Connecting Audio Inputs and<br />

Outputs to the <strong>Huron</strong><br />

Audio inputs and outputs are connected to the <strong>Huron</strong> system via<br />

1U 19” rack-mount patch panels or ADAT optical connectors<br />

located on the <strong>Huron</strong> ADAT I/O card.<br />

Each patch panel is wired with 16 XLR connectors and one D62<br />

male connector. The gender of the XLR connectors used is<br />

tailored to the configuration of the I/O card with which the<br />

panel is intended to mate. Male connectors are used for outputs<br />

and female connectors are used for inputs. A typical example is<br />

shown in Figure 7. This panel is to mate with an I/O card with<br />

1-4 output modules and 1-4 input modules.<br />

Each IO module in the <strong>Huron</strong> will consume 2 input or output<br />

points on the patch panel regardless of whether they are<br />

analogue or digital.<br />

An analogue IO will output or take as input both left and right<br />

channels through two points on the connector panel, requiring<br />

two XLR connectors. For the example below these are<br />

represented by output points 1 and 2 and input points 13 and 14.<br />

A digital IO will output or take inputs for both the left and right<br />

channels though a single point on the connector panel, requiring<br />

only a single XLR connection. The input or output to the<br />

digital IO should be on the odd numbered connector. In the<br />

example below this is represented by the digital input 15 (the<br />

number 16 point is skipped or ignored).<br />
