1 INTRODUCING THE ARCUS CONSOLE
hanks for joining the growing ranks of broadcasters
employing Wheatstone products. Throughout our long
history we’ve endeavored to provide the finest quality
products, documentation, and after-sale support. To obtain
maximum benefit from the Arcus console’s capabilities—and
prior to installing your new Arcus console, read through this chapter, and
Chapters 2 and 3, to get a scope of the installation and console
configuration. For those in a rush, an Arcus Quick Start Guide presents
an overview of the console’s connections and the Surface’s controls and
features. Each Arcus console has these main components:
Arcus Surface –Commonly referred to as the “console” since it has all
the board operator controls on three types of plug-in modules: Fader,
Control, and Master, along with multiple multi-touch monitors. Figure 1-1
identifies the major parts of an Arcus Surface.
Figure 1-1 Arcus-16 Surface
●Fader Modules –An Arcus-16 Surface has sixteen fader channels in
four Fader Modules (Figure 1-1). The Arcus-32 Surface, shown on
this manual’s title page, has thirty-two faders in eight Fader Mod-
ules. Frames with 24, 40, and 48 faders are also available. Each
field-replaceable Fader Module has four fader channel strips. The
Fader Modules plug into the Surface’s Host board using one CAT5
cable to allow for quick field replacement.
Each fader channel strip has:
●One 100 mm conductive plastic, motorized, plug-in fader
●Twenty illuminated push buttons with LEDs for: PFL (Pre-Fade
Listen); AFL (After-Fade Listen); PAGE (toggle channel be-
tween pages); SPILL (to balance the audio channels); SEL (to
select that channel); MUTE (channel on/off); TB (Talkback);
VCA (group level control); AUTO MIX (to add the channel to an
Auto Mix group); A & B (select channel source); ISOLATE (iso-
lates the channel from global page and layer control); plus
four sets of programmable controllers with two select buttons
for user-selected control functions.
●Three color OLED (Organic Light Emitting Diode) displays. The
Channel Info display, just above the fader, shows the source
names for the current page and alternate page. It may also
show master bus assignments; VCA group assignments; and
other source or channel-specific information. The other two
OLED displays show various displays depending upon the func-
tions assigned to the four sets of programmable controllers.
When a fader channel’s SEL button is lit, and the EQ or DYN
Function Expansion button is selected on the Control Module,
these two displays switch to show the various EQ or Dynamics
screens using all four fader channels on that fader module.
●Six rotary encoders, with push-to-take buttons. The top en-
coder adjusts the input level for the current channel source.
Just below that control is a manual channel source selector.
The remaining four encoders are used to select or adjust four
programmable controllers.
●Control Module –The four Wild Fader Mode buttons (VCA, Spill,
Aux Master, and Sub Master) determine what the eight “wild faders”
at the bottom of this module control. The four OLED displays above
the faders display the function that’s active on each fader. Since
there are sixteen VCA, Aux, and Sub masters, the 1-8 and 9-16 but-
tons toggle which set of signals are active on the eight faders. When
Spill is lit, and a fader channel SEL button is lit, the individual chan-
nel balance is set using the Wild Faders. When VCA, Aux, or Submix
is lit, the Wild faders function as master level controls. Sixteen Func-
tion Expansion and monitor control buttons are above the wild fader
controls. Above these controls are four Wild Preset buttons, Page
control buttons, an X-Y router with OLED display, stereo pan, and
delay controls with OLED display, plus ten Layer select buttons to
switch fader channels between up to ten control Layers, each with
two pages. Dedicated copy and paste buttons allow channel settings
to be duplicated and applied to other fader channels. A Loudness
Meter reset button and four meter select buttons are at the top of
the module.

●Master Module –The top right corner has two USB ports for flash
memory sticks: Clip and User. User allows a board operator to save
and recall console configuration files while Clip allows one to play
show elements using the on-screen Clip Player or by using the eight
Hot Clip buttons to the left of the USB ports.
Just below the Hot Clip buttons are Talkback (TB) controls with eight
dedicated talkback buttons and an OLED display to identify the as-
signed talkback destinations. At the right side, four rotary encoders
allow the DIM, TB, AFL, and PFL levels to be set. Four Spare buttons
are user-set for additional functionality in this section of the module.
