Line Array Speaker SR-H2L, SR-H2S, SR-H3L, or SR-H3S.
Only 1 speaker can be suspended using the SR-FB3.
1. SPECIFICATIONS
Note: The design and specifications are subject to change without
notice for improvement.
Step 1. Attach the Suspension bracket to the speaker's rear
upper section.
Remove the specified screws on the speaker's rear
surface, then use their screw holes to secure the
Suspension bracket.
In this event, insert the Spacer between the speaker and
the Suspension bracket.
Note
For the bracket mounting position, refer to "Mounting
positions of the Suspension bracket and Pull-back bracket"
shown at right.
Step 2. Attach the Pull-back bracket to the speaker rear
surface.
Attach the Pull-back bracket in one of the following cases,
and install wires.
• When the speaker is to be suspended in fixed
installations
• If more downward angle is required when suspending the
speaker
Remove the specified screws on the speaker's rear
surface, then use their screw holes to secure the Pull-back
bracket.
Note
For the bracket mounting position, refer to "Mounting
positions of the Suspension bracket and Pull-back bracket"
shown below.
Step 3. Connect the suspension wires to both the suspension
holes in the Suspension bracket and Pull-back bracket.
Tips
Speaker's downward angle can be adjusted by selecting
the suspension holes in the Suspension bracket.
If more downward angle is required, connect the wire to the
Pull-back bracket, then pull it up and back.
Note
For details, read "Ceiling Suspension."
Step 4. Connect the speaker cable to the removable terminal

1. SAFETY PRECAUTIONS
2. INSTALLATION
3. CEILING SUSPENSION
• Before installation or use, be sure to carefully read all the
instructions in this section for correct and safe operation.
• Be sure to follow all the precautionary instructions in this section,
which contain important warnings and/or cautions regarding
safety.
• After reading, keep this manual handy for future reference.
• Refer all installation work to the qualified professionals.
Installation for flying requires extensive technical knowledge and
experience. The speaker may fall off if incorrectly installed,
resulting in possible personal injury.
• Flying Precautions
Be sure to follow the instructions below. Otherwise, the
suspension wires or belts may be off or snap and the speaker
may fall off, causing personal injury.
· Check to confirm that the suspension wires and belts are strong
enough to withstand the speaker load.
· The connectors of the suspension wires and belts must be
securely linked with those of the speaker.
· All parts and components (such as enclosures, metal pieces,
and screws) must be free from any deformation, crack, and
corrosion.
· Be sure to use screws supplied with the optional flying hardware
when installing the speaker using such hardware.
• Install the unit only in a location that can structurally support the
weight of the unit and the speaker. Doing otherwise may result in
the unit falling down and causing personal injury and/or property
damage.
• Since the unit is designed for in-door use, do not install it
outdoors. If installed outdoors, the aging of parts causes the unit
to fall off, resulting in personal injury.
• Do not use other methods than specified to mount the bracket.
Extreme force is applied to the unit and the unit could fall off,
possibly resulting in personal injuries.
• Tighten each nut and bolt securely. Ensure that the bracket has
no loose joints after installation to prevent accidents that could
result in personal injury.
• Use the specified speaker in combination. Doing otherwise may
cause the unit or component to fall off, resulting in personal injury.
• Avoid touching the unit's sharp metal edge to prevent injury.
• Do not put your weight on, nor hang down from the unit as this
may cause it to fall down or drop, resulting in personal injury
and/or property damage.
• Have the unit checked periodically by the shop from where it was
purchased. Failure to do so may result in corrosion or damage to
the unit or speaker that could cause the unit to fall, possibly
causing personal injury.
WARNING
Indicates a potentially hazardous situation which, if
mishandled, could result in death or serious personal injury.
CAUTION
Indicates a potentially hazardous situation which, if
mishandled, could result in moderate or minor personal injury,
and/or property damage.

Notes
• Only 1 speaker can be suspended using the SR-FB3.
(Never use the SR-FB3 to suspend the linked speakers.)
• Adjust the wire length so that uniform load is applied to each wire.
• When suspending the speaker, the angle of the suspension wires
must be within 10° from the vertical axis.
• When pulling the speaker up and back for adjusting the downward
angle, the inclination angle of the speaker’s rear surface must be
within 30° from the vertical axis.
