    Product Description Introduction This section provides a general description of the serial digital version of the Performer™ 10 x 1 Routing Switcher. Included are Product features Functional description Specifications Product Features Performer is a serial digital, 10-input by 1-output, video with dual (AES/EBU) audio routing system from Grass Valley Group.
  • Page 22 Performer options include: Tally relays for 10 inputs & Joystick Override control Remote control panel Performer circuitry resides in a sealed, 1 rack unit frame. The standard unit contains just four printed circuit boards. These are: Rear Motherboard (two versions available)

  • Page 23: Functional Description

    Functional Description See descriptions and the block diagram on the following pages. System The PERFORMER Serial Digital Video and AES/EBU Digital Audio10X1 routing switcher. It is available in four (4) basic models (configured with either BNC or D type audio connectors and supplied with either local or remote control panel) as described below.
  • Page 24 • AUTO mode: provides automatic bit rate selection when input rates are different. The PERFORMER automatically detects the input bit rate and switches to the correct rate, i.e. with D1 at Input 1 and D2 at Input 2 user switches from Input 1 to Input 2. The switcher will automatically switch to the new rate.

  • Page 25: Rear Motherboard

    Functional Description Rear Motherboard All inputs and outputs are through connectors on the Rear Motherboard. This board has only mechanical functions and mounts no active circuitry. There are two different types of rear connector panels available (unbalanced BNC type audio connectors and balanced D type audio connctors).

    For ASCII and GVG Model 200 protocols, you will also set serial port data bits at 7 or 8. For other protocols, the data bits are automatically set at 8. Performer serial port stop bits are automatically set at 1.
  • Page 78 Use this protocol when you are controlling a TEN–XL switcher from a host computer using the TEN–XL’s modified SMPTE, and you wish to control the Performer as well. GVG Model 100 and 110 Use this protocol when you are controlling the Performer from the Grass Valley Model 100 or 110 Production Switcher.
