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
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).
General Warnings
Every piece of Consonance equipment is designed to produce the finest sound quality that can be
achieved, by avoiding compromise wherever possible. This can lead to circumstances that may be
unfamiliar to the equipment owner. The material that follows contains advice specifically related to
Consonance equipment as well as more general warning about the use of domestic audio products.
Please read it carefully:
The transformers in Consonance amplifiers and power supplies may sometimes make a mechanical
noise caused by distortion of the mains waveform. Consonance transformers are large in size and have
heavy gauge secondary windings making them relatively sensitive to such distortion. A separate mains
circuit for your hi-fi system may reduce the effect while also giving an overall improvement in sound
quality. It may be necessary however to take account of mechanical transformer noise when placing your
equipment.
In some circumstances, depending on where you live and the grounding arrangements in your home, you
may experience radio frequency interference. Controls on broadcasting in some territories allow very high
levels of radio frequency radiation and both the choice and exact placement of equipment may be critical.
If there is a known problem in your locality it is advisable to arrange for a home demonstration before
purchase to ensure that your selected Consonance equipment can be operated normally. Susceptibility
to radio frequency interference is related to the wide internal bandwidth necessary for high sound quality.
Systems incorporating moving coil phono preamplifiers and active crossovers are more likely to suffer.
Troubleshooting Guide
Equipment problem could also be caused by fault in any part of the system or its installation. As Legal
consumer protection varies from country to country, you should always first consult the local dealer for
any technical problems that you may experience. Please contact your local distributor or Opera Audio at
the address in the back of this manual for any difficulties that cannot be resolved.
Certain Consonance equipment is made in special versions for different territories as a result it is
impracticable to arrange international guarantees. Please establish appropriate guarantee arrangements
