1 INTRODUCING THE DMX CONSOLE

hanks for joining the growing ranks of broadcasters

employing Audioarts products designed, manufactured, and

supported by Wheatstone. Throughout our long history

we’ve endeavored to provide the finest quality products,

documentation, and support. To obtain maximum benefit from the DMX

console’s capabilities please read, or at least skim over, this chapter and

Chapters 2 and 3 prior to installing your DMX console. For those in a hurry

a DMX Quick Guide and a Mix Engine Hook-up Diagram (PDF files on

the USB flash drive that ships with the console) summarize the console’s

physical connections, using the software apps, and the Surface controls.

Your DMX console has these main components:

●DMX-8 or DMX-16 Surface –This part is commonly referred to as

the “console” since it sits on the countertop and has all board operator

controls. Figure 1-1 shows a DMX-8 Surface. Each DMX Surface has

these features:

●Fader Channels –There are eight identical fader channels on the

DMX-8 and sixteen on the DMX-16. Each fader channel has eight

push buttons with LED illumination (channel on, channel off, cue

on/off, talkback (TB), and four PGM bus assigns), a color Organic

Light Emitting Diode (OLED) display to show channel status, a 100

mm fader, and a rotary Channel Encoder to select the channel

source. The Channel Encoders are also used to access three the

Advanced Channel Features: audio mode, panning, and EQ &

Dynamics—when not locked out from board operator access.

●Monitor Controls –The console supports a Control Room and an

associated Talk Studio with: CR monitor, CR headphone, Cue, and

Studio Monitor level controls; CR and Studio monitor source

selectors; timer controls; and four console Event buttons.

●Meter Bridge –Three stereo LED meters display the levels for

PGM 1, PGM 2, and a Switched signal: PGM 3, PGM 4, EXT, and

CUE, when enabled. The Meter Bridge also has a four-digit timer,

bus overload indicators, and an On-Air (Hot Mic) indicator.

●Headphone output –A board operator headphone amp is includ-

ed in the DMX Surface with a ¼” TRS jack on the right side of the

chassis, in-line with the OLED displays.

Figure 1-1 DMX-8 Surface

Figure 1-2 Mix Engine, front panel

●Mix Engine –The 1RU Mix Engine (Figure 1-2) has the audio, logic,

and network connections for the DMX console along with the DSP, sig-

nal mixing, and AoIP (Audio over IP) interface functions.

The Mix Engine has these main features:

●5-port Gigabit Ethernet switch to network the Surface and Mix En-

gine, plus three other Ethernet AoIP devices, like the admin PC or

a PC Blade running VoxPro, a Razor I/O Interface, or to connect a

main AoIP gigabit switch to network multiple DMX studios together

●Two low-noise mic preamps, with female XLR inputs, each with

switchable phantom power and input trim control

●Eight stereo/dual mono inputs (four analog and four AES)

●Four stereo program outputs, each with analog and AES output

jacks

●Four stereo analog outputs for Control Room, Studio, Cue, and an

operator headphone output for use with an outboard amplifier

●One 6-port GPIO logic connector

●Installation Kit –The DMX ships with a USB flash drive with PDF

documentation files and the installers for Navigator and the DMX Sur-

face Setup apps which are used to configure the DMX. Navigator is a

licensed application so a separate license must be purchased to con-

tinue using that app beyond the 30-day demo license which is included

with the DMX. Contact Wheatstone support (see page 59) to obtain

your Navigator demo license.

The DMX-8 and DMX-16 Surfaces use an in-line DC power supply so

two IEC AC power cords are supplied for the Mix Engine and the Sur-

face supply. All consoles also include a short CAT5 cable to connect the

Mix Engine’s Ethernet port to Port 5 on the built-in gigabit switch.

DMX OVERVIEW

The DMX console is a compact, self-contained, Audio over Internet

Protocol (AoIP) radio broadcast and production console which uses the

WheatNet-IP (WNIP) networking protocol. Designed for 24/7 operation,

the console has two main hardware components: a 1RU rack mount Mix

Engine, which has the console’s audio and logic connections and a built-in

5-port gigabit Ethernet switch, and a tabletop board operator controller

called the DMX Surface (which most users consider is the “DMX

console”). Both Surface and Mix Engine are fully FCC and CE certified.

DMX consoles ship with pre-assigned IP addresses and a default

configuration so they can be powered up and used right out of the box.

These default settings are changed, to configure the console for use in an

on-air studio, production room, newsroom, or other application, or to

combine multiple DMX consoles into a larger network, using the two

Windows applications included with the console. Using these software apps

is covered in Chapter 3.

