Bosch provides a full range of volume controllers and sound

 source selectors to achieve a sound public address solution. Basic function operation public address system is usually used for information and background music transmission. The volume controller can be used to adjust the volume level locally. In addition to the fader, a sound source selector can be installed to allow local selection of five different sources. When a (emergency) broadcast is required, the built-in relay ensures that the message is broadcast at a preset volume level, regardless of the local volume setting. Depending on the rated power, the fader is available in three models: 12 W, 36 W and 100 W. The total load of the speakers connected to the fader must not exceed the rated power. In addition, the three models are available in the following two versions. One is the power-saving 4-wire volume coverage Version (/ 10 models), which activates the coverage relay in the event of an emergency call. The other is the fail safe 4-wire volume override Version (/ 20 model), which deactivates the override relay in the event of an emergency call. The design and color of the fader can be perfectly integrated into any indoor occasion. In addition, in the design process, the installation simplicity, operation convenience and reliability are optimized.
