Read these instructions carefully before installing and using the

product.

When the speaker is installed on ceilings, check that the structure is reliabl and the speaker is firmly attached.
Do not use nails, adhesives or other unauthorized devices. Long-term use and vibrations may cause it to fall
Do not place the speakers on a turntable or movable
Do not touch or bump the If these are damaged, the sound will be distorted.
Do not listen to sound at a very high level when you are changing the input source (for example, from FM Tuner to CD player). Please be sure the power amplifier is turned off or master volume is at lower
Do not attempt to clean the speakers with chemical solvents as this may damage the paint Clean with a dry cloth.

Speaker Installation

The installer is responsible of installation. Please pay attention to install speakers according to local safety regulations.
When handling the loudspeakers, be careful not to touch the front of the net, otherwise there is a risk of deforming it.

Step1: Draw a ceiling hole on the ceiling with a diameter corresponding to the ones shown on “4. PRODUCT APPEARANCE” at page 6.
Step2: Use appropriate tools to open the mounting hole on the
Step3: Remove the speaker grille by using the special tool (supplied).
Step4: Connect the speaker cable to the electric terminals (check “5.2. Speaker Connection” at page 8).
Step5: Insert the speaker into the Rotate the mounting screw clockwise
Step6: Install the speaker

Speaker Connection

GALA-520DW speakers are equipped with a built-in line transformer with 2 power taps, to better adapt each speaker to the type of line (constant voltage @ 70V or 100V), the power of the amplifier, and the number of speakers in the system.

When connect the speaker to the 70/100V line, pay attention to wire colors. Please refer to the following table when connect them to the line.

Wire Color	GALA-520DW
Black	Ground
Red	10W
White	20W

Connect Black wires to Ground terminal (-) of the 70/100V Connect White Wire (full power) or Red Wire (half power) on (+) terminal of the 70/100V amplifier according to the number of speakers used, and the amplifier power.
In case of parallel speaker connection, please make sure that there is not in- verted polarity (+ connected to -). If the polarity of the speakers is reversed, the sound will be unnatural and will play without

UNDER-POWERING VS OVER-POWERING

Most speaker damages are caused by amplifiers with too little power (wattage). Overdriven amplifiers clip output waveforms and send distortion to the speakers. Clipping is usually audible; it may vary from a harsh sound to a fuzzy or unclear sound.
If you hear this condition at loud volume levels, turn down the amplifier volume until the distortion is no longer present. Damages caused by operating the speak- ers at distorted volume levels are no covered by warranty.

Example of 70V/100V System Configuration

NOTE: Total number of speakers multiplied by tap value cannot exceed the output power (in watts) of the 70V/100V amplifier. The above examples shows 5 total speakers in a 100V system. If you use 20W tap position, you need an amplifier with at least 5×20=100W. A good rule of thumb is to use an amplifier with 20% greater power; in this case, an amplifier with 120W or more.
