Introduction

WARNING

! This loudspeaker must be installed by a qualified technician as it involves such tasks as selecting a location for installation, drilling holes in walls/ceiling and wiring.

Have the installer carefully follow the installation instructions.

! Certain technical skills are required to install the loudspeaker. Please have the product installed by a professional.

! AlphaTheta Corporation is not responsible for any loss or damage that results from improper installation, insufficient strength of installation materials, misuse,

modification or natural disasters.

Thank you for buying this product. Please read through these operating instructions so you will know how to operate your model properly. After you have finished reading the

instructions, put them away in a safe place for future reference.

Before you start

! Make sure to use amplifiers with rated load impedances that match the speaker impedance for the amplifiers connected to each loudspeaker.

! Furthermore, any devices or objects easily affected by magnetism (floppy disks, magnetic cards, magnetic tape etc.) should be kept well away from the speakers.

In order to prevent damage to the loudspeaker resulting from input overload, please observe the following precautions:

! If you supply amplification power to the loudspeaker excessively, the speaker could be damaged and overheating could cause a hazard.

! Only connect, turn ON or OFF the audio system or any one part (such as DJ player and Mixer) when the power to the amplifier is turned off. If any operations are performed

while the amplifier is turned on, there is the possibility of damaging the treble frequency speaker unit.

! When using a graphic equaliser to emphasise loud sounds in the high-frequency range, do not use excessive amplifier volume.

! Do not try to force a low-powered amplifier to produce high sound levels as the amplifier's harmonic distortion will be increased, and you may damage the speaker.

Caution: installation

! Ensure that the floor or stage surface can withstand the weight of the system.

! The installation technician must follow professional installation techniques to protect the loudspeaker against falling.

! Improper installation of the speakers could cause them to fall and cause damage or injuries to persons nearby.

! Do not attempt to stack devices together for use other than specified systems. Such devices may become unstable and tip over or fall, leading to injury. Make sure to

secure each device in place using the specified fixing hardware or other hardware to prevent them from tipping over or falling when stacking devices together.

AlphaTheta Corporation shall accept no liability for damage or injury caused by accidents resulting from AlphaTheta Corporation products tipping over or falling due to

them being insufficiently secured.

! Switch off and unplug your power amplifier and consult the instructions when connecting up components. Make sure you use the correct connecting cables.

! Keep magnetic objects such as screwdrivers or steel parts away from the woofer speakers. Since the speakers use strong magnets, the objects may be attracted, causing

injury or damaging the diaphragm.

! Do not install the loudspeaker in areas exposed to direct sunlight or near heating appliances. Such conditions may result in shrinkage of the wood materials and finish,

leading to deformation of the enclosure, discolouration, or damage to the speakers.

Conditions considered unpleasant by humans are detrimental to speakers as well. Providing a comfortable environment for the speakers will assist them in demonstrating

their best performance. Please maintain the usage environment as follows:

Temperature:

15 °C to 25 °C (59 °F to 77 °F)

Relative Humidity:

35 % to 65 % (winter)

40 % to 70 % (summer)

! Do not store speakers at temperatures outside of the rated temperature range as doing so may cause the speaker to drop in performance or become damaged.

Storage temperature range:

–20 °C to +55 °C (–4 °F to +131 °F)

! Do not use the product in locations subject to extreme fluctuations in temperature. Doing so could cause the product to malfunction.

! When using room air-conditioners or stoves to rapidly cool or heat room spaces, take precautions to avoid excessive dehumidification.

! Avoid placing the speaker near areas such as windows, as outside air can cause condensation to occur within the speaker.

! This loudspeaker is designed for indoor use only. To avoid electric shock hazard, do not place them outside, or in an overly humid area.

Caution: in use

! Do not use the speaker to output distorted sound for long periods of times. This can result in a fire hazard.

! Please also remember that vibrations from subwoofer systems can shake other loudspeakers out of place, which may present a toppling hazard.

! Do not attempt to use the product with the XY-218S grille detached as doing so could result in damage to the product. Consult a qualified professional for assistance with

removing the grille for maintenance purposes.
