Introducing the New AEA RPQ503 500-Series Microphone Preamp! AEA has just announced the newest addition to their series of preamps, the Introducing the New AEA RPQ503 500-Series Microphone Preamp. AEA makes some of the finest microphones in the world and they certainly know what makes a great microphone preamp. The RPQ503 is essentially a 500-Series version of their popular 19-inch rackmount preamp, the AEA RPQ3 Ribbon Microphone Preamp. 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.

AEA RPR503

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. The RPQ503 expands on AEA's signature CurveShaper 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.
