Freespace system InstallerTM software, included with each unit, makes it easy to configure and service the E-4 system.
With capacity for four source inputs, including two Line In, one Mic/Line and one Page/Mic/Line, the E-4 system provides the inputs needed for most business music installations.
Its proprietary power-sharing amplifier dynamically shares 400 watts across 4 output channels ranging from as low as 1W to as high as 400W. For example, if you have a two-zone system that requires 5 watts in Zone 1 and 395 watts in Zone 2, the FreeSpace E-4 system distributes the power based on those needs.
As a single component, the E-4 provides the processing and control features required for one-to-four zone business music applications. These features include:
-
Auto Volume: Offers dynamic control of individual zone volume levels to compensate for changes in background noise level. Auto Volume requires the use of the FreeSpace E-4 System Auto Volume Mic Kit.
-
Scheduling: Allows programming of the E-4 system for automated on/ off, volume, and source changes according to time of day or day of week.
-
Opti-Voice® paging: Provides the appropriate sound level regardless of variations in speech projection.
-
Source Leveling: Automates system compensation for variations in source input levels.
-
Dynamic Equalization: Maintains tonal balance at all listening levels.
-
Music on Hold: Provides an output for simple integration into a phone system.
-
Room Equalization: Provides easy adjustment of tonal balance in each zone.
-
Limiting: Protects loudspeakers from unwanted transient power loads.
-
Signal Routing: Allows for an input source to be routed to any of the four amplifier outputs.
