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

Indicates a potentially hazardous situation which, if mishandled, could

result in death or serious personal injury.

When Installing the Unit

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 Installing the Unit

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.

CAUTION

Indicates a potentially hazardous situation which, if mishandled, could

result in moderate or minor personal injury, and/or property damage.

When the Unit is in Use

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.

2. GENERAL DESCRIPTION

TOA’s HS-1200 series and HS-1500 series speakers are 2-way speaker systems made of resin, and feature a large diameter woofer. They can be installed in many different applications with combined use of the supplied handles and the optional mounting brackets.

3. FEATURES

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

Both highand low-impedance applications available by a rotary switch

As the Speakon connector is internally connected in parallel to the screw terminal as shown below, you can use either of the two.

The usable connector (on the cable end) that matches the NEUTRIK NL4MP Speakon is NEUTRIK NL4FX Speakon.

Input terminal connection diagram is as shown below.

6. IMPEDANCE CHANGE

[Rear]

To change the impedance, use a standard screwdriver to rotate the rotary switch on the speaker's rear panel to select the desired input power.

This switch is factory-preset to 670 Ω.

Note

When using a high-impedance amplifier, never select 8 Ω, as this will damage the speaker and the amplifier.

Be sure to turn the rotary switch to 8 Ω when using a lowimpedance amplifier.

The figure represents factory-preset position.

7. ABOUT THE INPUT OVERLOAD PROTECTION CIRCUIT

The speaker system has a built-in input overload protection circuitry. If an excessive input signal is applied to the speaker, the protection circuitry is activated and cuts off the signal input to the tweeters. A sudden drop of the sound volume level during speaker operation indicates that the protection circuitry has been activated. In such a case, reduce the amplifier volume and wait. The protection circuitry is automatically reset after approximately 10 seconds. After the circuitry is reset, set the volume at a lower level than before.

Note

This input overload protection circuitry does not completely protect the speaker component. Depending on the nature of the excessive input signal applied to the speaker, there may be damage to the speaker components before protection circuitry can operate. Also, if the excessive input signal is applied to the speaker for extended periods of time, the protection circuitry may be damaged and will not recover. Take special care that the excessive input signal is not applied to the speaker during use.

8. INSTALLATION

8.1. Installing to a Ceiling or Wall

Install the speaker system to a ceiling or wall using the optional mounting brackets shown below.

Note

Refer to the instruction manual enclosed with the HY-1200 series or HY-1500 series Mounting Bracket for its mounting details.

8.1.1.HY-1200VB, HY-1200VW, HY-1500VB and HY-1500VW Mounting Brackets (For vertical speaker mounting)

8.1.5. Safety wire installation (For speaker fall prevention)

When mounting the speaker system to the ceiling or wall, install a safety wire as needed.

WARNING

When installing the safety wire, be sure to follow the instructions below.

Failure to do so may cause the speaker to fall off, 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 wireconnected parts or wire itself to break.

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

Screw a speaker suspension bolt (M8) into one of the screw holes on the speaker's bottom surface. Then, connect the safety wire to the bolt.

8.2. Mounting on the ST-33B Speaker Stand (optional)

Speaker's bottom surface

Note

Refer to the instruction manual enclosed with the Speaker Stand for its mounting details.

Step 1. Fix the bracket supplied with the speaker stand to the speaker.

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.

8.3. Using as a Floor Monitor

Notes

• When installing the speaker system on 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.

The figure shows the HS-1200 series.

8.4. Attaching the Supplied Rubber Feet

Attach the rubber feet in the case of speaker storage or on-floor speaker installation.

Note

The rubber foot has a direction (back and forth).

Align the datum line on the rubber foot with the positioning mark ( ) on the speaker unit as shown at right.
