Canvas

=Description/Objective=

+

The Biamp Canvas User Interface software will allow us to give our customers access to almost any parameters in the Tesira configuration. The use case that IVS will almost always be looking at is a channel selector or microphone selector. In this section, there are 16 cameras, each with their own microphone, and an adjacent observation room with 2 OWISP speakers. The customer is also requesting a User Interface, with the ability to solo one mic at a time through their overhead speakers, mute all mics, and adjust the speaker levels. This 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=

+

==Connections==

+

# If we've completed our physical connections, open the Tesira software and start building a configuration. 

+

# 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

+

#* Source Selector with 16 channels

+

# Something to note: The Channel Selector Block doesn't break apart in the Canvas UI software, which means the buttons would only be available vertically in a straight line. If it is crucial to rearrange the buttons in the UI, add the following blocks: 

+

#* 16-channel Logic Meter

+

#* 2 Preset Buttons with 8 presets

+

#* Also make sure the Source Selector has logic enabled

+

#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. 

+

#* Place the Preset Block(s) in a convenient place for now. 

+

#* Send the output of the Source Selector to the second Level Block, then the level block to the final Peak Meter and the Output Block for the EX/IO Expander. 

+

#* Connect the logic output from the Source Selector to the Logic Meter. 

+

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

==Channel Selector Components==

+

[[File:Channel_Selector_Block_Combo_2.png]]

+

The Source Selector, Logic Meter, Preset Buttons, and Level Block will all act together to build the User Interface in Canvas. 

+

[[File:Channel_Selector_Source_Block.png]]

+

# The Source Selector will determine what audio is sent to the outputs. It will also drive the Logic Meter. It will only live in the Tesira configuration. 

+

# The Logic Meter will light up according to the active channel on the source selector. The LEDs in the Logic Meter will become our indicators in the Canvas UI. 

+

# The Preset Buttons will drive the Source Selector. The presets must be made for each button. The Preset Buttons will be what the customer uses in the Canvas UI. 

+

# The Level Block will be used in the Canvas UI to mute or unmute the audio, and control the output volume of the OWISP speakers.

+

==Creating Presets==

+

Once the configuration is built, the only thing left to do is to create presets. Open the Preset Manager on the left side. 

+

[[File:Presets.png]]

+

# Create 16 presets for the Source Selector; one for each channel. Name them in a convenient manner. 

+

# Assign each preset to the Preset Buttons.

+

==Creating a Canvas User Interface==

+

In another section, we will build the corresponding Canvas UI configuration for the Channel Selector. Click the image below:
