- High-frequency CurveShaper™ EQ and low frequency proximity control
- Mic and line inputs for mixdown EQ versatility
- Switchable phantom power, polarity, line/mic, and EQ inserts
- NoLoad™ 10k Ohm high-impedance circuitry providing better overall transients, frequency response, and higher output sensitivity
- Made in the U.S.A.
ENHANCE YOUR RIBBONS - The AEA RPQ500 Ribbon Preamp and EQ provide two channels of high-output, high-impedance, and low-noise gain with a rich and natural sound that brings out the full potential of your microphones. Specifically designed for ribbon microphones, the RPQ500 excels at drawing out the warmth and lush sound that ribbons are uniquely known for. POWERHOUSE IN A 500 FORMAT - The RPQ500 is a powerhouse that provides unparalleled high gain with low-noise. With 81db of JFET output, the RPQ500 gives you enough juice to record soft sources without ever having to worry about noise. IT'S OH SO QUIET - With the RPQ500, you will never consider a source too quiet to record with a ribbon mic ever again. Passive ribbons with low output levels require preamps that supply a high level of output. If the preamp you use doesn’t have enough clean gain, the mic signal may seem too soft or noisy which may be apparent when recording quiet acoustic guitars or strings, especially at a distance or with long cable runs. The RPQ500 eliminates this concern. The CurveShaper EQ - The RPQ500’s CurveShaper™ EQ is a powerful tool that gives you the ability to control your ribbons right at the start of the signal path. Adjustable low and high-frequency controls allow you to tame proximity problems and provide high-frequency extension with slope control. The high-frequency filter boost enables you to add presence and air to your source –perfect for sources like ribbons and 2-busses that often benefit from some extra top-end. The low-frequency control easily removes bass build-up in a fast and unobtrusive way. The RPQ500 module, designed after the successful RPQ preamp, provides the same high-gain, high-impedance signal path that has earned AEA preamps their great reputation, but in a 500 series package.
HIGH IMPEDANCE MAKES A HUGE DIFFERENCE - The sound and tonality of dynamic microphones like ribbons and moving-coils are directly affected by the impedance of a preamp. The higher the impedance, the better the sound. The RPQ500 boasts an extra high input impedance of 10K Ohms. Preamps with an impedance of under 10k ohms will limit the lows, highs, and transients of your passive microphones. The RPQ500’s high impedance will reveal your microphone’s true nature– a thick low-end, open top-end, and articulate transient response that you will need to hear to believe. Both condensers and active microphones will also benefit from the RPQ500’s impedance.
Your Sound At Your Fingertips - The RPQ500 is a workhorse tool for your 500 rack. Many mixing and mastering engineers turn to the RPQ500 purely for its EQ functionality. The Line/Mic switch bypasses the microphone gain stage and allows the EQ to be used for tracking with other preamps or during mixdown. Add the output level control, and the RPQ500 becomes a high-quality processing tool that can be used for mixing and mastering when combined with summing racks and mixers such as the Purple Audio Moiyn or the Roll Music Folcrom.
