AEA Ribbon Mics RPQ503 500 Series Ribbon Preamp and EQ

The AEA RPQ503 brings the acclaimed sound of the RPQ3 to the compact and modular 500 Series format. Designed by Fred Forssell, the RPQ503 delivers up to 85 dB of clean, quiet gain with ultra-low noise and distortion—making it an ideal match for passive ribbon microphones. With its ultra-high 68-kilohm input impedance (phantom power off), the RPQ503 preserves the natural tone and detail of any mic it powers.
