Bosch introduces a full range of volume controls and program selectors to provide a complete public address solution

Functions

Operation

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

In the event of an (emergency) announcement, the built-in relay ensures that the message is broadcast at a preset level, independent of the local volume setting

The volume controls come in three versions according to power rating:12W, 36W,and 100W

The total load of the loudspeakers connected to a volume control may not exceed the rated power

Each of the three versions is also available in two versions

One is a power-saving,4-wire volume override (/10 models),where the override relay is activated during an emergency call

The other is a failsafe,4-wire volume override (/20 models),where the override relay is deactivated during an emergency call

The design and color are unobtrusive in any interior

Ease of installation, operation and reliability is optimized in the design
