INSTRUCTION MANUAL
WIDE RANGE SPEAKER
CS-154U
Thank you for purchasing TOA's Wide Range Speaker.
Please carefully follow the instructions in this manual in order to ensure long, trouble-free use of your equipment.
1. SAFETY PRECAUTIONS
• Before installation or use, be sure to carefully read all the instructions in this section for correct and safe
operation.
• Be sure to follow all the precautionary instructions in this section, which contain important warnings and/or
cautions regarding safety.
• After reading, keep this manual handy for future reference.
WARNING
Indicates a potentially hazardous situation which, if mishandled, could
result in death or serious personal injury.
• Install the speaker only in a location that can structurally support the weight of the speaker and the mounting
bracket. Doing otherwise may result in the speaker falling down and causing personal injury and/or property
damage.
• Do not stand or sit on, nor hang down from the speaker as this may cause it to drop, resulting in personal
injury and/or property damage.
CAUTION
Indicates a potentially hazardous situation which, if mishandled, could
result in moderate or minor personal injury, and/or property damage.
• Do not operate the speaker 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 AND FEATURES
TOA's CS-154U outdoor speaker features a resin enclosure and stainless steel hardware for all-weather
durability. It is designed to offer the weather resistance and high efficiency of horn speakers combined with
the high sound quality of cone speakers. The CS-154U also employs a constant directivity horn for clear
sound output over the limited horizontal range of dispersion.

Note
The rotary switch is factory-preset to 670 Ω.
5. IMPEDANCE CHANGE
The input impedance is factory-preset to 670 Ω.
To change the impedance, change the rear
panel-mounted rotary switch position to the
desired impedance (wattage) using a standard
screwdriver.
Notes
• This speaker is designed to operate on a 70 V
or 100 V line. Do not connect it to the
amplifier's low impedance line.
• No sound is output 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.
