Pressure chamber loudspeaker

100V Technology 

The weatherproof pressure chamber loudspeaker models for use in communication, public address or evacuation systems with 100V technology are ideally suited for speech transmission and speech alarming, even in acoustically difficult environments, due to their outstanding speech intelligibility.

They are suitable both for indoor and outdoor use. The grey plastic housing is made of self-extinguishing PC/ABS and is therefore resistant to environmental influences. Due to the processed material the pressure chamber loudspeakers withstand extreme temperatures and are equipped with a stainless steel swivel-tilt mounting bracket for flexible wall and ceiling mounting.

For cable entry, the pressure chamber loudspeakers are equipped with two M20 cable glands each. The connection cables are connected internally to a 4-pin terminal. The delivery includes matching transformer, mounting material and a tuned high-pass filter.
