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

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.

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.  
Rotary switch  
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 low-  
impedance 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)  
• These brackets are designed to mount HS series speakers to ceilings or walls vertically.  
HY-1200VB and HY-1200VW: For the HS-1200 series speaker system  
HY-1500VB and HY-1500VW: For the HS-1500 series speaker system  
• They allow speaker’s vertical angle to be adjusted. (Ceiling: From 15° upward to 90° downward, Wall: From  
15° upward to 60° downward)  
Note: They also permit speaker’s horizontal angle to be adjusted in conjunction with the optional HY-C0801 or  
HY-C0801W Ceiling Mount Bracket, or the HY-W0801 or HY-W0801W Wall Mount Bracket.

• These brackets are designed to mount HS series speakers to ceilings or walls horizontally.  
HY-1200HB and HY-1200HW: For the HS-1200 series speaker system  
HY-1500HB and HY-1500HW: For the HS-1500 series speaker system  
• They allow speaker’s vertical angle to be adjusted. (Ceiling: From 0° horizontal to 90° downward, Wall: From  
15° upward to 60° downward)  
Note: They also permit speaker’s horizontal angle to be adjusted in conjunction with the optional HY-C0801 or

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.  
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.  
WARNING  
• 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.

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.
