6. Select power
Using a flat-bladed screwdriver, rotate the Tap Selector
so the correct power setting is adjacent to the arrow. Note
that there are separate 70V and 100V scales, depending
on the amplifier being used (see diagram 7).
The transformer may also be by
passed by selecting the PS position.
It may be desirable to leave the grilles
off until commissioning is completed
if adjustments are likely to be needed.
7. Fit grille
Carefully insert the perforated grille into the speaker body and press in firmly.
To prevent the grille from vibrating loose, ensure that it is fully pressed in.
5. Install speaker
Insert pre-wired connector, ensuring correct polarity.
Attach secondary support to the tab, if required by local building regulations.
Lift speaker into hole and tighten the 4 mounting tabs using a screwdriver (see diagram 5,6).
Do not over-tighten.
CAUTION: To avoid distortion or equipment damage, carefully consider the
power ratings of both amplifiers and speakers.
Only 2 speakers at 60W will fully load a 120W amplifier, but note that each
will be producing more than 106dB direct Sound Pressure Level at the listener
when installed in a 3m ceiling! Dropping to the 15W tap allows 8 speakers
to be driven by the same amplifier, each producing 100dB SPL.
If 60W @ 70V is selected, but 100V line amplifier is connected, the speaker
will draw up to 120W and damage is likely.
