sE4400a Large Diaphragm Multi Pattern Condenser Microphone

Product Information

The mic also sounds great on piano, violin, clarinet, toms, and even handclaps. And with its integrated pad switch, I have yet to overload its all-discrete Class A FET electronics. It's not always the most flattering mic, but it's never a bad choice. Grade 440 stainless steels should not be used at temperatures below the relevant tempering temperature, due to loss of mechanical properties caused by over-tempering.

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 Grade 440 stainless steels exhibit excellent resistance to mild acids, alkalis, foods, fresh water and air. A smooth polished surface also helps grade 440 steels resist corrosion in tempered, passivated and hardened conditions. 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. All three forms of grade 440 steels are commonly used. However, grade 440C is more readily available than the other standard grades. Grade 440F, a free-machining type of grade 440 series, is also available with a high carbon content similar to that of grade 440C. Martensitic steel grades are high-hardness steels, usually fabricated using techniques that require hardening and tempering treatments. Matched pairs are available as an option for a slightly increased cost, but these come in a camera‑style case, with a sturdy metal mounting-bar so that you can use the mics as a spaced stereo pair. PerformanceHardening — Grade 440 stainless steels are heated at 1010 to 1065°C, then quenched in air or oil. Oil quenching is usually carried out for heavy sections. Following this process, these steels are tempered at temperatures from 150 to 370°C, to achieve a high hardness and improved mechanical properties. steel can be found in most machine shops, as it is an easy metal to machine when annealed and yet is strong and resilient when heat treated. This material is exceptionally good for components that must resist corrosion relatively well and yet not wear under repeated use. It is a great steel for knife edges, as its hardness yet formability excels when used for kitchen cutlery. There are some other notable applications of 440 steel, listed below: 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 American music industry reached an informal standard of 440Hz in 1926, and some began using it in instrument manufacturing.

Karp, Theodore (1983). Dictionary of Music. Northwestern University Press. p.406. ISBN 9780810106598. Before standardization on 440Hz, many countries and organizations followed the French standard since the 1860s of 435Hz, which had also been the Austrian government's 1885 recommendation. [2] Johann Heinrich Scheibler recommended A440 as a standard in 1834 after inventing the "tonometer" to measure pitch, [3] and it was approved by the Society of German Natural Scientists and Physicians at a meeting in Stuttgart the same year. [4] 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.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. Grade 440 stainless steels can be easily machined in their annealed state. Machining these grades after hardening is extremely difficult, or impossible in some cases. Whether buyers actually plump for the Range Rover Sport for its extra dynamic edge, or the difference in style compared with the new full-fat Range Rover, this latest Sport redesign isn’t as radical as the one its bigger brother received. Instead, it’s more of a concentrated, focused evolution of the breed, with the brand’s ‘reductionism’ theme being successfully applied to the Sport’s still vast but hunkered-down body. In our opinion, at least.

Just as good with vocals as they are on brass, drums, woodwind and strings. To top it off, I use them mostly to record my accordions and I cannot believe how accurately they capture the realism of the performance.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. steel has impressively high strengths, as can be seen through its ultimate and tensile yield strengths. These measures come from experimental stress tests, where a specimen of 440 steel is pulled apart axially and its strain vs. stress is plotted on a curve. The yield stress is the maximum amount of stress a specimen can experience before plastically (or permanently) deforming, and the ultimate strength is the maximum stress experienced by the specimen before it fractures. These measures are useful in structural applications, where a material must not permanently deform under intense weight, and in high-stress applications where failure must not occur.
