1.0 System Placement

1.1 System electronics

Note: Do not mount the system electronics within a plenum space or any place it cannot be seen during operation.

English

Be sure the electrical system the FreeSpace® 6 system will be connected to has the correct voltage, frequency,
power cord, and agency approvals for the area. In North America, the system should have UL listing or CSA certifica­tion labeling.

The system electronics can be mounted on a wall or placed on a shelf.

• Wall construction and material must be sturdy enough to support the system electronics weight of 11 lb (5 kg).

Bose® is not responsible for system electronics mounted in or on unsuitable surfaces.

• Be sure the selected spot is safe for drilling. Avoid surfaces that could conceal hazards like electrical conduits or

plumbing.

• Do not put the system electronics directly above intense heat sources such as radiators, space heaters, or other

amplification equipment.

• Do not put the system electronics in environments with temperatures exceeding 100°F (40°C).

If the system electronics is in an enclosed space, allow at least 2 inches (5 cm) clearance on the top and the sides. If
the system electronics is on an open surface, keep the cooling slots unobstructed.

Discuss the placement of the system electronics and the remote control with the business owner. It should be placed
where it is easily accessible by business personnel, but not accessible by patrons.

Warranty

Bose® warrants the FreeSpace® 6 business music system with a 5-year, transferable, limited warranty. For more
information, please read the warranty card.

Service

If you have problems with your Bose FreeSpace 6 business music system, contact your authorized Bose Profes­sional Products Dealer. The dealer will verify any defects and arrange for service by a factory authorized Bose service
agency, or by Bose Corporation.

The front edge should be no more than 1 inch (25.4 mm) from the opening. Leave the opening uncovered.

Note: Do not place anything in the space that blocks the ventilation slots or adds heat.

1.2 Remote control

The remote control should be wall mounted in an electrical box (not included) similar to a light-switch electrical box.
Install the control where day-to-day adjustments will be easy to make.

1.3 Loudspeakers

The loudspeakers can be mounted to most fixed or suspended ceilings or walls strong enough to support the
combined weight of the hardware and loudspeakers. Bose® will not be responsible for brackets or loudspeakers
mounted in unsuitable places.

Permanent ceilings (gypsum board or plaster) may conceal electrical conduits or other hazards. Check for these
hazards before cutting mounting holes, especially if using power equipment.

These loudspeakers are UL listed as vandal resistant and will resist malicious damage from a sharp object.
However, they can be removed, or damaged with blows from a heavy object. If vandalism is a concern,
consider mounting the loudspeakers out of reach.

1.3.1 Clearance

Allow enough clearance for both the depth of the ceiling loudspeaker and the wire from the electrical fitting. To
decrease this distance, an angled electrical fitting may have to be used if flexible metallic conduit or flexible metallic
tubing is used.

1.0 System Placement

1.3.2 Flush-mount loudspeaker placement

It is important to take a few minutes before installing the system to determine loudspeaker placement. The placement
of these loudspeakers is dependent upon the following factors:

English

• Ceiling height

• Listener ear height

• Desired smoothness of coverage

• Ceiling type (see Section 1.4)

Proper loudspeaker placement provides enjoyable sound no matter where you are in the area. Follow these steps to
determine the proper loudspeaker placement locations.

1. Begin by estimating the maximum ear height of the listener. For example, in a retail environment, patrons will most

likely be standing. Maximum ear height in this case will probably be about 6 feet. In a restaurant, patrons will be
seated and ear height may be 4 feet.

Note: The shorter the ear height, the broader the sound beam area. This means that the loudspeakers are placed

farther apart. Conversely, the higher the ear height, the narrower the sound beam area. The loudspeakers are placed
closer together.

Beamwidth

height (H)

Ear

height

2. Create a floor plan sketch of the installation site. Use the following formulas and table to determine loudspeaker

placement.

Use this formula to determine loudspeaker beamwidth height (H).

ceiling height - ear height = loudspeaker beamwidth height (H)

In this example, the room is 36 feet (11 m) x 36 feet (11 m) with a 10 foot (3 m) ceiling.

10 feet (3 m) - 4 feet (1.2 m) = 6 feet (1.8 m)

1.0 System Placement

Use the following table to help calculate the ideal starting distance from adjacent walls and the distance between
each adjacent loudspeaker. Multiplier A is for vertical and horizontal spacing. In order to cover a large area, wider

variances in coverage may be acceptable. For our example, a direct field variance of ±6.0dB is desired. That corre-

sponds to a multiplier of 3.0.

