Opera Audio M10S Manual 

ensure that you read this manual in its entirety before attempting to operate the equipment. Please retain this manual for future reference. TO PREVENT THE RISK OF ELECTRIC SHOCK, DO NOT UNDER ANY CIRCUMSTANCES REMOVE ANY PARTS OF THE EQUIPMENT COVER. THERE ARE NO USER SERVICEABLE PARTS INSIDE. ALL SERVICING MUST BE CARRIED OUT BY QUALIFIED SERVICE PERSONNEL. WARNINGS Power Source The equipment should be connected to a power supply only of the type described in this manual or as marked on the equipment. Do Not Disassemble Do not attempt to service the equipment beyond that described in this manual. Touching the equipment’s internal parts could result in severe personal injury. All other servicing or problems as listed below should be referred to qualified Consonance service technicians: • The power supply cord or plug has been damaged • Objects have fallen or liquid has been spilled into the equipment • The equipment does not appear to function normally or exhibits a marked change in performance • The equipment has been dropped or the enclosure damaged Do not under any circumstances allow anyone to modify your Consonance equipment without first checking with Opera Audio, your dealer, or your distributor. Unauthorized modifications will invalidate your guarantee. This icon marks a presence of un-insulated “dangerous voltage” within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. This icon marks important operating, maintenance and service information that should be read to prevent possible personal injury Grounding or Polarization Power supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them, paying particular attention to cords and plugs, convenience receptacles, and the point where they exit from the amplifier.

an outside antenna is connected to the system, be sure the antenna is grounded so as to provide some protection against voltage surges and built up of static charges. Lighting Consonance hi-fi system can be damaged by lightning. Power amplifiers are particularly at risk and therefore should be turned off when there is risk of lightning strike. For complete protection all mains plugs and any aerial cables should be disconnected when not in use. Cleaning Never clean with furniture polish, benzene, or volatile liquids. Dust periodically with a clean, soft paint brush. Fingerprints can be removed with a moist polishing cloth. Speaker Impedance For best performance, the load presented by the speaker has to match the M10’s output impedance per channel. Refer to the speaker’s manufacturer handbook for information on the nominal impedance. The M10SE is factory set to match the speakers at 4~8 ohms. Ventilation The equipment should be situated so that its location or position does not interfere with its proper ventilation. 1. The equipment must not be placed on bed, sofa, or similar surfaces, that may block the ventilation openings, 2. The equipment must not be placed in a built-in installation, such as a bookcase or cabinet that may impede the flow of air. 3. The equipment should be situated away from heat sources such as radiators, heat register, stoves, or other electronic appliances that produce heat. This equipment is not intended for commercial use. Water and Moisture The equipment should not be used near water, e.g., near a bathtub, washbowl, kitchen sink, laundry tub, in a wet basement, or near a swimming pool etc. Similarly, do not placed objects filled with liquid, such as vases on top of the equipment.

welcomes you to the growing number of discerning audiophiles who own Opera Audio products. This manual has been prepared to help you to maximize your enjoyment of the performance and features of your new Consonance equipment. Please study this manual carefully and become acquainted with all the features, operation and capabilities of your new Consonance equipment. Should you have any questions, or desire information on other Opera Audio products, please contact your local Opera dealer. Unpacking & Set-up Unpacking Before any Opera Audio product leaves the factory it is carefully inspected for physical imperfections as a routine part of Opera Audio's stringent systematic quality control. After you have unpacked the equipment, carefully inspect for any physical damage. Save the shipping carton and packing materials as they are essential for future use to reduce the possibility of transportation damage. Set-up 1. Check Equipment Voltage Ensure that the operating voltage of the amplifier, check the shipping carton label and/or owners manual, conforms to the delivery voltage of your local power supply (i.e. 240V / 230V / 220V / 115V / 100V AC dependent on country). 2. Positioning the Equipment The amplifier may generate considerable heat during normal operation. Please ensure that the unit is far away from effect of any domestic heat source and adequate air circulation around the unit is provided to maintain cool operation. For air circulation, leave enough space around the unit (at least 3 cm on the top and 3 cm on the sides and leave enough space on the back for the power cord and interconnect cables). If the equipment is going to be mounted in an enclosed cabinet, it is recommended that the rear of the cabinet has vents to allow air to circulate around the unit. With these considerations implemented, the equipment should then provide exceptional performance as intended. However, the usual protection of equipment from excessive dust and moisture should always be observed. All the equipment made by Opera Audio has been carefully designed with high quality components so that Long-term undiminished performance is operated in accordance with the instructions provided. 3. Install Vacuum Tubes Locate the KT88, ECC82 and ECC83 vacuum tubes and insert them into their sockets according to the print on top lid. Pay attention on the proper tube orientation please and be sure to hold the tube by its base when inserting and

and the glass. 4. Connect Signal Cables Connect the input source to the amplifier’s right and left channel RCA jacks. Refer to rear chassis drawing for connection location. These jacks are labeled with colored washers: red for right and black for left. 5. Connect Speaker Cables Connect the speaker cables. Refer to rear chassis drawing for speaker connector location. Be sure the positive speaker lead is connected to the plus symbol on the speaker connector (In this case, red to red, black to black) Note: NEVER switch on the amplifier unless a speaker is connected to both output terminals. Operation of the amplifier without a load may damage the output transformers. Operating Tips A. Power cord, plugs and sockets The power cord should be routed so that it is not likely to be stepped on or pinched by items placed upon or against it. All the plugs and sockets supplied with your Consonance equipment have been chosen because they mark the best possible connection for their purpose. A poor contact will degrade the signal substantially, plugs and sockets should look clean and free from corrosion. The easiest way to clean them is to switch off the equipment, pull the plugs out of their sockets, and push them back in again. Special contact cleaners and contact enhancers should not be used as they tend to deposit a film, which is very difficult to remove and may degrade the sound. B. Switching on and off Source components and power supplies for CD players, tuners, preamplifiers and crossovers should be switched on before switching on the amplifier(s). Always switch the amplifier(s) off and wait about 5 minute for its power supply capacitors to discharge before connecting or disconnecting any leads. Always use the power switch on the equipment instead of the mains outlet switch. C. Running in Your Consonance equipment will take a considerable time to run-in before it performs at its best. The duration varies, but under some conditions you will find that the sound continues to improve for as much as five weeks. Better and more consistent performance will be achieved if the system is left switched on for long periods. However, please take note that all electronic equipment can be damaged by lightning and should not be left on for long periods unattended. D. Power supply Where fused plugs are used various amp fuses should be fitted. Fuses of a lower rating will fail after a period of use. A hi-fi system usually shares a main circuit with other household equipment some of which can cause distortion of the mains waveform. In some Consonance equipments such distortion can lead to a mechanical hum from the transformers. The hum is not transmitted through the
