Technical Notes
Safety steels may be used only with the M10 threaded inserts. M6 or M8 threaded
inserts in the rear are to be used exclusively with DAL original accessories or are
designed as lashing points. A
ft
er use, make sure that the countersunk screws
belonging to the cabinet are screwed back into the threaded sleeves in order to
maintain an air-tight system.
DAL protective grilles with foam lamination are the mechanical protection
component for the built-in transducers and o
ff
er a high acoustic transmission as
well as their a
ff
ixing minimizes sonic influences of the grilles. The backing or
covering of the grilles with foam serves also as UV-light protection, dust
protection and improves the optical unobtrusive of the systems. Only
undamaged grilles and foams can fulfil these tasks. Replace warped grilles or
worn foams to maintain their function.
By turning the hi-driver/horn unit in the S10N-TM80cabinet, you change the
horizontal and vertical acoustic radiation characteristics of the system. First
remove the protective grille. To do this, remove the M4 TX20 countersunk screws
on top and bottom and clear away the grill. Remove the 4 M4 TX20 screws of the
hi-driver/horn unit. Pull the Hi-Driver/Horn unit a few centimetres out of the
cabinet and turn it by 90°. Refit the Hi-Driver/Horn unit, taking care to ensure an
airtight seal in the groove. Then attach the protective grille back. Mark the
loudspeaker with the changed radiation pattern.
DAL loudspeaker systems with polyurea-coated or painted enclosures are
basically suitable for temporary outdoor operation, even in the rain.
For indefinite operation outdoors as in fixed installations, the loudspeaker
systems must be protected with a hood against direct sunlight and rain. If
necessary, the loudspeaker should be equipped with the optional front grille with
weather protection.
Most DAL loudspeaker systems can be supplied for extra charge from the factory
in a weatherproof (WR) or sea-weatherproof (SWR) variant.
For indefinite operation outdoors in subtropical and tropical areas, the
loudspeaker should be ordered as the WR variant. For indefinite operation at sea
and other areas with a humid and salty atmosphere, the loudspeaker should be
ordered in the SWR equipment variant. Both variants are manufactured at the
factory only.
