WARNING

Indicates a potentially hazardous situation which, if mishandled, could

result in moderate or minor personal injury, and/or property damage.

CAUTION

•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.

•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-304U 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-304U also employs a constant directivity horn for clear

sound output over the limited horizontal range of dispersion.

5. IMPEDANCE CHANGE

Input impedance is factory-preset to 330 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.
