With the Wheatstone EMX, PR&E presents an AoIP networkable console that can handle even the most demanding installations. The Wheatstone EMX control surface is a fully integrated stand-alone console for on-air and production applications. It is available in three surface frame sizes that hold 16, 20 and 24 fader channels (with optional wide frames for adding accessory panels) and features four stereo program buses, two stereo auxiliary buses and a bus-minus system that allows Telco (mix-minus) devices to be used on any fader. The Wheatstone EMX meter bridge has dedicated meters for the PGM 1, PGM 2 and PGM 3 bus signals, plus a switched meter to show levels for PGM 4, telecom register, two user-defined external signals or a wild on-the-fly selection. The meters can show Average Only, Peak Only or Average and Peak levels. The switched meter can also be configured to show Cue levels while Cue is active. A countdown timer and stereo speakers are also included. Each channel has a large “Channel Encoder” (the Magic Knob) for selecting a new channel source and, if enabled for operator use, accessing the channel’s advanced features: audio mode, pan, EQ & Dynamics and Auxiliary Send Levels, which are included on all channels. Each attenuation channel also has three user-defined “Soft” buttons to customize the channel’s functionality, as well as signaling control and two buttons (Talkback and Auto FB) that simplify making calls and performing live remote controls. The buttons and controls on the Control Monitor panel support the control room, an associated Studio and an external location, as well as having integrated timer controls and saving and recalling console events. The PR&E Mix Engine The Wheatstone EMX uses the PR&E Mix Engine, with its 1Gb connectivity and integrated 5-port Ethernet switch, to allow WHEATSTONE EMX sources to be shared with any networked device (and vice versa), including Razor I/O interfaces, the M4IP-USB Blade, Windows PCs running the WheatNet-IP audio driver and other Wheatstone EMX and DMX consoles. Wheatstone EMX supports WheatNet-IP logic over IP as well as ACI (Automation Control Interface), so any radio automation server supported by WheatNet-IP can also be networked with Wheatstone EMX – no additional audio or logic wiring is required.
The 1RU PR&E Mix Engine is the heart of the EMX, housing its audio I/O and logic and its signal processing and DSP mixing. The EMX Surface connects to the Mix Engine using an Ethernet cable (connected to port 1 of the integrated Ethernet switch) to communicate with your Mix Engine and to receive AoIP streams to your cue meter speakers and board operator headphone jack on the right-hand side of the Surface. The PR & E mixing engine includes two high-quality, low-noise microphone preamps and a five-port Gigabit Ethernet switch so that no external AoIP switches or other hardware are required when the EMX is stand-alone or used in smaller installations. All EMX console sources and destinations are available for connection to all other networked PRI E devices (and vice versa) – from DMX consoles and Razor Signal Interfaces to other EMX consoles, along with any networked M4IP-USB Blades (licensed for PR&E use) and any VoxPro or other PC running the WheatNet-IP audio drivers.

Extending EMX
The EMX uses the PRo-IP AoIP network, based on the WheatNet-IP protocol, to access, control and process any and all audio sources on the network. Each of the Razor I/O interfaces shown above provides 8 analog, digital or analog/digital inputs and outputs, as well as logical and Ethernet connections on RJ45 connectors.
Extending EMX’s surface functionalityThe EMX is pre-configured to install and interface an optional TELCO panel when requested using an EMX Wide Surface. The SS-8 programmable button panel is also available as an option. The buttons can be scripted to perform a large number of tasks and have integrated OLEDs so you can customize their appearance.

No external switch required
With the PR&E Mix Engine, we provide five Ethernet ports to interface the Surface, the Mix Engine, the PC for use with PR&E Navigator or EMX Surface Setup, plus optional devices such as the VoxPro PC, a media server or a pair of razor I/O interfaces for expansion.Essentially acting as a built-in switch, this keeps IT management and acquisition costs down, making it simple to expand your AoIP network. Of course, if you want to expand further and add more EMX and DMX consoles, you can add a WheatNet-IP certified Gigabit switch and be off and running for a larger network.
Robust steel construction, made in the USA We built EMX to withstand years of use and abuse. The best components and the most reliable construction come together to create a surface that any station would want in their studio or control room and production suites.

Any channel can be assigned to any combination of the four Program buses, two Auxiliary buses and Off Line, making your material available for an on-air feed as well as an Internet stream, for example.
Full Parametric EQ and Dynamic Processing on All Channels Suggestion and Talkback
Any audio signal, whether connected to the EMX or to a Razor, PC or other EMX, can be a source on any fader channel. Although this allows complete flexibility, in practice it’s better to “trim the source list” that the EMX Surface configuration application makes in the “Visibility list” channel. This allows channels with dedicated sources, such as the board operator’s microphone, the automation server’s playback channels and the telephone, to see only those sources, whereas you always need some “RLS” faders on which virtually all signals are listed.

The EMX has 4 fully parametric equalization bands with peak/shelf control for the low and high bands, plus high and low pass filters – on all channels. The same with compression, limiting and dynamics expansion control – a complete set on all channels.When the EQ & Dynamics feature is active, multiple OLED channel displays are switched simultaneously to show the various EQ and dynamics screens, simplifying the way settings are edited. With color OLED displays and color-coded functions, you can see all your settings at a glance. Shown are just a sample of the displays available on the EMX. 
Cue, when lit, sends that channel’s audio (pre-fader and pre-on) to the built-in cue speakers and to the cue monitor output in Mix Engine. The settings in the EMX Surface Setup application allow the cue to feed any combination of headphones, the studio monitor output and even the control room monitors. TB (talkback) is a momentary button that allows the forum operator to talk to a caller or a remote control. Needless to say, TB does nothing if the source is not a caller or remote control.
[/vc_column_text] [/vc_column] [/vc_row] [vc_row] [vc_column width=”1/2″] [vc_column_text]Off Line and Auto Foldback
The Off Line and Auto FB (Foldback) buttons are used exclusively with callers and remotes to control which bus (Off Line or a PGM bus) is feeding the bus-minus signal of each caller or remote. Off Line is used to allow hands-free interaction between the panel operator and a caller or remote control. When Off Line is lit, this fader channel is feeding the Off Line bus. The Auto FB button allows the status of the caller or remote channel to control its audio without the bus. When your channel is Off, Off Line is sent to the bus-minus, so the board operator can freely interact with them. Then, when the channel is ON, the bus-minus automatically switches to the PGM bus on the air (usually PGM 1) so that the caller or remote can hear everything else going on the air, but minus their own audio, of course.
[/vc_column_text] [/vc_column] [vc_column width=”1/2″] [vc_column_text]The magic button
This unique multi-function knob at the top of each channel provides quick and intuitive control over: console audio mode; channel panning / balancing; channel EQ and Dynamics settings; and over the levels feeding the Aux 1 and Aux 2 Sends. The channel OLED display shows relevant information for each advanced channel function, except for EQ and Dynamics – the multi-channel OLED switch shows the EQ and Dynamics screens while that function is active. Access can be controlled so that basic settings are protected from board operations, if desired. [/vc_column_text]
