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, modifi
-
cation 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 per
-
formed while the amplifier is turned on, there is the possibility of damaging the treble frequency speaker unit.
!
When using a graphic equalizer 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, wall, ceiling, or stage surface can withstand the weight of the system.
!
The installation technician must follow professional installation techniques to protect the loudspeaker against falling.
!
When installing the speakers, make sure that the wall/ceiling is strong enough to support the speakers.
!
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 pole mount, ratchet straps 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 this products tipping over or falling due to them being insuffi
-
ciently 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 tweeter and 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 demonstrat
-
ing 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 or falling hazard.
!
Do not attempt to use the product with the XY-1 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.
!
If you notice anything unusual with a speaker or ceiling suspension hardware, immediately stop using it and detach it without delay.
!
If you notice cracking on the speaker enclosure, immediately stop using it and detach it without delay.
!
Detach speakers that are not used or cannot be used without delay.
!
To prevent the risk of electric shock, do not remove cover (or back). No user-serviceable parts inside. Refer servicing to qualified service personnel.
