WELCOME

Congratulations on your purchase of the TRP2 preamp and welcome 

to the AEA family. AEA takes sonic integrity seriously and have created 

preamps that have been specially designed to meet the particular 

challenges of ribbon mics and to bring out their full potential. Building 

on the obstacles identified when designing preamps in the 50’s, 

we now use tools like quiet JFETs and transformer-less designs to 

construct clean, high gain, high impedance preamps. A passive ribbon 

mic is only as good as the preamp you match it with. Whether you are 

using an AEA ribbon or any other passive ribbon mic, we understand 

how much you can enhance the sound of your ribbons with the right 

preamp. The TRP2 is the perfect companion for any and all ribbons, 

condensers, and moving-coil microphones – whenever a true and 

pristine signal path is desired.

Your TRP2 is 100% handcrafted in Pasadena, CA. AEA is a family owned 

company with a small crew of skilled technicians – most of them being 

musicians themselves. Proudly independent, we still manufacture all 

our ribbon microphones and preamps by hand from locally sourced 

parts.

We hope that the TRP2 will help you capture many magical 

performances that touch the heart. Please read this manual thoroughly 

to make sure that you get the best sound and longevity from your 

new preamp. We invite you to become part of the AEA community by 

sharing your experiences with the TRP2 via e-mail, phone or our social 

media.
