  • Page 10: Unpacking The Console

    The console extends approximately 6” above the countertop at the meterbridge. Do not connect the ALM-12d console to its power supply (and do not connect the power supply to the AC power line) until instructed to do so.

  • Page 11: 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 ALM-12d mainframe are connected 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 12: Power Supply

    Once the system is properly grounded, proceed with the console power supply installation and connection (next section). Power Supplies The ALM-12d console is powered by a Wheatstone Model PSC-D340 If failsafe redundant sup- rackmount power supply. This heavy duty unit occupies three 19” wide...

    Audio and Control Wiring All audio and control I/O connections to the ALM-12d console are made through multipin DB-25 connectors located on the rear panel of the console. The factory supplied hand crimping tool is used for all I/O wiring connections to and from the console (see instruction on the page 1-9).

  • Page 16: Connection Procedures

    “consumer” digital audio interface is a two wire unbalanced signal typically on a single RCA style connector. To connect SPDIF devices to the ALM-12d console simply wire the SPDIF center conductor (HOT) to the digital input HI pin and SPDIF shell (ground) to the LO pin. Connect the digital input SH at the console end only.

    Audio signals come in several flavors. They can be mono or stereo, mic level or line level, analog or digital. The ALM-12d is designed to handle up to eight analog stereo line level inputs. Two other stereo line inputs can be used for stereo signals or can be split to provide four mono mic inputs (two each per stereo line input) instead.