Multipliers for FreeSpace

more than ±3dB of reverberant field coverage, the industry standard.

Calculate the loudspeaker placement for this installation.

For placement of loudspeakers from a wall, multiply 1/2A x H. In our example, 1.5 x 6 feet = 9 feet.

For placement of loudspeakers from each other, multiply A x H. In our example, 3 x 6 feet = 18 feet.

So in our example, the loudspeakers will be placed at the 9 foot mark from each wall. This gives an 18 foot distance
between each loudspeaker. Be aware that not all installations will lend themselves easily to the formulas but the
formulas can be a great aid in determining loudspeaker placement. Your experience and judgement will be an
invaluable asset in determining loudspeaker placement.

®

6 loudspeaker spacings are shown up to ±6dB direct field coverage. This spacing yields no

Direct Field Variance ±1.5dB ±3.0dB ±6.0dB

Multiplier A 2.0 2.3 3.0

English

Note: The loudspeaker layout should be centered in the room so the distance between the loudspeakers at the edge
of the layout and the perimeter walls is fairly uniform. If necessary, shift the entire loudspeaker layout to ensure a
consistent border. DO NOT install loudspeakers less than 31/2 feet (1 meter) from any wall. Doing so causes a reduc­tion in bass due to the proximity of the wall.

1.3.3 Surface-mount loudspeaker placement

Determining where to place surface-mount loudspeakers is easy. Using your floor plan (which is drawn to scale),
draw 25 foot (7.5 m) spacing circles to determine loudspeaker placement.

English

If your floor plan
scale dimension is...

1

⁄16 inch (.16 cm) 19⁄16 inch (4 cm)

1

⁄8 inch (.31 cm) 31⁄8 inch (8 cm)

1

⁄4 inch (.63 cm) 61⁄4 inch (16 cm)

Then your spacing circle
diameter size is...

Note: The surface-mount loudspeakers have a throw distance of 25 feet (8 m). For effective coverage only 80% of the
area need be covered. The spacing circles should just touch each other or overlap slightly.

Follow these simple rules when laying out the loudspeakers.

• The spacing circles can be drawn with a compass.

• Place a symbol on your floor plan identifying the location of the loudspeaker.

• Start in the corners, if possible, for maximum coverage and bass response.

• Because additions and/or cancellations occur from walls, do not space the loudspeaker equidistant from a side

wall and the ceiling. In other words, do not place the loudspeaker 3.5 feet (1 m) from the side wall and 3.5 feet
(1 m) from the ceiling.

• In a square room, place each loudspeaker slightly off center.

• The maximum height for the loudspeakers should be 12 feet (4 m) from the floor.

For technical assistance, call 1-800-994-2673 in the USA or your local Bose® distributor.

1.0 System Placement

1.4 Ceiling types

Check the ceiling construction before beginning installation. Ceiling type, thickness, and strength determine the
installation and connection methods for the loudspeakers. Ceiling type also dictates whether to use support rails. If in

English

doubt about these choices, consult a building trade professional, architect, or licensed professional engineer.

Ceiling Type Description

Rigid ceiling tiles If the tiles are particle board, plywood, gypsum board, or plaster, follow the instructions for

either tile ceilings or structural ceilings. They do not require support rails. However, support

rails may be needed if moisture or other environmental conditions could weaken the ceiling.

However, if the support rails are not used, the tilesmust be strong enough to support the
loudspeaker by themselves. See “Support rails” below for more information.

Soft ceiling tiles If the tiles are a “soft” material (like mineral wool or glass fiber), follow the instructions for

ceiling tiles. Use the support rails with this type of ceiling tile. These tiles can bow or absorb
moisture and may not continue to support the loudspeaker’s weight.

Structural ceilings Follow the instructions for structural ceilings. Remove the support rails from the ceiling pans

before using the “structural ceiling” installation method.

Support rails

Not all ceilings require support rails. Only the installer can determine if a ceiling is strong enough to support the
loudspeakers by itself. If in doubt, consult a building trade professional, architect, or licensed professional engineer.

The support rails are 233/4 inches (60 cm) long, and will support a loudspeaker on a 2 foot x 4 foot (0.6 m x 1.2 m) or
smaller tile. If the ceiling tiles are another size, the support rails will usually provide adequate support if they meet the
edge of the tile on at least two sides.

