What Is the EQ Guide for IEMs Website?
Updated
The EQ Guide for IEMs (iem-eq-guide.pages.dev) is a free online reference for equalizing in-ear monitors, written for everyone from beginners to experienced users. It is a reading resource, not a shop or an EQ tool: you navigate it through a table of contents and work through the material at your own pace. It suits you if you want practical, in-depth guidance on how to EQ IEMs and are willing to put in active effort — the guide states plainly that it is long and not meant to be an easy read.
What the guide covers
The site is organized into seven main sections, plus two supporting pages:
| Section | What it contains |
|---|---|
| Audio & EQ Basics | Foundational knowledge, summarized |
| How to EQ | Detailed instructions and information on the EQ process |
| Case Studies | Demonstrations of EQ in different contexts |
| Rigs, Curves, & Targets | Information on metrology and preference testing |
| Measurement Databases | Examination of relevant and popular measurement databases |
| Myths & Misconceptions | Common mistaken assumptions, examined and debunked |
| Additional Tools | Other EQ/measurement tools, with instructions |
| Changelog | Every change, recorded daily |
| FAQ/Contact | Common questions and contact information |
For readers with a theoretical or academic bent, the guide also hosts a collection of AES papers related to IEMs.
How to use it
There is no required reading order. The guide recommends opening whichever section you want or need as you progress, using the left-hand table of contents for main sections and the secondary one on the right of each page for specific topics.
Two practical notes before you start:
- Some background helps. The guide summarizes basic theory, but says a general understanding of the hearing system, audio, and waves is useful.
- A shorter alternative exists. If you want a quick introduction without the detail, the guide points to a condensed version available through squig.link databases in the Equalizer tab — the yellow question mark button there presents a small chunk of this guide's content in compact form, suitable for most people who just want to get started.
Is it the right resource for you?
Choose the full guide if you want comprehensive, step-by-step instruction and are prepared to read actively. Choose the squig.link condensed version if you only need a quick primer. If you are looking to buy IEMs or run an EQ tool directly, this site is neither — it is the reference you read alongside those activities.