There are also three dedicated control buttons: AFL/PFL CLEAR, REH
(Rehearse), and AIR. Sixteen programmable (user-set) buttons sep-
arate the upper and lower sections of the module. The lower section
is arranged into four columns of monitoring and Master Bus controls.
Four monitor locations: Studio 1, 2, and 3, and CR (Control Room)
can have any one of six monitor sources assigned using the SEL and
1 –6 buttons. The board operator can also talk to any monitor des-
tination using the TB buttons. Four OLED displays separate the mon-
itor controls from the Master Bus controls. Each is divided in half to
show studio names and levels along with the master bus names. The
two left-hand Master busses are normally set for 5.1 Surround while
the two right-hand busses are Stereo. Each has a motorized 100 mm
fader with output level and gain reduction metering. PFL and AFL
buttons allow any Master bus to be fed pre- or post-Master fader to
the studio monitors. Each monitor can be dimmed (DIM) and the CR
monitor can be switched to feed any combination of three sets of
speakers.
●Touchscreen Panels –Multiple 13.3” (33.78 cm) 16x9 1080p
touchscreen monitors are mounted above and behind the control
modules. The Main Monitor is above the Control and Master Modules.
It’s divided into eight sections to show various level meters in the
Home View. The active monitor View is changed using the fourteen
View Select buttons across the bottom of the Main Monitor.
Additional touchscreen panels, one per pair of Fader Modules, show
channel-specific information, including input and gain reduction lev-
els, delay and input trims, master assign, EQ and Dynamics settings,
and the names of the A and B sources for the eight faders on the
two Fader Modules in front of that touchscreen module.
Gibraltar Mix Engine –The 4RU Mix Engine (Figure 1-2) has the DSP,
signal Mixing, and AoIP (Audio over IP) interface functions for the Arcus
console. It includes these main features:
●QAT Interface card—The right-most card, as viewed from the rear
(Figure 1-2) links the Arcus Surface and Mix Engine together using
two crossover CAT5 cables plugged into Ports C and D. If the Mix
Engine is located over 330 feet (100 meters) from the Surface, the
optional QOT fiber interface card is required.
●GBR Network Card—Its RJ45 jack connects the Mix Engine to the
WheatNet-IP (WNIP) network using a straight-thru CAT6 patch ca-
ble. The GBR card converts the internal console signals into WNIP
system audio streams and logic commands and converts the incom-
ing audio streams and logic commands into the signals used inter-
nally by the Arcus console.
●EQ DSP Card—Has the DSP for the Arcus fader channels. This card
has no rear panel connections.
●Mix DSP Cards—Up to four Mix cards are used for Arcus. These
cards have no rear panel connections.
●CPU—One CPU card comes standard. A second CPU card can be in-
stalled for redundancy, as shown in Figure 1-2. Each has an RJ45
jack to connect that CPU to the WNIP system for communications
and control. Two DARS (Digital Audio Reference Signal) BNC jacks
are available, if needed, to connect a digital clock reference signal,
but for most users these will not be used nor connected.
Figure 1-2 Gibraltar Mix Engine
●DC Power Supply—One supply comes standard. A second supply
can be ordered for redundancy, as shown in Figure 1-2. Each supply
has its own IEC AC jack input to allow the two supplies to be pow-
ered off different AC circuits.
●Fan module—A 1RU fan module (included) must be mounted below
the Mix Engine to provide airflow up through the rack for ventilation.
Leave at least 1RU above the Mix Engine open to allow the hot air to
exit the Mix Engine frame.
Surface Power Supply –A separate 32-volt DC supply powers the Arcus
Surface. A PSR Rack Mount Unit (Figure 1-3 on the next page) and one
SPS-432 slide-in supply come standard. A second SPS-432 supply (an
optional feature) can be added to the PSR Rack Mount Unit for redundant
power. The PSR requires 2RU of rack space. Since the supply is air cooled
from rear to front, equipment can be racked immediately above or below
the supply.

ARCUS OVERVIEW
Arcus is Wheatstone’s flagship television console. It incorporates the
same IP audio innovations as Wheatstone’s AoIP radio consoles and Blades
while maintaining the processing power found in our other TDM-based TV
consoles. Arcus is available in various frame sizes from the Arcus-16 with
sixteen channel faders on up to an Arcus-48 with forty-eight channel
faders. All this control power fits into a compact frame that’s only 46" (117
cm) wide frame for the Arcus-16, or 74" (188 cm) wide for the Arcus-32.
