Before installation or use of the TOA HS-120W, be sure to carefully read all the instructions in the manual for correct and safe operation.

Be sure to follow all the precautionary instructions, which contain important warnings and/or cautions regarding safety.

After reading, keep the manual handy for future reference.

WARNING: Indicates a potentially hazardous situation which, if mishandled, could result in death or serious personal injury.

• Avoid installing or mounting the unit in unstable locations, such as on a rickety table or a slanted surface. Doing so may result in the unit falling down and causing personal injury and/or property damage.

• Install the unit only in a location that can structurally support the weight of the unit and the mounting bracket. 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. Also, when it gets wet with rain, there is a danger of electric shock.

• Owing to the unit’s size and weight, be sure that at least two persons are available to install the unit. 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 unit and the unit could fall off, possibly resulting in personal injuries.

• Use screws that are appropriate for the ceiling’s or wall’s structure and composition. Failure to do so may cause the unit to fall, resulting in personal injury.

• Ensure that all screws are securely tightened. If they are not tightened or firmly secured after installation, the unit could fall down, possibly resulting in personal injury.

• Use the specified mounting bracket in combination. Doing otherwise may cause the unit or component to fall off, resulting in personal injury.

• Do not mount the unit in locations exposed to constant vibration. The mounting bracket can be damaged by excessive vibration, potentially causing the unit to fall, which could result in personal injury.

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

• When unpacking or installing the unit, be sure to handle it with two or more persons. Falling or dropping the unit may cause personal injury.

• Avoid touching the unit’s sharp metal edge to prevent injury.

• To avoid electric shocks, be sure to switch off the amplifier’s power when connecting speakers.

• Do not place heavy objects on the unit as this may cause it to fall or break which may result in personal injury and/or property damage. In addition, the object itself may fall off and cause injury and/or damage.

• Make sure that the volume control is set to minimum position before power is switched on. Loud noise produced at high volume when power is switched on can impair hearing.

• Do not operate the unit 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.

• Tweeter array realizes a 90° horizontal x 40° vertical directivity control at high frequencies

• Compact and lightweight with its high frequency tweeter array arranged in front of the low frequency woofer

• Built-in overload protection circuitry for the tweeters

• Both permanent and temporary installations available

• Either vertical or horizontal speaker installation available for the permanent installation

• Easy to carry with a handy handle

The dimensions for the TOA HS-120W are as follows:

Unit: mm (inches)

The TOA HS-120W has two types of input terminals: a Speakon connector and a screw terminal. These are internally connected in parallel, so you can use either one.

• Screw Terminal: Connect the positive (+) and negative (-) speaker wires to the corresponding terminals.

• Speakon Connector: Use a NEUTRIK NL4FX Speakon connector on the cable end to connect to the speaker’s NEUTRIK NL4MP input.

The connection diagram is as follows:

• Speaker ⊕ is connected to 1+ on the Speakon connector and the positive screw terminal.

• Speaker ⊖ is connected to 1- on the Speakon connector and the negative screw terminal.

Terminals 2+ and 2- on the Speakon connector are not used.

The TOA HS-120W has a built-in input overload protection circuit. If an excessive input signal is applied to the speaker, this circuitry activates and cuts off the signal input to the tweeters. A sudden drop in the sound volume level during operation indicates that the protection circuitry has been activated.

If this happens, reduce the amplifier volume and wait. The protection circuitry will automatically reset after approximately 10 seconds. After the circuitry resets, set the volume at a lower level than before.

Note: This protection circuit does not completely protect the speaker components. Depending on the nature of the excessive input, damage may occur before the circuit can operate. Also, if an excessive input signal is applied for extended periods, the protection circuitry may be damaged and not recover. Take special care to avoid applying excessive input signals to the speaker.

To mount the TOA HS-120W speaker vertically, you must use the optional HY-1200VB (black) or HY-1200VW (white) Mounting Brackets. These brackets are designed to mount the speaker to ceilings or walls vertically.

They allow the speaker’s vertical angle to be adjusted:

• Ceiling Mount: Adjustable from 15° upward to 90° downward.

• Wall Mount: Adjustable from 15° upward to 60° downward.

Note: For horizontal angle adjustment, these brackets can be used in conjunction with the optional HY-C0801/HY-C0801W Ceiling Mount Bracket or the HY-W0801/HY-W0801W Wall Mount Bracket.

To mount the TOA HS-120W speaker horizontally, use the optional HY-1200HB (black) or HY-1200HW (white) Mounting Brackets. These brackets are designed for horizontal mounting to ceilings or walls.

They allow the speaker’s vertical angle to be adjusted:

• Ceiling Mount: Adjustable from 0° horizontal to 90° downward.

• Wall Mount: Adjustable from 15° upward to 60° downward.

Note: For horizontal angle adjustment, these brackets can be used in conjunction with the optional HY-C0801/HY-C0801W Ceiling Mount Bracket or the HY-W0801/HY-W0801W Wall Mount Bracket.

To enable horizontal angle adjustment for a ceiling-mounted TOA HS-120W, you must use the optional HY-C0801 or HY-C0801W Ceiling Mount Bracket. This bracket is used in conjunction with the main HY-1200 series Mounting Bracket (either vertical or horizontal model).

To enable horizontal angle adjustment for a wall-mounted TOA HS-120W, you must use the optional HY-W0801 or HY-W0801W Wall Mount Bracket. This bracket is used in conjunction with the main HY-1200 series Mounting Bracket (either vertical or horizontal model).

When mounting the TOA HS-120W to a ceiling or wall, install a safety wire as needed. Failure to follow these instructions may cause the speaker to fall, resulting in personal injury.

• Use a wire rope of 2 mm (0.08″) or more in diameter. (The safety wire is not supplied.)

• Tighten the safety wire to take up the slack. Otherwise, impact shock at speaker fall may cause the wire-connected parts or wire itself to break.

• Install the safety wire to a place that can structurally support the full weight of the load.

• Screw a speaker suspension bolt (M8) into one of the screw holes on the speaker’s bottom surface. The M8 bolt should have a screw pitch of 1.25 mm and an effective depth of 24 mm. (Note: Unified inch screws cannot be used). Then, connect the safety wire to the bolt.

To change the orientation of the front panel logo, for example when mounting the speaker horizontally, simply turn the logo mark while holding its edges.

Follow these steps to mount the speaker on the optional ST-33B stand. Refer to the instruction manual enclosed with the Speaker Stand for more details.

Step 1. Fix the bracket supplied with the speaker stand to the speaker using the supplied M8 speaker mounting screw and plain washer.

Step 2. Spread the tripod legs of the stand to their full extension. Note: Spread the tripod legs until the stays extend horizontally.

Step 3. Mount the speaker with the bracket fixed onto the stand.

Step 4. Determine the speaker direction, and tighten the bracket fixing screw.

Step 5. Adjust the stand height.

• When installing the speaker system on a slippery floor, put a non-slip mat under the speaker.

• Do not kick or stand on the speaker system, as this will damage the speaker.

Attach the supplied rubber feet for speaker storage or on-floor speaker installation. Use the supplied M6 x 30 screws to attach them.

Note: The rubber foot has a direction (back and forth). Align the datum line on the rubber foot with the positioning mark (a triangle) on the speaker unit when attaching.

The TOA HS-120W comes with a handy carrying handle. To attach it, use the supplied handle, handle fitting brackets, and M6 x 30 screws to fix the assembly to the speaker’s top surface.
