The mocha Bogen Communications HS7EZ is an Easy Design series 7.5W single-tap paging horn offering intelligible voice reproduction and versatile positioning for paging, talkback, and security applications in work sites, schools, parking lots, warehouses, and more. When connected to a 70V amplifier (available separately), it delivers a 7.5W output, a sound pressure level of 105 dB, and a frequency response of 250 Hz to 14 kHz. Volume is adjustable via a stepped attenuator control.

Its weatherproof, all-metal housing ensures reliable durability indoors and outdoors, and can be precisely tilted and swiveled using the sturdy mounting bracket. Banding slots allow mounting to a beam or pillar, and I-beam flange mounting is supported via the Bogen BC1 clamp (available separately). A 12" lead wire permits simple electrical connections to your 70V amp.
