APPLICATIONS
All-purpose, environment resistant 30-Watt AP-30 Series loudspeakers provide cost effective high-intelligibility voice and signal
transmission for high power indoor and outdoor public address,
intercom, security, alarm, or industrial signal systems. Units incorporate high-efficiency compression drivers to project through high
ambient sound levels, over long distances and in wide open areas
with fewer loudspeakers. The AP-30 Series is renowned in the
industry as the "professional standard" for applications such as
commercial buildings, distribution centers, industrial warehouses,
institutions, civic centers and recreational facilities.
GENERAL DESCRIPTION
The 8-ohm Model AP-30 and transformer-equipped Models AP-30T
and AP-30T-25 are double re-entrant loudspeakers which deliver 30
watts of continuous power handling, superior intelligibility and
unparalleled audio conversion-efficiency. The AP-30 Series operates within a nominal frequency range of 300-12,000 Hz and offers
a sensitivity of 126dB at rated power to provide clear voice and signal communication.
Models AP-30T and AP-30T-25 each feature an integral transformer
to meet a variety of distributed system needs. The AP-30T is
equipped with a versatile, 3-way, 25, 70.7, 100V line transformer,
while Model AP-30T-25 includes a 25V only line transformer.
Transformers are adjustable using Atlas Sound's exclusive Vari-Tap
®
Connect Center which features a 7-position, watts / impedance selection switch. The labor saving Vari-Tap terminal is screwdriver
adjustable and includes a protective cover with built-in strain relief.
The trademarked square bell design signifies Atlas Sound quality
and reliability. The Omni-Purpose mounting bracket (included on all
models) allows precise positioning in the vertical and horizontal
planes with a single adjustment and provides for installation of the
loudspeaker on conventional surfaces or by strap-mounting to
I-beams or pillars. AP Series loudspeakers are U.S. made to assure
superior service reliability. Weather-resistant construction is metal
and matching ABS plastic with metal components finished in grey
epoxy (standard) or beige epoxy if suffixed with (C) where noted.

DRIVER PROTECTION:
The horn loudspeaker should not be operated at
frequencies outside the specified range, especially below horn cut-off. It is suggested 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 (See Typical Capacitor Values Chart).
