Shure FP16A Distribution Amplifier

The Shure FP16A is a professional 1-in, 6-out audio distribution amplifier designed to take a single microphone or line-level signal and provide multiple, isolated, and buffered outputs for routing to various destinations. Its primary function is to solve a common problem in audio systems: splitting a critical signal—such as a podium microphone, main program feed, or recorded playback—to multiple consoles, recorders, broadcast feeds, or processors without signal degradation, ground loops, or loading issues. The unit provides complete electrical isolation between its outputs, ensuring that a problem on one downstream device (like a short or different grounding potential) does not affect the signal sent to any other connected equipment.

Engineered for reliability in permanent installations and broadcast environments, the FP16A features a robust metal chassis with a half-rack width, making it ideal for space-efficient mounting in equipment racks. It accepts a balanced input via an XLR connector and provides six identical, transformer-isolated balanced outputs, also on XLR connectors. This design preserves signal integrity over long cable runs and in electrically noisy environments. The amplifier includes a front-panel gain control with up to 20 dB of adjustable boost, allowing it to match levels between different types of source equipment and destinations, and LED indicators for power and signal presence.

The FP16A is a fundamental, set-and-forget component in professional audio infrastructures, commonly found in houses of worship, conference centers, broadcast facilities, and performing arts venues. By providing clean, duplicated signals from a single source, it simplifies system design, increases flexibility, and enhances overall system reliability. It ensures that a critical audio source can be simultaneously sent to front-of-house and monitor consoles, recording devices, streaming encoders, and assistive listening systems with consistent, high-fidelity quality.
