Enhance Your Ribbons
The AEA 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.
A Gain Powerhouse
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.
High Impedance Makes a Huge Difference
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 TRP2 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 TRP2’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 TRP2’s impedance.
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.
Racking THE TRP2
The TRP2 is housed in a portable and lightweight half-rack aluminum chassis that allows you to easily take it to remote gigs, other studios, and on the road. AEA manufactures optional racking gear for convenient use in rackmount furniture.
A single TRP2 can be easily racked with TRP2 Rack Ears. Rack two TRP2s side by side with a TRP2 Rack Shelf. These assemblies can be securely installed in any standard rack.
