Balanced (XLR) Input
Balanced audio interconnections were originally developed for the
telephone and more recently have been used in the professional audio
world for preserving the delicate nuances of extremely small microphone-
level signals. For many years now, they have also been used by
performance-oriented companies such as Classé to preserve every nuance
of the finest audio recordings in your collection.
Technically, balanced audio interconnections provide two distinct benefits:
they double the signal’s strength as it travels from one component to the
next, increasing the potential Signal-to-Noise ratio by 6 dB; they also do
an excellent job of rejecting noise and interference that might otherwise be
picked up between the components. If executed as in the Delta MONO
with a high degree of symmetry between the inverting and non-inverting
signal paths, balanced connections can offer the best performance.
For this reason, we strongly recommend using the balanced analog
interconnections between your Classé components wherever possible.
The pin assignments of these
XLR input connectors
are:
Pin 1: Signal ground
Pin 2: (non-inverting)
Pin 3: Signal – (inverting)
Connector ground lug: chassis ground
These pin assignments are consistent with the standard adopted by the
Audio Engineering Society (AES14-1992).
