Environment
Never place this product in an environment which could alter its performance or reduce its service life. Such environments usually include high levels of heat, dust, moisture, and vibration.
Important Safety Instructions
1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
4. Follow all instructions.
5. Do not use this apparatus near water.
6. Clean only with dry cloth.
7. Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.
8. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat.
9. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide blade or the third prong are provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.
10. Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from the apparatus.

Setup and Operation
Setup and Operation
After unpacking your CH-522/532 Clear Horn Speakers, attach the speakers to a wall or other secure surface using the integrated mounting bracket, as shown in the illustration below.
Mounting Bracket
WARNING: under no circumstances should any loudspeaker be mounted or suspended in a public place unless
the mounting method has been approved and certified by a qualified engineer. Failure to properly secure the system can result in damage to the unit or personal injury.

Connecting your Speaker System
Connecting your Speaker System
Always switch off the power to the amplifier before connecting speakers.
Choosing the Correct Speaker Cable
It is important to choose cabling designated for audio use and good quality connectors. Using guitar cable or zip cord (designed for lamps and other electrical use) or poor quality connectors will degrade your loudspeakers’ audio performance. For distributed loudspeaker systems, we recommend stranded twisted pair speaker cable with an overall vinyl jacket (plenum rated when installed in required installations).
Always use the appropriate gauge of speaker cable. For cable runs of less than 25 feet (7.5 meters), 18- gauge cable is adequate. For longer cables, we suggest 16-gauge stranded cable.
Speaker Connection Procedures
After removing approximately 10mm (1/4-inch) of insulation from the ends of the speaker cables, twist the strands tightly and then twist together with the distribution cable(s), using an appropriate cable connector.
Make certain the wires do not protrude from the cable connector and touch any metal on the speaker chassis, or any other adjacent metal.
Maintaining Proper Polarity
It is very important to wire your speakers consistently in order to maintain proper polarity. All quality cables are manufactured with clear markings to identify the different conductors – normally by color-coding, printed markings, or textured ribbing on the cable’s jacket material. Failing to do so will cause your speakers to operate out of phase, resulting in significantly reduced low-frequency output from your system.
Choosing the Correct Amplification
When selecting an amplifier for use with your distributed speaker system, it is important to choose an amplifier that has sufficient power output.
Choosing an amplifier that does not have adequate rated power may result in pushing the amp beyond its limits, producing distortion or “clipping” of the signal. This can irritate the listener and may cause damage to the speaker.
Choosing an amplifier that is over-powered can result in over-driving the speaker system.
Using Multiple Loudspeakers
It is important to consider the overall speaker load (impedance) when connecting distributed speaker systems to an amplifier. Some distributed loudspeakers are marked in load impedance; others show the wattage taps. Whatever the case, it is easy to compute the total impedance (or wattage load) that is possible for a given amplifier.
