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.
Two-Band EQ Section
More than just a preamp, the RPQ503 includes an expanded two-band EQ section with intuitive dual-concentric controls. The EQ features sweepable low- and high-frequency bands with up to ±20 dB of boost or cut, allowing precise shaping of your signal right at the source. Whether you're dialing in warmth or taming rumble, the RPQ503 remains transparent, musical, and true to your source.
Versatile
The RPQ503 supports mic and line-level inputs, polarity switching, EQ bypass, and phantom power, all packed into a single-slot 500 Series module. A versatile, front-end tone-shaping tool, it excels with ribbons-and everything else.
