sE4400a Large Diaphragm Multi Pattern Condenser Microphone

Product Information

Annealing— Grade 440 stainless steels are full annealed at 850 to 900°C, followed by slow furnace-cooling at about 600°C and air-cooling. Sub-critical annealing is carried out at 735 to 785°C, followed by slow furnace-cooling. I found that acoustic guitar was handled without problems by the mic, which delivered both the depth and woodiness of the body sound, and the transient detail of the strings. I also managed to coax a very sweet, woody sound out of a mandolin when the mic was positioned about 12 inches from the sound hole. The SE4400a sounds good on hand percussion too, including bodhran, so it should work as a drum overhead or general percussion mic too. Because the response is pretty flat, with plenty of low‑end extension, there's no reason not to expect a stereo pair to turn in good results on piano, although I didn't have the chance to try this during the review.

Incontrol protect - SOS emergency call with automatic collision detection, optimised assistance call and Incontrol remote app essential This article presented a brief summary of the properties, strength, and applications of 440 steel.

Sources: Sure, there is better out there... but in my experience, to get something better, be ready to spend no less than double the money for minuscule improvements and many thousands more if you want to get barely audible results. The SE4400a is clearly designed as a general‑purpose mic, so I wasn't surprised to find that it had no overbearing tonal characteristics. Its presence peak gives it a slightly flattering, larger‑than‑life vibe, but in a pretty subtle way that doesn't make things sound too harsh, and the low end gains useful support from a little added warmth. The general tonality also remained reasonably consistent between patterns — taking the proximity effect out of the equation, of course.

The item has lots of wear and tear including scratches, dents, chips, tarnishing and in the case of amps, tears in the tolex covering. The item has been heavily used with lots of cosmetic wear and tear. This can include deep scratches, large chips, heavy tarnishing to the hardware and strong discolouration. When used with an appropriate threshold seal, and door, the 1212 has an R wof 31dB when used with an acoustic doorset assembly. It is also important to know that 440 steels do not work well at temperature extremes. They lose their strength when at high temperatures because they over temper and become softer, and they lose their ductility at a temperature below 0 o Celsius. This fact is important to any designer that wishes to implement this steel in particularly harsh environments, as 440 steel would probably not be the best choice. Mechanical Properties The following section discusses the properties of grade 440 bar products covered under ASTM A276. These values may not be similar to that of other forms such as forgings and plates.

We tested the mic on spoken and sung vocals, getting excellent results on the spoken voice recordings, as well as on acoustic guitar and violin. Across the board we were impressed, with a very good performance and full-bodied sound emanating from the guitar in particular. Grade 440C stainless steels are high carbon steels, which attain the highest hardness, wear resistance and strength of all stainless steel grades after heat treatment. These properties make this grade suitable for applications such as valve components and ball bearings. Grade 440A and 440B stainless steels, on the other hand, have similar properties - except for a slightly lower percentage of carbon in grade 440A.The item is in “as new” condition with no discernible cosmetic wear. It will include all original parts and accessories. You can find any number of Chinese‑built microphones at the budget end of the market, but SE are one of the very few companies to own a microphone factory in China — rather than having their mics made for them in one of the huge factories in Shanghai or Bejing that specialise in building mics or capsules for third‑parties. Certainly, this has helped SE to build a strong reputation for value at the affordable end of the market, but they also make more up‑market microphones, many with innovative design features, such as the Titan's titanium diaphragm or the Gemini's dual-tube, transformerless circuitry. Overview The metals that are characterized as steel are a diverse class of materials that are an integral part of modern society. Steel is an alloy that is made by combining iron with carbon as well as other elements that provide it with unmatched strength. Since its beginnings in the early 20th century, steel has proliferated into hundreds of types, each with its own unique material profiles. To help organize these steels, The American Iron & Steel Institute (AISI) and the Society of Automotive Engineers (SAE) have distinguished certain steel types, and this article will explore a steel class from the stainless steels or those which are more resistant to stains, corrosions, and rust. This stainless steel class is known as the 440 steels, and it is a highly popular material thanks to its hardness and resistance to wear. This article will investigate the characteristics, material properties, and applications of 440 steel so that readers can understand where it can be used and how to best apply this metal. Physical Properties of 440 Steel Time in the car on home soil shows that Land Rover is on a roll. Following on from the full-size Range Rover, this more dynamic Sport is still superbly luxurious. It offers the kind of ride comfort, refinement, interior quality and technology you would expect from a car costing so much, but it balances this with a more engaging edge to its dynamic personality that sends the newcomer straight to the top of a toughly contested class. A frequency response of 20Hz‑20KHz is quoted. On its own, this means relatively little, but the frequency plot is somewhat more revealing and shows a nominally flat response, but with a gentle presence peak at around 10kHz. This type of response tends to produce a largely natural sound, but with an extra sense of clarity at the high end, making it suitable for a wide range of acoustic instruments from piano and acoustic guitars to drum overheads. The sensitivity of 14.1mV/pa‑34 (±1dB) puts the mic's output in the same ball‑park as most other similar studio mics, and although its equivalent noise level of 17dB (A-weighted) isn't outstandingly low, it is again pretty typical for this type of microphone, and certainly quiet enough for most studio tasks. A maximum SPL for 0.5 percent THD at 1kHz is quoted as 130dB, but I suspect that this is extended when the pads are switched in.

Karp, Theodore (1983). Dictionary of Music. Northwestern University Press. p.406. ISBN 9780810106598.Small size and a choice of polar patterns make this mid‑priced, large‑diaphragm mic a very versatile performer. I had done a little bit of my homework before pulling the trigger on these mics, but none of that really prepared me for just how good they are. In 1936, the American Standards Association recommended that the A above middle C be tuned to 440Hz. [5] This standard was taken up by the International Organization for Standardization in 1955 as Recommendation R 16, [6] before being formalised in 1975 as ISO 16. [7] A440 (also known as Stuttgart pitch [1]) is the musical pitch corresponding to an audio frequency of 440 Hz, which serves as a tuning standard for the musical note of A above middle C, or A 4 in scientific pitch notation. It is standardized by the International Organization for Standardization as ISO 16. While other frequencies have been (and occasionally still are) used to tune the first A above middle C, A440 is now commonly used as a reference frequency to calibrate acoustic equipment and to tune pianos, violins, and other musical instruments. It also means the Sport is a consummate motorway cruiser and easy around town; there really are very few situations where the car doesn’t feel at home.
