Installing the loudspeaker
The CHA530/660 horn loudspeakers are designed for use in 100 Volt public address
systems. Before connecting the loudspeakers to the system, make sure the amplifier
is switched off.
A 5-pin waterproof AWX-5 connector is located on the rear cover of the speaker, allowing
connection to the amplifier output using the included connection cable (AWC07) with a
length of 0.7 meter. The blue conductor shall always be connected to the COM terminal of
the amplifier output and red conductor shall always be connected to the positive terminal
of the amplifier output. Mind the polarity markings when wiring the loudspeaker cables.
The power tap selection is made by adjusting the rotation angle of the waterproof con-
nector. A dot on the connector indicates the direction of the connector and the various
power tappings are indicated on a label attached to the speaker and in the image below.

When mounting the speaker to any wall or ceiling, make sure the mounting surface can
structurally support the weight of the speaker and the appropriate fasteners are used
depending of the mounting surface. (brick, wood, concrete, ...)
