120*93mm Audio Isolator Module Eliminating Noise in Power Amplifiers 20-20KHZ

1.Product Description

120*93mm Audio isolator is a device used for audio signal processing. It mainly uses electromagnetic induction or other isolation techniques to maintain the integrity of audio signals while achieving electrical isolation between input and output circuits, avoiding signal interference and ground loop problems. Its basic structure usually includes one or more transformers, which use electromagnetic coupling between transformer windings to transmit audio signals while preventing direct current and low-frequency common mode signals from passing through.

2.Function

1. Noise cancellation: Eliminate noise caused by ground loops, electromagnetic interference, etc., and improve the purity of audio signals. In live performances, multiple audio devices are connected together, and the ground loop can easily produce low-frequency humming sounds. Audio isolators effectively remove this noise by isolating the ground connection, allowing the audience to hear clear sound.

2. Signal isolation and protection: Protect audio equipment from current surges caused by poor grounding or other electrical faults. For example, when a device experiences a short circuit fault, an audio isolator can prevent the fault current from conducting to other devices, reducing the risk of equipment damage.

3. Balance imbalance conversion: Some audio isolators have the function of converting balanced and unbalanced audio signals. Balanced signals have a long transmission distance and strong anti-interference ability, while unbalanced signals are commonly used in some consumer grade devices. Audio isolators can convert between balanced and unbalanced signals according to actual needs, facilitating connections and signal transmission between different devices.

4. Level adjustment: Some audio isolators can also fine tune the level of audio signals to match the input and output level requirements of different devices. For example, increasing the low-level microphone signal appropriately so that it can be better processed by subsequent amplifiers.
