Heinrich's OHS20/T is a waterproof horn speaker with a built-in 70V/100V transformer. In addition to reducing line losses over long distances, the 70V/100V transformer technique allows multiple loudspeakers to be connected in parallel and to having a wide frequency response of 250Hz-8KHz, the built-in horn speaker driver also offers multiple power taps of 10W and 20W @100V to suit various applications depending on room size and ambient noise. It is easy to wall mount and comes with an ABS enclosure and a white metal bracket for secure installation. The speaker's opening angle is 90 degrees to 30 degrees, allowing it to provide a wide range of sound coverage. It is perfect for outdoor applications, such as parking lots, parks, gardens, corridors, and playgrounds.

All products comply with the LOW VOLTAGE DIRECTIVE (BS EN 60065, 2003, IEC 60529) and EMC (BS EN 61000-6-Part 1/2/3/4).
