AEA TRP2 Ribbon Microphone Preamplifier
The AEA TRP2 preamp provides two channels of high-output, high-impedance, and low-noise gain in a half-rack package with a rich and natural sound that brings out the full potential of your microphones.
- Two channels with 85dB of sweet and quiet JFET gain
- Switchable phantom-power, polarity reverse, and high-pass filter
- 63k ohm high-impedance circuitry providing better overall transients, frequency response, and higher output sensitivity
- Optimized for ribbon mics, condensers, and dynamics
- Switching power supply for easy use in any country
- 1U half-rack with optional hardware for mounting one or two units together
- Made in the U.S.A.
Professional Features in a Compact Package - The TRP2 is AEA’s second iteration of the high-performance TRP preamp with the addition of new features including phantom power, optional rack ears, and a switching power supply. Polarity reverse switches for ensuring proper polarity throughout the recording chain and switchable 100 Hz, 12 dB per octave low-frequency filters allow you to tame proximity problems. The TRP2 includes switchable phantom power that is capable of powering condensers and active ribbons. For engineers concerned about phantom power hurting their passive ribbons, there is phantom power kill switch, known as No Blow Mode, located internally within the unit that easily deactivates 48V from ever turning on.
A UNIVERSAL POWER SUPPLY - An external switching power supply with a grounded AC plug is used with the TRP2 so hum fields can be kept away from the high-gain electronics. The power supply allows the TRP2 to be used in any country without any modifications made to the unit.
