  • Page 12: System Ground

    The first step is to ground the console. Note that as supplied from the factory, console rackmount power supply common, audio ground, and the W-12 mainframe are connected together at the console, but are NOT connected to electrical ground and the chassis of the power supply.

  • Page 13: Further Grounding Details

    10-32 screws and insulating washers between rails and faceplates. Once the system is properly grounded, proceed with the console power supply installation and connection (next section). page 1 – 4 W-12 / Sep 2007...

  • Page 14: Power Supply

    Rear view of the SPS-100 rackmount power supply The W-12 console is powered by an Audioarts Model SPS-100 rackmount power supply. This unit occupies two 19” wide rack spaces (total height 3-1/2”). Convection cooled, it requires ample ventilation space above and below it.

  • Page 15: Energizing

    Audio and Control Wiring Audio I/O and control connections to the W-12 console are made via DB-25, and DB-9 connectors, and 6-pin and 3-pin plug terminals, located on the rear panel of the console. See the console’s rear drawing on page 1-8.

  • Page 16: Unbalanced Connections (Analog Audio)

    At the unbalanced source machine’s output, connect the black wire (LO) to the shield. ANALOG OUTPUTS — All of the W-12 console’s line level analog outputs are electronically balanced, low impedance, outputs, expecting a minimum load of 600 ohms. The outputs are balanced but are not floating.
