Wiring Considerations

Vienna is designed for reliability, high performance and built to the highest
standards. Whilst great care has been taken to ensure that installations are made as
trouble-free as possible, care taken at this stage, followed by correct setting up will
be rewarded by a long life and reliable operation.
Before switching on your Vienna console, check that the mains
voltage selectors on the power supply units are set to the correct
mains voltage for your area, and that the fuses are of the correct
rating. This is clearly marked on the case of the power supplies. Do
not replace the fuses with any other type, as this could become a
safety hazard and will void the warranty.
Always ensure that you use the correct power supplies for your console. One
CPS550 or CPS550-B unit and one CPS650 or CPS650-B unit are required for the
16, 24 and 32 channel consoles, while the 40 channel console requires one CPS550
or CPS550-B and one CPS750 or CPS750-B. Different configurations of power
socket are used for each supply to prevent incorrect connection.
A For optimum performance it is essential for the earthing system to be clean and
noise-free, as all signals are referenced to this earth. A central point should be
decided on for the main earth point, and all earths should be `star-fed' from this
point. It is recommended that an individual earth wire be run from each electrical
outlet, back to the system star point to provide a safety earth reference for each piece
of equipment.
B Install separate mains outlets for the audio equipment, and feed these
independently from any other equipment.
C Avoid locating mains distribution boxes near audio equipment, especially tape
recorders, which are very sensitive to electro- magnetic fields.
D Where possible ensure that all audio cable screens and signal earths are
connected to ground only at their source.