The console’s three main hardware components: Arcus Surface,
Gibraltar Mix Engine, and Surface Power Supply, along with the
optional Stagebox I/O Interface, are all FCC and CE certified.
The Arcus Surface is a compact audio-for-video controller. The fader
channel strips are mounted in Fader Modules which have four fader
channel strips. Each channel strip has a motorized fader, twenty control
buttons, six rotary encoders, and three color OLED displays. The channel
strip controls, along with the controls on the Master and Control Modules,
control the operation of the Gibraltar Mix Engine’s DSP, which contains the
Mixing and signal processing power for the Arcus’s input channels, Master
outputs, Submix groups, and VCA groups. EQ and Dynamics processing
are also available on every input channel along with monitoring controls
for the control room and three broadcast studios.
Designed for use in on-air studios, production suites, and remote
applications, the channel faders have ten layers of control, each with two
pages, to allow for control over even the most complex productions. One
can save and recall configurations for multiple shows and applications on
USB flash drives for instant console setup. All faders are motorized so their
physical positions quickly jump to their settings on each layer and page.
The Arcus integrates seamlessly with all major production automation
systems since it’s powered by Wheatstone’s award-winning WheatNet-IP
(WNIP) audio network, an AES67- and ST 2010-30-compatible IP audio
ecosystem, which allows for on-line Mixing, audio processing, and virtual
development tools including support for direct connection of SIP/VoIP and
codec appliances.
Arcus can access any resource connected to the facility’s WNIP network
using hardware fader channel controls or XY selector on the Control
Module, or thru software XY selectors on the main monitor. Since all Arcus
monitors are touchscreen, a row of intuitive View Select buttons along the
bottom of the main monitor allow one to quickly display various status and
control screens to adjust EQ and Dynamics, set up talkbacks, configure
Mix-minus feeds and bus matrices, assign mic muting and AutoMix group
control, and manage console sources and destinations.
Every fader channel has three OLED displays to show relevant channel
status and for user-set channel control functions. Another eleven OLED
displays on the Control and Master Modules show status and/or levels for
Aux, Sub Mix, or VCA groups, master outputs, monitor outputs, pane and
delay settings, source selection and levels, and talkback destinations.
Arcus’s I/O is entirely through the WNIP network so there are no
limitations regarding fixed connection points on the console chassis itself
since there are none! The Arcus Surface can access any source on the
network, and any channel can connect to any audio source or destination,
using any preferred audio format, at any time—regardless of whether it’s
HD/SDI, AES, MADI, AoIP, TDM, or analog. Unrestricted routing means
any source can be assigned to any channel, as needed. The days of having
to block out channels, based on input type, is a thing of the past, as is
having to repurpose inputs because of physical chassis limitations.
The Gibraltar Mix Engine can be mounted within the Mix room or in
any convenient rack within 330’(100 m) of the Arcus Surface (an optional
Fiber Interface allows for much longer connection distances). Two Mixer
Links (primary & secondary) connect the Surface to the Mix Engine. The
Mix Engine incorporates a WheatNet-IP (WNIP) interface, with a gigabit
Ethernet jack on a GBR card, to stream audio between the Arcus and the
other WNIP devices on the network.
The Mix Engine’s CPU includes DARS I/O to synchronize the Mix engine
with an in-house 48 kHz reference, although these days more often the
network will have a PTPv2 master clock, networked with the WNIP system,
to synchronize the Arcus to a 48 kHz sample rate to synchronize with your
video equipment and ST 2010-30- and AES67-compatible devices.
Each Arcus ships standard with a single output Surface Power Supply
(SPS-432), shown in Figure 1-3. It includes an IEC AC cord and a 16-foot
DC cable with locking connectors to connect the supply to the rear module
DC IN jack on the Arcus Surface.
The Arcus console ships with a factory default configuration so it can be
powered up and used straight out of the shipping crate. The default
settings are easily changed once the console is physical installed and
networked with one or more Wheatstone Blades or the Stagebox I/O
Interface to supply audio I/O for the console. The Arcus can then be
configured for use in a newsroom, production suite, remote van, sports
venue, or any number of other applications, using the two Windows PC
apps included with the console: Arcus Surface Setup and Navigator,

8
and/or by using the touchscreen controls. Chapter 3, starting on page 15,
covers how to use the supplied apps to configure your Arcus console.
