Introduction
The AUDAC SP20 is an unidirectional and humidity proof sound projector with a high efficiency. It is
suitable for speech and music and ensures a powerful and high quality sound reproduction.
It features a 5” full range speaker and a built-in 100 Volt line transformer with four different power
taps, to be used in large 100V PA applications.
The enclosure is made of white weatherproof ABS with a aluminum front grill and a special
weatherproof coating.
The mounting of the speaker should be done by means of the stainless steel mounting bracket, and a
75 cm cable is provided for connecting the loudspeaker.

1) Before mounting the loudspeaker, make sure that the speaker can be mounted on a safe location and
can be easily aimed to the desired location.
Also make sure that the mounting location (Wall / Ceiling) is solid enough to support the weight of the
loudspeaker.
2) The speaker should be mounted using the included U-shaped mounting bracket. Depending on the
mounting surface, the appropriate fasteners should be used (wood, concrete, steel, …).
3) For mounting the speaker more easily, the mounting bracket can be removed by means of the two
bolts on the side.
4) When the U-shaped bracket is mounted on the desired location, the speaker can be installed to the
mounting bracket by means of the two fixing screws on the side.
5) After the loudspeaker is mounted on the desired location, the connections can be made.