Razor I/O Interfaces (1RU, FCC and CE certified) are available to add

audio and logic I/O to any DMX console. Razors use RJ45 jacks

(StudioHub+ convention) for their eight inputs and eight outputs. Razors

have three I/O styles: all analog I/O with two mic preamps (Razor 16A);

all AES I/O (Razor 16D); or half analog and half-AES (Razor 16AD).

Each Razor also has one RJ45 Logic jack with six GPIO ports. A Razor

connects to a port on the Mix Engine’s gigabit Ethernet switch using a

single CAT5e or CAT6 cable of up to 330 feet (100 meters).

Your DMX can be networked with any WheatNet-IP Blade System to

provide additional audio and logic I/O. This may require changes to the

DMX settings (IP address and Device ID) or to the Mix Engine’s Ethernet

switch settings. See Appendix A about configuration settings to support

networking multiple DMX consoles with an existing WNIP system.

DMX Surface

The Surface has eight or sixteen audio control channel strips or Fader

Channels. Three of these fader channels are shown in Figure 1-3, along

with the Monitor Controls which are in two columns of controls. Each fader

channel has a large-knob rotary encoder so the board operator can select

the audio source for each fader channel. A channel status display, just

above the on and off buttons, shows the name of the audio source that’s

currently “dialed up” on that channel, along with other source and channel

status information.

While the channel is off, the channel source may be using the channel

encoder. When touched the channel display changes to show alternate

source names set for that channel, with one name highlighted. Rotate the

encoder until the desired source is highlighted then tap once, or “click” the

rotary encoder to connect the highlighted source to that fader channel.

The signal’s name appears in green in the normal channel display.

Each fader channel can be assigned to any combination of Program

buses using the four assignment buttons just below the channel encoder.

Each fader channel

has a 100 mm fader

for bus level control,

plus eight illuminated

switches (Off, On,

Cue, Talkback (TB),

PGM 1–PGM 4). The

fader channel controls

are identified in Figure

4-2 on page 46.

The two columns of

controls at the right

end of the Surface are

the Monitor Controls,

identified in Figure 4-4

on page 50. The left-

hand column has the

Control Room and

headphone controls.

The three top buttons

select the source

(PGM 3, PGM 4, or

External) going to the

Switched Meter.

A user-defined Soft

button, which has no

default settings, is just

above the six Control

Room monitor select

buttons (PGM 1 –PGM

4, EXT 1, or EXT 2).

These control the

audio feeding the

Figure 1-3 Surface Controls

monitor speakers in the Control Room and the board operator headphone

jack. The Spilt Cue button sets how cue is fed to the headphones (whether

cue even goes to the headphones is set in the DMX Surface Setup app).

The right column has the four Event buttons; two large Timer control

buttons; a Studio Monitor Source Selector (EXT); and a large Talk to

Studio button (TB).

The CUE/SOURCE, CR, STUDIO, and HDPN controls are rotary encoders

used to control the level of the four dedicated monitor outputs on the Mix

Engine. The two Monitor OLED displays show the current levels of those

four outputs and their status (a red X over a bar graph icon indicates that

output is muted). The CUE/SOURCE and STUDIO encoders are alternately

used to assign sources to the various EXT buttons. They are also used to

select and take “wild sources” for the CR and Studio monitor outputs,

respectively.

All Surface controls are on a single field-replaceable Control Panel which

connects to an internal host board using one (DMX-8) or two (DMX-16)

plug-in ribbon cables. This allows for rapid field replacement, with minimal

interruption to operations, in case of spills or other damage to the Surface

controls. Because the program audio flows through the Mix Engine and not

the Surface—except for the audio going to the side panel-mounted

headphone jack, the Surface can be separately powered down from the

Mix Engine without affecting the program audio.

Meter Bridge

An integrated Meter Bridge (Figure 1-4) sits above and behind the

control panel. It has three stereo LED level meters, a four-digit Timer, and

an On-Air indicator. The left meter and middle meters show the Program 1

and Program 2 bus levels, respectively. The right meter is switchable

between showing the other program buses (PGM 3 or PGM 4) or an

External signal (EXT) like an off-air tuner. The switched meter can also be

configured to auto-switch to show the cue levels while cue is active.

The meters normally show both the average and peak levels, but

software settings allow them to be changed to show only the average level

or only the peak levels, for special functions.

