This cool cat has big processing chops and a small footprint. Get more roar without taking a big bite out of your wallet. Our LiON has the latest Wheatstone DSP algorithms; it is not a 90’s era processor by any means. The AUDIOARTS LION Five-Band Processor/Multipath Controller has WheatNet-IP, so it can be networked. It has analog and AES3 so it can stand alone. It has Wheatstone SystemLink™ built in, to send full 24-bit linear audio directly to your transmitter over reliable high-speed links — Baseband 192 MPX with FM+HD timing locked (no codec to degrade audio quality). And it comes with 50 presets so you can plug and play. 

WHEATSTONE INTRODUCES THE AUDIOARTS LION
(FM/HD AUDIO PROCESSOR)

At last, an affordable FM/HD audio processor with the algorithm prowess for transforming highly compressed source music into a more robust, dynamic listener experience on any device, anywhere.  

Wheatstone’s mighty LiON, a new FM/HD audio processor with the algorithm prowess to deliver the best on-air quality, even from highly compressed source material.

To deliver airy highs, a smooth midrange, and deep lows you can feel, this low-cost, half rack sized FM/HD audio processor uses Wheatstone’s advanced next-gen multiband AGC and clipping algorithms developed specifically for today’s source content and listening devices.

The Audioarts LiON includes stereo enhance, RDS, and Wheatstone SystemLink™ for transporting the entire MPX and HD audio signals, including RDS, maintaining perfect FM/HD alignment across any high-speed data link. Available in double or single rackmount options.

Let Your SignalRoar on a kitten budget

Unique to Wheatstone processors, the LiON includes our intelligent five-band AGC technology — or iAGC — coupled to a five-band limiter and stereo generator. 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.

LiON is part of the WheatNet-IP audio network, with a full-blown interface, so you can set up and trigger presets remotely now and add on to your WheatNet-IP ecosystem later. It also includes 192kHz digital MPX connectivity to the transmitter for end-to-end native IP audio quality. It is equipped with two analog composite outputs, two SCA inputs, balanced analog Left/Right outputs and an AES digital output which may be switched to deliver either discrete Left/Right or baseband192 digital multiplex signal. Input audio may be delivered via analog, AES or WheatNet-IP.

For local and/or remote control, there's a full graphic user interface that allows you to tailor every function of the LiON, so tweaking and making changes is both intuitive and accessible.

Intelligent iAGC

Our adaptive iAGC – or intelligent AGC – allows unobtrusive transitions between hyper-compressed recordings and those with more dynamic range. Effectively manages the behavior of the multiband AGC as program content density changes, something a typical broadband AGC simply cannot do. By coupling the iAGC and mulitband AGC, we are able to produce a consistent, spectrally-balanced sound regardless of density variations in incoming source material.

Smart Stereo Enhancement

The LiON’s Smart Stereo Enhancement provides a wide but extremely stable ‘on-air’ stereo image. “Wide”, “alive”, “exciting to listen to”, and “very natural sounding” are terms customers have used to describe how our stereo enhancement method sounds. Users have reported hearing artistically important nuances in music that were simply inaudible when processed by competing products.

Bass Tools

The LiON Bass Management System circumvents bass-related distortion plaguing other broadcast audio processors. The result is increased depth, feel, and clarity of bass impact without affecting mid and high-frequency program – in fact, the clarity of higher-frequency audio is actually enhanced by the new algorithm.

Multipath Mitigation

Manipulating the stereo field intelligently can dynamically (on a song-by-song basis) mitigate problems created by multipath for FM stereo stations and help them achieve maximum audience reach.

MPX SystemLink Wheatstone Baseband 192

Wheatstone® baseband192 digitizes the entire multiplex spectrum including RDS and SCAs up to 80kHz, providing a higher performance interface than using the classic analog composite method between processing and transmitter. A single AES/EBU cable between the processor and a current solid-state FM transmitter carries the digital baseband signal, bypassing the need for multiplexing in the exciter and eliminating the resulting signal overshoot with its associated loudness tradeoff. 


Features   
  • Intelligent iAGC - allows unobtrusive transitions between hyper-compressed recordings and those with more dynamic range. Effectively manages the behavior of the multiband AGC as program content density changes, something a typical broadband AGC simply cannot do. By coupling the iAGC and mulitband AGC, we are able to produce a consistent, spectrally-balanced sound regardless of density variations in incoming source material.

  • Clipper - distortion-masked FM peak clipper

  • Bass tools - The LiON Bass Management System circumvents bass-related distortion plaguing other broadcast audio processors. The result is increased depth, feel, and clarity of bass impact without affecting mid and high frequency program – in fact bass detail and the clarity of higher frequency audio are actually enhanced by the new algorithm. 

  • Wheatstone Unified Processing - means each stage in the processing chain intelligently interacts with the other processing stages to create a dynamic and dominant on the dial presence.

  • Multipath Mitigation - Manipulating the stereo field intelligently can dynamically (on a song-by-song basis) mitigate problems created by multipath for FM stereo stations and help them achieve maximum audience reach

  • Smart Stereo Enhancement - The LiON’s Smart Stereo Enhancement provides a wide but extremely stable ‘on-air’ stereo image. “Wide”, “alive”, “exciting to listen to”, and “very natural sounding” are terms customers have used to describe how our stereo enhancement method sounds. Users have reported hearing artistically important nuances in music that were simply inaudible when the same material was processed by competing products. Four band parametric EQ lets you tune in your signature sound.

  • RDS generator - Full FM RDS capability so that the encoder you were going to have to buy to generate song, title, and station data won’t be needed. LiON has a built-in RDS encoder.

  • MPX SystemLink Wheatstone Baseband 192 - Wheatstone® baseband192 built in for 192kHz digital MPX link to transmitter

  • WheatNet-IP - LiON is part of the WheatNet-IP audio network, with a full-blown interface so you can set up and trigger presets remotely now and add on to your WheatNet-IP ecosystem later.

  • Remote app - Enables you to concentrate on what you hear, not what you see. It’s as if we send a processing expert with each box! The LiON Remote App 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).

  • BS.1770 Loudness Controller - The HD+ processing also includes a BS.1770-compliant automatic loudness controller with a settable LUFS target and full metering of short and long term loudness. 

LiON Remote App

LiON GUI

 

While you can access and adjust virtually all audio parameters through LiON’s multi-tab GUI, you don’t have to. Rather than wade through multiple screens (example: AGC/COMP menu shown above) our LiON Remote App lets you concentrate on what you hear, not what you see. The app makes the tough, behind-the-scenes decisions based on our simple-to-use controls supplied for TEXTURE (Drive, Density, Loudness) and EQ (Low, Warmth, High). It’s as if we send a processing expert with each box!
