Thank you for purchasing TOA’s Speaker Systems.
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 instruction in this section for correct
and safe operation.
• Be sure to follow all the precautions in this
section, which contain important warnings and/or
cautions regarding safety.
• After reading, keep manual handy for future
reference.
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 fully out-door use
and have IP66 for IP rating. Please keep the unit
down face to keep the weather resistant capability
continuous.
• Owing to the unit’s size and weight, be sure that at
least two person 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
injury.
• Use screw that are appropriate for the ceiling’s or
wall’s structure and composition. Failure to do so
may cause the unit 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
damage 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 moderate or minor
personal injury, and/or property damage.
When Installing the Unit
• When installing the unit, be sure to handle it with
two or more persons. Falling or dropping unit may
cause personal 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 cause heat to
generate and result in a fire.

2. GENERAL DESCRIPTION
TOA’s CS-760-AS series is a compact two way speakers system design for high efficiency, high power
input handling capability, and high intelligible speakers suited for public address announcement and BGM
application in a fully outdoor environment. External loudspeaker components finished to ensure the unit’s
weatherproof capability. The CS-760-AS series employs rotary switch that facilities impedance change.
They can be installed in many different applications with combined use of the supplied mounting bracket
and the optional mounting brackets.
3. FEATURES
• Both permanent and temporary installations available.
• Impedance change applications available by a rotary switch.
• IP66 rating for protection from water and dust at fully outdoor installation.
• Built-in overload protection circuitry.

5. IMPEDANCE CHANGE
To change the impedance, use a standard screwdriver to rotate the rotary switch on the speaker’s rear side
to select the desired input power. This rotary switch is factory-preset to 170 Ω.

6. ABOUT THE INPUT OVERLOAD PROTECTION CIRCUIT
The speaker system features internal input overload protection circuitry for both high and low frequencies.
If an excessive input level is fed to the unit, the protection circuitry automatically cuts off the signal to the
speaker driver. A drastic reduction in sound volume for the high or low frequency range indicates that the
protection circuitry has been enabled. In such cases, simply reduce the amplifier volume. The protection
circuitry will automatically reset in approximately 10 seconds. After reset, maintain the volume at a level
slightly lower than before.
Note
This protection circuitry does not completely protect the unit against input overload. Depending on the type
or duration of excessive power input, the protection circuitry might not be enabled, resulting in damage to
the speaker driver. Also, if the excessive power input continues for a long period of time, the circuitry may
not be capable of resetting to its original condition. Take care so that the speakers are not exposed to
excessive power input.
7. INSTALLATION
2 3
The speaker system can be installed to ceiling, wall, and base floor using supplied bracket. The speaker
system installation is shown below.
This bracket is designed to mount the speaker system to ceilings, walls, and base floor vertically.
The bracket allow speaker’s vertical angle to be adjusted.
• Ceiling : From 0˚ to 90˚ downward
• Wall : From 8˚ upward to 106˚ downward
• Base floor : From 8˚ upward to 16˚ downward
Note:
Do not install the speaker system which is facing vertically upwards in a completely outdoor environment.
