Channel Selector Configuration

Description/Objective

In this example, there are 16 cameras, each with their own microphone, and an adjacent observation room with 2 OWISP speakers. The customer is also requesting the ability to choose one mic at a time through their overhead speakers, which means we will also build a Canvas User Interface (this will be covered in another section). Before building in Canvas, it is crucial to create the Tesira configuration properly.

Physical Wiring/Line Diagram

Below is the physical wiring diagram, which includes 2 Tesira Forte, a Remote Expander EX/IO, and an Extreme X440 AVB Switch.

Tesira Software

Additional Blocks

1. If 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:
   • TesiraFORTE CI block x 2
   • Output Block with 4 channels (the remote expander)
   • Peak Meter x 7
   • Uber Filter x 16
   • Level Block with 16 ports and another with 1 port
   • Compressor with "ganged mode" and "advanced curve"
   • Matrix Mixer with 16 inputs and 16 outputs, with one extra output
   • Channel Selector with 16 channels and logic enabled
   • 16-channel Logic Meter
   • 3 Preset Buttons - two with 8 and another with 1

1. Connect the blocks as follows:
   • Connect two peak meters to the Tesira Input blocks. This will help us to be sure we have the proper levels set on the preamp.
   • Connect the AEC block to the Uber Filters, then the Filters to the Level Block.
   • Connect the Level Block to the Compressor and two Peak Meters.
   • Connect the Compressor to the Matrix Mixer.
   • Connect the outputs from the mixer to the Output blocks, peak meters, AND the Channel Selector Block.
   • Connect the extra output from the Matrix Mixer to the AEC reference blocks. We will not need to activate the Automatic Echo Cancellation feature in this example.
   • Connect the logic output from the Channel Selector to the Logic Meter.
   • Place the Preset Blocks in a convenient place for now.
   • Send the output of the Channel Selector to the second Level Block, then the level block to the final Peak Meter and the Output Block for the EX/IO Expander.

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