Wiring inputs and outputs in Tesira

With the many I/O options available to the Tesira family and the multitude of wiring formats and schemes used in the industry, it can be difficult to remember how to wire certain things for proper operation. This article shows the most typical wiring schemes used with BiampTesira hardware.

Always ensure that the Euroblock screw connectors are snugly tightened onto properly trimmed bare wire leads. Terminal screws should not be crimping down on the insulation as this will prevent a proper electrical connection with the bare wire. Trim any loose wire strands or re-terminate the wire to address them. Do not allow any stray wire strands to connect with a neighboring wires as this cause an electrical short between the wires. To avoid accidental shorts no bare wire should be left exposed outside of the Euroblock connector.

Inputs

Note: Input wiring schemes apply to both Mic/Line inputs and AEC inputs in servers and expander devices

Balanced Mic/Line Input

Unbalanced Line Input

Stereo Unbalanced Line Input

Note: For this wiring scheme, two input channels are required; one for the right channel signal and one for the left channel signal.

Outputs

Balanced Line Output

Unbalanced Line Output

For unbalanced connections the Biamp default output level of 24dBu may be too high. Lowering the output level in the Output block will allow you to avoid overdriving the input of the next device.

Unbalanced Line Out (2 channels) to "Stereo" TRS connection

For unbalanced connections the Biamp default output level of 24dBu may be too high. Lowering the output level in the Output block will allow you to avoid overdriving the input of the next device.

Connectors

Biamp products use 0.2" (5.08mm) pitch Phoenix or euro-block connections for most audio inputs and outputs.
