The AEA TRP3 Ribbon Preamp provides 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 TRP3 excels at drawing out the warmth and lush sound that ribbons are uniquely known for. Our 3rd generation circuitry is the cleanest and most musical design we've done yet.
