Signal isolation: The most important function of an audio isolator is to isolate audio signals from each other. This is usually accomplished through the use of transformers.
^^ 2 Ground lift: An audio isolator may also include a ground lift feature, which separates the ground connection between two devices to eliminate hum and other ground loop issues.
^^ 3 Input/Output Impedance: Audio isolators often have adjustable input and output impedance, allowing them to match the impedance of different audio equipment.
^^ 4Low noise: Audio isolators should have low noise levels to minimize the introduction of unwanted noise into the audio signal.
^^ 5 Sturdy construction: Audio isolators should be built with high-quality components and sturdy construction to withstand the demands of professional audio applications.
Portability: Some audio isolators are designed for portability, making them ideal for live sound reinforcement, broadcast, and recording applications.
