What is “Hi-Z”?

Hi-Z (High Impedance)

In the audio industry, “Z” is the abbreviation for impedance. Hi-Z refers to “high impedance,” which pertains to the input or output impedance of a device. Devices with impedances of several thousand ohms and up are considered high impedance.

A typical guitar without an active pickup installed or a direct box (DI) connected generally needs to be connected to a Hi-Z input. Otherwise, the electronics will be “loaded down,” significantly altering the sound.