Follow these guidelines:

• For 60 cm tiles, place the ceiling pans and support rails at a 10° – 15° angle

• For 62 cm tiles, extend the rails in opposite directions until each rail reaches the ceiling grid on one side of the tile

WARNING

The springs are ready to use. Unhooking them, except as described in this guide, may cause personal injury. Always
wear safety glasses when installing loudspeakers.

CAUTION

If in doubt about the proper wire or connecting to the source or system electronics, have an audio profesional
complete the electrical connections.

CAUTION

Unplug all system components from electrical outlets before making connections.

2.1.1 Loudspeaker installation in a ceiling tile

• Do not unhook the springs.

• Cut a 53/4 inch (145 mm) hole for the loudspeaker. Use the loudspeaker box as a template to cut the correct hole

size.

2.2 Flush-mount loudspeaker enclosures

Note: If the electrical connections have not yet been made, pull all wires through the mounting hole and clear of the
springs.

Complete electrical connections before releasing the loudspeaker into the ceiling. Releasing the loudspeaker with
wires unconnected could cause the loudspeaker to jam on the dangling wires or damage the mounting hole or the
loudspeaker rim.

If the springs are to support the loudspeaker while making the electrical connections, complete Steps 1 and 2 only in
Section 2.1.2. Once the loudspeaker is hooked on the springs, continue with Section 2.3.4, “Rotation feature” and
Section 2.3, “Electrical connections,” then return to Step 3 of this section.

Note: Do not remove the protective shield from the loudspeaker until it is time to install the loudspeaker grille. The
loudspeaker grille may be installed when it is felt that subsequent installation steps or construction activities are not
likely to result in grille damage.

2.6 Installing a surface-mount loudspeaker

Wall construction and material must be sturdy enough to support the loudspeaker weight of 21/2 lb (1.2 kg). Bose® is
not responsible for loudspeakers mounted in or on unsuitable surfaces.

The type and length of fastener depends upon the mounting surface selected. To mount to hollow gypsum board or
plaster wall, use wall anchors with a load rating in shear of at least 25 pounds PER FASTENER. Direct attachment to
more substantial material also should meet this criteria.

2.9.1 Wall mounting

WARNING

Do not use the system electronics as a drill guide; personal injury could result. Be sure to observe all other safety
precautions while drilling or installing the mounting hardware.

Attach the system electronics to a vertical surface using at least four of the ten mounting holes. In the U.S., #10 sheet
metal or machine screws, or 3/16 inch diameter wood screws (or 4 mm diameter metric screws) will work with the
“keyhole” mounting holes.

The type and length of fastener depends upon the mounting surface selected. To mount to hollow gypsum board or
plaster wall, use wall anchors with a load rating in shear of at least 25 pounds PER FASTENER. Direct attachment to
more substantial material also should meet this criteria. The keyholes make it easy to pre-install the fasteners before
mounting. For security from accidental or rapid removal of the system electronics, use washers under the screw
heads. This prevents using the keyhole feature. The two additional round holes may be used for the same purpose.

Recommendation:

additional holes allow you to mount the system electronics securely.

Bose® recommends using at least one fastener at each of the four corners of the product. The

2.9.2 Shelf mounting

1. If mounting in an audio equipment rack, use a shelf designed for rack systems. If the shelf is above other sources
of heat such as amplifiers, use a solid material shelf not a perforated material shelf.

Note: DO NOT attach a rack panel to the front of the system box to mount it in a rack.

2. Maintain the 2 inch (50 mm) clearance recommendations when stacking electronic equipment above or below
the system electronics.

3. To prevent accidental dislodging of the system box, use at least two mounting screws to attach the system to
the shelf surface.

4. Use cable ties or other forms of strain relief on the signal and loudspeaker cables to prevent excessive mechani­cal stress on the wire connections.

5. Allow enough cable slack to move the system electronics forward if adjusting the controls is needed.

6. Dress the wiring so that no one can accidentally trip over it.

2.9.3 Connections

Note: To prevent excessive mechanical stress on the wire connections, use cable ties or other strain relief for the

signal and loudspeaker cables.

English

If using a push-to-talk microphone, be sure the push-to-talk switch is properly wired so that it places a short circuit
across the microphone output except when the user presses the switch.

CAUTION

Improper connection can damage both the source equipment and the FreeSpace® 6 system. Be sure to review this
guide for information on nominal output voltage, output impedance, and balanced and unbalanced outputs.

