  • Six Balanced XLR Mic/Line Inputs With Selectable Phantom Power For Condenser Mics
  • VOX-Activated Priority On Input 1 Interrupts Music For Automatic Paging
  • Three Stereo RCA Inputs Accommodate Consumer Playback Sources Alongside Mics
  • Dual AC And 24V DC Power Input Maintains Operation During Mains Failure
  • Three Independent Output Paths Enable Simultaneous Amp, Monitor, And Record Feeds
  • Front-Panel Tone Controls Allow Real-Time EQ Without Accessing Rack Interior
  • Convection Cooling Eliminates Fan Noise In Speech-Critical Installed Environments

The RCF PR-4093 is a 1U rack-mount preamplifier built for installed PA systems where reliable paging and background music routing are critical. System integrators and AV installers will find it well suited to commercial venues, houses of worship, educational facilities, and any fixed installation requiring structured input management across multiple sources. With six balanced XLR mic/line inputs and three stereo RCA line inputs, it covers both microphone paging stations and consumer playback sources in a single unit without requiring an external mixer.

The VOX-activated priority circuit on input 1 automatically interrupts background music when a paging microphone is live, making it directly applicable to retail, transit, and emergency announcement systems where manual muting is not practical. Front-panel tone controls on the XLR stereo output give the house engineer real-time EQ adjustment without accessing rack infrastructure. The three discrete output paths, covering XLR stereo, mono jack, and RCA record, allow simultaneous feed to amplifiers, a recording device, and a monitor chain without additional signal splitting. Convection cooling eliminates fan noise, which is a meaningful advantage in speech-critical environments where mechanical noise would otherwise compromise intelligibility.

The built-in 24V DC emergency power supply input keeps the unit operational during mains failures, a requirement in life-safety paging installations. CE compliance confirms it meets European safety standards, and the all-metal chassis holds up to the demands of permanent rack installation. For integrators comparing the PR-4093 to simpler mixer-amps or basic zone controllers, the combination of VOX priority, multiple output types, and DC backup in a compact 1U form factor makes it a practical choice for installations where reliability and routing flexibility cannot be compromised.
