Bosch introduces a full range of volume controls and program selectors to provide a complete public address solution. Public address
systems are often used for both announcements and background music distribution. Volume controls can be used to adjust the level locally.
In addition to volume control, program selectors can also be installed to select five different programs locally. The design and color are
unobtrusive in any interior. Ease of installation, operation and reliability is optimized in the design.
