It has a very high-quality performance and modern sound character.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe GA-8000 uses a ROGERS ceramic\u003c\/strong\u003e circuit board that has superior insulation parameters and offers a more stable performance. The coupling and bypass capacitors is of a very high quality, resulting in a deep and exact low frequency performance and a delicate and transparent high frequency reproduction.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe semiconductor active\u003c\/strong\u003e cooling and external cooling system is used in the GA-8000 ensures that the GA-8000 has the highest possible signal-to-noise ratio. The tube (a 6AU6) is mounted in an aluminum casing, with the semiconductor cooling chip being attached to the bottom of the case.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe temperature of the tube in the GA-8000 is\u003c\/strong\u003e the effectively kept down when the GA-8000 is in it´s working state, the heat generated by the tube is actively dissipated. The heat that the tube generates is transferred to the reverse side of the semiconductor and transferred to the effective outer aluminum alloy heat sink at the rear of the microphone. This heat sink will then dissipate the heat from semiconductor cooling chip to the air surrounding the GA-8000.\u003c\/p\u003e\n\u003ch3\u003ePCB Board\u003c\/h3\u003e\n\u003cp\u003eA ROGERS ceramic gold-plated circuit board is used. This type of circuit board is usually used in high-end aerospace communication products, the cost is about twenty (20!) times higher than an ordinary PCB board.\u003c\/p\u003e\n\u003ch3\u003eCapsule\u003c\/h3\u003e\n\u003cp\u003eA manufacturer with more than twenty years of microphone capsule production experience are producing a capsule that have a modern sound character. The capsule used in the GA-8000 can handle a high sound pressure level.\u003c\/p\u003e\n\u003ch3\u003eTube\u003c\/h3\u003e\n\u003cp\u003eIn order to ensure the tube will have a long life, we are using a NOS CIFTE 6AU6 tube from France, it has a maximum anode voltage rating of about 300V. The tube in this circuit has an anode voltage of 90V and will generate more heat than tubes in many other tube microphones that typically uses voltages between 35-50V. The higher voltage used in the GA-8000 increases the heat dissipation so the semiconductor active cooling system is an important element in the design.\u003c\/p\u003e\n\u003ch3\u003ePower Supply\u003c\/h3\u003e\n\u003cp\u003eThe GA-8000 uses a modern power supply with solid state rectifiers and a FET based stabilizer for the high voltage rail.\u003c\/p\u003e\n\u003cp\u003eAfter a lot of listening tests comparing a tube rectifying circuit with a solid state one, we found that we did prefer the sound of the latter so this is what we decided to use. The additional advantage is that there is no need to worry about replacing tubes in the power supply.\u003c\/p\u003e\n\u003ch3\u003eCapacitors, Resistors and Solder\u003c\/h3\u003e\n\u003cp\u003eThe metal resistors and electrolytic capacitor from Japan are of special audiophile audio types.