Figure 1-4 DMX Meter Bridge

The four-digit Timer is controlled manually, using the Monitor section

S/S button (Timer Start/Stop control), or automatically, when the Auto

Timer button is lit and an audio source, set for Timer Reset (assigned to

specific audio signals using the DMX Surface Setup app) is turned on.

Mix Engine

Audio and logic jacks are on the rear of the Mix Engine (Figure 1-5). This

1RU device has a 5-port Gigabit switch; two high-quality low-noise Mic

Preamps with gain control and 48-volt phantom powering; Signal

Processing with EQ and dynamics applied to any fader channel; eight

audio inputs (four analog and four AES); four Program audio outputs

(four analog and four AES outputting the same set of signals); four

analog monitor outputs to feed powered Control Room and Studio

monitors, powered cue speakers, and an outboard board operator

headphone amp; six GPIO logic contacts, each independently set to

function as a logic input or logic output, and an Ethernet jack to connect

the Mix Engine to the built-in 5-Port Gigabit switch.

Figure 1-5 Mix Engine, rear panel

Input and Output Connectors

All audio, logic, and network connections on the Mix Engine and on the

optional Razor I/O Interface (Figure 1-6)—other than microphone preamp

inputs which have female XLR connectors, use RJ45 connectors and

category wiring (CAT5, CAT5e, or CAT6). Figure 2-4 on page 12 has wiring

pin outs for the RJ45 jacks that connect analog audio, digital audio, and

logic to/from the DMX console. Analog and AES wiring conforms to the

StudioHub+ convention with two balanced analog, or one AES/EBU (AES3)

signal, per RJ45 jack.

The RJ45 Logic jack has six GPIO logic ports plus a +5V and a GND

connection which use the WheatNet-IP logic jack wiring convention.

2 DMX HARDWARE INSTALLATION

ach DMX Surface is 17” (43.2 cm) deep and 4 1/4" (11 cm)

tall. The DMX-8 Surface is 17 5/8" (45 cm) wide. The DMX-

16 Surface is 29 5/8” (75.3 cm) wide.

The Mix Engine (1RU) typically mounts within the studio

cabinetry. DMX components are convection cooled allowing them to be

mounted into any studio, including ones with active microphones, without

adding any environmental noise. When locating the DMX Surface and Mix

Engine, avoid proximity to devices which may generate electromagnetic

fields, such as large power transformers, motors, and audio amps using

switching supplies.

LOCATING THE DMX COMPONENTS

The DMX Surface is intended to set on top of the studio furniture

countertop with its palm rest between six and twelve inches (15 to 30 cm)

from the edge of the countertop (Figure 2-1). This “setback space” allows

keyboards and mice, a VoxPro controller, copy, log sheets, etc. to be set in

front of the console.

The Mix Engine (1RU) is typically rack mounted into a 19” rack located

below the countertop. We recommend adding a 1RU or 2RU vented panel

above and at least one 1RU panel below the Mix Engine for ventilation as it

has a lot of op amps and thus generates a fair amount of heat. Mount the

Mix Engine so its rear panel is easily accessible since that’s where the DMX

audio, logic, and network connections are made.

The DMX Surface comes with an in-line 16 volt DC supply with a captive

DC cable with a locking plug and a detachable IEC AC cord. An isolated-

ground AC outlet must be located below the countertop to allow the six-

foot DC cable to plug into the Surface and the six-foot AC cord to plug into

an isolated-ground AC outlet.

The Surface’s Ethernet port connects to Port 4 on the Ethernet switch

included within the Mix Engine. Use a straight-thru category cable

(customer supplied CAT5e or CAT6 cable).

The DMX Surface is typically just set onto the countertop since its weight

(16 lbs. for DMX-8, 26 lbs. for DMX-16) and four large rubber feet should

hold it in place. If the Surface needs to be fastened to the countertop for

security reasons, a step-by-step procedure is listed in the section

Fastening the Surface to the Countertop, on page 11.

Figure 2-1 DMX-8 Surface, Countertop Positioning

For the cleanest installation, we recommend drilling a one- to two-inch

cable access hole through the countertop for the Surface wiring. Only the

customer supplied CAT5e/CAT6 cable, and the DC power cable/connector

must pass through this hole, so hole size is not critical. The hole could be

sized to match an available hole grommet, or it could be left raw since it’ll

be covered by the Surface.

Here are the steps to drilling the cable access hole:

1. Position the Surface on the countertop so that the palm rest is

parallel to the countertop edge and is setback the desired amount

(typically, between six and twelve inches).
