FP-MP1

RDL FP-MP1 - Studio Quality Microphone Preamplifier with Phantom - Terminal Block & XLR

The RDL FP-MP1 is a professional studio-grade microphone preamplifier designed for AV installations, sound reinforcement systems, and studio environments. It features low-noise discrete circuitry for clean audio performance in a compact FLAT-PAK metal housing.

The unit offers four selectable gain ranges to accommodate microphones with varying output levels. Phantom power (12V / 24V) is switchable and compliant with IEC 61938:2013, making it suitable for condenser microphones. A built-in low-cut filter and dual LED level indicators provide precise control. XLR and terminal block connectors allow for flexible integration in both fixed and mobile setups.
