APPLICATIONS
AP-15 and AP-15T environment-resistant loudspeakers are the world
standard for high-intelligibility voice and signal transmission in medi-
um-power indoor and outdoor public address, intercom, security and
industrial-signal-system applications. Cost effective, 15-watt units
incorporate high-efficiency compression drivers to project sound over
long distances or wide areas with fewer loudspeakers. The AP-15
Series is recognized throughout the world as "the performance stan-
dard" for commercial sound, intercom and protective-signaling sys-
tems. Units are commonly installed in commercial buildings, distribu-
tion centers, factories, schools, public access areas, civic centers and
recreational facilities.
GENERAL DESCRIPTION
The 8-ohm Model AP-15 and the transformer-equipped Model AP-15T
are double re-entrant loudspeakers which deliver 15-watts of continu-
ous power handling, superior intelligibility and unparalleled efficiency.
The AP-15 Series operates within a nominal frequency response
range of 400-14,000 Hz and offers a sensitivity of 120dB at rated
power to provide clear voice and signal communication.
Transformer-equipped Model AP-15T includes a versatile, 3-way, 25,
70.7, 100V line transformer to meet a variety of distributed system
needs. The transformer is adjustable using Atlas Sound's exclusive
Vari-Tap®Connect Center which features a 7-position,
watts/impedance selection switch. The labor-saving Vari-Tap
®switch
is screwdriver adjustable and includes a protective cover with built-in
cable strain relief.
The trademarked squared-bell design signifies Atlas Sound quality
and reliability. The Omni-Purposmounting bracket (supplied on all
models) achieves precise positioning in the vertical and horizontal
planes with a single adjustment and includes provisions for loud-
speaker installation on conventional surfaces as well as for strap-
mounting on I-beams or pillars. AP Series loudspeakers are U.S.
made to assure superior service reliability. Weather-resistant con-
struction is metal and matching ABS plastic with metal components
finished in grey epoxy (standard) or beige epoxy (Model AP-15TC).
The AP-15 Series also includes a 45-ohm Model AP-15-45 and a 4-
ohm AP-15-4 which are designed respectively for intercom and
CB/auxiliary radio applications. (See SL2-1567).

DRIVER PROTECTION: The horn loudspeaker should not be operated at
frequencies outside the specified range, especially below horn cut-off. It is sug-
gested that any program material be high-passed at 300 Hz with a 6dB per
octave filter. This can be done by a low level filter at the amplifier input or by a
series capacitor at each loudspeaker. Electrolytic capacitors can be used but
they must be non-polarized.
