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
Two channels of the AMP5 support balanced interconnection. When
used in a 5.1 channel system, these are intended for use with the L & R
Front channel outputs of the Sigma series SSP or those of other preamp/
processors that are equipped with balanced outputs.
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 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.
