AEA TRP – The Ribbon Pre Description
The
AEA Ribbon Mic Preamplifier is an ultra high-gain and impedance, minimal-path
FET mic pre designed by Fred Forssell. This low-noise two-channel preamp is for
ribbon, moving coil, and tube microphones that do not use or want phantom
power. This allows for improvements in minimal path circuitry and also rids the
unit of phantom-power blocking capacitors. Zener diodes on the input protect
the input stage if external phantom power is applied.
First stage gain is set from +6 to +63 dB by a 12 position Grayhill switch.
Another 20dB of gain is available after the output level potentiometer.
Polarity reversal and high pass switches on the two channels are complimented
by operating and overload LED meterin

AEA TRP “The Ribbon Preamp” Review /
See
All ZenPro Audio Reviews Here: Review Page
This was the first time I ever
plugged my AEA R84 into a pre and realized that no matter how quiet the source
I was trying to record was, there is ALWAYS gain left over. The TRP is a
seriously cool half rack preamp, aimed squarely at ribbon mic use with its 18k
ohm input impedence and +83dB of quiet and clean gain. There is no phantom
power on board, so all the worry-warts out there who think they are going to
pop their ribbon elements with phantom power need not worry.
You can use the TRP with tube mics
(since they have their own power supply) and dynamic moving coil mics as well.
For a clean and clear, detailed and low noise preamp you just can’t go wrong. Mainly
I would suggest the TRP for ribbon mic owners who really really really want to
hear the MIC and not a bunch of noise brought up by cranking their preamp. You
will hear your ribbon mics in all their glory, trust me.
Conclusion: Another Fred Forsell
designed preamp from AEA, specifically tailored for ribbon mic use and an
absolute winner.
