Wheatstone AIR AURA X5 FM & HD Audio Processor
Meet X5, Wheatstone’s new flagship FM and HD audio processor.
Built from the ground up, it's based on several breakthroughs, including an innovative new approach to dynamics control and pre-emphasis management.
In more traditional audio processing designs, pre-emphasis is either managed by specialized limiting or carefully designed clipping that merely tolerated the pre-emphasis curve. Thinking about this problem, and the fact that it’s been over a decade since there has been a major development about dealing with pre-emphasis, Wheatstone set out, through our work with DSP, to come up with the ultimate solution to the problem.
We have seen what the power of DSP can do to restore audio and video over the years. What if we found a way to apply that thinking to FM pre-emphasis and peak control?
Enter LIMITLESS. FM peak control technology that reconstructs the audio after the application of pre-emphasis. No more dull smeary highs or spitty audio. Just clean and clear high end that’s perfectly matched to the texture of your HD audio.
X5 also leads the way with Unified Processing®, which allows the processor to share information between ALL stages. In the X5, the iAGC, Dynamics and Limitless Clipper work together no matter which control a user adjusts. Changes are made automatically, in real time, in ways never envisioned before.
The X5 also includes a totally redesigned limiter. As part of the Unified Processing system, this unique limiter, designed as 31 independent filter banks with no crossovers to colorize the audio, works directly with the X5's Limitless clipper, providing an audio blueprint for how the clipper should behave.
Additionally, X5 offers a full suite of static and dynamic RDS features along with with multi-stream UECP support.
The X5 adds a number of other state of the art features, including LIVE LOGGER which documents everything from remote logins to audio failover to preset changes. Our redesigned bass processor and enhancement controls in the iAGC that allow you to safely equalize your audio for maximum consistency. The days of “maybe it will sound better on the next song” are over. Your audio signature is preserved cut after cut, element after element.
Wheatstone’s popular HD/FM audio alignment makes the jump to the X5 with our FM&HD LIVELOCK. The system works either with third-party HD/FM modulation monitors or by itself, using the FM/HD tuner built in to the X5.
Additionally, you can now keep the processor at the studio and still keep HD and FM audio in perfect alignment to the transmitter with our optional MPX SYNC-LINK receiver. MPX SYNC-LINK manages multiple audio streams to keep them in perfect sync, preventing any possibility of the FM and HD audio getting out of alignment.
AES insert points are also available via PPMport. Users can now insert their ratings encoder into the processing system instead of placing it in front of the processor. This allows the X5’s specialized front end to deliver a steady audio diet to the encoder and increase the instances of watermark embedding. What’s more, the sonic transparency of the LIMITLESS clipper preserves the watermark for more reliable detection at the meter.
X5 also offers built-in watermark encoding for the Kantar Media ratings measurement system.
We’ve spoken a lot about what’s new in X5, but Wheatstone processing users will be happy to know that many of the features we’ve pioneered in previous models have been incorporated and improved on in the X5, including our legendary Multipath Mitigation algorithm, our composite processing system with selectable look ahead limiting or clipping, baseband192 composite AES connectivity, and a full set of analysis displays.
