Connecting Aurora Sidecar To Power Source:
The sidecar uses an
external linear dc
power supply and the
correct input voltage
must be selected
before
connecting the power
supply to ac power.
The red input voltage selector should be positioned up (115v setting) for 100v – 120v ac
supplies and positioned down (230v setting) for 220v – 240v ac supplies.
It is very important to ensure the correct input voltage is selected. If 230v is applied
when the switch is selected to 115v, the primary windings of the transformer will be
damaged and the fuse will blow. Replacing the fuse will not repair the damaged
windings and the warranty on the power supply will be voided as there are warnings
printed on the front and reverse of the power supply case and emphasized here.
Linear power supplies use a large transformer that will radiate a small electro-magnetic
field outside the steel case. Always position the power supply away from any sensitive
audio transformers (that you might have in nearby microphone preamplifiers) and do not
put anything on top of the power supply that would prevent the heat from the internal
heatsink escaping.
Always use a 3 pin ac (IEC) cable and plug to provide the power supply with a safety
ground connection. Never use any form of ground lift.
The power supply has both input and output fuses to give maximum protection to both
the power supply and the sidecar. It would be very unusual for either the 24v or 48v
labeled fuses to blow and this would most likely be caused by a power cable being
crushed by a door or wheeling something very heavy over it. Always replace the fuse
with one of the same value, as printed below the fuse holder.
