RDL HR-MP2A Dual Microphone Preamplifier

For reliable, professional microphone gain control in security, surveillance and AV monitoring environments, the Radio Design Labs HR-MP2A Dual Microphone Preamplifier delivers clean, low-noise performance in a compact half-rack form. Each channel provides independent front-panel controls including a -15 dB INPUT PAD that increases maximum input capability to over +20 dBu and continuous GAIN adjustment from 20 to 60 dB, so operators can tame loud sources or boost quiet mics without introducing hiss. Line-level outputs and a POLARITY switch make integration with recorders, mixers and monitoring systems straightforward, while the CLIP LED indicates peaks within 3 dB of clipping to prevent distortion during critical surveillance captures. With a broad 10 Hz–70 kHz frequency response and 24 V DC operation, the HR-MP2A maintains audio fidelity for voice, ambient sound and forensic recording. Ideal for security consoles, facility monitoring racks, broadcast and AV installations, this Radio Design Labs preamplifier gives technicians precise control over microphone signals. Add the HR-MP2A to your rack to improve clarity and reliability in monitoring and surveillance applications.
