The transformer has a constant impedance in the whole frequency band, which can effectively solve the problem of impedance and interface matching (such as single-ended and balanced). The signal can be effectively amplified and attenuated. Transformer conversion is a simple design scheme, short path, effective route, and direct route. The impedance matching is strong before and after, good effect, high fidelity, full of charm.
LG AUDIO Z11 material 600Ω: 600Ω audio signal isolation transformer, signal input and output 1 to 1. Imported Z11 material 4N oxygen-free copper and copper enameled wire winding. Mark the parameters on the sold transformers and match the boards!
Z11 material's 600Ω: 600Ω signal transformer wide frequency response, 10Hz ~ 72KHz -1DB, is rare in the industry business counterparts.
High-quality Luge Z11 silicon steel sheet material 600Ω: 600Ω audio transformer, referring to the imported big brand audio cattle winding method. Transformer Three-wire input three-wire output, balanced input balanced output, single-ended input single-ended output, can be balanced and unbalanced universal conversion.
This transformer can be used for passive front stage, single-ended to single-ended, single-ended to balanced, balanced to single-ended, etc., balanced to balanced, etc., the wiring is as shown below.

For the 600Ω output impedance of audio sources such as CDs, mixers, mobile phones, computers, and digital players, the design process has been improved in terms of performance to broaden the frequency response and enhance the effect.
The sound of the EI transformer is thick, rich, warm and mellow. When the fever winding method is used, it is not inferior in details and resolution. The high-frequency fine extension is also very good, and the tone is different from Permo Alloy signal transformer.
