2 x 2 Configuration

Description/Objective

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

Physical Wiring/Line Diagram

Use inputs 1&2 and outputs 1&2 to keep things simple. When terminating the 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. 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 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 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 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 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:

Matrix Mixer

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.
