The R84A: An Active Version For those who cannot always have the right preamp available, AEA offers the Active R84A (formerly known as the A840), a premium version of the R84 complete with JFET electronics and the same custom transformer used in our active R44. It’s basically an R84 with a built-in preamp.
The extra 12db of output is a huge help when recording quiet sources like vocals and soft acoustic guitars. The active circuitry also prevents noise, interference on long cable runs or when operating near large lighting rigs. The R84A requires standard 48-volt phantom power to operate the active circuitry. The R84A also possesses an 18-carrot, gold-plated grill.
