The AEA R84A and RPQ500 Package ties together two of AEA's fantastically complimentary offerings together in a great sounding, cost-saving bundle. This bundle includes a R84A, RPQ500 an Bento 2, a Front End Audio exclusive!

The AEA R84A / RPQ500 Package brings the tone-shaping flexibility of the RPQ500 to the home/project studio user. And since the A840 is such a versatile microphone enhanced by the sensitivity of it's superb on-board phantom-powered preamplifier designed by Fred Forssell, this bundle represents a total-package that is perfect for someone looking for one microphone that will work to record many different sources. It's particularly good for acoustic stringed instruments and vocals. This package contains what we like to call "gear for life" - you're getting a set of indispensable studio tools that you'll treasure for years to come.

AEA R84A Active Ribbon Microphone
The R84A was built on the success of the R84 and the legacy of the RCA designs. Incorporating the same Big Ribbon, modern JFET electronics, and high performance transformer as used in AEA's flagship active microphone, the A440, it is optimal for soft sound sources and classical recording. The A840 has an additional 12 dB of gain. The sensitivity with immunity to impedance

loading offers more flexibility in the choice of pre-amps, and eludes noise problems in low signal level applications.

AEA RPQ 500 Ribbon Mic Pre / EQ
The RPQ500 module, designed after the successful RPQ preamp, provides the same ultra-clean, high-gain signal path that has earned AEA preamps their great reputation, but in a 500 series package. JFET circuit topology provides all the dynamics, subwoofer bass, and fast transients that your microphones can record. The NoLoad input impedance above 10 kΩ means the RPQ won't load down a mic and change its sound. The RPQ's CurveShaper EQ gives you the tools to control your ribbons right at the start of the signal path. The Line/Mic switch bypasses the microphone gain stage and allows the EQ to be used for tracking with other preamps or during mixdown. Add the output level control, and the RPQ500 becomes a high-quality processing tool that can be used for mixing and mastering when combined with summing racks and mixers.

Fredenstein Bento 2 500-Series Power Supply Rack
The Fredenstein Bento 2 is a high performance two module carrier for API-500 compatible plug-in cards or Fredenstein Series 600 modules or API-500 compatible plug-in cards. The unit can accept a maximum of 2 modules. The Bento 2 features several important upgrades compared with third party products:

  • Universal power supply: Mains voltages range from 90V AC to 240V AC, 50 to 60 Hz.
  • Increased output currents: +/-16V DC 0.9A and +48V DC 0.033A
  • Additional I/O: TRS inputs and outputs, parallel to the XLR connectors.
  • Slot 1 can be daisy-chained to slot 2 by simply flipping a switch on the back-panel.
  • Compressor buss linking: Compressor modules can be linked by engaging a switch on the back-panel as well.
  • Secondary power-switch and voltage indicators are on the front-panel.

AEA R84A and RPQ500 Package Features

  • A complete turnkey solution for the incredible ribbon microphone sound that only AEA can deliver
  • An expandable 2 space 500-series PSU allows for you to start now with one mic and one module, and eventually add a second A840 and RPQ... or just mix it up. Whatever you want!

What We Think


The AEA R84A / RPQ500 Package from Front End Audio was created with the expressed purpose of maximizing one's sonic potential with the AEA ribbon microphone system. It's no secret that ribbon microphones sound great! But it's also no great secret that they sometimes have special care & feeding requirements when it comes to gain and impedance. So, the preamp relationship becomes paramount! But then AEA released a couple of wonderful Active Ribbon Microphones - the A440 and the R84A. The active electronics negate a lot of the problems that we experience when trying to match a passive ribbon mic with a mic preamp. However, the AEA RPQ proved itself to be a superior preamp even when paired with the active R84A and A440 microphones. With the release of the RPQ500, we had the idea to make a bundle which includes the 500-series power supply for free. Now with the emergence of the Fredenstein Bento 2, we've updated the bundle to include this power supply. The good news is that, not only is Fredenstein making a very reliable and well built set of tools, but the 2nd slot allows for this bundle to be expanded with the addition of another RPQ500 or any other 500-series module your heart desires. So, it's like slowly building your very own RPQ and your pace. Many of our customers have loved the option of purchasing this system at the savings that it offers. We invite you to discover the awesome power of a fully operational Ribbon Microphone System from AEA as assembled from us here at Front End Audio.
