sE4400a Large Diaphragm Multi Pattern Condenser Microphone

Product Information

During welding, grade 440 stainless steels are pre-heated at 250°C, followed by full annealing. Grade 420 filler rods can be used to achieve a high hardness weld. Grade 309 or 310 filler rods will, however, provide soft welds, having high ductility. ISO 16:1975(en) Acoustics — Standard tuning frequency (Standard musical pitch)". International Organization for Standardization . Retrieved 2022-03-09. 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.

The sound of sE mics is hard to sum up as it's so transparent and natural, but all we can say is that the 4400a continues sE's tradition beautifully. It doesn't unnaturally colour vocal recordings, but the sound is clear and tight and does what vocal recordings really need to do - leave you with a result that will respond well to any EQ and compression treatment you have in mind for the mix stage. For example, the sE4400a is easy to position so its capsule is just peeking over the top of the rim of a snare drum. Speaking of the capsule, it's based on a retuned version of the capsule in the SE2200A (I wish SE Electronics were consistent with capitalization of their product names), which I consider one of the best values in microphones; I use it more often than mics in my closet that cost ten times as much. In direct comparison to the SE2200A (Tape Op #48), the sE4400a in cardioid mode brings out significantly more of the snare drum's punch whether up close, at medium distances, or placed far. I can hear much more resonance of the drum's body. There is perceivably less of the actual snare wires coming through, no matter how I angle the mic, but also less of the undesirable "spit". Hypercardioid and figure-8 modes are useful for rejecting high-hat bleed, but of course, polar-response selection also affects how much room and "floor" (reflection of the snare from the floor -or in my case, a clipboard lying flat on the rug below the snare) the mic captures. On vocal, the SE2200A has more midrange (especially upper mids), so I find it cuts through the mix better. But the sE4400a has more "chest", especially for male vocals. Proximity effect is also smoother, and it doesn't jump in with sudden chestiness at 3" or less like the SE2200A can. Also, the sE4400a exhibits much less sibilance (but that also means it's a little less "exciting" -or should I say "dangerous" -than the SE2200A). Compared to the Neumann TLM 49 (Tape Op #61), on male vocals, the sE4400a seems to have more high-end hype and more chestiness at all distances. The TLM 49 has much smoother proximity effect and is therefore an easier mic for a vocalist to work. Compared to the Shure KSM32 (Tape Op #16), one of my go-to mics for vocals, especially when I want a buttery-smooth midrange, the sE4400a, with its slight high-end bump, draws out a bit more highs and breath, but without ever sounding shrill. Ensure that the surface which the seal is to be adhered to is clean, smooth and if painted, well cured. 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.ISO 16:1975 Acoustics – Standard tuning frequency (Standard musical pitch). International Organization for Standardization. 1975. 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:

A440 is widely used as concert pitch in the United Kingdom [8] and the United States. [9] In continental Europe the frequency of A 4 commonly varies between 440Hz and 444Hz. [8]Small size and a choice of polar patterns make this mid‑priced, large‑diaphragm mic a very versatile performer. These grades have a corrosion resistance lower than that of other austenitic grades. The applications of martensitic steels are limited by the loss of strength caused by over-tempering at high temperatures, and loss of ductility at temperatures below zero. Fully tested for performance and durability under the third party certification schemes CERTIFIRE and BBA

Whether you're searching for a single microphone to carry out all of your recording tasks, or looking to add to an existing library of models with a microphone you can throw into a bag for a session and pull out for almost any application, the 4400a is definitely more than up to the job.

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. 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. When used with an appropriate threshold seal, and door, the 1212 has an R wof 31dB when used with an acoustic doorset assembly.
