The AEA RPQ Ribbon Preamp with Curve-Shaping provides two channels of high-quality, high-gain, low-noise microphone preamplification, and unlike the TRP provides phantom power for active electronics. Particularly well-suited for use with ribbon microphones, it delivers the speed, precision, quietness, and headroom needed for today's high-resolution recordings. The JFET circuit design generates up to 80 dB of clean and quiet gain, with extended bandwidth from below 1 Hz to beyond 200 kHz, for dynamic range and transient response that complements all of your microphones.

The RPQ's Curve-Shaper gives you the tools to control your ribbons. Ribbon mics are capable of delivering strong sub-woofer 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.

The HF filter enables you to extend the high end adding a little extra "presence" or "air" to the pickup. The HF filter compensates for the high-frequency roll-off that is inherent to most ribbon microphones, distant mic placement, or an overly "dry" acoustical environment.
