4400 Introduction

1.1 The Bose

FreeSpace

4400

Business Music System

The FreeSpace

4400 system is an integrated four-channel digital

signal processor and 400-watt power amplifier for 70/100V busi

ness music applications.

The FreeSpace 4400 system has a total of four source inputs,

including two Line In, one Mic/Line and one Page/Mic/Line, to

provide the inputs needed for most business music installations.

The system also has a direct input which can override the

sources playing on all four output channels.

The FreeSpace 4400 system has four amplifier output channels

which can be configured for different zones. A Music on Hold out

put is also provided for simple integration into a phone system.

In a single chassis, it provides all of the processing and control

features required for one-to-four zone business music applica-

tions. These features include:

• Auto Volume: When used with the optional FreeSpace system

Auto Volume Sense Mic, FreeSpace 4400 system electronics

dynamically control the program level in each zone so your cus

tomers can always hear it, regardless of the background noise.

• Scheduling: Allows you to program the FreeSpace 4400 sys-

tem electronics for automated on/off control, source changes,

and volume changes according to time of day or day of week.

• Multi-Zone Paging: Allows you to initiate a page from a single

keypad to one or more of the zones being powered by the

same FreeSpace 4400 system.

• Opti-voice

Paging: Provides a smooth transition between

music and page signals.

• Opti-source

Input Leveling: Monitors the input level of up to

four sources and continually makes adjustments to maintain a

consistent volume level between different sources.

• Dynamic Equalization: Maintains tonal balance at all listening

levels.

• Room Equalization: Provides easy adjustment of tonal bal-

ance in each zone.

• Signal Routing: Meets the demands of most four-zone sys-

tems, allowing for an input source to be routed to any of the

four amplifier outputs.

• Serial Data Interface: RS-232 serial port for easy interfacing

to your PC

• Remote On/Off Input: Accepts a remote STANDBY switch

The integrated 400-watt power amplifier features a patented

power-sharing technology which dynamically allocates power to

each output.

For example, if you have a two-zone system that requires 5 watts

in Zone 1 and 395 watts in Zone 2, the FreeSpace 4400 system

electronics distributes the power based on those needs.

The FreeSpace 4400 system also includes an easy-to-replace

memory module, which holds the system configuration settings

and design file uploaded by the FreeSpace 4400 Installer™

software

(see page 3).
