Description

AEA RPQ503 – 500 Series Mic Preamp & EQ

OVERVIEW

The RPQ503 is the next evolution in AEA’s trusted lineage of high-impedance, high-gain preamplifiers.

Based on the 3rd Generation circuit design of AEA’s celebrated RPQ3, the RPQ503 brings the same rich and natural sound to the 500 Series Format. 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. 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.

At once open and transparent but equally responsive and dynamic, the RPQ503 is a versatile tool for the front end of any signal path.

KEY HIGHLIGHTS

500 Series Format, Full-Sized Performance:

All the power of the RPQ3 packed into a single-space 500-series module for modern, modular workflows.

Built for Ribbons – Loved by All Mics:

With ultra-high 68kΩ input impedance, the RPQ503 is tailor-made for ribbon mics and shines with dynamics and condensers too.

Precision Sculpting with Expanded EQ:

Dial in your tone with +/-20 dB of shelving EQ on both lows and highs, using dual-concentric sweepable frequency controls.

Dead Quiet. Loud When Needed:

Enjoy up to 85dB of transparent gain, with virtually no noise – ideal for delicate sources or long cable runs.

Handcrafted in the USA:

Top-tier build quality and precision engineering, proudly made by AEA.

Expanded EQ Section

The RPQ503 expands on AEA’s signature CurveShaperTM circuitry, offering boost and cut curves for both bands of the EQ allowing users to control their sound right at the start of the signal path. With easy-to-understand controls and sweepable frequency knobs, the expanded EQ section of the RPQ503 offers boost and cut options for both lows and highs. Even when boosting aggressively, the RPQ503 remains flatteringly natural. When the EQ IN LED is illuminated, both LF and HF EQs are in the circuit. If you want to use only one band of EQ and not the other, simply turn the gain knob (the front one) of that pot to the center, which is detented.
