6.0 FreeSpace ® 4400 System Setup
IMPORTANT: Before you calibrate
Auto Volume
• Make sure that the system hardware installation is complete
and that all components (sense microphones, loudspeakers,
and AVM (Auto Volume) user interfaces) are properly con-
nected. Remember that loudspeakers must be directly wired to
the ZONE OUTPUT connectors on the FreeSpace 4400 rear
panel.
• Make sure that you have selected the correct loudspeaker
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: Loudspeakers must
be directly wired to the ZONE OUTPUT connector of the
FreeSpace 4400 hardware. DO NOT use an autotransformer on
the loudspeaker line to adjust the loudspeaker volume. If you
lower the volume using an autotransformer, the FreeSpace
4400 system will raise the volume. Likewise, if you raise the
volume using an autotransformer, the FreeSpace 4400 system
will lower the volume.
Auto Volume setup procedure

FreeSpace 4400 system.
