The appearance of this product is from Neuman U87, and the circuit board is from SE2200 condenser microphone. In general, I have repaired countless condenser microphones, and some of them can't impress me. Only some excellent lines will be recorded by me. This circuit is one of them. This circuit has a circuit similar to U87, and the two stages are class a amplifier circuit. The first stage amplifier circuit is the same as the U87, and the second stage amplifier circuit is more than one level than the U87, so the gain is It will be larger than the U87. After two stages of amplification, a balanced audio signal is output from the output cow (impedance 200 ohm, consistent with the output of the U87).
Generally, among all the microphones I develop, I pay more attention to the sound quality effect. I adjust any microphone style to the low tone, steady and strong, and the medium and high pitch require transparent. This microphone does exactly that. Over the years, we have made more than 12 types of microphones, which have been highly praised by professional recording engineers, amateurs and DIY enthusiasts. Each microphone line has a different sound style. At the same time, it has been copied and copied by peers without any changes. Their price is higher than that of our store. Here, I would like to thank colleagues for their recognition.
Appearance: this microphone has a bright spot, no matter the sound or the shell, the material used is more excellent. The shell is treated by the world popular nickel plating process (natural color nickel is also called pearl nickel), and the internal framework is treated with bright nickel plating process, and the workmanship level has reached the highest level in the world. Appearance and internal sound effect into one, can be said to be a good wheat.
Shell details: feel cold with your hands, and the surface is smooth enough to leave fingerprints (the fingerprints can be seen only by the side light)
Advantages of nickel plating: make metal not easy to be oxidized by air, durable.
Materials for internal components: the use of the world's audio world's more famous fever capacitor, after my tone tuning carefully selected. The transformer side adopts permalloy transformer developed by myself, with perfect impedance matching, transparent and full voice.
Capsule head: using gold-plated large diaphragm condenser microphone capsule.
Conclusion: if you are a music lover, selfie control, audio enthusiast, professional musician pursuing perfection and this microphone will not disappoint you.
