AEA TRP3 3rd Gen 2-Channel Microphone Preamplifier

With +85 dB of clean JFET gain, AEA's high-headroom, low-noise, handmade-in-California 2-channel preamp gets the most out of your ribbon mics (or any mics).

The 3rd-gen iteration of AEA's classic TRP design, the TRP3 achieves unprecedented sound clarity with a combination of updated, modernized circuits and the tonal warmth so embedded in every AEA design. While all AEA preamps share similar topology and sound, each unit differs in terms of features and form factor. The TRP3 packs a punch as a half-rack powerhouse, providing unmatched levels of clean gain and open, natural sound. Drawing on its predecessor, the TRP3 offers all the classic features of the TRP2 with the added benefit of more straightforward control markings and a responsive high-pass filter that, together, faithfully 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 of their RPQ3 in a more compact, half-rack package.


- Two-channel, high-gain, half-rack mic pre
- Ultra-high 68KOhm 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

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 read more sound that ribbons are uniquely known for. AEA's 3rd generation circuitry is the cleanest and most musical design they've done yet.

The TRP3 is a half-rack powerhouse that provides unparalleled high gain with low-noise. With 85db of output, the TRP3 gives you enough juice to record soft sources without ever having to worry about noise.

Passive ribbons and other low-level sources require preamps that supply a high level of output. Without enough clean gain, low-level mic signals can sound too soft or too noisy. This noise can be especially evident when recording quieter instruments (acoustic guitars, strings), recording at a distance or when using long cable runs.

With the TRP3, you will never consider a source too quiet to record with a ribbon mic ever again.

The worlds best microphones, coupled with AEA's range of transparent preamps, are the key choice for discerning recordists who want total control over their signal path

AEA offers the RPQ3, RPQ500, TRP3 and TRP500 microphone preamps, all of which provide clean gain and ultra high impedance to open up the sound of your microphones. All AEA Ribbon Preamps all share the same topology and sound. The differences between each unit come down to extra EQ features and form factor.
