Overview
The Visaton 1803 is a signal transformer designed for public address loudspeaker systems. It operates with a 100 V primary voltage and supports multiple secondary impedances of 4, 8, and 16 ohms. The device provides an audio frequency response range from 50 Hz to 19,000 Hz. This component facilitates impedance matching and voltage distribution in professional audio installations.
Feature Summary
- Supports multiple secondary impedance options including 4, 8, and 16 ohms
- Designed specifically for integration into 100 V line PA systems
- Provides wideband audio frequency response suitable for speech and music
Applications
- Public address system loudspeaker integration
- Commercial audio installation wiring
- Multi-zone speaker distribution networks
Procurement Notes
Verify the specific datasheet version when sourcing, as technical documentation may be updated. Confirm that the required secondary impedance matches the load requirements of the connected loudspeakers. Ensure compatibility with the 100 V constant voltage line architecture typical of professional audio infrastructure.
Selection Notes
Select this transformer based on the need to step down 100 V line voltage to low impedance loads. Choose the appropriate secondary tap corresponding to the speaker's rated impedance. Consider the frequency response limitations at the upper end when evaluating suitability for high-fidelity music reproduction versus voice-only applications.
Part Context
Visaton GmbH & Co. KG manufactures specialized audio components for professional sound reinforcement. The 1803 belongs to their series of signal transformers used to interface between amplifier outputs and distributed speaker arrays. These components are essential for maintaining signal integrity over long cable runs in fixed installations.
Replacement Considerations
No publicly confirmed substitute part numbers are available in the provided documentation. When replacing, ensure the new component matches the 100 V primary specification and offers compatible secondary impedance taps.
