Page 4: Introduction
INTRODUCTION The R44 is a passive, side address ribbon microphone with a bidirectional (or figure-of-8) pickup pattern. It was designed to be a part-for-part replica of the RCA R44 series, with the exception of using neodymium rather than alnico magnets. Everything else, including the 1.8 micron thick ribbon tuned to 16.5 Hz and the 1:28... -

However, passive ribbons such as the R44 can be damaged if ground (Pin 1) is accidently shorted, miswired, or hot patched in a patch bay to (Pin 2) or (Pin 3). Using phantom power with a faulty or miswired cable or a defective supply can severely stretch or break a ribbon. - Page 6 While the ribbon may not break, it nonetheless could significantly degrade the microphone’s performance. The ribbon in your R44 is protected from plosive and direct wind blasts by both the diamond-shaped grille and its acoustical fabric, as well as perforated metal and fabric blast screens internally on each side of the ribbon.
- Page 7 MICROPHONE POSITIONING Always use a sturdy microphone stand with the R44. Weighing in at over 8 pounds and more than 13 inches long, the R44 requires mounting on a strong, robust microphone stand with a heavy base or tripod. Large studio-booms with an appropriate counter-weight are recommended to prevent your R44 from tipping-over and crashing, causing injury to itself, a musician, or a valuable musical instrument.

We actively encourage users to visit access our comprehensive collection of in-depth articles and tutorials featuring the R44, along with a library of audio and video demonstrations of the R44 in action. If you are experiencing problems with your microphone, please visit the following troubleshooting section of our website: AEAribbonmics.com/support/troubleshooting-aea-products/... - Page 9 HOW TO MINIMIZE BLEED A significant and ever-present challenge in contemporary studio recording is minimizing leakage from nearby instruments into the various microphones. The deep nulls of ribbon microphones provide good rejection of unwanted sounds, which can be beneficial in sound reinforcement situations where feedback is always a threat.
- Page 10 R44 SERIES VARIANTS Our R44 Series microphones all share the authentic sound, feel and look of the original RCA 44. With careful technical modifications, we've created several varitions to accommodate modern applications and budgets.
