Ribbon Mic Pre with Phantom Power and Curve Shaping, Two Channel

RPQ

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 80dB of clean and quiet gain, with extended bandwidth from below 1Hz to beyond 200kHz, 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 mast 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 compensates for the high-frequency roll-off that is inherent to most ribbon microphones, distant mic placement, or an overly "dry" acoustical environment.
