Suspending the SR-F1B

Note: The SR-L1B can not be suspended.

Caution

The SR-F1B weighs approximately 37 kg. Confirm that the structure of installation place, and suspending wires or belts
are heavy-duty enough to support the total weight of the load before suspension. Secure to lock the fixing metals of the
suspending wire or belt to the speaker. TOA takes no responsibility for any accidents or injuries resulting from the fall
of the SR-F1B due to incorrect installation.

• As for t he general suspending methods of t he SR-F1 B, refer to the figures below.

Be sure to use t w o suspending w ires or belts.

Fix them to the ceiling reinforcement

individually.
Even in case of oblique installation of the

speaker, be sure to use two suspending wires
or belts.

WARNING

Never suspend the speaker as shown in the figures below.

Never use a ringed one wire.

Never suspend the speaker
with a s ing le wire.

Never link more than three

speakers vertically.

Never suspend the speaker using

the speaker handles.

SR-F1B SPEAKER FLYING SYSTEM

This speaker flying hardware system is manufactured by ATM FLY-WARE™ (ATM GROUP, Inc.) of the United States for use
with TOA's SR-F1B speaker. The flying system enables various speaker array configurations to be constructed quickly and

safely without special components.

SYSTEM COMPOSITION

The flying system is comprised of five main components.

1 .[AMFS-SRF1-TH Truss Module] Allowable load 275 kg

The truss module attaches to both the top and bottom of the SR-F1B
speaker.

<Note> Speaker fixing screws are supplied with the truss module.

2 .[AMFS-1X2-30 Connecting Bar] Allowable load 278 kg

The connecting bar is used for horizontal speaker connection.

3 .[AMFS-1X2-SME Shackle Mount] Allowable load 225 kg

The shackle mount is used to set suspension points for vertical speaker
suspension.

(Multiple

rows

of

speakers

can be

suspended

at

different

tilt

angles.)

4.[AMFS-1X2-SB Stacking Bracket] Allowable load 194 kg
The stacking bracket is used to suspend multiple rows of speakers in a
straight vertical format without varying

array

tilt

angles.

5 . [2.5QRP Quick Release Pin] Allowable load 835 kg

The quick release pin has a lock function and is used to connect
individual parts.

MOUNTING TRUSS MODULE

Truss module

Pan fitting ring

Hexagon bolt 3/8" x 41/2"

Caution

Never use mounting
hardware other than
supplied.

WARNING

EXAMPLE OF USAGE

The following limitations must be observed even when the allowable load

requirement is met.

(1) A maximum of four speakers can be suspended per shackle mount

(AMFS-1X2-SME) or stacking bracket (AMFS-1X2-SB).

Example 1: A column of eight speakers configured two high and four wide

can be suspended from two AMFS-1X2-SME Shackle Mounts.

Example 2: A column of ten speakers configured two high and five wide

would require suspension from a minimum of three AMFS-1X2­SME Shackle Mounts.

(2) A maximum of three rows of speakers using this flying hardware system

may be suspended in the vertical plane.

Confirm the following points before installation.

(1) Total actual load of each component must be lower than the allowable

load for that component.

(2) All quick release pins (2.5QRP) must be inserted into other components

to lock them securely.

(3) All components that relate to array suspension (i.e. enclosures, individual

components of the flying hardware system, clamps, connectors, and
suspension devices) must be free from any deformation, crack and
corrosion.

SR-F1B SPEAKER STAND

This speaker st an d is m anufactured by König&Meyer Gm bH(K&M) of Germany for use with TOA's SR-F1B speaker.
The speaker stand consists of two main sections:

Stand: Model 213

Bracket: Model 19582

USAGE

(Refer

to

Fig.

1.)

Extending the Stand Legs.

1 . Loosen the tripod clamp screw and extend the tripod legs by

sliding the clamp ring down the length of the stand until the leg
stays are horizontal, then retighten the screw.

Mounting the Speaker.

2 . Attach the stand bracket to the base of the speaker using the

supplied mounting screws and washers. (Fig. 2).

3 . After ensuring that the bracket clamp screw is loose and not

protruding into the interior of the bracket, carefully place the

speaker on the stand by sliding the bracket over the end of the
stand.

4 . After positioning the speaker, tighten the bracket clamp screw.

Adjusting Stand Height.

5 . Loosen the height lock screw.
6 . Loosen the handle clamp screw, then fold out the crank handle

and retighten the screw.

7 . While holding d own the lock button, adjust the speaker's height by

turning the crank handle. (Clockwise rotation raises the speaker.)

The handle cannot be turned without holding down the lock button.
After adjustment is completed, release the lock button and make sure
that the shaft is securely locked. (This can be checked by rotating the

handle slightly.)

8 . Retighten the height lock screw .
9 . Loosen the handle clamp screw, flip the handle back into its

foldaway position and retighten the handle clamp screw. Be sure
the handle is always folded up except when adjusting the height.

Removal After Use

10. After use, lower and detach the speaker, then collapse the stand
in the reverse order of the above procedure.

Speaker Mounting Screw Storage

After the stand bracket is detached from the speaker, the speaker

mounting screws can be inserted into the threaded holes of the stand

bracket for storage. (Fig. 3).

PRECAUTIONS

Only use the stand on flat, hard ground or floor surfaces.

Avoid installing the stand near narrow passages where passers by might trip over the tripod legs.

When using the stand outdoors, take care to avoid exposure to strong winds.

To reduce the chance of the stand toppling over, avoid extending the stand too high.
When there is potential for instability and the danger of a fall, be sure to secure the stand with guy wires or other
devices.

unit and the mounting bracket. Doing otherwise may result in the unit falling
down and causing personal injury and/or property damage.

Caution

CAUTION

Indicates a potentially hazardous situation which, if mishandled, could
result in moderate or minor personal injury, and/or property damage.

Install th e unit only in stable locations, and make appropriate arrangements to

prevent it from falling down or rolling cross the floor. If it falls down or moves,

this may cause personal injury and/or property damage.

Caution

When unpacking o r moving a heavy unit, be sure to handle the unit with two or

more persons. Falling or dropping the unit may cause personal injury and/or
