The following descriptions are intended as a quick reference, should you have
any questions about your new product. Please see the next section (entitled
Initial Setup) for specific advice on incorporating your new amplifier into your
system.
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 consumer companies like Classé to preserve
every nuance of the finest audio performances 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, 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.
