It’s a good bet
there’s not a single
person in America,
who’s listened to the
radio in the last
10 years, who
hasn’t heard an
Audioarts radio
console in action.
That’s how pervasive
and powerful this
product line is.

Wheatstone D-75
STANDALONE DIGITAL AUDIO CONSOLE
When it comes to radio consoles, Wheatstone’s Audioarts is
the de facto standard. And our D-75 is the state of the art.
It’s got everything you need to produce, air and manage all of
your programs. It’s powerful and flexible enough to please any
engineer, simple enough that even guest talent feel at home and
cost-effective enough to make management smile.
Available in two frame sizes, 12 input (13 max) and 18 input
(21 max), the D-75 comes standard with 4 mic preamps and
gives you plenty of stereo busses, dual phone caller capability
and a comprehensive monitor section that provides separate
feeds to control room/headphone and studio monitor outputs.
Plus, the D-75 gives you an output module, external power
supply, two LED meter pairs, digital clock and timer, headphone
jack, and built-in cue speaker (dual phone module and line
selector module shown are optional).
All input modules have universal opto-isolated control ports
so you can interface microphones, mic processors and source
machines in any combination you wish.

Individual plug-in
modules make
installation and
service a breeze.
Configuration is as
simple as setting the
front panel dipswitches
concealed under the
hinged meterbridge.
Digital and analog input channel daughtercards make field
conversions simple and fast. Easy access logic programming
dipswitches make configuration changes a snap.
Best of all, the D-75 is designed by the Wheatstone engineering
team so you know its construction quality and performance
are superior.
Audioarts didn’t stop with a standalone console. We also offer
the D-75N which allows you to tap into the powerful world of
networked audio. (see page 8).

Wheatstone D-75N
NETWORKABLE DIGITAL AUDIO CONSOLE
More and more radio stations are utilizing organization-wide networking to
enable sharing of programming and production resources. Nobody does
networking as well as Wheatstone. The D-75N is an enhanced version of
Audioarts’ established D-75 digital audio console that permits integration
with Wheatstone’s S-8 and S-16 Switches, as well as Wheatstone’s E-SAT
I/O Cage for networking. It allows the D-75 (normally a standalone audio
console) to access a digital audio network system on six of its input faders
(other inputs continue to operate independently) thus providing considerable
networked flexibility to an individual studio - the best of both worlds!
Where standalone input channels have A/B dual source select switches,
networked inputs have eight character SOURCE displays, SOURCE SELECT
encoder knobs and TAKE buttons which allow selection of any source made
available to the D-75N console via its CAT-5 network connector cable.
In addition, the six router channels (collectively called the NET-75 panel) allow
two local stereo analog sources to be made available to the network system.
Two additional connectors make two networked router sources available to
the console’s standalone input channels. At the same time the D-75N’s four
output busses (Program, Audition, Auxiliary and Utility) are made
available to the main router system through the console’s network
CAT-5 link. If an optional phone module is present, caller input
and feed mixes are also sent to the router system.
As with the D-75, the D-75N is also available in two
mainframe sizes: small (six hardwired plus six
networked input channels) and large (fourteen hardwired plus six networked input channels). Both
versions can be outfitted with an optional
two-caller phone module.
Both mainframes come standard with
two dual-mode LED VU meter pairs
(PROGRAM and SWITCHED),
clock and timer and a built-in
cue speaker. Optional line
select modules and tape
remote panels are also
available.

NETWORKABLE DIGITAL AUDIO CONSOLE
ADMINISTRATION AND CONTROLLERS
The Audioarts Network System is configured and administrated through
Wheatstone’s X-Point graphic user interface (right). X-Point software permits
easy access and set-up of source/destination crosspoints throughout your
facility from one central point. All control is password protected with three
levels of user access to safeguard the security of the system.
The Administrative Level allows complete access and control of all sources
and destinations throughout your complex, including hardware configuration,
signal naming, I/O (source/destination) crosspoint switching and destination
locking. The two lower level access modes are GUEST, which allows the user
to view crosspoint status but does not permit any switching changes, and
XYC GUI, which allows the logged in user to select crosspoints only. Signal
visibility for lower level access is set by the Administrator.
While you can control the system right from your desktop, it is often desirable
to have simpler additional hardware controllers, such as the Ethernet XY or
Hotbutton controllers pictured below, located throughout your facility.
Ethernet Rackmount XY Controller
Ethernet Hot Button Controller

X-Y CONTROLLER
This onscreen software module
emulates a rackmounted X-Y
router controller, selecting pulldown sources and destinations
based on signals available at the central digital audio router.
Signal visibility is programmed via password-protected
administrator level access.

SYSTEM SETUP IS EASY
D-75N Consoles have all inputs and outputs for your studio built right in.
Each console then simply plugs into the Wheatstone Router located in your
engineering room. E-SATs provide input, output and logic cards for use with
shared sources and destinations in your engineering room. Note the E-SAT
could alternately be located right in the studio to provide even more I/O at the
studio location. Simply plug the D-75N console into the E-SAT and the E-SAT
into a WheatNet S-8 or S-16 Switch.
WHEATSTONE E-SAT I/O CENTER
The Wheatstone E-SAT I/O cage acts as a
networked intermediate link between a D-75N
digital audio console and the central NET router.
It may be located in your TOC or in the local
studio. The E-SAT accepts local hardwired
digital and/or analog input signals and outputs
them in both analog and digital formats, where
they can be shared with a connected D-75N
console and/or NET router. Each unit can handle
up to 16 two-channel inputs (32 signals) and 16
two-channel outputs (32 signals), has two logic
cards with twelve bi-directional ports each, and
an audio transport card with two CAT-5 jacks.
The E-SAT chassis rear accepts plug-in card
modules for a clean and easy wiring installation.
Each unit accepts four input and four output
cards (analog or AES digital) and each card can
handle four stereo signals. Two I/O modules are
supplied for logic ports, and dual CAT-5 jacks
handle network connections (i.e., between a
D-75N console and a NET central router).
A short-loaded version is available for
smaller installations.
WHEATSTONE WHEATNET SWITCHES (S-8 or S-16)
Wheatstone’s WheatNet switches are high speed central switches that link
multiple studios with your technical operations center. Available in eight
(S-8) or 16 (S-16) port versions, each of its links can handle 64 secure
bi-directional data paths with embedded control signals, allowing you to
centralize shared audio resources and wiring in your TOC and seamlessly
integrate separate D-75N digital audio consoles as a working network,
with each console’s studio location handling both networked signals as
well as hardwired local sources.
WheatNet Switches operate autonomously with no external PC required
other than for initial setup and source naming. Once configured the PC
can be disconnected and the system runs standalone. Installation is
simple and quick (CAT-5 cables interconnect your studios), making
expansion easy. The switches are capable of 44.1 kHz, 48 kHz or
external sync operation.
Wheatstone WheatNet S-8 Switch Front Panel
Wheatstone WheatNet S-8 Switch Rear Panel
Installation and hookup is simple via the WheatNet switch’s rear panel.
CAT-5 interconnects are supported; each one connects a D-75N console
(or its associated E-SAT). An Ethernet link handles administrative tasks,
and a CLOCK port allows synchronization to an external master clock.
