AEA Microphones RPQ3 Microphone Preamp

AEA's RPQ3 microphone preamp is the next evolution of high-impedance, high-gain preamplifiers. Based on the circuit design of its predecessor, the RPQ3 features a powerful combination of ultralow noise, low-distortion op-amps, ultra-high 68 kohm input impedance, and 85dB of clean gain all packaged in a durable full-rack chassis. The RPQ3 also includes an expanded EQ section with boost and cut controls for low and high end as well as a low-end frequency sweep to identify and eliminate rumbles and resonances.Open and transparent but equally responsive and dynamic, the RPQ3 is a versatile tool for the front end of any signal path.Improved EQ SectionThe RPQ3 expands on AEA's signature CurveShaper circuitry that offers 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 user-friendly controls and sweepable frequency knobs, the expanded EQ section of the RPQ3 offers boost and cut options for both lows and highs. Even when boosting aggressively, the RPQ3 remains phase coherent and flatteringly natural. LF/HF LED indicators illuminate only when the EQ is engaged, eliminating confusion and simplifying workflow. The RPQ3 also has a +/-10dB gain range for increased accuracy in boosting and cutting.Power SwitchingThe RPQ3 chassis features open-back access to the AC power switch, making voltage conversion between U.S. standard 115V and 230V easy for setups anywhere in the world.
