In 1998, AEA released its first museum-quality reproduction of the
iconic RCA 44. Now, in 2023, we honor our continued legacy with a
limited edition homage to the RCA 44BX: the 44-CX 25LE. Complete
with a three-position inductor high-pass filter switch and original
color-matched transformer case, this unique product recalls the
vintage sound of the 44BX with the added benefit of modern
components and materials.
Vintage aesthetic, vintage sound
Much like the original 44BX, the 44-CX 25LE features an umber gray
case and brushed satin plated finish, custom “meatball” logo badge
in original RCA font, and brown cabling. Look closely, and you might
even spot a color difference in the grille silk, which is slightly more
muted to emulate an aged mic.
The most exciting feature of the 25LE is the three-position circuit
jumper switch at its base. Historically, many broadcasters and
musicians alike modded their BXs with similar switches, eliminating
the need to open the case for adjustments.
Inspired by old RCA schematics of the 44BX’s “reactor” (now
commonly referred to as an inductor), our team collaborated closely
with Cinemag Transformers to develop the best-sounding inductor-
transformer combination. The 25LE model features a 1:32 transformer
(rather than our standard 1:28), paired with an inductor that is
connected to the secondary of the transformer in various
configurations. By switching the toggle on the bottom of the 25LE,
you can choose between:
– “M” (or “music,” which bypasses the inductor)
– “V1” (a slight high-pass filter, best for taming more distant or mid
range vocals)
– “V2” (a more aggressive high-pass filter, for close miking, deeper
vocals, or just sound coloration)
FEATURES of the 44-CX 25LE:
• Museum-quality homage to the RCA 44BX
• Bronze investment-cast yoke, finished in satin nickel
• Three-position toggle switch selects between “Music” (no filter/
classic 44 sound), “V1” (HPF), and “V2” (more aggressive HPF)
• Custom 1:32 transformer (original AEA R44CX is 1:28)
• Full and rich sound; smooth highs and warm lows, with additional
signal coloring options
• Vintage-inspired look with classic brown XLR cable and non-
reflective, umber transformer case
