Know before you buy
While the TRP3 is specifically engineered to bring out the best in ribbon microphones, it is a versatile preamp that works exceptionally well with condenser and dynamic microphones, too.
Ribbon microphones often have low output levels, requiring significant gain to reach a usable signal. With 85 dB of clean gain, the TRP3 allows you to capture quiet sources—like acoustic instruments or distant room sounds—without introducing audible noise or hiss.
The TRP3 features a dual-option high-pass filter at 115 Hz or 230 Hz, which is useful for cleaning up the 'muddy' low-end buildup that occurs when a microphone is placed very close to a source.
Yes, the TRP3 is a two-channel unit, making it an excellent choice for stereo miking techniques like Blumlein or Mid-Side, or for recording two separate mono sources simultaneously.
Yes, by moving the power supply outside of the chassis, AEA minimizes the risk of electromagnetic interference and hum, ensuring a cleaner signal path and a lower noise floor.
High input impedance prevents the preamp from 'loading down' the microphone, which allows the mic to operate at its full potential and ensures a more natural, open frequency response.
