In simplest terms, if a sine wave is injected into a system at a given frequency, a linear system will respond at that … A good headphone has a neutral frequency response and reproduces the audio content (music), as it was intended by the producer/engineer. The frequency response function amplitude versus frequency of the SDOF can be obtained from executing the programming codes as shown in Figs. The mic incorporates three switchable filters: An internal blast filter reduces popping, breath sounds and excessive sibilance. Can't find what you're looking for? Its Variable-D design and heavy-duty internal pop filter excel for close-in voice work, while an internal element shock-mount reduces vibration-induced noise. According to E-V, this allows the mic to “maintain [a] uniform low-frequency response at any distance,” making it more forgiving for sources that move around the element. Frequency Response: 20-20kHz ±3dB = Good. Professional Loudspeakers & Mics - Electro-Voice. In other words, an ideal frequency response is one that doesn’t adjust the volume of the bass, middle, or treble, from our source. Post by _Wim_ » Tue Mar 05, 2019 7:56 pm. The RE320 & RE20 have a single high pass (low cut) switch, while the RE27 N/D has 3 switches, (2) high pass switches, and (1) high cut switch. According to E-V, this allows the mic to “maintain [a] uniform low-frequency response at any distance,” making it more forgiving for sources that move … Nicely done. Superb resolution and depth for voice and instruments have also made the versatile RE27N/D a revered workhorse tool with recording studios and live sound engineers for a wide variety of production situations. Contact us! The RE320 has a minor bass boost of 1dB between 150 & 250 Hz, and then has a relatively flat mids section. Two easily operated bass roll-off switches, offering a sharp low-frequency cut at 200 Hz or a gentle roll-off, are avail­able for special situations where bass attenuation is required. Since we're only concerned with time values for finding the phase shift, the data doesn't need to be normalized. Meaningful information. It is a large dynamic microphone intended for use on broadcast vocals as well as instrument applications. This graph is known as the “Frequency Response Graph.”(Clever, no?) Electro-Voice RE27N/D Frequency Chart: Cardioid. The RE27N/D uses rare-earth Neodymium magnets for enhanced detail and high-frequency response, as well as increased sensitivity. RE: In what way are the measurements for frequency response and distortion helpful? I have an average voice and it sounds spectacular on this mic. INNOVATION HAPPENS HEREElectro-voice is part of the Bosch Communications Systems family of brands, offering the world’s most complete portfolio of professional audio and communications solutions. posted by ppopp on August 28, 2020 at 16:14:32: Please let us know! Hi Kai, First of all many thanks for the very detailed reply (twice!). Re: Frequency Response Analyzer with Bode Plots. Process Control: Modeling, Design, and Simulation. The RE20 dynamic cardioid microphone is truly an industry standard, a firm favorite for broadcasting, podcasting, and sound engineering worldwide. Did we get anything wrong on this page? Now it’s time for another hard part: Frequency responses are almost always shown as a graph. Upper Saddle River, N.J. Prentice Hall, PTR 2003. Posted by John Elison on August 29, 2020 at 07:49:27 . The RE27N/D is a modern reinterpretation of the RE20. It is a measure of magnitude and phase of the output as a function of frequency, in comparison to the input. Click the 'X' at the top right corner to dismiss this window! EECS 105 Spring 2004, Lecture 27 Prof. J. S. Smith Frequency response zSo far, we have modeled the small signal response of the stages for low frequencies (but not so low that we couldn’t neglect the DC blocking coupling capacitors!) Frequency response is the most important part of an audio reproduction, and for the most part, the perceived subjective sound quality of a speaker can be predicted from its frequency response 1,2,3,4. A cookie that stores your current privacy settings is also set (selection cookie). Both the RE27N/D and NE20 use Electro-Voice’s Variable-D technique to reduce proximity effect. Superb resolution and depth for voice and instruments have also made the versatile RE27N/D a revered workhorse tool with recording studios and live sound engineers for a wide variety of production situations. technically non-essential cookies and tracking mechanisms, that enable us to provide you with customized offers (marketing cookies and tracking mechanisms), The RE27N/D is a modern reinterpretation of the RE20. With the exception of the selection cookie, 1.2–1.4 where a sine wave signal of fixed excitation amplitude is used as input, the excitation frequency of the sine wave signal changes from the low to high to cover the resonant frequency. High-frequency shelf EQ: -3dB above 3kHz. A switch on the mic body provides a high-pass filter, aka a “bass tilt-down switch,” which drops the low-frequency response by approximately 2.25dB/octave below 400Hz. Description of Amplitude Ratio, Phase Shift and Frequency Response.
