 4400 System Setup
6.3 System setup procedure
The first time you turn on a FreeSpace 4400 system it loads its 
factory (default) configuration settings. These settings were 
stored in the FreeSpace 4400 when it was manufactured. Once 
your PC is fully connected to the FreeSpace 4400 system, you 
can use the FreeSpace 4400 Installer™ software to make 
changes to the factory configuration settings.
The configuration contains the “start-up” settings for the 
FreeSpace 4400 system. Once your work is completed and 
flashed to the FreeSpace 4400 hardware, the new settings 
become the startup configuration.
1.
Select Output Gain for each zone and mute the output. This 
prevents any damage to loudspeakers during this proce-
dure. This also allows you to work without disturbing any 
other people in your work area. See “Output gain” on this 
page.
2.
Set up the ZONE for each output channel. Choose a 
Speaker EQ (default is No EQ) for the speakers you are 
using. You can use the Subzones table to document your 
subzones. See “Zone setup” on page 36.
3.
Set up the Input Gain controls for each source. Choose set-
tings for input type, gain, and source leveling. If the input 
type is set for microphone use, you can turn phantom power 
(+12V) on or off. See “Input gain” on page 37.
4.
Set up the Output Gain controls for each zone. Set the min-
imum/maximum gain (volume) limits and the initial gain level. 
See “Output gain” on this page.
5.
Select Source Assign for each zone and assign sources for 
each. See “Source assign” on page 39.
6.
Set up the source EQ for AUX MIC/LINE 3 and 
 
PAGE/MIC/LINE 4 inputs. See “Source EQ” on page 40.
7.
Select Page Set Up. See “Page setup” on page 40.
8.
Select EQ for each zone. See “Zone EQ” on page 42.
9.
Select the Dynamic EQ state for each zone. See “Dynamic 
EQ” on page 43.
10. Set up Auto Volume. See “Auto Volume” on page 43.
11. Create a System Schedule. See the “Set Up Schedule 
12. Click the flash configuration button in the upper toolbox. You 
will be asked to confirm that you want to save the configura-
tion to the FreeSpace 4400 hardware. Once you confirm, the 
configuration and scheduling settings are sent to the 
FreeSpace 4400 system. 
 
A copy of the FreeSpace 4400 Installer™ software design file 
is also sent to the hardware.
6.3.1 Output gain
The controls in the Output Gain control panel allow you to control

1.
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 loudspeakers for optimal system performance.
