When looking for quality – meaning great performance and durability – in aviation microphones, it may be better to look at longevity of products than at what's new.
Take the 57 Series of microphones (pictured at right) from Holmberg, for instance. Known as "The Legend", it has been in production since 1957 and can be found on early Airbus and on DC-9's and D-10's and a wide variety of other aircraft. It's available in several versions, from standard (40mV/Pa) to high (120mV/Pa) sensitivity and with different plugs. (PNR 85-13-X-01 and -02).
So is there anything new? An event: Holmberg is now the supplier of the standard cockpit microphone for the A320 family of Airbus aircraft (pictured at right). PNR 85-16-11494-05 is a noise-canceling electret microphone that fits existing cradles and connectors in the single-aisle Airbus cockpit. It has a metal body for added durability, standard sensitivity (40mV/Pa) and comes with circuitry to counter 400 Hz noise problems.
Erie Aviation, Inc. is pleased to offer these microphones, and also complete repair services, including warranty, for these and other Holmberg products. Please give us a call at 1-814-838-8934 or send us an e-mail if you have questions.
