Permallo 600: 10K audio signal boost isolation transformer for audio and microphone: Audio step-up transformer, imported EE19 permalloy material winding, permalloy material transformer shield, which can filter and shield AC noise interference .
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 paired for sale.
The 600: 10K voltage ratio is 1 to 4. In other words, the input voltage of 1V signal is 600 ohms, and the output voltage of the 10K winding is 4.082V. The signal is boosted and amplified by 4 times.
Transformer iron core uses 80% imported EE19mm permalloy material. The iron core is white and shiny, and it can be recognized at a glance. Permalloy is non-rusting and corrosion-resistant, and can be used for a long time.
E19 iron core size: length 19mm × height 16mm × stack thickness 5mm. Transformer copper foil shielding, copper shielding can reduce leakage inductance, reduce distributed capacitance, and significantly improve the use effect. The shield should be grounded during use.
High-purity oxygen-free copper enameled wire is wound, and the inductance and resistance are selected and sold similarly. The measured value is marked on the transformer. The connection must be correct during use, otherwise it will not work properly!
The primary DC resistance is about 200Ω and the inductance is about 2.5 to 3H. The secondary DC resistance is about 800Ω and the inductance is about 30 to 40H.
Measured frequency response, 200Hz ～ 22KHz -0.5DB,
100Hz to 35KHz -1DB,
DC withstand voltage 500V.
The transformer has been tested to ensure that the primary and secondary windings are normal, and there are no open circuits, short circuits, or leakages.

Note: In order to widen the frequency response and reduce leakage inductance, the secondary pole of the transformer is not the conventional parallel winding method. The copper resistance at the two ends of the coil center tap will have different errors. The copper resistance error caused by inconsistent perimeter dimensions does not affect the balance use, and the perfectionists who use it for balance require careful purchase
Note: There are errors in the measurement of size, inductance and resistance. Transformer is mainly based on inductance value. Buy two and choose and sell with similar inductance value.
