Never attach or detach the 9 pin cable with the power supply, powered up from the
wall. Always unplug your XP-27 from line voltage prior to attaching or removing the
cable.
If you substitute an aftermarket power cord you need to be aware of the following.
The ground pin on the power cord provides this product’s safety ground, for your
safety and the integrity of this product the safety ground must never be defeated.
Additionally this product has fi lter components in the AC line that are designed to
shunt unwanted noise from the power-line to ground. Defeating the safety ground will
ultimately defeat some of the performance advantages built into this product.
To insure maximum performance and maximum safety use only power cords that
are grounded and carry all the necessary approvals and directives from the local
regulating authorities.
Lets talk about AC power requirements. Your new XP-27 is built voltage specifi c
to your market. Line voltage is determined at the time of construction and is not
changeable. The products voltage and current requirements will be indicated on a
tag affi xed to the rear panel of the XP-27’s power supply chassis. This tag will indicate
a nominal 100 volts, 120 volts, 220 volts, or 240 volts with allowances for normal
variations of the nominal indicated build voltage.
The AC Line Voltage in all instances will be 50 - 60 Hz. Please verify that that voltage
indicated on the product is consistent with the nominal voltage supplied at your
location.
All XP-27 products are protected by a voltage specifi c type fuse (5mm x 20mm slow
blow). For 100 Volts ac and 120 Volts ac the fuse will be 1 amp, for 220 Volts ac and
240 Volts ac the fuse will be ½ amp. In all instances the fuse will have a slow blow
time constant. Substitution of another time constant other than “slow blow” at the
same amperage will not harm this product, but we would not expect longevity from
the fuse element. It is not suggested that you substitute any other fuse type or fuse
rating, deviation from the indicated physical size of fuse (5mm x 20mm) may cause
signifi cant physical damage to the fuse holder and put the product and your safety
at risk.
ADJUSTMENT:
In order to set the XP-27 in a way which optimizes the performance of your phono-
cartridge it will be helpful though not absolutely necessary that you have some
information and set up suggestions on that specifi c cartridge. If you do not have
data on the cartridge and do not wish to re-invent the wheel, contact the dealer or
the Pass Laboratories factory. We will attempt to help you with that data, but by no
means do we have data for every cartridge arm combination ever built.
At the bare minimum you should know and have set the suggested optimal tracking
force for the cartridge and have already set the overhang and vta as per the
tonearm makers instructions, anti-skate and azimuth if possible.
