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.
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-120 series and HS-150 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

• 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

6. 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.
7. INSTALLATION
7.1. 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.
7.1.1. 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-120 series speaker system
HY-1500VB and HY-1500VW: For the HS-150 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.

7.1.2. HY-1200HB, HY-1200HW, HY-1500HB and HY-1500HW Mounting Brackets
(For horizontal speaker mounting)
• These brackets are designed to mount HS series speakers to ceilings or walls horizontally.
HY-1200HB and HY-1200HW: For the HS-120 series speaker system
HY-1500HB and HY-1500HW: For the HS-150 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
HY-C0801W Ceiling Mount Bracket, or the HY-W0801 or HY-W0801W Wall Mount Bracket.

7.1.5. 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.

8. 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.
