INSTRUCTION MANUAL

1. SAFETY PRECAUTIONS

• Be sure to read the instructions in this section carefully before use.

• Make sure to observe the instructions in this manual as the conventions of safety symbols and messages

regarded as very important precautions are included.

• We also recommend you keep this instruction manual handy for future reference.

Safety Symbol and Message Conventions

Safety symbols and messages described below are used in this manual to prevent bodily injury and property

damage which could result from mishandling. Before operating your product, read this manual first and

understand the safety symbols and messages so you are thoroughly aware of the potential safety hazards.

Indicates a potentially hazardous situation which, if mishandled, could

result in death or serious personal injury.

WARNING

Indicates a potentially hazardous situation which, if mishandled, could

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

CAUTION

• Install the unit 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 install the speaker in kitchens or such locations where grease or oily smoke is generated. Failure to

follow this instruction could deteriorate the speaker mounting parts, causing the speaker to fall, which could

result in personal injury.

• Do not install the speaker in indoor swimming pools or such locations where liquid chemicals are used. The

parts deteriorate if corroded, causing the speaker to fall, which could result in personal injury.

• Avoid installing the speaker in locations exposed to sea breeze or corrosive gas. The speaker or its parts

may be subject to corrosion, that might cause it to fall or result in personal injury.

• 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. INSTALLATION PRECAUTIONS

• Be sure to position the speaker with its opening facing downward. Doing otherwise may cause rainwater to

accumulate inside the opening and lead to unit malfunction.

• Keep the speaker unit (in the back of opening) away from direct sunlight. Otherwise, ultraviolet rays

deteriorate the paper cone, causing the speaker to malfunction.

• Do not install the speaker in such constant high-temperature and high-humidity locations as bathrooms and

wet saunas. Waterproof performance may deteriorate, resulting in speaker malfunction.

3. GENERAL DESCRIPTION AND FEATURES

TOA's CS-64, CS-154, and CS-304 outdoor speakers feature waterproof plastic enclosures and stainless

steel hardware for all-weather durability. They are designed to offer the high-efficiency of weather-resistant

horns combined with the high sound quality of conventional cone speakers to provide clear, highly directional

sound reproduction. The CS-154 and CS-304 in particular feature constant directivity horns for clear sound

output over their narrow horizontal range of operation.

4. IMPEDANCE CHANGE

Input impedance is factory-preset as follows:

CS-64: 1.7 kΩ

CS-154: 670 Ω

CS-304: 330 Ω

To change the impedance, change the rear panel-mounted rotary

switch position using a standard screwdriver.

Note: (1) These speakers are designed to be used in conjunction with

the 70/100 V line amplifier. They cannot be connected to the

amplifier's low impedance terminals. (2) No sound is output

when the switch is set to the OFF position.

Caution: Never set the switch to "

–

" position for 100V line

operation, as doing so may result in damage to the speaker.

5. SPECIFICATIONS

* Impedance in brackets is for 70 V line.

Note: The design and specifications are subject to change without notice for improvement.
