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 signal amplification to directly drive the power amplifier, obviously powerful and nice, and the effect is immediate. Don't take it off once used.   600Ω: 15K impedance description: 600Ω 15K refers to the input and output AC impedance of the transformer, not the resistance of the primary and secondary windings (copper resistance).   600Ω:15K 5 times boost calculation: The secondary 15K divided by the primary 600Ω and the open root is equal to 5, that is, 5 times boost amplification, which is also suitable for calculation of other impedance transformers.   The working principle of the transformer amplified signal: 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 through the turns of the primary winding and the secondary winding By the ratio, different voltage ratios can be obtained, and voltage boosting and amplification can be carried out. This is the principle of transformer boosting and amplification.   For example, the input coil of the transformer is wound with 10 turns, the output is wound with 50 turns, the input 1V output can be 5V, the signal is boosted by 5 times, the turns ratio is also the voltage ratio, and the turns ratio is also equal to the secondary impedance divided by the primary impedance. . The signal transformer can work without an external power supply and is a passive amplifier device.   The 5 times amplifier transformer can solve the problem of sound system without pre-amplifier and low volume, and can replace active pre-amplifier.   Install the shielding cover and double-sided circuit board in pairs with two transformers   Fixed transformer double panel 63X53mm plate thickness 2mm shielding cover 36x28x20mm     This transformer can be used from single-ended to single-ended, single-ended to balanced, balanced to balanced, and balanced to single-ended. There are 4 types of wiring as shown below:

The magnetic head of the reel tape drive, the vinyl LP cartridge booster cattle, the American Ares Jensen audio cattle, the Swedish LUNDAH Lunda cattle, the British GARDNERS audio cattle, the Japanese TAM Temulan audio cattle, etc. are almost exclusively used permalloy materials. Because the permalloy material has high permeability and low iron loss, it can work well with weak signals and high transmission efficiency, so permalloy is an ideal material for audio signal transformation.

High-purity oxygen-free copper and red copper enameled wire winding, precision CNC automatic winding machine equipment.

Another 600:15K finished machine is installed. The iron shell size is the same as the American Ares 10K:10K audio isolator, 110mm long x 65mm deep x 32mm high. The iron shell effectively shields the electric field and stray magnetic field, reduces the hum, and makes the background quiet. Gold-plated RCA socket with excellent contact performance.
