[. . . ] Owner's Manual Omega Series Omega Monoblock WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS APPLIANCE TO RAIN OR MOISTURE. CAUTION RISK OF ELECTRIC SHOCK DO NOT OPEN CAUTION: TO REDUCE THE RISK OF ELECTRICAL SHOCK, DO NOT REMOVE COVER. REFER SERVICING TO QUALIFIED PERSONNEL. The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulated dangerous voltage within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock. The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance. Marking by the CE symbol (shown left) indicates compliance of this device with the EMC (Electromagnetic Compatibility) and LVD (Low Voltage Directive) standards of the European Community. NOTICE All of us at Classé take extreme care to ensure that your purchase will remain a prized investment. We are proud to inform you that all Classé components have been officially approved for the European Community (CE) mark under CE Certificate Number C401CLA1. MGS granted on 18 July 1996. This means that your Classé product was subjected to the most rigorous manufacturing and safety tests in the world. [. . . ] indicator The amplifier state is indicated by the indicator on the front panel. This light, in the shape of the Greek letter , indicates the operating state during normal operation, as follows: · dark = standby · blue (slow blink) = initialization/mute · blue (continuous) = operate Various fault conditions are indicated as follows: · red/blue · red (slow blink) · red (fast blink) Caution!= line voltage out of range = protection mode (DC, current or temp. ) = internal communication error 2 If the indicator is blinking red, please disconnect the amplifier from the AC mains immediately and check that all external connections are cleanly made and secure. If no fault is immediately obvious, please call your authorized Classé dealer for assistance. When in standby, the amplifier's gain stages are powered down. Only a small power supply and control circuit remain on, consuming relatively little power. Fortunately, since the output stages by their nature conduct a great deal of current, they warm up and sound their best very quickly. If you are not going to use the amplifier for an extended period of time, perhaps while traveling for a vacation, we suggest you disconnect it from the AC mains. Please be certain that the amplifier is in standby prior to disconnecting it from the AC mains. It is a good practice to disconnect any and all valuable electronics from the AC mains during electrical storms, as a lightning strike anywhere near your home can put a tremendous surge on the AC mains that will easily jump across a simple power switch. 15 Rear Panel 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. 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 applications). BAL Button The BAL button is used to configure the amplifier for balanced operation. It is also used when configuring the turn-on delay and sequence number of the amplifier (for future Classé CAN Bus applications). 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 extremely small microphone-level signals. For many years now, they have also been used by performance-oriented consumer companies like Classé to preserve every nuance of the finest audio performances 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 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 interconnection between your Classé components wherever possible. 16 2 3 ab c d e f g h ji k l 17 The pin assignments of this XLR input connector are: PUSH 21 3 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 standards adopted by the Audio Engineering Society. If you are using your Classé amplifier with a Classé preamplifier, you're all set. [. . . ] · Run through the troubleshooting sequence outlined above (assuming the amplifier is going into its protection mode). There is a specific troubleshooting procedure for a blown AC mains fuse, since this rare occurrence sometimes indicates a significant problem. Disconnect your amplifier from the AC mains, as well as from its input connections and speaker connections. If the fuse appears to be blown, replace it only with a fuse of the same type and rating (specified below). [. . . ]