Note: Sources are either balanced or unbalanced. Call 1-800-288-2673 (in the U.S. and Canada) or your local Bose

office and request the “Balanced and Unbalanced Source Terminals” information packet (PN183072).

Input connections Instructions

Paging microphone 1. Connect the signal wires of the paging microphone to the quick connect

terminal block.

2. Insert the quick connect terminal block into the paging microphone input.

Telephone systems (PBX) and a Follow the connection diagram for a balanced or an unbalanced source found
central paging signal (such as in in the “Balanced and Unbalanced Source Terminals” information packet
malls) available from Bose. Call your local Bose office and request it.

Music source The following two audio sources are available:

• Music Input A accommodates either balanced or unbalanced configurations.
– For balanced sources, use the quick connect terminal block.
– For unbalanced sources, use the RCA (phono) connectors.

• Music Input B accepts unbalanced RCA plugs only.

Remote control The cable should consist of two wire pairs (22-24 gauge or heavier), with an

overall jacket. Select the wire according to safety agency requirements for the
installation. No hazardous voltage is present on these wires. One twisted pair
might be two white wires, the other pair two black wires.

®

The remote volume control wires carry small DC voltages (less than 15V) derived from high impedance circuits and
do not constitute a safety hazard. Two of the conductors are at the chassis ground potential of the amplifier.

• Use the black pair to connect the potentiometer to the Remote Volume connector on the amplifier

• Use the white pair to connect the switch to the Remote Select switch on the amplifier

The bare wires connecting the remote control to the amplifier are not a hazard. Shorting any or all of them will not
damage the system. However, if the wires are not properly terminated, there may be unwanted source selection or
muting of the system.

Note: For convenience during setup, connect the remote control temporarily using a short cable.

Output connections Instructions

Page The Page Output provides a line-level signal consisting of the paging announcements

only. This can be fed to power amplifiers and loudspeakers (or a powered loudspeaker)
for a zone such as a valet parking station. The Page Output is muted until a paging
signal triggers it. It puts out about 2V. The Remote Control unit DOES NOT control this
output.

Line Out L and R Complex, extended systems can be created originating with the FreeSpace® 6 system

electronics. The two Line Outputs provide a pair of signals useful for system expansion.
The signals available depend upon the setting of the Line Output Selector switch in
block 10.

• Top position: stereo music without paging

• Center position: stereo music with paging

• Lower position: only mono music at left; mono music + paging at right

Loudspeaker outputs Connect a dedicated loudspeaker cable from each of the four loudspeakers to each

amplifier terminal pair. Each output channel on the amplifier connects directly to one
loudspeaker. The red terminal (+) of the loudspeaker connects to the positive (+)
terminal on the amplifier. If one or more loudspeaker is not connected properly, a loss in
bass output can result.

3.0 System Setup

Use the electronic system card (found in the documentation kit) to mark the settings of the zones used in this installa­tion. See page 20. This card is to be stored inside the electronic system cover as an aid in troubleshooting problems.

3.1 Power on/off

The on/off switch is on the right side of the system electronics. If desired, the switch can stay in the ON position.
Power consumption without a signal input is typically less than 10 Watts.

3.2 Opti-voice® compressor

The Opti-voice compressor maintains a constant output level for inputs varying over a 30dB range. A LED in block 2
glows green when the compressor is active, but flashes red if the paging circuit is close to being overloaded. Use the
compressor when the microphone is used in one or more of the following ways:

• More than one person is using it

• Users vary in how loud they talk into it

• Users vary in how close they hold it to their mouth

Do not use the compressor in cases where:

• There is a tendency for feedback (howling sound, due to loudspeakers being picked up by the microphone)

• The source is a line level signal from a mixer or amplifier with similar signal processing

English

3.3 Music compressor

The music compressor solves the problem created as the audio industry improves the dynamic range of program
material. The music compressor takes about 25dB out of the 90dB or so dynamic range of modern digital program
material and is quiet and unobtrusive in operation. It boosts the quiet passages and leaves the loud passages alone.
It can even be used on highly compressed material, such as broadcast FM popular music, since it will not do much
additional compression on this already compressed material.

3.4 Setting levels

Make the gain adjustments after completing the connection of all source, loudspeakers, and auxiliary expansion
components. Refer to Figure 1 to locate the blocks referred to in this document.

3.4.1 Music sources

Before beginning adjustments, set the music controls as follows:

Control Name Block Set to...

