English 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. 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.
1.0 System Placement English ≥2 inch (50.8 mm) all sides ≤1 inch (25.4 mm) ≥2 inch (50.8 mm) all sides ≤1 inch (25.4 mm) 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.
English 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: • 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.
1.0 System Placement English 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 corresponds to a multiplier of 3.0. Multipliers for FreeSpace® 6 loudspeaker spacings are shown up to ±6dB direct field coverage.
English 1.0 System Placement The following chart and illustrations are examples of room sizes and shapes where the FreeSpace® 6 business music system works effectively. If your room is this long… (feet/meters) And this wide… (feet/meters) And this high… (feet/meters) And has this volume… (feet3 /meters3 ) Will FreeSpace 6 be effective? 30/9 30/9 9/2.
1.0 System Placement English 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. If your floor plan scale dimension is... Then your spacing circle diameter size is... 1 19⁄16 inch (4 cm) 1 31⁄8 inch (8 cm) 1 61⁄4 inch (16 cm) ⁄16 inch (.16 cm) ⁄8 inch (.31 cm) ⁄4 inch (.
English 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 doubt about these choices, consult a building trade professional, architect, or licensed professional engineer.
2.0 Installation English 2.1 Ceiling pans 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.

2.0 Installation English 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.
English 2.0 Installation 2.3 Electrical connections 2.3.1 Wire protection Note: If local code requires flexible metallic tubing or flexible metallic conduit, be sure it is well supported. Too much unsupported flexible metallic tubing or flexible metallic conduit can weigh the loudspeaker down, pushing it away from the ceiling surface. 2.3.2 Wire preparation Strip the wires to 5/16 inch (8 mm). Note: Stranded wire is recommended. DO NOT solder (tin) the wires. 2.3.
2.0 Installation The rotation feature provides access to the loudspeaker terminals during and after installation. Use this feature for extra support while completing electrical connections. The rotation feature is not an option if the ceiling is thick or the tiles are soft. 1 2 3 4 English ;;;;; ;;;;; ;;;;; ;;;;; ;;;;; 2.3.4 Rotation feature ;;;;;;; ;;;;;; ;;;;;;;;;;;;; 5 6 CLICK CLICK ;;;;;; AM180090_02_V.

Wear safety glasses. Keep hands and fingers clear of the ceiling pan while moving the spring. 1. Return the springs to their locked position. If possible, pull the loudspeaker down and rehook the springs in their locked position. 2. Lift the loudspeaker off the springs and remove it.
2.0 Installation English 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.

Be sure to observe all other safety precautions while drilling or installing the mounting hardware.
English 2.0 Installation 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. 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.
2.0 Installation 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.

Music Input Source A has a fixed level output Use it. If not, set the variable level output to maximum. Music compressor is ON for Music Input Source A Adjust the Music Input Source A Trim so the music compressor LED glows green during the loudest passages. If the LED changes to red, the level is too high.
3.0 System Setup English 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.
English 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 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.
Troubleshooting English Symptom Possible Cause Remedy System electronics power LED does not light The power switch is off Turn on power switch. The power cord is loose, not installed, or defective Correct the power cord problem. The circuit breaker handling this AC outlet has tripped Turn off the power switch and reset the circuit breaker. If the breaker trips again, there is a problem in the building wiring, or other loads plugged into the same circuit. Call an electrician.
English Troubleshooting Symptom Possible Cause Remedy The loudspeakers go silent after a half hour or so of operation The amplifiers are shutting down from thermal overload Check that the installation permits adequate air flow around the system electronics and correct if it does not. Feed back during paging from a microphone There is too much gain for the paging signal Reduce the gain with the Page Source Gain Trim or the Page Source Gain Switch (block 1).
