1 Balanced (XLR) Input
Balanced audio interconnections were originally developed 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 fi nest audio performances in your collection.
Technically, balanced audio interconnections provide two distinct benefi ts:
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, due to either EMI (electromagnetic
interference) or RFI (radio frequency interference). In the world of wireless
telecommunications, there is more potential interference around than ever
before—it makes sense to keep it out of music and movie soundtracks.
For this reason, we strongly recommend using the balanced analog
interconnections between your Classé components wherever possible.
