    Begin by unpacking and locating these items. Do not connect the A-7000 console to its power supply (and do not connect the power supply to the AC power line) until instructed to do...

  • Page 13: 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 A-7000 mainframe are con- nected together at the console, but are NOT connected to electrical ground and the chassis of the power supply. Safety requirements dictate that a positive connection from the console mainframe to electrical ground be made in the completed installation.

  • Page 14: Power Supplies

    Once the system is properly grounded, proceed with the console power supply installation and connection (next section). Power Supplies The A-7000 console is powered by a Wheatstone Model PSC-6008 If failsafe redundant sup- rackmount power supply. This heavy duty unit occupies five 19” wide rack...

  • Page 15: The Psc-6008 Power Supply

    Note that while the AC power cord ground wire terminates at the power supply chassis, it does NOT connect to the A-7000 console common; the console itself must be grounded separately. (See previous section,"System Ground".)

  • Page 16: Failsafe Dual Redundant Supply

    BOTH rackmount supplies powered up and connected to their associated equipment. Energizing Assuming the A-7000 console mainframe is properly placed and grounded, and its PSC-6008 power supply (or supplies) correctly rackmounted and connected to the console, you may now energize the PSC-6008 rackmount power supply by plugging it into the AC mains and turning it on, using its front panel circuit breaker/switch.

    I N S T A L L A T I O N a n d P O W E R Audio and Control Wiring All audio and control I/O connections to the A-7000 console are made through multipin connectors (DB-25 and DB-9) located on the bottom of the console mainframe.

  • Page 18: Connection Procedures

    If the machine has a -10 dBu output, don’t hesitate to turn module input gain as high as is needed. OUTPUTS — A-7000 consoles use a balanced output circuit which behaves exactly like the secondary of a high-quality transformer, with no center tap—this output is both balanced and floating.
