4. INSTALLATION

The special hexagonal shape of the cabinet makes it possible to

position the speaker in various way, as shown in the figure. The

EAW Commercial plate on the front protective grille can be rotated

to adapt it to the position of the speaker. The speaker body has

four M6 threaded inserts, one each on the top and bottom and

two on the back, used for attaching accessories for installing the

speaker in different ways.

The SMS4 (SMS4W) loudspeakers are supplied with a black

(white) ball joint support for wall mounting.

WARNING: Consult a professional rigger or structural

engineer prior to suspending loudspeakers from a

structure not intended for that use. Always know

the working load limit of the structure supporting

the loudspeaker array. Always make sure that the

rigging hardware minimum rating is at least five

times the actual load.

insulation off the end of the speaker wire, press in the tab, and

wire is locked in place. Make sure there are no stray strands of

wire outside the terminal connection.

WARNING: To prevent the risk of electrical shock,

always fit the protective cover of the terminals after

completing connections.
