Introduction
With the standard sound projector you have acquired a humidity proof unidirectional sound projector
with high efficiency. The SP20 is suitable for speech and music thanks to its high-quality and powerful
sound reproduction.
The enclosure is made of white ABS with a metal grille, including a metal bracket for easy wall mounting.
The SP20 features a 4” full range speaker with a built-in 100V line transformer, with tapping for 20 W,
10W, 5 W or 2,5 W.
Warning
Only use the correct amplifier output voltage and impedance, exceeding these limits could cause fire or
other failures.
Avoid explosions: do not use the speaker around gasoline, thinner or other combustibles.
Only install the speaker in locations that can structurally support the weight of the speaker and the
mounting bracket. Not doing this may result in the speaker falling down.
Do not use any other method than specified to mount the bracket. If extreme force is applied to the
speaker,
it could fall down.
Attach a safety wire to the speaker when it is mounted high above the ground. Failure in doing so could
cause the speaker to fall down for any reason (safety wire not included).
Avoid mounting the speaker in locations exposed to constant vibrations. The mounting bracket can be
damaged by excessive vibration, potentially causing the speaker to fall down.

Caution
Avoid electric shocks: switch off the amplifier power when connecting the speaker.
Avoid installing the speaker in locations exposed to solvents, acids, smoke and heaters, as excessive
exposure to these factors could result in speaker failure, fire or electric shock.
Do not operate the speaker for an extended period of time at distorted sound. This could cause
(irreparable) damage to the speaker.
Do not stand or sit on it, nor hang down from the speaker as this may cause it to fall down or drop.
Installation
Install the speaker in an appropriate location with the mounting bracket. Tighten them with nuts and
bolts.
To adjust the directivity of the speaker, you loosen two bolts at the sides of it and then position it.
Afterwards tighten the bolts firmly.
Connections
??????????
Be sure to use the following polarities when using several speakers in the same location.
The total rated input of all connected speakers may not exceed the amplifiers output.
