XP-25 Owner’s Manual
product’s safety ground, for your safety and the integrity of this
product the safety ground must never be defeated. Additionally this
product has filter 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-25 is built
voltage specific 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 affixed to the rear
panel of the XP-25’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 XP25 products are protected by a voltage specific type 3AG
fuse (1/4” x 1-1/4”). 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 1⁄2
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 (1/4” x 1-1/4”) may cause significant
physical damage to the fuse holder and put the product and your
safety at risk.
ADJUSTMENT:
In order to set the XP-25 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 specific 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
