Preamp designed for ribbon mice.

Most preamps are geared towards the needs of condenser mics. But if you’re miking with a ribbon, you’re probably doing it because you want to hear the smooth, open tone that a ribbon gives you. However, if you’re using a mic pre designed for condensers, you might be trying to fit a ribbon-shaped sound through a condenser-shaped hole, and throwing away much of the ribbon’s tone in the process. In fact, you may have never heard everything your ribbon mics are capable of.

The AEA TRP is the first mic preamp designed specifically to fit the needs of a ribbon mic. First, the JFET discrete front end provides 83dB of gain. AEA made that gain as quiet as physically possible by leaving out the phantom power circuitry and giving it an external power supply. The TRP’s 300 kHz of bandwidth makes it well-equipped to handle fast transients and the Low-Energy-Storage (LES)TM circuit topology allows it to recover instantly from overloads, providing you with everything you need for 192 kHz high-resolution recordings.

The AEA TRP is optimized for ribbon, moving coil, and tube mics that don’t need phantom power. It allows you to hear more of what you want to hear and less of absolutely everything else.
