The dynamic range of a microphone is the difference in SPL between the noise floor and the maximum SPL. If stated on its own, for example, "120dB", it conveys significantly less information than having the self-noise and maximum SPL figures individually. With low self-noise, moderate sensitivity, and high SPL handling, the CMIT 5 delivers sonic performance deserving of premium mic preamps. 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. David Edward Hughes: Concertinist and Inventor" (PDF).

The RØDE VideoMic Pro+ is a great choice for mobile journalists, vloggers, and budget filmmakers that are in the market for a flexible camera-mount shotgun mic that’s also good on a boom.

The MKE 600 features a lightweight and durable metal housing that provides reliable toughness without adding too much weight to your rig.You might assume the actual capsule of the mic (the part that translates the sound to an electrical signal) is located at the end of the microphone but in fact, it’s actually found about halfway down the tube. Why is it so long? Why are there so many lengths available? When do you need a shotgun mic? Which length is right for you? This post will answer all of those questions. This makes the MKE 600 much more efficient at capturing distant sources than the omnidirectional mics found in most cameras.

The frequency response of a microphone is important because it affects the sound of the recording. A microphone with a flat frequency response reproduce all frequencies equally well. This produces a natural sound. In contrast, a microphone with a shaped frequency response will boost or attenuate certain frequencies. This can be better for specific situations. Harry F. Olson and Les Anderson, RCA Model 44 Ribbon Microphone". Mix Magazine. September 1, 2006. Archived from the original on March 24, 2008 . Retrieved April 10, 2013. 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.

The Rode VideoMic Pro is the best bang-for-your-buck shotgun microphone

Knowles Completes Acquisition of NXP's Sound Solutions Business". Knowles . Retrieved July 5, 2011. This shotgun microphone features a hyper-cardioid polar pattern at low to midrange frequencies and transitions to a lobar pattern in high frequencies, enabling it to attenuate 125 Hz to 2 kHz by approximately 10 dB at the 90° off-axis points. This is great for recording dialogue, foley, and other sounds with full dynamics and clarity. In 1916, E.C. Wente of Western Electric developed the next breakthrough with the first condenser microphone. [14] In 1923, the first practical moving coil microphone was built. The Marconi-Sykes magnetophone, developed by Captain H. J. Round, became the standard for BBC studios in London. [15] [16] This was improved in 1930 by Alan Blumlein and Herbert Holman who released the HB1A and was the best standard of the day. [12] However, this is actually a pretty crude solution because the actual amount of cancellation depends on the wavelength of the sound, its angle of incidence, the length of the tube, and the slot spacing. Most standard-length shotgun tubes don't have much effect below about 2kHz, and are no more directional than the basic supercardioid capsule design they employ below that frequency. While very long rifle mics do exist and are directional to lower frequencies, (for example, the Sennheiser MKH816), they are unwieldy to use and the longer tube necessarily moves the capsule even further away from the sound source, negating to some extent the enhanced directional benefits.

The Schoeps CMIT 5 features three selectable filters that allow you to manage boom noise, proximity effect, and high-frequency emphasis to ensure balanced, professional audio quality. It features reliable operation and low susceptibility to hum, GSM, and radio-frequency interference. The engineers at Shure did a fantastic job on the VP89M, adding a phantom-powered preamp that features a switchable low-cut filter to attenuate problematic bass frequencies such as rumble. Have you ever seen the mic operator on a film shoot? They are usually stood behind the camera holding an extremely long mic stand above their head while pointing it at the voice talent. cumbersomeness of having to have a microphone on him. So a shotgun microphone is advantageous in any situations where distance Estreich, Bob. "David Edward Hughes". Archived from the original on November 1, 2019 . Retrieved December 30, 2013.If you've looked at shotgun mic specifications, you've likely seen microphones specified as "supercardioid/lobar" or "hypercardioid/lobar." Understanding those terms requires knowing a little bit more about how a shotgun microphone gets its characteristic directionality. This is the result of an interference tube, which is mounted to the front of the microphone capsule (typically a condenser). It has several openings along its length, which are designed to allow sound to enter the tube. Common uses of shotgun microphones are for talks or speeches in meetings, conferences, and lectures.

Therefore, shotgun microphones are highly used in applications where only the sound directly in front of the microphone is to Of course, if it’s an actor you are recording then a lavalier mic probably isn’t the best solution (imagine recording a drama set in the 1920s and the main character has a modern mic attached. It won’t look very good!).
