AIRAURA X1

Golden ears sound at a midrange price.

Proven technology for FM and HD processing at very friendly price 
AND control points.

Making serious inroads into midrange priced on-air audio processing, the AirAuraX1 uses all the advanced algorithms found in Wheatstone’s top-of-the-line AirAuraX3 for turning up the volume without causing listener fatigue, yet comes with a user interface that doesn’t require a power user to operate.

“We designed in all the incredible power tools that made the AirAura X3 a popular choice in the top markets, and then equipped the X1 with newly designed GUI and front panel user interfaces. This presents audio controls to the user in a clear and intuitive way that is perfect for mid- to small-market broadcasters,” says Jeff Keith, Senior Product Development Engineer for Wheatstone’s Vorsis audio processing line.

The new AirAura X1 is the first processor in the midrange price category granting access to advanced processing features via an easy-to-use interface. Intuitive adjustments made via the front panel touchscreen interface result in automatic and intelligent adjustments of behind-the-scenes processing parameters to create the sound the user desires. 

A library of expertly created factory presets always keeps users in safe territory, while an advanced professional GUI allows experienced “golden ears” to delve deeper to refine the sound.Bring new features and new technology into a mid-priced audio processor for FM and HD stations while keeping the price just right. And with that, Wheatstone proudly presents the AirAura X1.

AirAuraX1: 5-Band Spectral Controller

Competitive audio in any market requires the use of multiband. Since the dawn of the multiband AGC/Compressor, the goal has been to improve tonal consistency and increase loudness by making algorithms smarter and, in turn, making the effects of multiband control less audible. We have something very new and very exciting in X1 that takes that control to a new level.

Most processors have AGC or Compression or maybe both. At any given time, these algorithms are working based on user settings, regardless of the type of audio being fed to them. We sat and thought about that for a bit. We also have AGC and Compression in our 5 band processing and it’s really a good performer. But how can it be better?

The iAGC in the FM55 and AirAura X3 is a very smart algorithm and we collect a lot of data from it. We can slow down and speed up the processing based on dynamic range and amplitude. But what if we could also use that data in our 5 band AGC/Compressor to make IT even smarter?

Introducing our 5 Band Spectral Controller. Calling it an AGC or Compressor is not really valid anymore because it’s both… or one or the other… or sometimes neither. In our effort to minimize processing artifacts wherever and whenever possible, the development of the 5 band Spectral Controller allows us to use the iAGC technology built into X1 to map not just amplitude and dynamic range, but also to chart spectral history. This data can be used to dynamically adjust our 5 band spectral controller to yield unprecedented tonal balance cut to cut WITHOUT the audio sounding over-equalized, artificial or “boxed in” to a signature.

Of course, if consistency to the SOURCE is what you are after, that can easily be attained as well. What’s the purpose of having your cake if you can’t eat it?

AirAuraX1: 10-band Mastering Limiter

New challenges bring new ideas. It’s behind everything we do at Wheatstone, and processing is no exception. You’ve read about how we customize audio for consistent level and tonal balance, now it’s time to really get serious. Peak management that doesn’t distract from the sound you’re after.

Introducing another first in a Wheatstone audio processor – the 10 Band Mastering Limiter. There’s one for FM and one for HD.

It starts with something that sounds pretty simple: a 10 band limiter. What’s so special about that? When the limiter works in conjunction with the data pulled from the iAGC and 5 band spectral controller, things start to sound more interesting. When we tell you that the 10 band limiter makes on-the-fly decisions from the real world data we have collected to maximize clarity, things become exciting. And when we tell you the audio from each band of the 5 band Spectral Controller is managed by not ONE but TWO limiter bands to allow for more precision, the choice is obvious. 

AirAuraX1: Intelligent Audio Management

The AGC (Automatic Gain Control) in a modern broadcast facility works harder than ever before. More and more often, studios are unmanned and the levels on your console become set it and forget it. If your sources aren’t carefully controlled it’s up to the AGC to make those corrections. But even then a competent AGC is not enough. Differences in amplitude AND dynamic range must be considered for an AGC to properly operate in “the zone”. That’s where iAGC comes in. Not just a leveler, the iAGC is an amplitude AND dynamics manager that helps ensure the right amount of processing is added to your source material.

Is it too dense? The iAGC relaxes the processing so that dense material doesn’t sound “double processed”. Does your audio need more punch? If there is a lot of dynamic range in your audio, you can choose to leave it alone, or let the iAGC make real time adjustments to “program match” your audio to yield a consistent audio signature.

The choice is ultimately yours, but the possibilities are endless!

AirAuraX1: BS412 Multiplex Loudness Manager

Our new Multiplex Power Wizard utilizes a program-dependent prediction, detection, and measurement algorithm that continuously adapts the controller’s behavior to the incoming program content. The algorithm allows for the extremely tight multiplex power control desired by many European broadcasters, but without contributing noticeable or undesirable control-related audio artifacts.

AirAuraX1: Matching the Medium

The HD and FM side of your audio processor require much different approaches for peak control and bass management. What sounds good on FM may be too much for the HD component. You want to emulate your FM signature on HD, but also make it stand out on its own. When the receiver blends to HD, the sound should have more detail and should be engaging to listen to but not SO different that it becomes distracting.

With X1, you have the tools to create on your audio canvas on both the FM side and the HD. There’s no real worry that adjustments made to the 5 Band Spectral Controller will improve one path and degrade the other. With our separate 10 Band Mastering Limiters, the right amount of virtually everything is applied, matching your signature sound to the medium.

AirAuraX1: Insert Point

Essential to the livelihood of most major market stations is the ratings watermark. We will admit that there is a lot of information available out there on how to deploy and use these watermark encoders. We’re just here to say we give you an extra option; the option to insert your watermark encoder towards the back of the processor, where it just may be a bit easier to detect by the meter. It also doesn’t hurt to place the watermark encoder AFTER processing stages that have maximized your source material so that it’s as consistent as can be, yielding even more opportunities for the watermark encoder to embed its signals.

AirAuraX1: Perfectly Aligned

With our partners at Belar and DaySequerra, you can now guarantee that your HD and FM audio is perfectly time aligned. With either the Belar FMHD-1 modulation monitor or the DaySequerra Series 2 M4 Time Loc, you can continuously measure your FM/HD time alignment and transmit closed-loop diversity delay corrections back to the Wheatstone on-air processor via our ACI interface.


Wheatstone® Baseband192

Wheatstone’s baseband192 is an open standard technology that eliminates the use of an analog composite interface between processing and transmission, which has been the last holdout to the 100% digital air chain. A single AES/EBU cable between a Wheatstone processor and a current solid-state FM transmitter carries the baseband signal, bypassing the need 
for multiplexing in the exciter and eliminating the resulting signal overshoot with associated loudness tradeoff. The baseband192 interface is now available as a standard feature in Wheatstone AirAura X3, AirAura X1, FM-55(e), FM-55, FM-25 and Aura8-IP audio processors.
