RODE NTG2 SHORT SHOTGUN MICROPHONE

Product Information

The mic can be tuned to handle different recording environments, with buttons providing low-cut filters at 75 Hz or 150 Hz. You can also boost the frequency at 7 kHz if things start sounding a bit muddy. The mic has adjustable gain, as well, to help compensate for very loud or soft sounds.

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. a b Benesty, Jacob; Jingdong, Chen (October 23, 2012).

Since all wind noise is generated at the first surface the air hits, the greater the spacing between the shield periphery and microphone capsule, the greater the noise attenuation. For an approximately spherical shield, attenuation increases by (approximately) the cube of that distance. Thus larger shields are always much more efficient than smaller ones. [ citation needed] With full basket windshields there is an additional pressure chamber effect, first explained by Joerg Wuttke, [65] which, for two-port (pressure gradient) microphones, allows the shield/microphone combination to act as a high-pass acoustic filter.

With a DC-biased condenser microphone, the plates are biased with a fixed charge ( Q). The voltage maintained across the capacitor plates changes with the vibrations in the air, according to the capacitance equation (C = Q⁄ V), where Q = charge in coulombs, C = capacitance in farads and V = potential difference in volts. A nearly constant charge is maintained on the capacitor. As the capacitance changes, the charge across the capacitor does change very slightly, but at audible frequencies it is sensibly constant. The capacitance of the capsule (around 5 to 100 pF) and the value of the bias resistor (100 MΩ to tens of GΩ) form a filter that is high-pass for the audio signal, and low-pass for the bias voltage. Note that the time constant of an RC circuit equals the product of the resistance and capacitance. Paritsky, Alexander; Kots, A. (1997). Shladov, Itzhak; Rotman, Stanley R (eds.).

This Joby microphone offers Active Noise Reduction which reduces handling and wind noise to a degree but is no real substitute for using a tripod and wind jammer. The Neumann KMR 81 i is compact and light enough to be used on a camera for handheld shooting. Though the mic is specifically designed for film and TV applications, it also works well for recording individual musicians, orchestras, and more. The limited off-axis coloration keeps the sound consistent even if the subject is moving around.Measurement microphones are generally scalar sensors of pressure; they exhibit an omnidirectional response, limited only by the scattering profile of their physical dimensions. Sound intensity or sound power measurements require pressure-gradient measurements, which are typically made using arrays of at least two microphones, or with hot-wire anemometers.

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.a b c "Should I Match Impedances of My Microphone to My Mixer?".

Condenser microphones require a power source, provided either via microphone inputs on equipment as phantom power or from a small battery. Power is necessary for establishing the capacitor plate voltage and is also needed to power the microphone electronics (impedance conversion in the case of electret and DC-polarized microphones, demodulation or detection in the case of RF/HF microphones). Condenser microphones are also available with two diaphragms that can be electrically connected to provide a range of polar patterns (see below), such as cardioid, omnidirectional, and figure-eight. It is also possible to vary the pattern continuously with some microphones, for example, the Røde NT2000 or CAD M179. AKG D 112 – Large-diaphragm dynamic microphone for bass instruments". AKG.com.
