RPQ3
Microphone Preamplifier
From AEA:
The AEA RPQ3 preamp and EQ utilizes our newest 3rd generation circuit design. Two channels of high-output, high-impedance, and low-noise gain with our unique EQ architecture optimizes the performance of your microphones.
Specifically designed for ribbon microphones, the RPQ3 excels at drawing out the warmth and lush sound that ribbons are uniquely known for.
The RPQ3 is a powerhouse that provides unparalleled high gain with low-noise. With 85db of JFET output, the RPQ3 gives you enough juice to record soft sources without ever having to worry about noise.
