Based on the 3rd Generation circuit design of our celebrated RPQ3, the RPQ503 brings the same rich and natural sound to the 500 Series Format.
Your Favorite Ribbon Preamp — Now in 500 Series
The RPQ503 is the next evolution in AEA’s trusted lineage of high-impedance, high-gain preamplifiers.
More than just a preamp, the RPQ503 also includes the expanded EQ section of the RPQ3, with boost and cut controls for both low and high end, on custom, compact, dual-concentric potentiometers.
Featuring a powerful combination of ultra-low noise, low-distortion op-amps, ultra-high 68KΩ input impedance, and 85dB of clean gain, the RPQ503 delivers exceptional clarity and detail.
Enhance every microphone
A gain powerhouse
The RPQ503 is a powerhouse that provides unparalleled high gain with low-noise. With 85db of clean gain, the RPQ503 gives you enough juice to record soft sources without ever having to worry about noise. The RPQ503 is the tool of choice for all microphones whenever a true and pristine signal path is desired. Our 3rd generation circuitry is the cleanest and most musical design we’ve done yet.
