Opening new networking opportunities to the TV audio world. Any source, anywhere, any time.
Considered the workhorses of the industry, Wheatstone television audio consoles keep more stations reliably up and running than any other consoles in the world. From our largest to our most compact, all are considered the most intuitive AND the most comprehensive you can buy.

D4 LH ANGLED CROP v7The Series Four features 24 motorized input faders (the Series Two features 16 on a smaller frame), two main mix busses, four subgroups, up to 48 channel mix-minuses, four mix minus busses, and two AUX sends, plus extensive processing. All input channels have 4-band parametric EQ sections, tunable high and low pass filters, and compressor/limiters, plus expander/gate and programmable delay for lip-sync correction.

And unlike sound reinforcement consoles, these consoles each offer a direct bus-minus feed with IFB from each channel plus four front panel assignable mix-minus busses. With a possible total of 52 outputs, all IFB needs should be more than covered, and the common bus selection function provides tremendous flexibility in how IFB is managed.

Through our Automation Control Interface (ACI), the Series Four and Series Two integrate seamlessly with production automation systems so operators can, for example, change routing or automatically crossfade between inputs as the switcher or automation system cuts or dissolves between video sources. Faders can be mono, stereo or surround. What’s more, all the mixes generated by the Series Four and Series Two can be routed to any available outputs on the audio network, including input faders on other network-connected control surfaces. Assign any source of any type to any fader, and share I/O resources with other consoles in the network. It’s all networked through Wheatstone’s Gibraltar Network system, utilizing Wheatstone’s powerful Gibraltar mix engine technology with 1,024 DSP processing signal paths. This kind of power and modular flexibility provides the extra redundancy that is so critical to broadcast operations, with auto-failover DSP processing on the board and the kind of I/O connectors that stand up to the broadcast environment, not to mention easy touchscreen setup.

These consoles can take it all in – analog, AES, MADI and HD/SDI input signals – and deliver any source or console bus to any destination in the broadcast network. Operators will be able to see it all, too, on a large, high-resolution multifunction touchscreen display for capturing information at a glance: metering, channel/bus assignments, and programmable control functions. A LKFS meter for loudness monitoring is also included in the main display.

The Series Four and Series Two are priced comparably to semi-pro live sound/recording mixers, and they won’t paint broadcasters into a corner should they ever want to add I/Os, mix-minus feeds, or any number of broadcast-specific functions. Like all Wheatstone television audio consoles, the Series Four and Series Two are control surfaces; all audio I/O is housed in the Wheatstone Gibraltar Network rackmount router/mixer.

Because Series Four and Series Two are networked consoles, you can:

• Assign any source of any type to any fader
• Hot-swap components without powering down or disassembling
• Share I/O with other networked control surfaces
• Control the consoles over IP with any of the major newsroom automation systems
• Switch live, on the fly or between air and protect sources on the same fader

Utilizing the Wheatstone Gibraltar Network audio networking technology, the Series Four and Series Two can be configured with any combination of analog and digital inputs. Those inputs can be mono mic or line, stereo, or 5.1. Stereo and 5.1 surround output busses allow you to feed both your HD and SD program streams with no fuss.

S24 Page ButtonPage Function Doubles Your Capabilities

With the Series Two or Series Four page funciton, you have double the number of input channels - each having access to any source or destination on the network - without increasing your footprint by a single inch. Simply press the page button on any channel to call up that channel's other page. The motorized fader will snap to its current position and all accessible settings will follow. It's like getting a free add-on control surface.


The Integrated Touchscreen Graphical User Interface

Metering, and control of all secondary functions, is via the large touchscreen. The navigation buttons at the top of every screen will take you instantly HOME to the MAIN screen, to INPUT setup (level, EQ, dynamics), MIX-MINUS, BUS-MINUS, INFO, or EVENTS. Every function is just a click or two away.


S4 Main screen with LKFS v2

Main Screen 

The upper half of the main screen is dominated by large high-resolution meters for every monitor, aux, group and master output. A pop-up LKFS loudness monitor toggles with the four group meters. Note the master output meters at the upper right (5.1 surround and Stereo Two)—these drill down to occupy the same position on ALL touchscreens regardless of selection, keeping the operator aware at all times of on-air output levels.

The screen’s lower half displays metering of input levels for the sources assigned to each of the 24 input channel strips. A fader knob imposed directly on each meter lets you quickly adjust input gain sensitivity to optimize source levels.
Below the input gain meters and touchscreen faders are the input channel strip indicator/buttons. Color indicates status: channel ON, ON-AIR, and OFF. A central PAGE button toggles the screen to inputs 25 through 48. Pressing a button puts that input into SET mode, switching to the INPUT screen for that channel strip, where you have complete control over all input channel parameters (levels, EQ, delay, panning, dynamics, bus assign, etc.). Once settings are complete, pressing the button again returns you to the MAIN screen.

Input Screen 

Pressing a channel indicator button at the bottom of the MAIN screen opens up the first of five possible INPUT screens.

