We’ve published a new staff blog explaining the fundamentals of EQ (equalization), an essential tool for PA systems, live performances, recording, and streaming.
The article covers the basic role of EQ, the characteristics of each frequency range, how to use a high-pass filter (HPF/low cut) effectively, and the fundamental concepts of shaping your sound. It also explains the differences between parametric EQ (PEQ) and graphic EQ (GEQ), along with practical techniques for preventing feedback, all in an easy-to-understand format for beginners.
Whether you’re just getting started with live sound or recording, or simply want to refresh your knowledge of EQ, this guide is a great place to begin.
