Classe CT-2300 Two-Channel 用户手册

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.

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 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.

Single-ended cables using RCA connectors are the most common form 

of analog connection used in consumer electronics. When implemented 

carefully and with use of high quality interconnecting cables, this standard 

can provide excellent performance. Classé has gone to extraordinary effort 

to ensure that the single-ended (RCA) input of your power amplifier is 

as good as possible. However, this connection standard cannot offer the 

immunity from interference that balanced interconnection does—hence 

our recommendation to use the balanced inputs when possible.

Two pairs of high quality five-way binding posts are provided on the 

amplifier, in order to facilitate bi-wiring. 

In practice, bi-wiring involves connecting two (preferably identical) sets 

of speaker cables between each amplifier channel and its corresponding 

loudspeaker. In many cases, the benefit is a subjectively improved level of 

clarity and detail from the speaker, as a result of being able to feed the two 

separate sections of its crossover and driver complement with identical, yet 

separate signals.
