When Installing the Unit
• Avoid touching the speaker'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 operate the speaker for an extended period
of time with the sound distorting. Doing so may
cause the speaker to heat, resulting in a fire.
• Do not stand or sit on, nor hang down from the
speaker as this may cause it to fall down or drop,
resulting in personal injury and/or property
damage.
• Have the speaker checked periodically by the shop
from where it was purchased. Failure to do so may
result in corrosion or damage to the speaker or the
mounts that could cause it to fall, possibly causing
personal injury.
Indicates a potentially hazardous situation which, if mishandled, could
result in moderate or minor personal injury, and/or property damage. CAUTION
2. GENERAL DESCRIPTION AND FEATURES
TOA's CS-64BS Wide range speaker features an ABS resin enclosure and stainless steel bracket for all-
weather durability. It is comprised of a high-efficiency weather-resistant horn and a high quality sound cone
speaker, providing clear and highly directional sound reproduction.
The CS-64BS is certified to the European Standard EN 54-24: 2008 and the International Standard ISO 7240-
24: 2010, and is compliant with the British Standard BS 5839-8: 2008.
• Wide range speaker suitable for voice evacuation, background music and paging announcements
applications.
• Comprised of a horn and cone speaker in combination, reproducing high efficiency and high quality sound.
• Weatherproof polyurethane resin paint protects the speaker from damage by ultraviolet light.
• Stainless steel bracket is protected from corrosion.
• Certified to EN 54-24, and ISO 7240-24, and is compliant with BS 5839-8.
• Equipped with a large steatite terminal block of screw type and thermal fuse.
• Provided with a cable gland on the terminal cover.
• One cable gland can be added, enabling bridge wiring.
• Impedance change available by a rotary switch located inside the terminal cover.
3. IMPEDANCE CHANGE
Input impedance is factory-preset to 1.7 kΩ.
To change the impedance, change the rear panel-mounted rotary switch position using a standard
screwdriver.
Notes
• This speaker is designed to be used for high impedance applications (70 V/100 V). Never connect the
speaker to low impedance line.
• No sound is output from the speaker when the switch is set to the OFF position.
Caution
Never set the switch to "–" position for 100 V line operation, as doing so may result in damage to the speaker.
