Wheatstone NAB2017 Promo Images FM55e

NEW BERN, NC, USA (April 21, 2017) – Wheatstone introduced its second-generation FM-55 audio processor, the FM-55e, at this week’s NAB show.

The FM-55e includes all the same features that earned the FM-55 its reputation as the choice in value FM processing, but adds enhanced iAGC controls as well as an entirely new bass processing design.

“These enhancements give broadcasters that little extra competitive edge to what is still the best in its class, both from a sonic standpoint and the list of features” said Mike Erickson, Wheatstone Processing’s Systems and Support Engineer.  “The FM55e is another step forward in the creation of processing that is naturally loud, where stations that are on a budget can still sit at the grown up’s table.”

The FM-55e is a multi-band audio processor ideal for FM stations requiring sound consistency across a variety of source material. It includes the popular intelligent five-band AGC technology — or iAGC — coupled to a five-band limiter and stereo generator, plus five-band stereo enhancement and program adaptive L-R control for multipath mitigation.

Like the FM-55, the FM-55e fully supports the WheatNet-IP Intelligent Network, and is equipped with two analog composite outputs, two SCA inputs, balanced analog Left/Right outputs and an AES digital output that can be switched to deliver either discrete Left/Right or baseband192 digital multiplex signal.

“So many broadcasters have taken advantage of the baseband192 digital multiplex signal in the FM55 and now the FM55e” said Erickson.  “Like all Wheatstone processors, the FM55e runs at a sample rate of 192kHz, so adding this extra feature early on was easy for us and allows for extra connectivity options for our customers. 

The FM-55e comes in a 1RU package with front panel OLED display and GUI navigation. 

Existing FM-55 owners will be able to update their current unit with new FM-55e software free of charge when it is released later this year.  “The update from FM-55 to FM-55e is a free software update” said Erickson. 

The FM-55e was introduced at NAB, booth N6531.
