AM-55

You won’t believe how great AM can sound...

Our AM-55 AM audio processor is powerfully modern, yet affordable. 

AM55 FrontPanel 100115

The AM-55 stands out from all other AM processors due to its intelligent five-band AGC technology — or iAGC — coupled to a five-band limiter. The combination provides automatic and superior real-time program density control for a consistent, spectrally-balanced sound regardless of density variations in incoming source material. Other features of the AM-55 include effective bass management, IP network interface and a powerful GUI interface.

The AM-55 accepts analog and digital sources, and automatically switches sources upon loss of the primary signal. A phase rotator assures that voice is as loud and clean as possible when processed. 

This processor interfaces to the WheatNet-IP Intelligent Network, making it possible for broadcasters to stream its audio to and from anywhere in the IP audio network. Like its cousin the FM-55 audio processor, the AM-55 is smartly designed with a front panel OLED display, Guru GUI navigation and headphone jack — as well as the incredible sound and build quality that the industry has come to expect of a Wheatstone audio processor.

Intelligent iAGC
A Wheatstone exclusive, our newly developed adaptive multiband iAGC — or intelligent AGC — allows unobtrusive transitions between hyper-compressed recordings and those with more dynamic range. Our iAGC effectively manages the behavior of the multiband AGC as program content density changes, something a typical broadband AGC simply cannot do.

Crossover frequencies are adjusted so that even at the most narrow transmission bandwidth settings, you still have five full bands of AGC in order to assure good intelligibility on AM radios.

AM Bass Management System
Processing bass for AM has always been a challenge. The goal, rarely achieved, is to produce a strong punchy bass without distortion or strange dynamic gain changes. The AM-55’s Bass Management System is optimized for AM and circumvents lower-end related distortion plaguing other broadcast audio processors. It works in concert with the limiter to proudce a natural, well-controlled bass sound.

WheatNet-IP Compatible
WheatNet-IP I/O compatibility makes it possible to control the FM-55 and stream its audio to and from anywhere in the IP audio network, making it 100% compatible with WheatNet-IP surfaces and controllers!

Audio Processing Guru® Software 
Processing is as much art as science. If you’re more artist than scientist and have trouble keeping track of the dozens and sometimes hundreds of controls that modern processors offer, Audio Processing Guru® software will be the key to happiness. It condenses the functions of the various processor controls down to just a few, easy-to-understand sliders, enabling you to concentrate on what you hear, not what you see. It’s as if we sent a processing expert with each box! GUI Guru makes the tough, behind-the-scenes decisions based on the simple-to-use controls supplied for texture (Drive, Density, Loudness) and EQ (Low, Warmth, High).

WheatNet-IP Extends AM-55's Power

With WheatNet-IP BLADE-3s, you get a virtual rack room in a 1-rack space box. They handle all the I/O (AES/EBU, SPDIF, AOIP, MADI, SDI and AES 67) and provide full routing capabilities. Each BLADE-3 gives you two 8x2 utility mixers, 12 universal GPI/O ports, 128 software logic ports, silence detection, built-in audio clip player, stereo multi-band audio processing, and much more, assignable anywhere on the network. With it you can create workflows that would require a ton of third-party gear.
