600:10K permalloy Audio Signal Boost Isolation Transformer 4 Times Amplification. Suitable for Audio Microphone

power converterPermalloy 600:10K audio signal step-up isolation transformer for audio and microphone: audio step-up transformer wound with imported EE19 permalloy material permalloy material transformer shield can filter and shield AC noise interference digital taste .Suitable for microphone CD MP3 MP4 hard disk player deck LP multimedia audio source input the signal is boosted to the next level by the isolation transformer signal and sold in pairs.The voltage ratio of 600:10K is 1:4. That is to say 600 ohms input 1V signal voltage the output voltage of the 10K winding is 4.082V and the signal is increased and amplified by 4 times.The transformer core is made of imported EE19mm permalloy material with a content of 80%. The core is white and shiny which can be identified at a glance. Permalloy is non-rusting and resistant and can be used for a long time.E19 core size: length 19mm × height 16mm × stack thickness 8mm. The transformer is shielded by red copper foil and the copper shield can reduce leakage inductance reduce distributed capacitance and significantly improve the use effect. The shield should be grounded when in use.High-purity oxygen-free copper enameled wire is wound and sold with similar inductance and resistance values. The measured value is marked on the transformer. The connection must be correct when using it otherwise it will not work properly!The primary DC resistance is about 200 the inductance is about 2.5 to 3H and the secondary DC resistance is about 800 and the inductance is about 30 to 40H.Measured frequency response 200Hz ~ 22KHz -0.5DB 100Hz -35KHz -1DB DC withstand voltage of 500V.The transformer has been tested to ensure that the primary and secondary windings are normal there is no open circuit short circuit or leakage and the transformer pins are normal and not looseThere are the following three connection methods for reference!Note: In order to broaden the frequ
