If your preamplifier is equipped with a balanced main output, it's best
to wire the Nº23.5 for balanced operation, particularly if long lengths
of cable are required between the preamplifier and the Nº23.5. (See
Figure 3 for the pin assignments of the XLR-type inputs on the rear
panel of the Nº23.5.)
Connect the XLR-type male line-mount connector to your
preamplifier's main output cable according to Figure 3, carefully
observing pin assignments. (Refer to your preamplifier's operating
manual to verify that the pin assignments of its output correspond to
the diagram above. If they don't, wire the connector so that the
appropriate output pin connects to the equivalent input pin.)
When complete, connect the main outputs of the preamplifier to the
left- and right-channel XLR-type inputs on the rear panel of the Nº23.5.
Be sure to remove the shorting strap between Pins 1 and 3 before
inserting the output cable connectors.

inputs on the rear panel of the Nº23.5.
