1.0 Safety Information

WARNING

To reduce the risk of fire or electric shock, do not expose this system to rain or moisture.

CAUTION

To reduce the risk of electrical shock, do not remove the cover of the FreeSpace®system

controller (Model 8/32). There are no user-serviceable parts inside. Refer servicing to

qualified personnel. The CAUTION marks described here appear on the top of the

controller.

The lightning flash with arrowhead symbol, within an equilateral triangle, alerts

the user to the presence of uninsulated “dangerous voltage” within the system

enclosure. This voltage may be sufficient to constitute a risk of electrical shock.

The exclamation point, within an equilateral triangle, alerts the user to the

presence of important operating instructions in this guide.

WARNING

The Bose®FreeSpace system controller (Model 8/32) is an electrical appliance. There are no

user-serviceable parts inside. As with all electrical appliances, dangerous electrical shock

may result if repair is attempted by unqualified personnel. Service and the installation of any

optional electronics should always be performed by Bose-authorized personnel.

RISK OF ELECTRICAL SHOCK—DO NOT OPEN

TO PREVENT ELECTRICAL SHOCK, DO NOT REMOVE

COVER. NO USER-SERVICEABLE PARTS INSIDE.

REFER SERVICING TO QUALIFIED PERSONNEL.

TO PREVENT FIRE OR SHOCK HAZARD, DO NOT

EXPOSE THIS UNIT TO RAIN OR MOISTURE.

1.0 Safety Information

Please read this safety information before installing, connecting, or operating the Bose®

FreeSpace®system controller (Model 8/32).

1.1 Read the instructions – Read and keep all safety and operating instructions.

1.2 Follow cautions – For safety, follow all cautions and warnings in this guide and on

the system controller.

1.3 Avoid moisture – Do not install the controller near water or excessive humidity. Do

not install near swimming pools, spas, dish washing or laundry equipment, or in

other excessively humid environments.

1.4 Avoid heat – Do not install the controller near excessive heat sources, such as

radiators, ranges, grills, fryers, stoves, or other appliances.

1.5 Protect cables – Put cables where they won’t be pinched or cut by heavy or sharp

objects.

1.6 Connect the power cord properly – Make sure the controller is properly grounded.

If the power cord includes a ground pin, it should be connected to the ground on the

power outlet.

1.7 Disconnect for service – To reduce the risk of electric shock, disconnect the power

cord before replacing the fuse or when changing the voltage selection. The power

cord must remain disconnected until the fuse holder/voltage selector assembly is

replaced.

1.8 Ventilate equipment racks – If mounting the controller in a rack with heat-produc-

ing electronic equipment, vent the rear of the rack to prevent overheating the

controller.

1.9 If damage occurs – Obtain service from qualified service personnel under the

following conditions:

A. Water or other liquid spills into the controller;

B. If the controller is exposed to rain or water;

C. If the controller does not operate normally, even though you have followed the

instructions in this guide;

D. If the controller exhibits a distinct change in performance.

1.10 Safety check – After service or repairs, ask the service technician to perform safety

checks. This includes properly connecting the safety ground wire to the power

mains connector.

2.0 Introduction

The Bose®FreeSpace®system controller (Model 8/32) works with Bose FreeSpace Model

8, Model 25, Model 32, and the Bose 102®loudspeakers to provide a highly flexible, multi-

zone music and paging system. It features three source channels (two music, one paging)

with Bose active equalization. Bose Opti-voice®circuitry gradually mutes music before

paging, then returns music volume to the previous level. Both output channels provide

equalized and unequalized output to simultaneously power the FreeSpace Model 8 and

Model 32, Model 25, or Bose 102 loudspeakers, or another system, like the Bose

FreeSpace®business music system.

All Bose FreeSpace Model 8, Model 32, Model 25, and Bose 102 loudspeakers, except

the 4ΩModel 32 and the 4ΩModel 25, require a Bose approved equalizer, such as this

controller. Using the loudspeakers without an approved equalizer causes inferior acoustic

performance and may damage the loudspeakers. This controller is the only equalizer

approved for use with the FreeSpace Model 8 or Model 32 loudspeakers in fire protective

signaling and warning systems (see Section B.2, “Fire protective signaling”).

2.1 Unpacking the controller

Carefully unpack the controller (Figure 1). Save the carton and packaging. If the controller

appears damaged, do not try to use it. Return it to its original carton and immediately

notify the Bose Service Department or your authorized Bose Professional Products dealer.

4.0 Installation

4.1 Electrical connections

Although the FreeSpace®system controller accepts balanced and unbalanced sources,

balanced sources provide better audio performance. Observe proper polarity when

making connections:

• The positive terminal is usually the high, tip, or plus (+) terminal, or pin 2.

• The negative terminal is usually the low, ring, or minus (–) terminal, or pin 3.

• The ground terminal is usually the shield, sleeve, or ground ( ) terminal, or pin 1.

Note: The ground terminals are NOT safety grounds. They are for audio signals only. Do

not use these terminals as a substitute for a proper safety (earth) ground for this equip-

ment or other equipment connected to it.

From microphone or paging source

(Figure 6):

1. Connect the positive and negative terminals to the positive and negative terminals on

the controller.

2a. If the source has balanced outputs, connect the ground terminal to the ground

terminal on the controller.

2b. If the source has unbalanced outputs, connect the ground terminal on the controller

to the negative terminal on the controller. This will help prevent unwanted noise.

CAUTION

Unplug all components before

making connections.

4.0 Installation

From music source:

1. Connect the positive and negative terminals to the positive and negative terminals on

the controller.

2a. If the source has balanced outputs (Figure 7), connect the ground terminal to the

ground terminal on the controller.

2b. If the source has unbalanced outputs (Figure 8), connect the ground terminal on the

controller to the negative terminal on the controller. This will help prevent unwanted

noise.
