Introduction
Thank you for your purchase of Echo Mountain Audio’s charge - coupled crossover boards for the
JBL Model 4425 Studio Monitor. The set of bare boards you have received are intended for DIY
build and “plug
- and - play” integration into your existing 4425 monitor system.
The scope of this user manual is to, as succinctly as possible, guide the assembly of the PCBs
and integration into the existing crossover unit.
Any comments, questions, technical support requests, etc. are welcomed and encouraged, and
