What is an Insert (Console)?

An insert on an audio console is a connection point that allows an external audio processor to be placed directly into the signal path of a channel. This lets the signal pass out of the console, through an external device, and then return to the same channel for further processing.

Insert points are commonly used with devices such as compressors, equalizers, noise gates, and other dynamic processors. Because the signal is fully routed through the external device, the effect processes the entire audio signal rather than blending with it.

On mixing consoles, inserts are typically located after the preamplifier stage and before the channel fader or EQ section, depending on the console design. They provide a convenient way to integrate outboard gear into the signal chain during recording or live sound mixing.
