The term "return" on audio equipment refers to the process of sending audio signals back to the source or another device for various purposes. This can include feedback reduction, signal routing, or signal processing adjustments. In the context of audio systems, returns are crucial for maintaining signal integrity and preventing unwanted noise or distortion.

Returns are particularly important in professional audio setups, where they are used to manage feedback, which can occur when a microphone picks up the amplified sound from a speaker, creating an echo-like effect. By using returns, sound engineers can isolate the signal from the speaker and adjust it before re-introducing it to the system, effectively reducing feedback.

According to a study by the Audio Engineering Society, feedback in audio systems can lead to a significant decrease in sound quality and can even cause equipment damage. The use of returns in audio equipment helps mitigate these issues by allowing for precise control over the signal path.

Data from the National Association of Music Merchants (NAMM) indicates that feedback is one of the most common problems faced by sound engineers and performers. In a survey of professional sound technicians, 85% reported that feedback is a frequent issue in live performances. The use of returns in audio equipment is a standard practice to address this problem and ensure a high-quality audio experience.
