The CSB range of speakers consists of a series of 4 models CSB-20T and CSB-40T, which have a modern design and quality sound. They are available in black or white and are suitable for indoor use. They are certified according to the European standard EN 54-24 / 2008 for public address and fire alarm systems. They are equipped with a 3-inch or 4-inch wideband speaker and their large frequency range are also suitable for music transmission. Power is 20W or 40W. The speakers contain low-frequency transformers and allow connection to high-impedance distribution of 70V and 100V, or the speaker can be connected by bypassing the transformer (Bypass), then they have an impedance of 4 or 8 Ω. The rotary switch on the back of the speaker (under the cover) can be used to select the taps of the transformer and thus reduce the volume (power) of the speaker. Mounting is performed using an articulated bracket with wall mounting with the possibility of turning in the required direction. The speaker case is made of ABS resin and is resistant to scratches and shocks.
