    The AEA TRP 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 metering.
