Bosch introduces a full range of volume controls and program
selectors in order to provide a complete PA solution.
Public address systems are often used for both announcements and background music distribution. In order to adjust the level locally, volume controls can be used. In case of an (emergency) announcement the builtin relay can be activated to ensure that the message gets across at full level, independently of the setting of the
volume control. The total load of the loudspeakers connected to the volume controls may not exceed its rated power. Next to volume controls also program selectors can be installed to select different music programs locally. The design and color are unobtrusive in any interior. Ease of installation, operation and reliability has been optimized in the design. The U40 version volume controls and program selectors can be combined with Gira standard 55 system switchers and accessories. For surface mounting of U40 and MK types of volume control and program selector, an optional surface mounting box is available.