S4 InputScreen01Filter

Comprehensive input-related settings and status indication: mode, input gain and level, stereo pan, high and low pass filtering (removes unwanted LF and HF energy), adjustable input delay (for precise sound/video alignment), phase reverse, bus-minus/direct out setup, and mute assignment.

S4 Compressor Screen10Compressor/Limiter

Compressor/limiter provides smooth inaudible level control, peak control, or can be used to dramatically change and enhance the audio. Controls include threshold, ratio, attack, release, and makeup gain. Can be inserted pre or post EQ. Lower portion of screen displays readouts, VU/GR metering and X-Y visual graph.


S4 Gate Screen09Gate

Complete control of all gating parameters: threshold, depth, open, hang and close. The lower portion of the screen has precise readouts of all settings, VU and gain reduction metering, plus an X-Y visual graph (input vs output) of the resulting signal settings.

S4 EQ Screen02EQ

Four-band parametric equalization, each with adjustable frequency, width, and boost/cut. High and low bands can be peak or shelving. A full frequency visual graph depicts the resulting EQ curve.

S4 Pan Screen03Pan/Surround

Complete panning control of all mono and stereo sources. Full 5.1 spatial manipulation of surround sources. Place your sound exactly where you want it.


S4 Info Screen06Info

Info is a non-interactive popup information display directly available over any touchscreen selection. It provides detailed system information: status, software version, MAC and IP addresses, memory usage, etc.

S4 MXM Screen04Mix-Minus

Mix-minus outputs—each with a separate build of sources—are used for intercom, phone coupler, ISDN, and remote truck feeds. This screen has level controls and meters for the console’s four MXM busses, as well as the two console AUX SEND busses. TALKBACK buttons are provided for all six mixes. An assignment grid at the bottom of the screen allows crosspoint setups between the four MXM busses and individual input channels.

S4 BusMinus Screen05Bus-Minus

Bus-minus is an individual output for each input channel strip, also known as N-1. This allows talent to get an independent monitor/IFB feed; the TB button on each input channel strip talks to that bus-minus output. These same outputs can be configured as a direct out, pre or post. Mix- and bus -minus outputs make the Series Four and Series Two powerful and flexible consoles for live television news, talk shows, sports, drama, and special events.

S4 Event Screen07Events

The Series Four and Series Two are capable of creating, storing and recalling up to 99 named events—control surface snapshots of various console configurations and show setups. Using this screen, events can be created, called up, edited and activated. Access visibility and editing privileges can be programmed at an administrative level to prevent unwanted mishaps. A popup keyboard makes naming events quick and easy.


Modern design for today’s production, broadcast and automation systems

Series Four and Series Two are made to work with today’s production automation systems – their control interfaces are compatible with all the major automation systems on the market. Yet, they also have all the important broadcast-specific features, such as automatic studio muting, machine control logic, de-embedding inputs, 5.1 surround capability, balanced or unbalanced AES inputs, router integration, and flexible monitoring capability.

Failsafe Redundancy

It’s all about staying on the air - every second of every day - without fail

Wheatstone’s experience in designing audio consoles for all broadcast realms as well as pioneering networking comes together in the Series Two/Series Four. More power to handle modern needs with a user interface that is pure joy to get your hands on. And with Wheatstone’s built-in safeguards, you can rest assured that you’ll always be on the air...with or without fail.

Redundant Components

Gibralter DSP CardIf a DSP chip fails in a traditional console, it tends to take the entire card with it, leaving the board dead. Thus, having a backup DSP chip on the same card is not really a solution. With Wheatstone, a hot-spare DSP card can be utilized with automatic failover in the event of a problem with the primary engine. Because any source can be assigned to any fader, even catastrophic damage to a fader module on the console (as from a drink spill or falling object) only means that the damaged faders are out of action. The sources can be rerouted to other faders, and the show goes on.

Redundant Power


Gibraltar Network cage utilizes internal modular power supplies and can accommodate up to two units for redundancy.

On the Gibraltar Network and Gibraltar IP Mix Engine cages, power supplies are internal and can be single or dual modules.

The back provides access to the cards’ connections.

Gibraltar: Create a System with IP-Based Audio Network or Traditional Networked Router Frame

Wheatstone has long been the leader in networked audio and routing for broadcast. Whether you are interested in a traditional frame-based TDM network or are looking at an IP-based system that can utilize AES67 to function with emerging standards, Wheatstone has mature, field proven, bullet-proof networking that provides the functionality to make the most of your applications and needs.

Gibraltar brings an exceptionally powerful engine to the mix. There are 1,024 channels of DSP available. For a modern studio, consider that for every input you’ll need a minimum of 6 channels of processing for 5.1 surround as well as 2 channels for stereo processing. Add to that processing for all major output and monitor busses (stereo and surround mains, submixes, aux sends, mix-minus, tracks, control room, studios and headphone feeds) and you’ll see that it adds up to a lot.

Each of our consoles taps the power of Gibraltar to provide unparalleled mixing capabilities and most can be ordered with a traditional TDM-based Gibrlatar Network with a cage that allows you to choose cards for your specific installation, or an AoIP-based Gibraltar IP Mix Engine in which most of the same functions are accessed via our BLADE-3 interface boxes.
