Owner’s Manual
Precautions
Before installing, setting up or operating this equipment make sure you have read and
fully understand all of this section and the “IMPORTANT SAFETY INSTRUCTIONS” at the
front of this manual.
This equipment is supplied by a mains voltage that can cause electric shock injury!
The following must be observed in order to maintain safety and electromagnetic compatibility (EMC)
performance.
Safety warnings
Signal 0V is connected internally to the
chassis.
To completely isolate this equipment from
the AC mains, while observing full safety
precautions (see “Power” on page xiii),
switch off the isolator switch (above the
mains power sockets on rear of control
centre) and then switch off the mains at
the three mains outlets. Unplug the three
mains leads from the rear of the control
centre. For details of how to remove Volex
locking type plug, see “Power” below.
To avoid electrical shock do not remove
covers.
General precautions
In the event of ground loop problems,
disconnect the signal screen at one end of the
connecting cables. Note that this can only be
done when the equipment is used within a
balanced system.
Do not remove, hide or deface any warnings or
cautions.
Power
The system power supplies contain LETHAL
VOLTAGES greatly in excess of the mains
voltage and its rails can produce extremely large
currents that could burn out equipment and
wiring if shorted.
The internal power supplies are of the switch
mode type that automatically sense the
incoming mains voltage and will work where the
nominal voltage is in the range 100VAC to
240VAC.
Each mains inlet is to be sourced from its own
separate wall-mounted mains outlet socket.
Otherwise, their mains sources must be suitably
distributed so as to meet local safety
regulations.
A Volex locking type plug is fitted on each
supplied mains cable, which plugs into a mains
IEC connector on the unit. When fitted properly
the Volex plug locks into place, preventing it
from working loose, or being inadvertently
knocked loose or pulled out. To fit a Volex plug,
insert it into the mains IEC connector and push
it in until it locks in place. Then, check to make
sure it is locked in place. To remove it, release
its locking device and then pull it out. When
fitting or removing a Volex plug, always hold the
plug itself and never use the cable, as this may
damage it.
During operation, a minimum of two of its three
mains inlets must be connected and supplying
power.
When removing the equipment’s electric plugs
from the outlets, always hold the plug itself and
not the cable. Pulling out the plug by the cable
can damage it.
Never insert or remove an electric plug with wet
hands.
Do not connect/disconnect a mains power
connector to/from the PRO6 Control Centre
while power is being applied to it. Switch the
power off first.
Before switching the PRO6 Control Centre on or
off, make sure that all monitor loudspeaker
power amplifiers are turned off or muted.
