Rotary volume controller Omnitronic 80711091

The Omnitronic 80711091 is a wall-mountable rotary volume control and PA program selector designed for precise adjustment of public-address audio levels. It accepts up to 24 V input and supports audio handling up to 30 W with a frequency response of 50–18,000 Hz. The compact housing (80 mm × 67 mm × 154 mm) is intended for seamless integration in fixed installations where local volume control and program selection are required.

Advantages

This unit combines a rotary volume control with a PA program selector and includes a 24 V emergency priority relay for automatic override of normal audio when needed. Its wide frequency range maintains clear speech and music reproduction across typical PA applications, while the 30 W power handling suits small to medium distributed speaker lines. Wall-mount design and standard dimensions simplify installation in control rooms, corridors, classrooms, or service areas.

How to use

Mount the unit on a suitable wall surface and connect the audio input and speaker outputs according to the system wiring diagram.

Recommendations

Place the Omnitronic 80711091 near typical user access points (corridors, entrances, or control panels) for convenient operation. Use within the specified 30 W power limit and within the 50–18,000 Hz frequency range to avoid distortion. When integrating emergency priority, follow local safety regulations and test the relay function as part of regular maintenance.
