Description
Luge LG AUDIO Permalloy 600Ω: 15K audio signal transformer, signal 5 times amplification, 5 times passive amplification without electricity, especially suitable for mobile phone or audio source signal amplification to directly drive the post-stage power amplifier, obviously powerful and beautiful, the effect is immediate, I don't want to take it down once I use it.
600Ω: 15K impedance description: 600Ω 15K refers to the input and output AC impedance of the transformer, not the resistance (copper resistance) of the primary and secondary coils.
600Ω: 15K 5 times boost calculation: After the secondary 15K is divided by the primary 600Ω, the root number is equal to 5, that is, 5 times boost amplification, which is also applicable to other impedance transformer calculations.
Transformer amplified signal working principle: when the audio signal enters the primary winding of the transformer, the coil and the iron core will induce an alternating electromagnetic field, and the alternating electromagnetic field will induce a signal voltage in the output winding, passing the number of turns of the primary winding and the secondary winding Ratio, you can get a different voltage ratio, you can carry out voltage boost amplification, this is the principle of transformer boost amplification.
The 5X amplification transformer can solve the problem of low sound volume in the audio system without pre-amplification and can replace active pre-amplification.
Fixed transformer double panel 63X53mm board thickness 2mm shield 36x28x20mm
This transformer can be used from single-ended to single-ended, single-ended to balanced, balanced to balanced, balanced to single-ended. There are 4 types of wiring as shown below:

Opening tape drive heads, vinyl LP phono booster cattle, American God of War Jensen audio cattle, Swedish LUNDAH Lunda cattle, British GARDNERS audio cattle, Japanese TAM Tiemulan audio cattle, etc. almost all use permalloy materials, It is because the permalloy material has high magnetic permeability and low iron loss, and the small signal can work well, and the transmission efficiency is high, so permalloy is an ideal material for audio signal transformation.
