2. INSTALLATION
2.1 AC Mains Supply.
The mixer includes a separate T L Audio VR1000 power supply, and it is essential that only this
supply is used to power the mixer.
The power supply is fitted with an internationally approved 3 pin IEC connector. A mating socket
with power cord is provided with the unit, wired as follows:
Brown:
Live.
Blue: Neutral.
Green/Yellow: Earth (Ground).
All mains wiring should be performed by a qualified electrician with all power switched off, and the
earth connection must be used.
The power supply generates a certain amount of heat during use, which must be allowed to dissipate
from the ventilation slots and heatsink. Never cover the power supply or locate it near a source of
heat, for example a radiator or power amplifier. The PSU is fitted with a slow moving cooling fan,
which may generate a very small amount of mechanical noise.
The power supply should be connected to the mixer with the armoured multi core cable supplied,
before connecting the supply to the mains. The connectors should be inserted and secured into place
by tightening the locking rings. The cable is specially selected for the high voltage and current
requirements. Do not substitute any other cable or attempt to extend the cable supplied.
The connectors on this cable are polarised, so can only be plugged in one way – please do not try to
force the connector in if resistance is felt, since it can cause damage to the connector itself.
Before connecting the power supply to the mains, check that the voltage selector switch on the front
panel is correctly set. The unit may be set for 115V (accepting voltages in the range 110V to 120V,
60Hz AC), or to 230V (for voltages in the range 220V to 240V, 50Hz AC). The fuse required is
20mm anti-surge, 5AT for 230V or 10AT for 115V.
Warning:
attempted operation on the wrong voltage setting, or with an incorrect fuse, will
invalidate the warranty.