1. Have someone continuously speak into the microphone while adjusting the controls. If the microphone has a
push-to-talk switch, hold it ON during the adjustments. A music source should also be playing. For optimum
results, follow these tips:

• Keep the microphone about 6 inches (15 cm) from the mouth

• Speak at a normal vocal level

3.4.2 Paging source (cont’d)

2. While speaking into the microphone, slowly turn down (to the left) the Page Trigger Level control (block 3) until
the amplifier disables paging and the LED in block 3 goes out.

Turn the control back to the right until the paging comes ON again.

3. Have the person stop speaking, but keep the push-to-talk button ON. The LED in block 3 should go out and the
music source should fade in.

4. Have the person resume speaking with the push-to-talk button ON. The paging source returns and the music
source fades out.

3.4.3 Page/music balance

Follow these steps to set the music and the paging levels.

1. Turn on Music Sources A and B.

2. Use the Remote Volume control to adjust the overall level.

3. Use the remote control to select Source A.

4. Have the person speak into the microphone. Adjust the Page Mix Trim (block 4) until the announcement is just

loud enough to be heard clearly. Be sure to set the paging level loud enough to be heard in noisy environments,
such as when a room is filled with loud patrons.

5. Have the person speak again, louder and closer to the microphone. If the Opti-voice® compressor is used, it
should reduce the gain, maintaining a reasonable level, and preventing audible distortion.

6. Switch to Music Input Source B. If Music Input Sources A and B levels are imbalanced, readjusting the settings
following the instructions in Section 3.4.1, “Music sources” may be necessary. If readjusting the Music Source
trims in block 6, watch the Music Compressor LED in block 7 to be sure it is not flashing red.

3.5 Monaural installations

If the music
source is... Then...

Monaural Use a “Y” connector cable to connect the source to both the L and R inputs. Then set this switch

to stereo (up).

Another option is to connect the source to the L input only. Then set the mono/stereo switch to
mono (down). The mono source will play at both L and R loudspeaker outputs. However, system
sensitivity will be reduced by 6dB. In this case, use a 400mV source level to reach full power. Most
sources will deliver 400mV at full modulation without a problem.

Mixed (1 mono Use a “Y” connector to feed the mono source into both the L and R inputs. The stereo source is
and 1 stereo) connected to the other source input. Set the mono/stereo switch to stereo.

3.0 System Setup

3.6 Dual zone, single source system

The FreeSpace® 6 business music system can be used to create a two-zone single source installation using the same

English

monaural music source. Each zone can have different loudness levels and a choice of page overrides. There is no
provision for independent page sources for the two zones—there is only one page input on the system electronics.

3.6.1 L zone trim (block 13)

This trim adjusts the level of the “left” zone relative to the “right” zone in mono installations, where one group of
loudspeakers on the left amplifier output must be adjusted in level relative to a second group of loudspeakers on the
right amplifier output. The control has a range of 0dB to –6dB. Use the R loudspeaker outputs to drive the zone that
is supposed to be the louder of the two, and use the L loudspeaker outputs for the quieter zone.

3.7 Page enable (block 5)

Page Enable switches can be used to determine which, if either, zone receives paging.

One special issue attaches to the use of the Page Enable switches in this two-zone case. The phase of the loud­speaker output is inverted when paging is enabled (180˚ phase reversal). If one zone has paging enabled and the
other zone has paging disabled, the loudspeakers in the L zone will be out of phase with the loudspeakers in the R
zone. Since the whole point of using the two zones is to provide a differentiated set of zone signals, there will usually
be enough separation between zones so that there is no overlap region where acoustic energy from both zones is
present. If, however, there is an overlap zone, sensitive listeners may sense “something funny” from the sound,
especially as they move around in the overlap region. There could also be a perception that the bass is diminished in
this region.

Avoid an overlap zone if using a FreeSpace business music system in this way.

3.8 Loudspeaker equalization switch and the bass and treble con-

trols (block 12)

The loudspeaker equalization switch is used to select the proper equalization for the loudspeaker type you have
installed. Selecting the incorrect equalization will produce undesireable results.

The bass and treble controls may be used to make a final “touch-up” of the frequency response in the installation.

These controls have a range of about ±6dB maximum, and will generally be left flat (turned to their center position).

Bose® engineers have carefully adjusted fixed and dynamic equalization in the system electronics amplifier to yield an
acoustically correct frequency response. However, some environments with many cloth wall hangings might benefit
from a slight treble boost.
