1 THANK YOU FROM EVERYONE AT CLASSÉ Thank you for purchasing the Classé OMEGA SERIES PRE-AMPLIFIER. We take great pride in offering components that combine exceptional sonic performance and long-term reliability. To do that, we have invested in extraordinary design and manufacturing facilities. We trust that you will enjoy your purchase for many years to come. CLASSÉ DESIGN PHILOSOPHY All of our components benefit from the same rigorous design goal: All Classé products must reproduce music with the harmonic and spatial integrity typical of fine instruments heard in a live, unamplified performance. Single Circuit Design To this end, we make extensive use of carefully optimized versions of the same basic circuit precisely matched to specific power requirements. This means that all Classé line level components and power amplifiers benefit from years of refinement. However, our efforts do not stop here. Listening: The Critical Design Element Once we determine general circuit values for a particular application, we listen carefully while exchanging and mixing different parts (transistors, capacitors, wiring, PC boards, etc.) and adjusting specific operating voltages within proper engineering ranges. Extended Real-World Lifespan Every Classé component, even the most affordable, benefits from our painstaking approach to design parameters. The result is an optimum balance between the often-conflicting demands of exceptional performance and long- term reliability. Our most expensive components gain from even tighter tolerance parts and highly segmented and exceptionally robust power supplies with large reserve-current capabilities. Our Pride in Manufacturing, Your Pride in Ownership We build all of our components to the highest possible standards. From multi-layer glass-epoxy circuit boards, the full sized power-supplies, and the massive faceplates, every Classé product is a tribute to both the science and art of sound reproduction. We hope that you derive as much pleasure and satisfaction in using your Classé as we did in producing it. UNPACKING & SET-UP Your CLASSÉ OMEGA SERIES PRE-AMPLIFIER has been packed and shipped as two separate units: the power supply and the pre-amplifier itself. Each has been carefully wrapped in heavy gauge plastic, packed in semi-rigid foam and contained in a special box. To remove the units, open and spread the top flaps of the boxes. By their sides, lift out each entire unit with foam pieces intact. Remove each foam side by pulling straight out. Remove the plastic wrap and inspect each unit for any concealed damage. Apart from this owner's manual, please ensure the following has also been included: - DETACHABLE AC LINE CORD - DETACHABLE DC POWER SUPPLY CABLE ASSEMBLY - ALLEN KEY FOR TOP COVERS - REMOTE CONTROL UNIT (Batteries: AAA x 2 included). Please report any damage or missing parts to your dealer promptly. This PRE-AMPLIFIER, being capable of very high gain, must be located in a position free of any hum-inducing magnetic fields. (This also applies to turntables and interconnect cables.) Positions adjacent to power amplifiers, A.C line filters, or regulation devices should be avoided. Ideally, a few feet should separate the PRE-AMPLIFIER from the power amplifier. As well, keep low-level interconnect cables away from the power amp and separate from AC line cords. Keep the DC cable assembly separate from the AC line cord and separate from the input and output interconnects as well. Heat generated by the PRE-AMPLIFIER is negligible. Air space around the unit need not be a concern. Check the Serial Number sticker on the back of the unit for the correct operating voltage. Regardless of voltage, the internal fuse rating should be 4 AMP SLO-BLO. CONNECTING POWER SUPPLY AND SETUP Select the spot you wish to put the new OMEGA SERIES PRE-AMPLIFIER. Place the POWER SUPPLY unit there. If you wish to have the two pieces sit side by side make sure there is enough room, and also make sure there is enough room for them to be stacked if this is the preferred configuration. Connect the DC POWER SUPPLY CABLE to the Power Supply Connector on the rear of the Power Supply module. Do not attempt to over-tighten the capture nut. Next connect the other end of the DC POWER SUPPLY CABLE to the Pre-amplifier module. Do not attempt to over-tighten the capture nut. (The two ends of the DC POWER SUPPLY CABLE are the same; either end may be attached to either module.)Attach the various input and output cables to the pre-amplifier module. Where possible use balanced interconnects. Do not attach the AC line cord until all interconnects have been installed. AC LINE POWER The Classé OMEGA SERIES PRE-AMPLIFIER self- contained POWER SUPPLY has a POWER SWITCH located on the left lower corner of the faceplate, beneath the LED, which permits you to turn on (see SAFETY FEATURE below) or shut the unit down completely. When power is ON the LED glows red, and when power is OFF the LED is out. The separate Classé OMEGA SERIES PRE- AMPLIFIER unit also has a STANDBY BUTTON located on the lower left corner s of its front panel which permits you to partially shut down the unit while keeping important parts of the circuitry warmed up. While thoroughly musical shortly after initial turn-on, the PRE-AMPLIFIER will exhibit sonic growth during its first 300 hours of use. Safety Feature The OMEGA SERIES PRE-AMPLIFIER is designed with an auto-muting circuit which engages during the initial 7 seconds count down and is indicated by the flashing GREEN STANDBY LED when the unit is first powered up, or after an AC power failure if the power switch was on. After the 7 seconds countdown, the STANDBY LED to the left of the front panel will be GREEN thus showing that the unit is in STANDBY mode. This feature will prevent any turn-on surges or unstable output from reaching the power amplifier and possibly the loudspeakers. Similarly, make sure the STANDBY is ON (SHOWING GREEN) and then turn the POWER SWITCH OFF when removing A.C. line power. CAUTION: DISCONNECT AC LINE CABLE WHILE MAKING ALL CONNECTIONS. FLOATING THE GROUND, OR DEFEATING THE GROUND ON A 3-PRONG LINECORD MAY CREATE A SHOCK HAZARD. CONNECT ALL INTERCON-NECT CABLES BETWEEN THE ELECTRONICS BEFORE CONNECTING THE A.C LINECORDS TO THE WALL OUTLETS. THIS WILL REDUCE THE POTENTIAL SHOCK HAZARD. SEE ALSO THE WARRANTY SECTION OF THIS OWNERS MANUAL. INPUTS The input jacks are clearly marked on the back of the OMEGA SERIES PRE-AMPLIFIER. The following inputs are provided: LINE 1, LINE 2, LINE 3, BAL 1, BAL 2, BAL 3, LINE-SSP and BAL-SSP. LINE LEVEL INPUTS: LINE 1, LINE 2, and LINE 3: These are all high level inputs sharing exactly the same characteristics, and may be interchanged if so desired. BALANCED INPUT BAL 1, BAL 2, and BAL 3: The XLR BALANCED INPUTS are true differential high level inputs, wired as follows:
