Description/Objective

In this example, we will be connecting two microphones to two cameras in one room.

Physical Wiring/Line Diagram

Again, we can use whichever inputs and outputs we’d like, so let’s use inputs 1&2 and outputs 1&2 to keep things simple. When we terminate our cables, the mics will go into Orange Inputs 1&2 and the audio line to the cameras will go into Black Outputs 1&2.

Tesira Software

Connections

  1. Once we've completed our physical connections, open the Tesira software and start building a configuration.
  2. In this configuration we'll be using the following blocks. Add these blocks to the configuration:
    • TesiraFORTE CI block
    • Peak Meter x 3
    • Uber Filter x 2
    • Level Block with 2 channels
    • Compressor with 2 channels, "ganged mode" and "advanced curve"
    • Matrix Mixer with at least 2 inputs and 2 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 us to be sure we have the proper levels set on the preamp.
    • Connect the AEC block channels 1&2 to the Uber Filters.
    • Send the Uber Filters to the Level Block.
    • Send the Level Block to the Compressor and the second peak meter.
    • Send the Compressor to the Matrix Mixer.
    • Connect output 1&2 from the mixer to port 1&2 on the Tesira Output block AND to the third peak meter. This way we can make sure to reach the right audio levels before we send it to the cameras.
    • Connect the extra output from the Matrix Mixer to the AEC reference. We will not need to activate the Automatic Echo Cancellation feature in this example. However, Tesira will not allow us to delete the AEC reference block for some reason. It also will not compile the configuration if any blocks are not connected (including the AEC reference block.) So, I’d recommend using an extra output from the mixer as a "dummy output" channel. We will not send any audio to this channel.


When we're complete, our file should look something like this:

  1. The only difference between this configuration and the last, Simple Configuration with EQ and Compression, is the use of 2 input and 2 output channels.
  2. Mixer: In this example, both mics and both cameras live in the same room, so both mics are sent to both cameras.
