6 7 8 More and more radio stations are utilizing organization-wide networking to Wheatstone D-75N enable sharing of programming and production resources. Nobody does NETWORKABLE DIGITAL AUDIO CONSOLE 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.

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.

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

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. Wheatstone WheatNet S-8 Switch Front Panel 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 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.
