5. INSTALLATION
Read these instructions carefully before installing and using the product.
1. When the speaker is installed on ceilings, check that the structure is reliable
and the speaker is rmly attached.
2. Do not use nails, adhesives or other unauthorized devices. Long-term use
and vibrations may cause it to fall easily.
3. Do not place the speakers on a turntable or movable support.
4. Do not touch or bump the woofer. If these are damaged, the sound will be
distorted.
5. 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
amplier is turned o or master volume is at lower level.
6. Do not attempt to clean the speakers with chemical solvents as this may
damage the paint surface. Clean with a dry cloth.
5.1. Speaker Installation
The installer is responsible of installation. Please pay attention to
install speakers according to local safety regulations.
When mange these speakers, be careful not to touch or load the front
of the speaker net with hard facing, otherwise it will deform the net.
yStep1: Draw a ceiling hole on the ceiling with a diameter corresponding to the
ones shown on “4. PRODUCT APPEARANCE” at page 6.
yStep2: Use appropriate tools to open the mounting hole on the ceiling.

yStep3: Connect the speaker cable to the electric terminals (check “5.2. Speaker
Connection” at page 8).
yStep4: Fold the spring brackets with both hands.
yStep5: Insert the speaker into the ceiling and slowly release your hands.
5.2. Speaker Connection
GALA Series 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 amplier, 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-56W GALA-61W GALA-85W
Black Ground Ground Ground
Red 3W 5W 7.5W
White 6W 10W 15W
yConnect Black wires to Ground terminal (-) of the 70/100V amplier. Connect
White (full power) or Red Wires (half power) on (+) terminals of the 70/100V
amplier according to the number of speakers used, and the amplier power.
yIn 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 bass.
6. UNDER-POWERING VS OVER-POWERING
Most speaker damages are caused by ampliers with too little power (wattage).
Overdriven ampliers 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 amplier volume
until the distortion is no longer present. Damages caused by operating the speak-
ers at distorted volume levels are no covered by warranty.
6.1. Example of 70V/100V System Configuration
70V/100V
C
5 speakers connected in parallel using 6W Taps
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
6W tap position, you need an amplifier with at least 5x6=30W. A
good rule of thumb is to use an amplifier with 20% greater power; in
this case, an amplifier with 36W or more.
