INTRODUCTION

The TRP3 is a half-rack, two-channel, high gain and high impedance 

microphone preamp. Specifically designed for ribbon 

microphones, the TRP3 (The Ribbon Preamp) excels at drawing out 

the warmth and lush sound ribbons are uniquely known for. 

However, when a preamp works well with a passive ribbon 

microphone, it will excel on every microphone. With 85

 

dB of sweet 

JFET gain, the TRP3 delivers the quietness and headroom needed 

for today’s high-resolution recordings. The TRP3 is a cost-effective, 

high-quality solution providing a pure and transparent signal path 

for all ribbons, condensers, and moving coil microphones. The 

TRP3’s combination of ultra-low noise, low-distortion op-amps, 

ultra-high 68

 

kΩ input impedance, and 85

 

dB of clean gain 

provides all the dynamics, subwoofer bass, and fast transients that 

your microphones can deliver. As with all AEA electronics, the 

circuit in the TRP3 was designed by Fred Forssell.
