AEA RPQ - The Ribbon Pre
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.
Warranty Issue
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.
It has come to our attention that the original rack ears we manufactured for the RPQ do not work with some racks. If You encounter this problem we will ship new replacement rack ears at our expense. We sincerely apologize for any inconvenience this may have caused to you.
