EMX LogoIP Networkable Console

With EMX, PR&E presents an AoIP networkable console that can handle even the most demanding installations. 

The EMX control surface is a fully integrated standalone console for on-air and production applications. It is available in three Surface frame sizes that hold 16, 20, or 28 fader channels 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.

EMX16 OVHD v8 SIL FLAT

The 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, Telco Record, two user-set 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 set to show Cue levels while Cue is active. A count-up timer and stereo cue speakers are also included.

Each channel has a large-knob “Channel Encoder” (the Magic Knob) to select a new channel source and, if enabled for operator use, access to the built-in Advanced Channel Features: audio mode, panning, EQ & Dynamics, and Aux Send levels, which are included on every channel. Each fader channel also has three user-set “Soft” buttons to customize channel functionality, plus cue control and two buttons (Talkback and Auto FB) which simplify taking calls and doing live remotes. The Monitor Control panel buttons and controls support the Control Room, an associated Studio, and an External location, along with having the controls for the built-in timer and to save and recall console Events.

The PR&E Mix Engine

EMX uses the PR&E Mix Engine, with its 1 Gb connectivity and built-in 5-port Ethernet switch, to allow 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 EMX and DMX consoles. EMX supports WheatNet-IP logic-over-IP, as well as ACI (Automation Control Interface), so any WheatNet-IP-supported radio automation server can also be networked with the EMX—no additional audio or logic wiring required.

DMX16 ENGINE FRONT& REAR

The 1RU PR&E Mix Engine is the heart of the EMX, housing its audio and logic I/O, and its signal processing and mixing DSP. The EMX Surface connects to the Mix Engine using one Ethernet cable (connected to Port 1 of the built-in Ethernet switch) to communicate with its Mix Engine and to receive AoIP streams for its meter bridge cue speakers and board operator headphone jack on the right-side of the Surface.

The PR&E Mix Engine includes two high-quality low-noise mic preamps and a five-port Gigabit Ethernet switch so no external AoIP switch or other hardware is required when the EMX is stand-alone or used in a smaller facility.

All of the EMX console’s sources and destinations are available to connect to every other networked PR&E AoIP device (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.

All AES3 and line-level analog audio connect using RJ45 jacks (StudioHub+® compatible) and CAT5 cables for fast crimp-free/solder-free connections. There are 28 RJ45 jacks on the Mix Engine’s rear panel along with two female XLR jacks for:

  • Two Microphone inputs (XLR jacks) with switched 48-volt phantom power and gain trim on each preamp.

  • One Dual mic preamp output jack (connect a short CAT5 jumper to any analog input to use one or both mic preamps).

  • Eight Stereo inputs: four balanced analog and four AES3 (any input can be set to be dual mono inputs).

  • Eight Stereo outputs (set for PGM 1, PGM 2, PGM 3, and PGM 4 from the factory), each has a balanced analog and AES3 jack. Any output source can be changed, as needed, using the PR&E Navigator app.

  • One Six-port GPIO Logic uses the WheatNet-IP RJ45 jack logic convention.

  • Four Stereo analog monitor outputs for powered Control Room Monitors, Studio monitors, external Cue speakers, and a guest Headphone amplifier. Sources on unused outputs can be switched, using the PR&E Navigator app, to create additional local stereo outputs.

  • One Mix Engine Ethernet Port (short CAT5e jumper, included, connects to Port 5 on the Ethernet switch).

  • Five Ethernet ports, on the built-in Gigabit Ethernet switch, network the Surface and Mix Engine along with three additional networked devices: Razor AoIP Signal Interfaces, a setup PC or a VoxPro PC running WheatNet-IP audio drivers, another EMX or DMX console, an M4IP-USB BLADE (licensed for PR&E use), or a main facility AoIP switch.

Cool Stuff About EMX
Original features for today's broadcast facilities


No External Switch Needed

NoSwitches

With the PR&E Mix Engine, we’ve provided five Ethernet ports for interfacing the Surface, the Mix Engine, your PC for use with PR&E Navigator or EMX Surface Setup, as well as optional devices such as VoxPro PC, a media server, or a couple of Razor I/O Interfaces for expansion. Essentially acting as a built-in switch, this keeps IT management and procurement costs down while making it dead simple to expand your AoIP network.

Of course, if you DO want to expand even further and add more EMX and DMX consoles, you can add a WheatNet-IP-certified Gigabit switch and be off and running to a larger network.

ContstructionRobust Steel Construction, Made in USA

We’ve built the EMX to withstand years of use and abuse. The finest components and the most reliable construction come together to create a surface that any station would love to have in their on-air studio or control room and production suites.

Source and Program Select DMX MasterStripDetail

Any channel can be assigned to any combination of the four Program, two Auxiliary, and Off Line buses, making your material available to an on-air feed as well as an Internet stream, for instance.

SourcePgmSelectAny audio signal, whether connected to the EMX or to a networked Razor, PC, or another EMX, can be a source on any fader channel. While doing this allows for complete flexibility, in practice it’s better to “trim the list of sources,” which the EMX Surface setup app does in the channel “Visibility list.” This allows channels with dedicated sources, like the board operator mic, the automation server playback channels, and the phone, to just see those sources, whereas you always need a couple “RLS” faders where just about every signal is listed.

