Wheatstone was the first to develop an intelligent, “program density aware” AGC (2007 - Sweet Spot Technology, or SST). We were also the first to employ the science of human psychoacoustics in the design of a multiband limiter (2005, our acclaimed 31‑band limiter).

    “sought after” sound no matter what the market size. Like other Wheatstone processors, the AM-55 has been carefully designed to not have a fixed sound of its own – the end user can use the AM-55’s vast pallet of tools to create any desired on-air sound.

    AM‑55 and devices imm ediately above and/or below it. WARNING! With very few exceptions, the AM-55 chassis DOES NOT need to be opened in the field. Please be advised that the AM‑55 contains high voltage power supply circuits operating at voltages well above AC line input.
  • Page 12: Am-55 Installation Tips

    Use ground conductors with the largest possible surface area and keep ground leads as short as possible. The AM-55’s ground reference is its chassis, which should be connected to the station ground. Such a connection is especially important when the AM-55 is operated in a high RF environment because it helps minimize differential voltages between the processor’s chassis and other pieces...

    The AM‑55 GUI allows you to adjust the processor and see, in real time, how it is reacting to the audio being processed. All Wheatstone GUI’s have been carefully designed so that no adjustment is more than two mouse clicks away.

    The GUI may be positioned on the host computer’s screen by left‑clicking and holding the “Wheatstone” logo and dragging the GUI to the desired position. In normal “Windows” fashion, the GUI may be minimized on the desktop (taken off the screen) and/or closed by way of the familiar controls at the extreme top right.

  • Page 62: Hf Correction

    When bandwidth restrictions cause modulation overshoot, the best way to minimize it is to (1) reduce the bandwidth of the signal entering the transmission system, (2) reduce the rise time of the waveforms exiting the audio processor, or (3) a combination of both. page 3 – 31 AM-55 / Sep 2015...
