6.0 E-4 System Setup
6.3 System setup procedure
The first time you turn on an E-4 system it loads its factory
(default) configuration settings. These settings were stored in the
E-4 when it was manufactured. Once your PC is fully connected
to the E-4 system, you can use the
Installer
™ software to make
changes to the factory configuration settings.
The configuration contains the “start-up” settings for the E-4
hardware. Once your work is completed and saved to the E-4
hardware, the new settings become the startup configuration.

Set the maximum output gain.
This sets the maximum allowed volume within a zone. Play a
source that will be used in that zone and raise the volume
slider to the zero level. If it is too loud, lower the maximum
gain stop.
Programmer’s Note:
If the source still plays too loud at
the –30 dB setting, you should lower the tap setting on
your speakers for optimal system performance.
