RCF PR 4093 Nine-Input Three-Output Preamplifier

RCF PR 4093 Nine-Input Three-Output Preamplifier

The RCF PR 4093 is a preamplifier for paging and music applications with six balanced microphone-line inputs and three stereo programme inputs. Its output arrangement includes stereo, mono and microphone paths, supporting routing to associated sound equipment.

The specified frequency response is 20 Hz – 22 kHz. The total number of audio inputs is 9. These characteristics define how the component fits into the supported audio arrangement and provide the starting point for selecting the associated equipment and operating settings.

The physical specification lists height 44 mm, width 483 mm, depth 195 mm, weight 2.8 kg. The enclosure material is Metal. The specified finish is Black. The product’s physical format should be considered alongside the installation position, the surrounding equipment and the space required to reach its connection points.

The amplifier should be selected around the connected loudspeaker load and the required source arrangement. Input compatibility, line configuration and available output power need to be considered together. This keeps the amplification stage aligned with the actual installation, whether the programme consists of announcements, background music or a combination of audio sources.

Plan the equipment position with room for the required connections and the specified ventilation arrangement. Establish the source routing and output settings before the system is put into service. Using the documented connection method keeps input levels, speaker loading and control functions consistent across the amplifier and the associated installation equipment. The final arrangement should follow the documented product configuration and remain matched to the intended system components. Consider the complete signal path when planning the position and connection of each component within the installation.
