Mic Roundup Part 1: Mics Inspired by the Neumann U47 and AKG C12Built according to the original production documents and schematics of the classic design, the Neumann U 47 fet i Large-Diaphragm Cardioid Condenser Microphone is a precise reproduction of this often-copied microphone that helped define the smooth sound of the ’70s. A transistorized version of their legendary U 47 tube mic, the U 47 fet i features the same classic K 47 dual-diaphragm capsule as the U 47 and boasts high SPL handling, commonly finding itself at home outside of a kick drum and in front of loud guitar and bass amps. Like the original, there is a slight boost in frequency response around 2 kHz.
The mic features the same 140 Hz low-cut filter as the original as well as the selectable -10 dB pad to raise the maximum SPL from 137 to 147 dB. For additional attenuation, there is a -6 dB output switch, allowing you to hit your mic preamps at a lower level in case you want to use more gain and coloration via the preamp. Thanks to the integrated swivel mount and included thread adapter, the U 47 fet i can easily be positioned on any mic stand. Unlike the U 47 tube mic, the U 47 fet i requires 48V phantom power.The Sound of the Seventies”Smooth” is the word that best describes the sonic ideal of the ’70s. The then-new U 47 fet was very much part of that sound. Introduced in 1972, it soon became a studio favorite combining the refined sound balance of its tube predecessor with a new clarity and greater ease of use. In the ’80s, as records became increasingly more strident, the smooth U 47 fet fell out of favor as a vocal microphone and was discontinued. Yet over the years, top engineers discovered new applications for the U 47 fet in front of guitar cabinets and kick drums. Eventually, famous vocalists from boy group pop to heavy metal reestablished the U 47 fet as a versatile vocal microphone. So now, by popular demand, it’s back in production.Far from OutdatedThe U 47 fet uses the same K 47 large-diaphragm condenser capsule and the same headgrille design as its tube-operated predecessor, the legendary U 47, which revolutionized the recording and broadcast industries from 1949 to 1960. For sonic continuity, the U 47 fet also uses a similarly oversized output transformer. Otherwise, its transistorized head amplifier is an amazingly advanced design and a testament to Neumann’s state-of-the-art engineering. This “vintage” microphone has a dynamic range of 119 dB.Versatile ApplicationsThe U 47 fet can handle extreme SPLs of up to 137 dB, and even 147 dB with the -10 dB pad switch engaged. This, along with its smooth top end and lush midrange, makes the U 47 fet an excellent microphone for bright and loud instruments such as brass and electric guitar. Due to its exceptionally clear and uncluttered low end, it is a great choice for upright bass and bass cabinets. Numerous top engineers consider U 47 fet the ultimate microphone to place in front of the kick drum. At the same time, it is an excellent vocal mic for crooners and screamers alike, due to its beautifully balanced response with just a slight, unobtrusive boost in the upper mids for added presence in the mix.No Shockmount NeededThe U 47 fet comes with a special one-sided swivel mount, which makes it easy to position. Pad and low-cut switches are accessible on the rear of the microphone. An additional switch next to the XLR socket allows for attenuating the output signal by 6 dB, which is a handy feature in conjunction with low-headroom vintage preamplifiers.Features at a GlanceExact reproduction of the classic U 47 fet (1972 to 1986)Solid-state successor of the legendary U 47 tube microphoneBalanced sound with superb presenceK 47 large-diaphragm condenser capsuleCardioid polar patternLarge output transformerLow self-noise and high SPL capabilityIntegrated swivel mount with 5/8″-27 threadIncludes thread adapter for 1/2 and 3/8″ standsXLR 3-pin output connector48V phantom powerIncludes wooden boxWhatsApp:+8615989288128 , UNCUCO Radio / TV Studio Equipment. , 615104064270
