Rejection of common mode noise and distortion is achieved in the final,
current gain stage.
1.5 Use of Adaptors
Your Spirito preamplifier uses state of the art balanced circuit topology.
When using an adaptor to go from the Spirito balanced output to an
unbalanced input, pin 1 and pin 3 must be connected together. Pin 2 is
the non-inverting output and pin 1 and 3 are ground. The same
configuration is true when connecting an unbalanced source to a Spirito
balanced input. The V20 Reference Input Card does provide one
unbalanced RCA input. Whenever possible use balanced connections to
the Spirito.