 

Full Parametric EQ and Dynamics Processing on Every Channel

OLEDs for Page AgainEQ

The EMX has 4 fully parametric EQ bands with peak/shelf control for the low and high bands plus high and low pass filters - on every channel. Same with compression, limiting, and expansion dynamics control - a full suite on every channel. When the EQ & Dynamics feature is active, multiple OLED channel displays are simultaneously switched to show the various EQ & Dynamics screens, simplifying how one edits their settings.

With full color OLED displays and color-coded functions, you can see all your settings at a glance. Shown are just a sampling of the displays available on the EMX.

Cue and Talkback

EMX Cue TB

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 on the Mix Engine. Settings in the EMX Surface Setup app allow cue to feed any combination of the headphones, the studio monitor output, and even the control room monitors. TB (talkback) is a momentary button that allows the board operator to talk to a caller or a remote. Needless to say TB does nothing if the source is not a caller or remote.

Off Line and Auto Foldback

OffLine

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 each caller’s or remote’s bus-minus signal. Off Line is used to allow for hands-free interaction between the board operator and a caller or remote. When Off Line is lit, that fader channel is feeding the Off Line bus.

The Auto FB button allows the caller or remote channel status to control their bus-minus audio. When their channel is Off, Off Line is sent to the bus-minus so the board operator can freely interact with them. Then, when their channel is turned on, the bus-minus auto-switches to the on-air PGM bus (typically PGM 1) so the caller or remote can hear everything else going to air, but minus their own audio, of course.

The Magic Knob

MagicKnob

This single multi-function knob at the top of each channel provides quick, intuitive control over: console audio mode; channel panning/balance; channel EQ & Dynamics settings; and over the levels feeding the Aux 1 and Aux 2 Sends. The channel’s OLED display shows relevant information for each Advanced Channel Function, except for EQ & Dynamics—multiple channel OLEDs switch to show the EQ and Dynamics screens while that function is active. Access can be controlled so that so that basic settings are protected from board-ops if desired.



Literally Plug & Play...

1. Using standard CAT-6 cables, plug the EMX surface and engine into the built-in switch on the Mix Engine.

2. Plug in the PC or audio server, running the PR&E Navigator and EMX Surface Setup apps, to easily configure the network, edit the default settings, and setup the Surface to match your application.

3. If you like, add one or more Razor I/O Interfaces or M4IP-USBs to add more sources and destinations to your EMX.

4. Plug your own audio sources into the PR&E Mix Engine and Razor(s).

5. Turn it all on and hit the airwaves.

 

To network the EMX with a larger facility, connect a CAT6 cable from the Mix Engine’s Ethernet switch to any WheatNet-IP-compatible Gigabit switch. EMX sources are then immediately available to stream to any number of other EMX and DMX consoles, Razor I/O Interfaces, M4IP-USB mic/voice processors, PCs and servers running WheatNet-IP audio drivers, AES67-compatible devices, and even WheatNet-IP Blades (when licensed for cross-networking).




Channel & Monitor Controls


Input Panel

Multi-Function Encoder Knob (The Magic Knob) 
When the channel is off, rotating the encoder switches the channel display to show alternate sources, selected by “clicking” the encoder. The encoder can also control channel mode, pan, EQ & Dynamics, and AUX send levels.

SOFT
These buttons have no preset assignments. They are set, using the EMX Surface Setup app, for channel-specific functions like a hot source take button, EQ on/off, or Aux Send on/off.

PGM Assign
Directs the channel's signal to any of four stereo output busses.

OFF LINE
Assigns the channel to the Off Line bus, used with callers and remotes.

AUTO FB
Only active when the source is a caller or remote to switch their bus-minus audio between Off Line (channel off) to a PGM bus (channel on).

CUE
Places the fader channel audio into the CUE mix.

TB
Only active when the source is a caller or remote which allows the board operator to talk to that caller or remote.

FADER
100mm Long-throw fader for channel level control.

OLED Display
Normally shows fader channel source and status icons but changes display when other functions are being used such as MODE, PAN, EQ/DYNAMICS, AUX.

ON/OFF
Switches the channel’s audio on and off as well as issuing start/stop LIO functions.

EMX INPUT PLANEL

Control Room Panel

CR/HDPN Select Encoder
Rotate to choose a wild on-the-fly monitor source (visible names listed in the OLED) then press to Take. Also used to select a source when assigning the EXT 1, EXT 2, EXT 3, and TEL buttons.

CR/HDPN Monitor Source Select Buttons
The EXT 1, EXT 2, and EXT 3 buttons are user-set, using just the panel button and the encoder, to assign an off-air tuner, pre-delay audio, and other source to the button. The Tel button, pre-assigned to the Telco Record bus, can also be user-set to a different source if desired. The four PGM Monitor buttons allow any main Program bus (PGM 1, PGM 2, PGM 3, or PGM 4) to be instantly monitored.

Split CUE
Affects how cue is fed to the HDPN output when Cue-to-HDPN is enabled in the EMX Surface Setup app. When unlit, and cue is active, cue is fed to the HDPN outputs in stereo, cutting off the monitor audio. When lit, and split cue is active, the monitor source is summed to one ear and cue is summed to the other ear.

CR Fader
Controls the level of the Control Room monitor speakers (CR OUT on the Mix Engine).

HDPN Fader 
Controls the monitor level to the Surface headphone jack and to the HDPN OUT jack on the Mix Engine.

CR and HDPN OLED Display
Shows the current date above the white line. Just below the white line, the current monitor source for the CR and headphones is listed. At the bottom of the display are bar-graphs indicating the levels of the CR monitor and HDPN faders. When the CR source selector encoder is rotated, the display switches to show the visible monitor source list for the control room.
