Handmade in small batches, the GA-47 will be your new favorite go-to mic. Dripping with tone and nostalgia from an era of crooners, rock and roll, to today’s biggest hits, the GA-47 offers you all the tone you’ve come to expect from a 47.\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003eThe Neumann U-47 microphone is one of the most highly revered and sought after microphones of all times. Being a true classic, the U-47 really needs no further presentation.\u003c\/p\u003e\n\u003cp\u003eDue the high cost and low availability of vintage originals, especially ones in good condition, a number of manufacturers are producing U-47 clones. The selling price of the clones are covering a broad price span, several of them are sold at high price points.\u003c\/p\u003e\n\u003cp\u003eAny manufacturer putting a U-47 clone on the market is bound to get the same question: “Does it sound like a U-47?”.\u003c\/p\u003e\n\u003cp\u003eMy take is that this is the wrong question to ask, I would like to rephrase the question to: “Does it offer the classic qualities and advantages that a vintage U-47 in perfect condition do?”\u003c\/p\u003e\n\u003cp\u003eThe Neumann U-47 was produced between 1949 and 1965 meaning that the vintage original units are now very old and their performance do differ a lot depending on their condition. The different clones all have their specific sound character too. So, it´s not easy to say which sound is “the right one”. As always, not the least as microphones goes, it will ultimately be a matter of taste.\u003c\/p\u003e\n\u003cp\u003eThe Golden Age Premier GA-47 is the result of a lot of hard work and real world testing and the MKII version has been further refined. The end result is a microphone with a very sweet character that should appeal to a great number of users and a microphone that can be used for the most demanding recording tasks. It has proved itself to be a great all-rounder, this is not a “vocal-only” microphone.\u003c\/p\u003e\n\u003cp\u003eThe GA-47 MKII is not a product that is built in huge quantities on a big assembly line. It´s a product that is built by hand, fifty units at a time in a small workshop by a skilled and dedicated staff. It uses very high quality components all the way to achieve the goal of offering classic U-47 qualities.\u003c\/p\u003e\n\u003ch3\u003eMic Body and Grille\u003c\/h3\u003e\n\u003cp\u003eThe mic body is made of brass, the grille is made of iron. The grille, which is a critical component affecting the sound character, is similar to the one in the U47.\u003c\/p\u003e\n\u003ch3\u003eCapsule\u003c\/h3\u003e\n\u003cp\u003eThe capsule for the GA-47 MKII is designed to provide the requirements of modern day recordings by mixing the character between a vintage K47 capsule and the one from a K67-style capsule with a wide frequency response and high sensitivity. The result is a truly great sound.\u003c\/p\u003e\n\u003cp\u003eBeing a dual-sided one, it provides the GA-47 with both cardioid and omni polar patterns.\u003c\/p\u003e\n\u003cp\u003eIn order to get a good consistency between units, for each production run of 50 pcs GA-47 units, approximately 200 capsules is evaluated in order to find 50 capsules with specifications that lie within the tight tolerances.\u003c\/p\u003e\n\u003ch3\u003eTube\u003c\/h3\u003e\n\u003cp\u003eThe GA-47 MKII uses a selected NOS Telefunken EF-800 series super low noise pentode tube connected in triode mode in order to decrease distorsion and noise. This tube is modern glass derivative of the VF14M used in the vintage U-47.\u003c\/p\u003e\n\u003ch3\u003eOutput Transformer\u003c\/h3\u003e\n\u003cp\u003eThe GA-47 MKII transformer is especially designed with a 6.5:1 dual bobbin transformer by a reputed transformer factory. It is a replica of the BV8 transformer used in the vintage U47. It uses a high quality core material.\u003c\/p\u003e\n\u003ch3\u003eCapacitors and Resistors\u003c\/h3\u003e\n\u003cp\u003eThe coupling capacitor is made in United Kingdom, the brand is Ciarit, the same type used in the famous and very expensive B\u0026amp;W Nautilus loudspeaker. It is an axial capacitor made from MKP material with copper pins. It has a delicate, full sound and a wide frequency response.\u003c\/p\u003e\n\u003cp\u003eOther used capacitors are MIAL polystyrene film capacitors with very low loss. The resistors are ALLEN BRADLEY carbon film resistors made in the USA with vintage and warm sound.\u003c\/p\u003e\n\u003ch3\u003eMic Interior and Cabling\u003c\/h3\u003e\n\u003cp\u003eThe electronic circuit is built with point-to point wiring on an expensive Rogers circuit board. Teflon insulated, silver-plated copper wire is used for the internal connections.\u003c\/p\u003e\n\u003ch3\u003ePower supply transformer and electrolytic capacitors\u003c\/h3\u003e\n\u003cp\u003eThe vintage style power supply PSU uses a high power R-style transformer with a low noise level and a minimal stray field. The electrolytic capacitors are of a high quality audio style type.\u003c\/p\u003e\n\u003cp\u003eA simple but effective circuit uses dual-stage filtering for the filament voltage. The high voltage is precisely filtered and stabilized using an ON semiconductor zener diode.\u003c\/p\u003e\n\u003ch3\u003eMic Cable\u003c\/h3\u003e\n\u003cp\u003eThe cable is specially produced using 99,99% pure oxygen-free copper, Teflon insulation, tin foil and 98% kitmesh, ie with a very high braided density of the cable shield. It has a very open and smooth sound.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThe connectors are gold plated.\u003c\/li\u003e\n\u003cli\u003eMic and psu circuit in relation to the original mics\u003c\/li\u003e\n\u003cli\u003eThe polar pattern switch is located on the power supply allowing for easy sound comparisons.\u003c\/li\u003e\n\u003cli\u003eThe circuit used in the GA-47 MKII is similar to the U-47 but the component values has been adjusted to fit the EF-800 tube.\u003c\/li\u003e\n\u003cli\u003eThe circuit used for the power supply is also similar except for adding a zener diode to assure the voltage and current stable.\u003c\/li\u003e\n\u003cli\u003eThe connectors are gold plated. All three connectors are placed on one side to facilitate handling and

