LX-24 In Depth



LX-24 works with the WheatNet-IP Intelligent Network, utilizing BLADE interfaces, to access, control, and process any and all audio sources on the network. Through AES67, it's compatible with similarly equipped third party gear, providing functionality for your facility that is unequalled. 


LX-4 Guy

While it’s a feast for the eyes, its core design elements are what make Wheatstone’s LX-24 really stand out. For starters, it’s conceived for people who work in radio. Pull up a chair and you’ll feel right at home.

The LX-24’s totally modular design lets you configure it exactly as you like. And you can hot-swap any module at any time. There are no electronics in the pan below the modules – in the event one needs to be replaced, simply reassign the audio to another module and you’re up and running in seconds. Pop in a replacement module at your convenience. It’s that simple.

The LX-24 can be anywhere you need. It’s already part of the WheatNet-IP Intelligent Network – the IP88E Mix Engine BLADE provides audio mix functionality and can be anyplace on the network. Additional BLADEs can be added for inputs and outputs in a variety of digital and analog formats, and this I/O can be shared with other consoles and devices, such as AirAura and Aura8-IP, throughout the Intelligent Network. The LX-24 is an intelligent surface that can store and recall all your settings. It even remembers settings if you have to hot-swap a module. Snapshots of the LX-24’s configuration can be saved and recalled at the touch of a button, making setup for different shows or dayparts a snap.

The LX-24 modular control surface has a low-profile, table-top design that allows it to fit into almost any studio situation. The meterbridge features up to four sets of bright, high resolution LED meters, as well as circular LED displays for auxiliary send levels and pan control. A digital count-up/count-down timer is also included.

Each input channel can be assigned to four stereo busses, plus four pre/post-selectable aux sends, a stereo CUE bus, four mix-minuses and the panel’s own bus-minus. An LED source name display, an A/B source selector, and two programmable soft buttons are included and a SET button provides access to assignable controls in the master section.

Control room and headphone outputs with level control and source selection are provided, as well as two independent studio monitor outputs. Stereo CUE speakers are built into the meterbridge. Headphones and CUE are delivered to the surface right from the IP network, so there’s no tying up BLADE outputs for the headphone and cue audio.

On-board VGA and USB-Mouse connectors allow a monitor and mouse to be connected to the console for configuration and advanced console functions.

As with all Wheatstone products, the LX-24 is made in the USA at our New Bern, NC facility and is supported by Wheatstone on both sides of the country (and around the world).

It was time to raise the bar for radio consoles. Who better to do it than Wheatstone?

The Details
 

Meterbridge

Behind the LX-24’s beauty is tremendous functionality. Exceptionally fast and accurate, the level LED meters feature an overload indicator that glows blue when the signal is within 3dB of clipping. There are also 4 very cool circular LED displays that indicate auxiliary send levels. Below those are an LED indicator for pan control and a digital count-up/count-down timer.

A modular control surface that’s completely customizable for your applications

The LX-24’s design features stainless steel switchguards on the ON/OFF switches and long-life sealed contact switches that are LED illuminated. Its modular construction allows you to customize its layout and functionality. Every module is hot-swappable, meaning that there’s never any downtime if you need to add, change or replace one. Have as many input modules as you need. Want more programmable buttons? Just add another Accessory module. There are no electronics beneath the modules in the LX-24, so the likelihood of an accidental spill taking the board out is minimized. And there are several frame sizes to choose from to get the exact size you need.

LX-24 Buzz from Some Pretty Heavy Hitters in Radio


“I didn’t think Wheatstone could improve upon the E-Series of consoles, but they have done it with the new LX-24. This is a beautiful, well designed console and the individual faders, integrated meters with overload indicators and low profile table-top design make this a must have for our facilities.”

Michael Cooney, Vice President of Engineering & CTO, Beasley Broadcast Group, Inc.


“A high performance, reasonably priced, great looking console integrating common sense features such as overload indicators for meters and ergonomic controls. Very impressive and well thought out.”

Benjamin Brinitzer, Regional VP Engineering Clear Channel Media & Entertainment


“Wow! Wow!”

Rick Hunt, Vice President & Director of Radio Engineering, Entravision Communications Corporation


“I am very impressed with the sleek new design that incorporates single channel-strip architecture, integrated metering and stereo cue speakers in a thin, sloping chassis that needs no cabinetry cut out. Well done.”

Erik Kuhlmann, Senior Vice President of Engineering, Clear Channel Media + Entertainment


“By far the most elegant and feature rich control surface on the market. The attention to detail and functionality is remarkable. Its architecture, such as “hot swappable” modular design, is a winner. A traditional meterbridge is appreciated by users and your millwork guy will appreciate the fact that it’s a table-top design.”

Kris Rodts, Director of Engineering, IT & Facilities, CKUA Radio Network


“The LX caught my attention on the NAB Show floor. The look, form and function are unlike any other IP console available today. The easy-to-read buttons and displays are just second to none, not to mention the most bang for the buck. I can’t wait ‘til I have the opportunity to deploy my first LX.”

Anthony A. Gervasi, Jr., Sr. Vice President Engineering & Technology, Nassau Broadcasting


“Cool and sexy (I sound like Bruno from Dancing with the Stars). A great addition to the WheatNet-IP family.”

Norman Philips, Vice President of Engineering, Townsquare Media


“Considering the LX-24’s attractive good looks, modularity, traditional console layout and functionality, I can’t wait to get my hands on one!”

Greg Landgraf, Senior Engineering Manager, Corus Radio Western Canada



“Leave it to the exquisite design talents of Gary Snow and the Wheatstone team to really hit the nail on the head. The LX-24 is not only the most functional, feature-laden IP based console for radio, it also raises the bar for the finest ergonomic radio command center on the planet.”

Tim Schwieger, President / CEO, BSW- Broadcast Supply Worldwide


“Wheatstone’s innovation continues to make AoIP a viable product for professional broadcasting facilities. Just a few things that make the LX-24 stand out to me are the clear and decisive metering, individual fader modules, and “out of the box” thinking with faders for the headphone and monitor volume controls instead of rotary knobs.”

Phillip Vaughan, Chief Engineer KFROG, CBS Radio


“Wheatstone continues to hit balls out of the park and this year they did so again with the LX-24 control surface. This new product marries the best of the old (modular design architecture) with the new (Audio-over-IP). Continuing in that theme was a Wheatstone module that marries their bridge router system to the new “BLADE” audio-over-IP system. This has the potential to extend the life of bridge router facilities indefinitely.”

W.C. Alexander, CPBE, AMD, DRB, Director of Engineering, Crawford Broadcasting Company
