AEA TRP The Ribbon Pre, Front

The AEA TRP is a high-input impedance two channel microphone pre-amp with fast response to both transients and overload recovery, specifically designed for ribbon microphones.


Simple to use, the AEA TRP pre-amp gives you Gain control, Level Control, HPF and phase reversal buttons for each channel. Phase reverse is particularly useful for setting your mikes up in a 'sum-and-difference', Mid & Side, pair, whilst the HPF allows you to govern the extent of the proximity effect when using close-miking applications.


By keeping the signal path to a minimum and using a specially designed JFET amplifier the AEA TRP can react quickly in the event of overload or in response to transients, as well as turning in ultra-low noise-floor figures for a clean, smooth response.


Audio Engineering Associates has done more to re-introduce classic ribbon microphone designs than almost anybody, for people who want the unique sound that their microphone range can bring - with the TRP, AEA provides you with the perfect preamp to complement them.
