A compact, half-rack package.

The TRP3 from AEA achieves unprecedented sound clarity with a combination of updated, modernized circuits and a tonal warmth embedded in every design.

The TPR3 may be a half rack, but it packs powerful punch that provides unmatched levels of clean gain and open, natural sound. The TRP3 offers all the classic features of its predecessor with more straightforward control markings and a responsive high-pass filter that reproduce even the smallest details of microphones and other sound sources.

Equally well-equipped for ribbon, condenser and dynamic microphones, the dual-channel TRP3 delivers all the gain power with a compact half-rack package.


  • Two-channel, high-gain, half-rack mic preamp
  • Ultra-high 68KΩ input impedance (phantom power off)
  • 7 to 85 dB of gain
  • 48V phantom and polarity switch
  • HPF switchable -3dB at 115 Hz or 230 Hz
  • External PSU
  • Optional rack ears (for one unit) or rack shelf (two units) for mounting purposes
