The TRP2 Ribbon Preamp provides two channels of high-output, high-impedance, and low-noise gain with a rich and natural sound that brings out the full potential of your microphones

Specifically designed for ribbon microphones, the TRP2 excels at drawing out the warmth and lush sound that ribbons are uniquely known for.

The TRP2 is a powerhouse that provides unparalleled high gain with low-noise. With 85db of JFET output, the TRP2 gives you enough juice to record soft sources without ever having to worry about noise. With the TRP2, you will never consider a source too quiet to record with a ribbon mic ever again. Passive ribbons with low output levels require preamps that supply a high level of output. If the preamp you use doesn't have enough clean gain, the mic signal may seem too soft or noisy which may be apparent when recording quiet acoustic guitars or strings, especially at a distance or with long cable runs. The TRP2 eliminates this concern.

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.

The sound and tonality of dynamic microphones like ribbons and moving-coils are directly affected by the impedance of a preamp. The higher the impedance, the better the sound. The RPQ2 boasts an extra high input impedance of 63K Ohms. Preamps with an impedance of under 10k ohms will limit the lows, highs, and transients of your passive microphones. The RPQ2's high impedance will reveal your microphone's true nature- a thick low-end, open top-end, and articulate transient response that you will need to hear to believe. Both condensers and active microphones will also benefit from the RPQ2's impedance.

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.

The TRP2 is housed in a portable and lightweight half-rack aluminum chassis. This form factor allows you to easily take it to remote gigs, other studios, and on the road. The TRP2 can be easily racked with the optional TRP2 Rack Ears. Attach the rack ears to the TRP2 and unit can be securely installed in any standard rack. Two TRP2s can be mounted side by side in a single rack space by purchasing the AEA TRP2 Rack Shelf. Screwing two TRP2s to the rack shelf, the whole assembly can be securely installed in any standard rack.

Input impedance: 63K Ohms (10K Ohms when P48 is engaged)
Input Gain control:
Twelve-position switch provides from +7dB to +63dB of gain for the preamplifier circuit, as measured between the input and the before the output line driver.
Switched LF Shelving filter: 12dB per octave from 100 Hz
Color LEDs: Yellow, Green, Red
XLR output maximum level into 600 load: +28 dBu, balanced; 0 dBu = 0.7746 V rms
XLR connectors polarity: Pin-1 is ground, pin-2 is high, pin-3 is low
LED signal level indicators:
The green LED snaps on at -20 dBu to indicate the presence of signal; the yellow LED snaps on at 0 dBu; the red LED snaps on at +24 dBu to warn of approaching signal overload.

External Features:
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. The power supply uses a 5-pin XLR connector for its output. It has one 18 volt AC secondary winding, which is used within the TRP2 to provide three regulated DC voltages. Bi-polar 18-volt rails are provided for the electronics and a +12 volt rail for the Aeromat relays.
