The RCF PR 4092 is a versatile preamplifier designed to offer flexible solutions for various paging and music applications in PA systems. With nine balanced XLR inputs, including eight inputs with both microphone and line sensitivity, this preamplifier provides exceptional versatility for different audio sources.

Designed with convenience and functionality in mind, the PR 4092 features input/output selectors for each input, allowing users to route signals to output A only, output B only, or both A and B. This unique design enables the unit to function as a double preamplifier, with output A dedicated to paging and output B for background music programs.

Priority functions are seamlessly integrated into the design, with input 1 having overall priority for paging purposes. Inputs 2 and 3 can be set with priority over inputs 4 to 9, ensuring smooth and efficient management of audio signals. The priority function only affects the selected output, leaving the other output unaffected.

In addition to its prioritization features, the PR 4092 offers switchable 12V phantom power and hi-pass filters on universal inputs, providing further customization and control over audio signals. Each input is equipped with a signal presence indicator for easy monitoring and troubleshooting.

The preamplifier also includes four inputs available on RCA stereo type connectors, offering additional connectivity options for various audio devices. A three-tone chime generator, triggered by contact closure, adds convenience for paging announcements.
