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.

Installation procedure

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.

Connections

To avoid electric shocks during installation, always switch of the amplifier power when connecting

loudspeakers.

A 5 core connection cable is provided on the rear side of the loudspeaker. By connecting the

appropriate cable cores, the desires power taps for the loudspeaker can be selected, to be used in 100V

public address applications.

Connections for 100 Volt use:

COM Black

20 Watt Red

10 Watt Yellow

5 Watt Blue

2.5 Watt Green

Always connect the – pole of the amplifier output to the COM (Black core). The + pole of the

amplifier can be connected according to the table above for the desired output power.

When the loudspeaker is connected to 70.7V facilities, the power indicated in the table above will be

reduced to half the power, and when connected to 50V facilities, the power will be reduced to a quarter.

When the desired power tap is selected and connected, the loudspeaker is ready to be used.
