Description/Objective

In this example, we will be building 2 sim rooms and 2 observation rooms with windows and live audio. We will have 2 microphones, 2 cameras, and 2 PSP speakers (and/or SHM-1 headphone amps).

Physical Wiring/Line Diagram

2 inputs and 4 outputs will be needed. Use input 1, and outputs 1&2 for the first pair of sim room and observation room; and input 2 and outputs 3&4 for the second pair. When terminating the cables, the mics will go into Orange Inputs; audio lines to the cameras will go into Black Outputs 1&3; audio lines to speakers into Black outputs 2&4.

Tesira Software

Connections

  1. If the physical connections are complete, open the Tesira software and start building a configuration.
  2. In this configuration use the following blocks:
    • TesiraFORTE CI block
    • Peak Meter x 2
    • Uber Filter x 2
    • Matrix Mixer with at least 2 inputs and 4 outputs, with one extra output
  3. Connect the blocks as follows:
    • The Tesira Input block will already be connected to the AEC block, so connect the first peak meter to the Input block also. This will help ensure proper levels are set on the preamp.
    • Connect the AEC block channels 1&2 to the Uber Filters.
    • Send the Uber Filters to the Matrix Mixer.
    • Connect output 1-4 from the mixer to port 1-4 on the Tesira Output block AND to the second peak meter. This will ensure the right audio levels are sent to the camera.
    • Connect the extra output from the Matrix Mixer to the AEC reference. The Automatic Echo Cancellation feature will not be used in this example. However, the AEC reference block cannot be deleted from the configuration. It also will not compile the configuration if any blocks are not connected (including the AEC reference block.) So use the extra output from the mixer as a "dummy output" channel. Do not send any audio to this channel.


When this is complete, the file should look something like this:
