AEA TRP3 Ribbon Mic 2 Channel 1/2 Rack Preamp

Give your ribbon mics the power they deserve with the AEA TRP3 preamp. This 3rd generation circuit design provides two channels of high-output, high-impedance, and low-noise gain with a rich, natural sound that brings out the full potential of your microphones. Designed specifically for ribbon microphones, the TRP3 excels at drawing out the warm and lush sound that ribbons are uniquely known for. With 85db of output, the TRP3 gives you enough clean gain to record soft sources minus the noise typically associated with ribbon mics. With the TRP3, you will never consider a source too quiet to record with a ribbon mic again. This half-rack powerhouse provides unparalleled high gain and low noise thanks to AEA's clean musical circuit design.
