JBL CSS-H30 30W Paging Horn with 70V/100V Transformer

The JBL Commercial Solutions Series CSS-H30 Paging Horn provides excellent voice range clarity for public address systems, announcement/paging, intercom, security, alarm and industrial applications.  Designed for demanding environmental conditions, the CSS-H30 is highly weather resistant (IP-65 rated) so it can be used in either indoor or outdoor applications.  The focused coverage pattern allows the horn to project the sound a farther distance than is the case with wider-coverage paging horns.  Typical applications for this product are public access areas, warehouses, factories, schools, recreational facilities, commercial buildings, distribution centers, civic centers, and other commercial sound and protectivesignaling systems.

The CSS-H30 includes a UL-registered 30-watt multi-tap transformer for use with 70V or 100V distributed speaker lines.  The power tap switch is screwdriver adjustable for easily changing settings from 30W, 15W, 7.5W, 3.8W (and 1.9W at 70V only).  For non-distributed systems there is an 8 ohm bypass position.  Connection is via bare wire on a built-in jacketed cable with water-tight entrance to the speaker.

The transducer diaphragm is sturdy phenolic material to enhance durability, especially in outdoor applications, and to resist deformation under stressful temperature conditions.  To further increase reliability, a 350 Hz high-pass filter is built-in to protect the paging horn against damage from frequencies below the operational frequency band.  The horn is constructed from sturdy ABS plastic and exterior hardware is corrosion-resistant stainless steel.  A stainless steel mounting bracket is included.
