6.0 E4 System Setup
IMPORTANT: Before you calibrate
Auto Volume
Make sure that the system hardware installation is complete
and that all components (sense microphones, speakers, and
Auto Volume user interfaces) are properly connected. Remem-
ber that speakers must be directly wired to the ZONE OUT
connectors on the E4 rear panel.
Make sure that you have selected the correct speaker model in
the ZONE setup pane.
Make sure that the output gain is set so that the source can be
heard without dropping out.
Check that sources have been assigned to zones.
Programmer’s Note: If a source is routed to multiple
zones, you need to perform Auto Volume calibration on
that source only once. After calibration, the source is
“locked” (no adjustments to the source will be allowed)
until all zones using that source have been reset.
Check the EQ pane and make any final adjustments.
DO NOT USE AUTOTRANSFORMERS: Speakers must be
directly wired to the ZONE OUT connector of the E4 hardware.
DO NOT use an autotransformer on the speaker line to adjust
the speaker volume. If you lower the volume using an
autotransformer, the E4 system will raise the volume. Likewise,
if you raise the volume using an autotransformer, the E4 sys-
tem will lower the volume.
Auto Volume setup procedure
Programmer’s Note: While the Auto Volume calibra-
tion is running,
DO NOT use the paging microphone.
Wait for the Auto Volume calibration to finish before

unit.
