How do I mount the AP-30TC?

The speaker comes with a suspension cable and canopy. Secure the canopy to the ceiling, run the cable through, and attach to the speaker's mounting point. Adjust height as needed.

What is the frequency response of the AP-30TC?

It covers 70 Hz to 20 kHz, suitable for background music and paging.

Is the AP-30TC suitable for outdoor use?

No, it is designed for indoor use only. It is not weatherproof.

Can I paint the speaker to match my ceiling?

Yes, the enclosure is paintable. Use a compatible spray paint and avoid covering the driver.

What is the warranty on the AP-30TC?

Atlas Sound typically offers a 5-year limited warranty for this product. Check the documentation for details.

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.

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.

AP-30(T) Frequency Response

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. Electrolytic capacitors can be used but they must be non-polarized (See Typical Capacitor Values Chart).
