Description The PR 4093 preamplifier is a compact and efficient audio control solution designed for public address and music distribution systems. It features 6 balanced XLR inputs with selectable MIC/LINE sensitivity and phantom power, plus 3 stereo unbalanced inputs via RCA connectors. Input 1 includes a priority function triggered by a VOX circuit, making it ideal for announcements. The unit provides 3 outputs: a stereo XLR with tone control (LOW, MID, HIGH), a mono jack output, and a dedicated MIC output. Additional outputs for recording devices are available on RCA connectors. Front-panel signal LEDs and output level indicators offer real-time status monitoring. With support for both 230V AC and 24V DC emergency power, the PR 4093 ensures continuous performance in critical applications.
