High-gain, high-impedance, 2-channel, full-rack preamp with EQ & DI
- Two channels with 81dB of sweet and quiet JFET gain
- High frequency CurveShaper™ EQ and low frequency proximity control
- NoLoad™ 63k ohm high-impedance circuitry providing better overall transients, frequency response, and higher output sensitivity
- High-resolution, high-impedance front-panel 1/4″ DIs
- Mic/Line mode with Post-Mic and Pre-EQ Inserts for alternative and convenient routing options
The AEA RPQ2 Ribbon Preamp and EQ provides two channels of high-quality, high-gain, low-noise preamplification with a rich and musical sound that complements the natural tonality of your microphone. Specifically designed for ribbon microphones, the RPQ2 excels at drawing out the warmth and lush sound that ribbons are uniquely known for. With 81dB of gain, JFET circuitry, and an input impedance of 63K Ohms, the RPQ2 delivers the precision, quietness, and headroom needed for today’s high-resolution recordings.
The RPQ2 is AEA’s second iteration of the high-performance RPQ preamp with the addition of some new and useful features. It is now possible to plug your instrument directly into the RPQ2’s high impedance circuit with its front-panel direct inputs. The RPQ2 also includes a Mic/Line switch for balanced line inputs and outputs, as well as inserts for patching compressors or other effects between the preamp and CurveShaper™ EQ section. The RPQ2’s CurveShaper™ EQ gives you the tools to control your ribbons right at the start of the signal path. Switchable and tunable low frequency (LF) and high frequency (HF) controls allow you to tame proximity problems and provide high-frequency extension and slope control.
Engineers have discovered that the RPQ2 is a perfect fit with condensers and moving coil microphones. By virtue of its sonic qualities and versatility, the AEA RPQ2 is the tool of choice for all microphones whenever a true and pristine signal path is desired. Detailed and accurate, the AEA RPQ2 is a high-quality, high-gain choice for all microphones.
Two Peas in a Pod: Musical Preamp, Sweet EQ
The CurveShaper’s™ high-frequency filter boost enables you to add a little extra “presence” or “air” to your source. The circuit functions in a similar manner to a conventional parametric shelving boost, but with a significant difference: the slope varies as both the CurveShaper™ and HF Gain controls are adjusted. This unique bell curve was designed with the intention to compensating for the high-frequency roll-off that is inherent to most ribbon microphones. But beyond ribbon mics, the smooth HF filter is remarkably well suited for brightening up condenser microphones used at a distance, restore presence in overly “dry” acoustical environments, or even as a clean and transparent air-band boost on the 2-bus.
The CurveShaper’s™ low-frequency control easily removes boxiness and boominess in a fast and unobtrusive way. Ribbon microphones are capable of delivering strong subwoofer lows, and can have a significant bass proximity effect. Such strong low-frequency content can mask high-frequency intelligibility, so the tunable LF filter was engineered to tame low-frequency energy to appropriate levels. Its -20dB shelving curve is ideally suited to reduce excessive proximity effect, opening up new possibilities to use ribbons in close-up applications.
