioid, hypercardioid, supercardioid, subcardioid [ edit ] University Sound US664A dynamic supercardioid microphone The Azden SMX-30V attaches to your camera with a standard cold shoe or via a 1/4-20 thread. In addition, the microphone will run for up to 100 hours on a pair of AA batteries and has an auto power on/off option to conserve battery life. The audio output cable is detachable, which means you can simply replace it if it breaks rather than needing to send it out for repairs.

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. The Joby Wavo is an inexpensive microphone, but it’s certainly an improvement on the microphone built-in to your camera or smartphone.

Yes, you can use a shotgun mic to record music. A good quality shotgun has a flat frequency response and directionality, making it very effective at capturing warm and subtle tones. Final thoughts on the best shotgun mics The main alternative to impedance bridging is impedance matching which maximizes power transfer for a given source impedance. However, this has not been relevant since the early 20th century when amplifiers were very expensive and produced a lot of heat. To reduce the number of amplifiers in telephone lines, power loss needed to be minimal so source and load impedances were matched. A downside to impedance matching is the 6dB loss in signal that occurs as only half the voltage level appears at the pre-amplifier's input. [59] Certain ribbon and dynamic microphones however are exceptions, due to the designers' assumption of a certain load impedance being part of the internal electro-acoustical damping circuit of the microphone.

In this way, these mics can pinpoint the source of sound while rejecting other noise. Some fans of shotguns have come to refer to them as ‘sniper mics’ because, when it comes to accuracy, there’s no substitute.
