Classe Audio CA-D200 Manual De Usuario

10

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.

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. 

 

The pin assignments of these XLR input connectors are:

  Pin 1: Signal ground

   

Pin 2: Signal + (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). 

If you are using your Classé power amplifier with a Classé preamplifier/

processor, you’re all set – just remove the supplied shorting pins (between

Pins 1 and 3) from the amplifier’s XLR connector(s), take standard

balanced interconnect cables and plug them in.

If you are using another brand of preamplifier or processor, please refer to its 

operating manual to verify that the pin assignments of its output connectors 

correspond to those of your amplifier. If not, have your dealer obtain cables 

with the appropriate output pin connecting to the equivalent input pin.
