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 am-
plifier into your system.
1 SE Button
The SE button is used to configure the amplifier for single-ended
operation. It is also used when configuring the turn-on delay and
sequence number of the amplifier (for future Classé CAN Bus ap-
plications).
2 BAL Button
The BAL button is used to configure the amplifier for balanced op-
eration. It is also used when configuring the turn-on delay and se-
quence number of the amplifier (for future Classé CAN Bus appli-
cations).
3 Status LED indicators
There are two LED indicators located just below the SE and BAL
buttons, indicating the use of either the balanced (XLR) or the
single-ended (RCA) input connector.
These indicators are also used to indicate certain fault conditions
in your amplifier, should any ever arise.
4 Balanced (XLR) Input
Balanced audio interconnections were originally developed in the
professional audio world, for preserving the delicate nuances of ex-
tremely small microphone-level signals. For many years now, they
have also been used by performance-oriented consumer compa-
nies like Classé to preserve every nuance of the finest audio per-
formances in your collection.
Essentially, 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 ra-
tio by 6 dB; they also do an excellent job of rejecting noise and
interference that might otherwise be picked up between the com-
ponents, due to either EMI (electromagnetic interference) or RFI
(radio frequency interference). In the world of wireless telecom-
munications, 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 bal-
anced analog interconnection between your Classé components
wherever possible.
