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.

Indicates a potentially hazardous situation which, if mishandled, could

result in death or serious personal injury.

WARNING

Indicates a potentially hazardous situation which, if mishandled, could

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

CAUTION

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.

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.

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 high- and low-impedance applications available by a rotary switch

CAUTION

5. INPUT TERMINAL SECTION

• 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.

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.

6. IMPEDANCE CHANGE

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 Ωwhen using a low-

impedance amplifier.

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 wire-

connected 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.

WARNING

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.

9. EQUALIZING BY THE DIGITAL SIGNAL PROCESSOR

The speaker system is capable of providing high-efficiency and wide range reproduction without using an

equalizer, however more clear and dynamic sound quality can be reproduced by using our digital signal

processor and performing its settings as shown in the tables below.
