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

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.