Arcus Accessories
Most WheatNet-IP (WNIP) system peripheral devices can be networked
with the Arcus console. Here’s a sampling of the devices available: WNIP
TS-22 Talent Stations for monitoring and talkback, WNIP button control
panels, like the SS-series of rackmount panels with scriptable buttons and
color OLED displays, Wheatstone GP (General Purpose) control panels,
Vorsis audio processors, WNIP-compatible peripherals available from
Tieline, Eventide, and other vendors, and any PC or audio server running
the WNIP AoIP audio driver.
Several WNIP system apps (PC-XY, Meter App, and ScreenBuilder) can
also be used with the Arcus console since it supports ACI (Automation
Command Interface). Wheatstone’s ScreenBuilder app can be used to build
custom screens for remote control of many Arcus functions.
Stagebox I/O Interface (4RU, FCC and CE certified) –Designed for use
on a stage, newsroom, and other location where quick reconfigurations of
mic and line inputs and outputs may need to occur. Each Stagebox has 32
mic/line inputs on XLR jacks, eight AES inputs on BNC jacks, 16 analog
line outputs on XLR jacks, and eight AES outputs on BNC jacks. It also has
one 15-pin D-Sub LIO Logic jack with 12 GPIO logic ports. All connections
are on the front panel of the rack mounted device. Two Gigabit Network
ports, using latching RJ45 jacks, allow for redundant networking of the
Stagebox with the WNIP network.
WheatNet-IP Blades (1RU, FCC and CE certified) –Any model WNIP
Blade can be networked with the Arcus console to add rackmount I/O
anywhere in your plant. There are dozens of Blade models available to
interface just about any type of audio format including Blades with all or
Mixed analog and AES, MADI, or SDI (one SDI Blade can de-embed up to
four SDI inputs). Most Blades have local I/O for 8 x 8 stereo audio signals
and 12 GPIO logic ports on two RJ45 jacks. Most models include the DSP
to host a pair of software Utility Mixers, for quick on-the-fly Mixes, or to
function as an AES67 translator for networking AES67 audio devices with
the WNIP network.
WNIP Network
Arcus consoles “talk WheatNet-IP” which is an Audio-over-Internet
Protocol (AoIP) abbreviated as WNIP. This protocol allows an almost
unlimited number of devices: Arcus consoles, Stagebox I/O Interfaces,
Blades, and other WNIP-compatible devices like PCs and audio servers
using the WNIP audio driver, to share their resources over an AoIP
network that’s both AES67- and ST 2110-30-compatible.
The Arcus Surface’s Host Controller, the Mix Engine’s CPU and GBR
cards, and each Blade and/or Stagebox used for audio and logic I/O, are
networked using one or more AoIP-compatible gigabit Ethernet switches.
Each WNIP device connects to an access port on a gigabit switch using a
straight-thru CAT5e/CAT6 cable which can be up to 330 feet (100 meters)
in length. Multiple network switches can be connected using Trunk Ports to
expand the network’s range, or to create a star topology by connecting
WNIP devices in each studio to a local in-studio switch, which then
connects using a Trunk Port to a main gigabit switch in the Technical
Operations Center (TOC).
Contact Wheatstone sales or support or visit the Wheatstone.com
webpage (Support & Downloads > Compatible Switches for WheatNet-IP)
for a list of recommended network switches. PDF file with configuration
and setup info on many popular switch models are also available.
Appendix A provides additional details about creating a WNIP network.
Because Arcus consoles support WNIP,remote control and monitoring of
the console and just about any point in the WNIP network are available
using various software apps. Most automation vendors support the WNIP
system and specifically ACI (Automation Control Interface) which allows
most existing equipment to be networked with your Arcus console for both
audio streaming and system control by adding a WNIP audio driver to each
PC or server.
Arcus consoles also support WNIP SLIO (Software Logic I/O) which
allows playback systems, talent panels, script engines, and GPIO ports to
send/receive logic commands over Ethernet. To interface “old school”
GPIO devices that don’t support WNIP SLIO each I/O Blade and the
Stagebox have 12 hardware LIO (Logic Inputs/Outputs) ports.
