AEA TRP3 Two-Channel Half-Rack Mic Preamp
As the newest iteration of our classic TRP design, the TRP3 achieves unprecedented sound clarity with a combination of updated, modernized circuits and the tonal warmth so embedded in every AEA design.
While all AEA preamps share similar topology and sound, each unit differs in terms of features and form factor. The TRP3 packs a punch as a half-rack powerhouse, providing unmatched levels of clean gain and open, natural sound. Drawing on its predecessor, the TRP3 offers all the classic features of the TRP2 with the added benefit of more straightforward control markings and a responsive high-pass filter that, together, faithfully reproduce even the smallest details of microphones and other sound sources.
Equally well-equipped for ribbon, condenser and dynamic microphones, the dual-channel TRP3 delivers all the gain power of our RPQ3 in a more compact, half-rack package.
The TRP3 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 TRP3 can be easily racked with TRP3 Rack Ears. Rack two TRP3s side by side with a TRP3 Rack Shelf. These assemblies can be securely installed in any standard rack.
