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 2A3, 12BH7 and ECC82 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 removing. This will minimize the chance
of breaking the glue between the socket and the glass.
