    Each TV-80 audio console is equipped with a CR-80 control room monitor module. The control room module allows the console operator to monitor the TV-80 console’s inputs and outputs by means of a monitor source select switchbank and the console’s SOLO/CUE system. It is also SOLO the module that houses the console’s on-air tally port.

    Studio Monitor Module STUDIO General HDPN TV-80 audio consoles can be equipped with one or more STUDIO SC-80 studio monitor modules. Each of these modules allows the console operator to send monitor versions of the TV-80 console’s outputs to a separate studio. Source selection is determined by a set of monitor source select switches that match those available on the console’s control room monitor module.

    The PWR-80 power interface module accepts power from the console’s (dual failsafe) rackmounted SPS-40 power supplies and feeds it to the TV-80 console. In the unlikely event of a power supply failure, the panel automatically switches over to the second redundant supply so the console continues uninterrupted operation.

    A P P E N D I C E S Appendix I TV-80 Console Internal Wiring Paths As previously stated, most mainframe positions on a TV-80 console have three active sections: the main module itself, an (optional) overbridge preselector panel, and an associated fader panel directly in line with and below the main module (the two being separated by the console’s alpha-numeric source display strip).
  • Page 98 Not all equipment used in stations is balanced, however, and the most cost-effective devices often don’t have +4 dBu output levels, either. Because of these realities, all Wheatstone consoles are designed to accept balanced or unbalanced sources with levels as low as -10 dBu.

    A P P E N D I C E S Testing a "Live" (Powered-Up) Console – Precautions (1) If a module must be removed, but remain connected while trouble- shooting (using the extender ribbons that come with the console), place a piece of cardboard or other non-conducting material across the console where the module will be placed.

    Other Details (1) In general, TV-80 consoles are rugged and user friendly. I/O connections can be unplugged or plugged in while powered up with no damage. Occasionally, this may cause a transient in the logic system that may be sufficient to affect a channel’s ON/OFF or CUE status, but...
