1.Audio signal conversion:
The 12:1 Permalloy Audio Transformer is capable of transforming audio signals, i.e., converting signals from one level to another. Its 12:1 ratio sequence is suitable for applications that require greater level conversion, such as boosting from low to high level signals.
The transformer's wide frequency response (20 Hz - 20 kHz) ensures that it can handle a wide range of audio signals from low to high frequencies with guaranteed signal accuracy.
2. Connectors:
12:1 Permalloy Audio Transformer Through its 12:1 impedance ratio, the Permalloy Audio Transformer enables effective impedance matching for optimal energy transfer between the signal source and the receiving device. This is extremely important between audio devices in a hi-fi audio system, especially in amplifiers, sound equipment and audio processing units.
By matching the impedance properly, signal reflection and scavenging can be avoided and the overall performance of the system can be improved.
3. Electrical isolation:
The 12:1 Permalloy Audio Transformer provides excellent electrical isolation, enabling the direct electrical connection between the audio signal source and the audio receiving equipment to be isolated, avoiding ground loop noise and electrical interference. It effectively reduces noise interference caused by current and protects audio equipment from the effects of electrical faults or sudden voltage fluctuations.
Isolation performance for high-quality audio transmission, especially in complex audio systems, it can ensure the sound quality and stability of signal transmission.
