Figure 6: Spirito Reference Input Card Connectors
• Spirito will accept a signal from a source with balanced outputs via
a high quality XLR or Fischer connector. There are two sets of
balanced inputs on the Reference Input Card. Balanced input 1 has
a XLR and a Fischer connector. The connectors are in parallel so
use one or the other. Balanced input 2 is configured the same as
input 1. Input 3 is single ended for a connection to source
equipment that does not have balanced outputs.

input connector is.
