Single-Ended RCA Input, Speaker Outputs

ENGLISH

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, you’re all set – just take standard balanced interconnect cables and plug them in.Then engage that input on the power ampliﬁer by conﬁguring it as described in Initial Setup.

If you are using another brand of preampliﬁer, please refer to the operating manual of your balanced-output preampliﬁer to verify that the pin assignments of its output connectors correspond to your ampliﬁer. If not, have your dealer wire the cables so that the appropriate output pin connects to the equivalent input pin.

2Single-Ended (RCA) Input

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) inputs of your power ampliﬁer are 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.

If you elect to use the single-ended inputs of your Classé power ampliﬁer, you need to engage them by conﬁguring the ampliﬁer as described in Initial Setup.

3Speaker Outputs

A pair of high quality ﬁve-way binding posts is provided for each channel of the ampliﬁer.

Although the binding posts on your Classé ampliﬁer will accept bare wire connections, we strongly recommend the use of high quality spade or hook lugs, crimped and soldered onto the ends of your speaker wires. Using high quality connectors will ensure that your speaker connections do not gradually deteriorate from fraying and oxidizing bare wires. It also helps prevent accidental short-circuits from poorly-terminated connections.

CA-3200 specifications