The Neumann U-47 microphone is one of the most highly revered and sought after microphones of all times. Being a true classic, the U-47 really needs no further presentation.

Due the high cost and low availability of vintage originals, especially ones in good condition, a number of manufacturers are producing U-47 clones. The selling price of the clones are covering a broad price span, several of them are sold at high price points.

Any manufacturer putting a U-47 clone on the market is bound to get the same question: “Does it sound like a U-47?”.

My take is that this is the wrong question to ask, I would like to rephrase the question to: “Does it offer the classic qualities and advantages that a vintage U-47 in perfect condition do?”

The Neumann U-47 was produced between 1949 and 1965 meaning that the vintage original units are now very old and their performance do differ a lot depending on their condition. The different clones all have their specific sound character too. So, it´s not easy to say which sound is “the right one”. As always, not the least as microphones goes, it will ultimately be a matter of taste.

The Golden Age Premier GA-47 is the result of a lot of hard work and real world testing and the MKII version has been further refined. The end result is a microphone with a very sweet character that should appeal to a great number of users and a microphone that can be used for the most demanding recording tasks. It has proved itself to be a great all-rounder, this is not a “vocal-only” microphone.

The GA-47 MKII is not a product that is built in huge quantities on a big assembly line. It´s a product that is built by hand, fifty units at a time in a small workshop by a skilled and dedicated staff. It uses very high quality components all the way to achieve the goal of offering classic U-47 qualities.

Mic Body and Grille

The mic body is made of brass, the grille is made of iron. The grille, which is a critical component affecting the sound character, is similar to the one in the U47.

Capsule

The capsule for the GA-47 MKII is designed to provide the requirements of modern day recordings by mixing the character between a vintage K47 capsule and the one from a K67-style capsule with a wide frequency response and high sensitivity. The result is a truly great sound.

Being a dual-sided one, it provides the GA-47 with both cardioid and omni polar patterns.

In order to get a good consistency between units, for each production run of 50 pcs GA-47 units, approximately 200 capsules is evaluated in order to find 50 capsules with specifications that lie within the tight tolerances.

Tube

The GA-47 MKII uses a selected NOS Telefunken EF-800 series super low noise pentode tube connected in triode mode in order to decrease distorsion and noise. This tube is modern glass derivative of the VF14M used in the vintage U-47.

Output Transformer

The GA-47 MKII transformer is especially designed with a 6.5:1 dual bobbin transformer by a reputed transformer factory. It is a replica of the BV8 transformer used in the vintage U47. It uses a high quality core material.

Capacitors and Resistors

The coupling capacitor is made in United Kingdom, the brand is Ciarit, the same type used in the famous and very expensive B&W Nautilus loudspeaker. It is an axial capacitor made from MKP material with copper pins. It has a delicate, full sound and a wide frequency response.

Other used capacitors are MIAL polystyrene film capacitors with very low loss. The resistors are ALLEN BRADLEY carbon film resistors made in the USA with vintage and warm sound.

Mic Interior and Cabling

The electronic circuit is built with point-to point wiring on an expensive Rogers circuit board. Teflon insulated, silver-plated copper wire is used for the internal connections.

Power supply transformer and electrolytic capacitors

The vintage style power supply PSU uses a high power R-style transformer with a low noise level and a minimal stray field. The electrolytic capacitors are of a high quality audio style type.

A simple but effective circuit uses dual-stage filtering for the filament voltage. The high voltage is precisely filtered and stabilized using an ON semiconductor zener diode.

Mic Cable

The cable is specially produced using 99,99% pure oxygen-free copper, Teflon insulation, tin foil and 98% kitmesh, ie with a very high braided density of the cable shield. It has a very open and smooth sound.

  • The connectors are gold plated.
  • Mic and psu circuit in relation to the original mics
  • The polar pattern switch is located on the power supply allowing for easy sound comparisons.
  • The circuit used in the GA-47 MKII is similar to the U-47 but the component values has been adjusted to fit the EF-800 tube.
  • The circuit used for the power supply is also similar except for adding a zener diode to assure the voltage and current stable.
  • The connectors are gold plated. All three connectors are placed on one side to facilitate handling and placement.

Specifications

  • Frequency Response: 20Hz-20KHz
  • Sensitivity: 12mV/Pa
  • Rated Impedance: 200 ohms
  • Equivalent Noise Level: 10dB
  • Max S.P.L: 140dB
