ZXY2207 10K:600 Audio Isolator High Reducibility Audio Common Ground Isolator

1.Product Description

10K: 600 Audio Isolator refers to an audio isolator with a conversion ratio of 10K (10000 ohms) to 600 ohms, mainly used for audio signal processing, achieving electrical isolation while maintaining audio signal integrity. The following introduces the specifications, working principles, characteristics, and application scenarios:

1.10K and 600: These two numbers represent the impedance values of the primary and secondary of the audio isolator. 10K (10000 ohms) is usually the impedance of the primary winding, while 600 ohms is the impedance of the secondary winding. This specific impedance ratio design enables audio isolators to achieve good matching between audio devices with different impedance characteristics, ensuring efficient transmission and optimal performance of audio signals.

2. Impedance matching function: In audio systems, the impedance of source devices (such as microphones and audio players) and load devices (such as amplifiers and speakers) need to be matched with each other to achieve maximum power transmission and minimum signal reflection. A 10K:600 impedance ratio helps connect high impedance audio sources to low impedance loads, or vice versa, optimizing the transmission of audio signals between different devices, reducing signal loss and distortion.

2.Working Principle

10K: 600 Audio Isolator mainly works based on the principles of electromagnetic induction and impedance transformation, as follows:

1. Electromagnetic induction principle - primary winding generates magnetic field/secondary winding generates induced electromotive force/electrical isolation implementation

2. Impedance transformation principle
--Impedance matching function: The impedance ratio of 10K:600 determines the matching function of the audio isolator between different impedance devices. In an audio system, the impedance of the source and load devices needs to be matched to achieve maximum power transmission and minimum signal reflection. When a high impedance audio source is connected to the 10K primary winding of a 10K:600 Audio Isolator, electromagnetic induction is used to output signals in the 600 ohm secondary winding, which can be adapted to low impedance load devices, and vice versa, thereby optimizing the transmission of audio signals between different devices and reducing signal loss and distortion.

--Signal transmission optimization: According to Ohm's law, the relationship between voltage and current will change under different impedance environments. The audio isolator adjusts the voltage and current ratio of the signal through a specific impedance ratio, enabling the audio signal to better adapt to the input and output requirements of different devices during transmission, ensuring that the amplitude, frequency response, phase and other characteristics of the signal are not significantly affected during transmission, and maintaining the integrity of the audio signal.
