Thank you for purchasing TOA’s Speaker System.
Please carefully follow the instructions in this manual to ensure long, trouble-free use of your equipment.
1. SAFETY PRECAUTIONS
• 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.
Safety Symbol and Message Conventions
Safety symbols and messages described below are used in this manual to prevent bodily injury and property
damage which could result from mishandling. Before operating your product, read this manual first and
understand the safety symbols and messages so you are thoroughly aware of the potential safety hazards.
WARNING
CAUTION
Indicates a potentially hazardous situation which, if mishandled, could
result in death or serious personal injury.
Indicates a potentially hazardous situation which, if mishandled, could
result in moderate or minor personal injury, and/or property damage.
WARNING
When Installing the Unit
• Avoid installing or mounting the speaker in unstable
locations, such as on a rickety table or a slanted
surface. Doing so may result in the speaker falling
down and causing personal injury and/or property
damage.
• Refer all installation work to the dealer from whom
the speaker was purchased. 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.
·
• Install the speaker only in a location that can
structurally support the weight of the speaker and
the mounting bracket. Doing otherwise may result
in the speaker falling down and causing personal
injury and/or property damage.
2
• Owing to the speaker’s size and weight, be sure
that at least two persons are available to install the
speaker. Failure to do so could result in personal
injury.
• Do not use other methods than specified to mount
the bracket. Extreme force is applied to the speaker
and the speaker 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 stand in combination.
Doing otherwise may cause the speaker or
component to fall off, resulting in personal injury.
• Cautions when using the speaker stand
Be sure to carefully observe the following
instructions. Ignoring them could result in the
speaker system toppling over or falling down,
possibly resulting in personal injury.
· Open the stand legs to their full extension.
· Do not extend or fold the tripod while the speaker
is mounted.
· Install the stand on a flat, hard surface.
· Avoid placing the speaker in a doorway or other
high-traffic area where people may trip over the
equipment or cords.
· In outdoor installations, take such measures as
securing speakers with safety wire to prevent
them from being toppled over due to strong wind,
etc.
CAUTION
When Installing the Unit
• When unpacking or moving the speaker, be sure
to handle it with two or more persons. Falling or
dropping the speaker may cause personal injury
and/or property damage.
• Do not stand or sit on, nor hang down from the
speaker as this may cause it to fall down or drop,
resulting in personal injury and/or property damage.
• Have the speaker checked periodically by the shop
from where it was purchased. Failure to do so may
result in corrosion or damage to the speaker that
could cause the speaker to fall, possibly causing
personal injury.
When the Unit is in Use
• Do not operate the speaker for an extended
period of time with the sound distorting. This is an
indication of a malfunction, which in turn can cause
heat to generate and result in a fire.

2. GENERAL DESCRIPTION
Developed for the mobile sound reinforcement applications, TOA's SR-F1D and SR-L1B make up a speaker
and subwoofer system which features high power handling capability, high quality and durable construction.
3. FEATURES
• The SR-F1D can reproduce both low and high frequencies (bi-amp operation), while the SR-L1B clearly
reproduces super-low frequencies. Both systems are used in conjunction with a digital processor.
• The SR-F1D reproduces low frequencies with excellent transient response thanks to its high-efficiency
30 cm woofer with large 20 cm diameter magnet.
• The SR-F1D's driver employs a titanium diaphragm and features high sound quality and high power handling
capability. Its constant directivity horn (60° horizontal x 40° vertical) has a smoothed cross-sectional area and
provides a uniform sound field and smooth sound quality.
• The SR-L1B's 38 cm woofer consists of a strong magnetic circuit employing a large 20 cm diameter magnet
and a 72 mm diameter long voice coil. This combination permits ultra-linearity down to super-low frequencies
while realizing high power handling capability.
• The enclosure is constructed of high-strength Apitong plywood. Since the outside surface is covered in
polyurethane resin, the speaker also features high durability to stand up to rough handling when used on the
road.
• Neutrik NL4MPR input connectors ensure quick and accurate system field installations.
• The SR-F1D features flying hardware (ring/stud pan fittings) installed on its top and bottom. The bottom
surface is also equipped with built-in nuts for mounting on an optional stand.
• Because the sides of the SR-F1D's enclosure are angled at 15°, when multiple speakers are arranged sideby-side, they can be oriented in a radial array, which helps suppress mutual interference at high frequencies.
4. INSTALLING THE SR-F1D ON THE SR-L1B
• When one SR-F1D is installed
on the SR-L1B
• When two SR-F1Ds are
installed on the SR-L1B
Align with the front surface
of the SR-L1B.

5. FlyinG (SR-F1D only)
WARNING
• Be sure to refer flying construction work to the dealer from whom the speaker was purchased.
• Avoid flying methods other than those described in this section.
Otherwise, the suspension wires or belts may be off or snap and the speaker may fall off, causing personal
injury.
Shown below are the general flying methods:
SR-F1D's flying hardware
• Use the pan fitting rings attached to the speaker’s top and/or bottom.
• Provide at least two suspension points on each speaker’s top.
• The maximum number of speakers that can be suspended vertically
is three.
Do not suspend as illustrated below:
• Use of a single wire that
has formed a loop
• Flying through only one
suspension point on the
top.
• Flying through handles.
• Flying using the nuts on
the bottom surface
• Vertical suspension of 4 or
more speakers.

6. SPEAKER STAND FOR SR-F1D
The speaker stand manufactured by Köning & Meyer GmbH (K & M) of Germany is made available for use with
TOA's SR-F1D speaker.
The speaker stand consists of two main sections, which are sold separately.
Stand:
Model 213
Stand bracket: model 195/8
Step 1. Extend the stand's legs.
Loosen the tripod fixing screw and open the tripod
legs outward so that the stays become level.
Then, tighten the fixing screw.
SR-F1D
WARNING
Fully extend the stand’s tripod legs and place
the stand on a stable surface. If the tripod is not
sufficiently extended, the stand could topple over,
possibly resulting in personal injury.
Step 2. Attach the stand bracket to the speaker using the
speaker mounting screws and plain washers.
Step 3. Loosen the bracket fixing screw, then place the
speaker on the stand.
After setting the speaker's orientation, retighten the
bracket fixing screw.
WARNING
Owing to the speaker’s size and weight, be sure
that at least two persons are available to install the
speaker. Failure to do so could result in personal
injury.
Step 4. Adjust the stand height.
4-1. Loosen the height fixing screw.

then retighten the handle screw.
4-3. While holding down the lock button, adjust the
speaker's height by turning the height adjustment
handle. (Clockwise rotation raises the speaker.)
Note
You cannot rotate the handle unless the lock button
is continuously pressed. To complete the height
adjustment, ensure that the shaft is locked when
the lock button is released. (This can be checked by
rotating the handle slightly.)
Step 5. Retighten the height fixing screw.
Note
Leave the handle folded back except when adjusting the height.
