General Description
The DLS4 was specially designed for optimum use in low ceiling
paging and background music applications where wide dispersion, high
efficiency and ease of installation are required. The DLS4 is perfectly
suited for use in airports, rail stations, retail stores, and hospitality
applications.
The system consists of a 4" high efficiency driver. A unique (patent
pending) tap selector switch design allows for easy system tuning. A
full selection of taps up to 8 Watts as well as an 8
Ω
bypass setting
is included for maximum system versatility. This switch “knob” also
functions as a diffuser cone, providing smooth, even dispersion of the
high frequency content from the center of the 4" driver. In fact, the high
frequency response of the DLS4 is so natural that many would assume
that the driver in the DLS4 was a coaxial design instead of a cone driver.
The easy to use DLS4 “dog leg” mounting system works with several
popular Atlas Sound hardware combinations for use in new or existing
drywall or acoustic ceilings with or without conduit! For mineral tile
applications the popular FA81-4 tile bridge has been equipped to allow
“twist lock” installation of the economical CS95-8.
Suggested Mounting Hardware:
Mineral Tile - no enclosure - FA81-4 Tile Bridge
Mineral Tile - with enclosure - FA81-4, CS95-8
Drywall Ceiling new construction - no enclosure - FA-TR4
Drywall Ceiling new construction - with enclosure - FA-TR4, E410NT
The DLS4 will also retro-fit into existing E410 & E410-11 enclosures.
(Torsion tabs inside enclosure must be bent inwards to allow for
complete clearance of the DLS4 dog leg mounting system)
