Get all the clean gain you could ever need for the quietest mic sources with the AEA Ribbon Mics TRP3, a two-channel microphone preamp made in the USA by the same company known for its premium ribbon mics. This compact half-rack unit offers balanced XLR mic inputs and high-impedance, and low-noise circuitry, so it can yield optimal results with ribbon, condenser, or dynamic microphones.

Between the 12-position mic-pre gain and the continuously variable output level, up to 85 dB of JFET gain is available for each channel. Three LEDs are provided per channel for a clear indication of levels at -20, 0, and +24 dBu. Tame bass buildup and proximity effect at the push of a button with the low-cut filter, which cuts 3 dB at either 115 or 230 Hz, depending on your setting. The TRP3 includes an external universal switching power supply to allow operation in any country.

• Two channels with 85 dB of sweet and quiet JFET gain
• Switchable -3 dB low-cut filter at 115 or 230 dB
• Optimized for ribbon, condenser, and dynamic mics
• Switchable phantom power and polarity
• 68-kilohm high-impedance circuitry provides better transients, frequency response, and higher output sensitivity
• Switching power supply for use in any country
• 1 RU half-rack with optional hardware for mounting one or two units together
• Made in the USA

• LED Indicators: Green, yellow, and red LEDs indicate levels at -20, 0, and +24 dBu
• LF Switch: This inserts the 12 dB/octave low-cut filter at 100 Hz
• P48 Switch: Out is off; In applies full-spec P48 phantom power to the input (indicated by the red LED near the switch)
• Polarity Switch: Out is normal; In is inverted
• Mic Gain: This 12-position switch selects from +7 to +63 dB of preamplifier gain
• Output Level: This continuously variable control provides up to +22 dB additional output gain
