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.
