[. . . ] The 48 output devices are divided evenly, 24 being utilized to maintain rail voltage, and the other 24 utilized as output power devices. The result of this unique design is an amplifier which offers uncompromised performance even under the most adverse conditions. 6 Unpacking and Positioning Unpack your Omicron Monaural Power Amplifier carefully. If you notice any shipping damage, contact your dealer immediately. Saving the packaging material is advised in case the unit needs to be shipped for service. Contents Included in the case should be the following items: 1. This manual If any of these items are missing, contact your dealer immediately. 7 Positioning the Omicron Monaural Power Amplifier For best performance, place your Omicron Monaural Power Amplifier on a solid, non-resonant surface. Do not place the Omicron Monaural Power Amplifier directly on top of another component. Place the Omicron Monaural Power Amplifier near its final set-up position, allowing 8 inches of clearance at the rear for tightening the speaker output connectors. The power transformer in the Omicron Monaural Power Amplifier is located at the bottom of the chassis and just behind the front plate. Ideally a few feet should separate this area from any components which are susceptible to hum. These include preamplifiers, turntables and interconnect cables. Allow 6 inches above and on each side of the unit to provide adequate cooling. 8 Connections Pictured here is the rear of the Omicron Monaural Power Amplifier showing all input and output connections. Refer to the page number indicated for more information on these connections. Analog Inputs Speaker Outputs IR IN & OUT AC Power Input 9 AC power Check that the AC voltage for which this unit is configured matches your local AC line voltage. The correct operating voltage is indicated on the rear of the chassis, adjacent to the AC power inlet. Operating this unit on AC voltage other than that specified on the rear of the unit can damage or destroy this unit and increase the risk of electric shock. Connect the AC power cord to the rear of the unit and directly to an AC outlet. For best results, do not use extension cords or multipleoutlet "power strips". Also, do not disable the ground pin as this can increase the risk of electric shock. Pictured below is the wall plug of the Omicron Monaural Power Amplifier showing the live and neutral pins. For optimum performance make sure the pins maintain proper polarity. Live Pin Neutral Pin 10 Analog inputs The Omicron Monaural Power Amplifier has both balanced (XLR) and single-ended (RCA) inputs. Both types of inputs have been carefully optimized to give the best possible performance. However, the most realistic and natural sonic quality is obtained by using the balanced inputs on your amplifier. The balanced (XLR) and single-ended (RCA) inputs must be used separately. Ensure that your new Omicron Monaural Power Amplifier is OFF before changing any connections. When the amplifier is shipped from Classé there is a jumper between pins 1 and 3 of the balanced (XLR) inputs. To use your amplifier in single-ended mode simply connect the single-ended interconnects from the preamplifier to the RCA inputs of your Omicron Monaural Power Amplifier. [. . . ] The Omicron Monaural Power Amplifier also has a protection circuit designed to detect unusual distortion and DC content at the amplifiers output. 13 Protection mode continued When the Omicron Monaural Power Amplifiers protection circuitry is triggered the unit will enter the protection mode. The Omega LED indicator on the amplifier front panel will FLASH red. Power OFF the amplifier by unplugging the unit. Please note that once your Omicron Monaural Power Amplifier enters the protection mode the Power Switch will not function. [. . . ]
