lengthy experience in performance car audio design combined with the legendary engineering
skills of Robert Zeff and the staff at Nikola Engineering. You are now the proud owner of the long
anticipated DXE, A unique combination of the highest quality analog EQ-crossover and precision
digital control we call Digital Hybrid. Whether you are a competitor or simply enjoy faithfully
reproduced music, you will definitely appreciate how the DXE makes your system sound.
This component isn’t the easiest to understand and use. It requires a good understanding of
audio and the terms and language used to describe it. You don’t have to be a genius but a bit of
experience and common sense will go a long way.
This manual is written in two partsInstallation and Configuration/Tuning. Before you begin find
and complete the “System Configuration Worksheet” (make a bunch of copies) included in this
manual. Carefully design your system and decide on your basic crossover points. This will give
you a good starting point and a reference to return to when you begin final tuning. If at any point
you begin to feel overwhelmed, return to your local Arc Audio dealer and let the trained
professionals install or tune it for you.
