For your protection please
read the following:
Water and moisture: Electrical devices should not be used near
water ( as per example, near a bathtub, washbasin, kitchen sink,
laundry tub, wet basement or swimming pool ). Care should be
taken such that objects do not have the opportunity to fall, and that
liquid is never spilled onto or into the device enclosure through
openings.
Power Sources: An electrical device must be connected to a mains
power source in strict accordance with the supplied product owner’s
manual. Please verify that the AC mains voltage specied in the
product manual matches those requirements indicated on the unit
and the AC voltage provided to your location by the power company.
Grounding: Adequate precautions should be taken so that the
grounding provisions built into an electrical product are never
defeated.
Power Cords: Pass Laboratories provides a power supply cord that
meets all legislated requirements for the market in which the product
was originally sold. If you choose to substitute an after-market
product we urge you to choose one that is fully safety rated by the
necessary local authority.
Power Cord Protection: Power supply cords should be routed so
that they are not likely to be walked on, abraded, or pinched by items
placed on or against them, paying particular attention to cords where
they enter plugs or exit from a device. Never under any circumstance
insert a cut or damaged power cord into a mains power socket.
Power and Signal: Cables should never be connected /
disconnected with equipment powered up. Failure to heed this
warning may damage or destroy equipment.
Ventilation: Power-ampliers run hot, but you should be able to
place your hands on them without discomfort. You must allow for
this heat in installation, by providing for free air circulation around
the product. Electronics should not be subjected to sources of
excessive radiant heat. Excessive heat can shorten the life of the
product and may cause the electronics to self-protect and shut down.
Servicing: To reduce the risk of re, electrical shock or other
injuries, the user should not attempt to service the device beyond
that which is described in the operating instructions. All other
servicing must be referred to qualied service personnel.

Introduction
The XP-10 is an ultra high quality line-stage audio preamplier featuring
remote control and internal power supply. The XP-10 minimizes the
number of components in the signal path, and yet retains exemplary
objective performance specications. It pushes the state of the art by
exploring how much subjective quality is obtainable with unique circuit
elements applied in innovative ways.
The Pass Laboratories XP-10 along with the XP-20 pre-ampliers are the
natural descendants to the highly acclaimed and successful X series of Pass
Laboratories line-stages represented by models X0.2, X1 and X2.5.
The X series pre-ampliers have received many highly respected and
well-deserved accolades over the past 11 years…. justiably so. More
importantly they have provided a solid foundation from which the current
and newest product has evolved.
These new pre-amp offerings from Pass Laboratories objectively sound and
measure signicantly better than their immediate predecessors.
The new XP series pre-ampliers are more true to state of the art
recordings than our previous line level product. Given quality recordings,
these pre-ampliers sound more dynamic, bass lines are more clearly,
cleanly, and accurately delineated, helping eliminate un-necessary one
note bass; instruments and voice are presented in a more rened spatial
envelope, and with better spectral balance.
Fine nuances and details, which frequently have gone un-noticed, now
become apparent -- even in loud and highly complex musical passages.
The simple truth is that a decade of knowledge and experience gained,
coupled with new component technology, has enabled both enhanced
performance and listening satisfaction over the building blocks we had
available when the original X series pre-ampliers came to market. Pass
Laboratories has not been shy about taking advantage of these circuit
innovations and new components in these new pre-ampliers. You
will hear, and appreciate, these signicant sonic improvements as you
experience the XP series product.
Collectively, audiophiles tend to listen quite a bit differently today, than they
did when the original X preamps were created, and the XP line of product
have all been designed to reect those changes in listening style.
Pass Laboratories has redesigned the remote control to allow direct access
to the most frequently wanted control functions, thus simplifying and
enhancing product operation. The new remote control codes have been
carefully selected to minimize the impact on other remote controlled

electronic devices, allowing for more carefree product placement.
Volume control steps on the new pre-ampliers are more numerous and
generally of smaller increments, giving the listener a wider choice of
listening levels to better accommodate the wildly-uctuating levels of
current, verses legacy, recordings.
Changing lifestyles dictate that many audiophiles now share family space
where music may be an adjunct to other activities. To better serve the
needs of these listeners, these new pre-ampliers allow for signicantly
more precise volume steps and greater attenuation at the very lowest
volume levels.
So that these very low-volume listening levels have real world practicality,
the noise oor and very ne detail retrieval of these new pre-ampliers is
dramatically superior to our previous product.
Frequently, the perception of increased detail comes at the cost of equally
increased grain or edginess in the music. With this new pre-amplier,
hundreds of hours of thoughtful listening and careful adjusting have
produced a product where the enhanced detail simply comes through
as greater spatial renement and dynamic accuracy; without any loss
of musicality. Bass denition is better than in pervious models, highly
dynamic passages typically have more weight, a more accurate leading edge
with increased control and the spectral balance is more nely integrated top
to bottom.
ADVISORY
We sincerely believe these are simply the best pre-ampliers Pass
Laboratories has ever built! Thank you for giving us the opportunity to
prove this claim.
There is an Extremely Small (but Non-zero) Chance That, Through a
Process Know as Tunneling, This Product May Spontaneously Disappear
from Its Present Location and Reappear at Any Random Place within the
Universe, Including Your Neighbor’s Domicile.
The Manufacturer Will Not Be Responsible for Any Damages,
Inconvenience or Mental Anguish That May Result From These Spacetime
Perturbations.
There is a much higher probability that when you rst plug your new
pre-amp into the wall and listen that you will not be experiencing the full
measure of performance this product is capable of. These are high bias
Class A topology circuits and their performance is largly temperature
dependendt. We expect these circuits to heat up slowly through normal
operation, do not attempt to augment that heating by any articial means.
