Caution! If you see any Channel LED Indicator blinking red, please disconnect the amplifier from the AC mains immediately and check that all external connections are cleanly made and secure. If the AC mains are not easily accessible, you can press and hold the Standby button for three seconds to reset the amplifier. If no fault is immediately obvious, please call your authorized Classe dealer for assistance. 4 Mode button The Mode button is used (along with the Select button) when configuring the amplifier for either balanced or single-ended operation. It is also used when configuring the turn-on delay and amplifier number of the amplifier when it is connected to a Classe preamplifier by the CAN Bus communications or Trigger systems. ........................................................................................................................................................ Rear PanelThe 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) InputBalanced audio interconnections were originally developed 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 consumer companies like Classe to preserve every nuance of the finest audio performances 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, 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.

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 Classe 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 Classe power amplifier with a Classe 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. 2 Single-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. Classe 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 Classe power amplifier, you need to eng...
